Our top picks
Best overall
1. Milwaukee M12 FUEL Hatchet Pruning Saw, 6 inch
Best for: Regular pruning of hardwood limbs and long sessions
Best for light pruning
2. WORX 20V 5 inch Pruning Saw
Best for: Shrubs and small limbs, with no battery system yet
Best for small branches
3. Saker Mini Chainsaw, 4 inch
Best for: Small branches, storm debris and odd jobs
The best mini chainsaw for most pruning is the Milwaukee M12 FUEL Hatchet Pruning Saw, a 6 inch saw linked here as the kit with an M12 4.0Ah battery and a charger. Bob Vila named it the best mini saw in its test of small chainsaws, where it made 81 cuts through wood 2 to 4 inches across on one charge. For lighter pruning, the WORX 20V 5 inch Pruning Saw comes with its battery and weighs about 3.9 pounds with it, by its listing. For small branches and odd jobs, the Saker Mini Chainsaw with a 4 inch bar was the lightest of the nine saws in Outdoor Life's timed test.
The other three picks are for people who already own a battery system: Greenworks 24V, Makita 18V LXT or Craftsman V20. Below the picks, one table sets out what the hands-on tests measured, a second puts what each manual says about one hand or two side by side, and a third shows how thick a branch each saw is meant to cut, by whose word. The safety rules on this page come from the saws' own manuals, OSHA and university extension services, and the pruning advice comes from extension services at Iowa State, Missouri and Colorado State, each named where it appears.

The best mini chainsaws, by job
1. Milwaukee M12 FUEL Hatchet Pruning Saw, 6 inch: best overall
Best overall
Best for: Regular pruning of hardwood limbs and long sessions
Milwaukee M12 FUEL Hatchet Pruning Saw, 6 inch
- Bar: 6 inch
- Battery: Milwaukee M12, 4.0Ah in the kit
- Oiling: Automatic
Bob Vila's best mini saw, which made 81 cuts through wood 2 to 4 inches across on one charge and oils its own chain.
Milwaukee's M12 FUEL Hatchet is a 6 inch pruning saw that runs on Milwaukee's 12 volt M12 batteries. It is linked here as the 2527-21 kit, which comes with an M12 XC 4.0 battery and a charger, by Milwaukee's kit page. Milwaukee says it has the power to cut 3 inch hardwoods, makes up to 120 cuts per charge and weighs less than 5 pounds with its battery, and that it was built for landscape maintenance professionals. By the same page it has a brushless motor, an automatic oiler with a see-through oil reservoir, all-metal bucking spikes and a chain tensioner that is easy to reach.
Why it is the pick: Bob Vila named it the best mini saw in its test of eight small chainsaws, and it was the only saw in that test with a bar under 10 inches. The testers ran it on a 12 volt 4Ah battery and made 81 cuts through wood 2 to 4 inches across on a single charge, and they described the cuts as smooth, fast and clean. At 4.1 pounds it felt well balanced to them, and the short bar reached into tight spots without nicking the branches they wanted to keep. Bob Vila describes it as built for one-handed use; Milwaukee's own manual, quoted under one hand or two, says to keep both hands on the saw when pruning.
Good to know: the safety switch sits at the very edge of thumb reach, which Bob Vila says people with smaller hands may find hard to work. Milwaukee's manual says to empty the oil tank and lightly oil the chain whenever you store it. Milwaukee says the saw is optimized for its 6 inch bar and chain and advises against fitting a different size, and it sells an 11/64 inch (4.5 mm) round file for sharpening this chain. On November 2, 2026 this kit was sold by a third-party seller.
2. WORX 20V 5 inch Pruning Saw: best for light pruning
Best for light pruning
Best for: Shrubs and small limbs, with no battery system yet
WORX 20V 5 inch Pruning Saw
- Bar: 5 inch
- Battery: WORX 20V Power Share, 2.0Ah in the kit
- Oiling: By hand
A 5 inch saw that Gardeners' World tested in its UK version, sold with its battery and charger and guarded over the bar and the hand.
The WORX WG324 is a 5 inch pruning saw on WORX's 20 volt Power Share battery, linked here as the kit with a 2.0Ah battery, a quick charger and a bar sheath, by its listing. The listing puts it at 3.9 pounds with the battery and up to 100 cuts of 2 inch wood on a charge. WORX's page adds an offset bar and chain so you can see your cut line, a guard over the top of the bar that swings out of the way when you cut from above and that you pull back by hand to cut from below, a hand guard, a lock-out switch, a tensioning tool stored on the saw, and a 3-year warranty on the tool. The battery also runs WORX's 20V, 40V and 80V Power Share tools.
Why it is the pick: Gardeners' World tested the UK version, the WG324E, with a 12 cm bar and a 2.0Ah battery, and found it compact and light yet strong enough to get through branches quickly, with about 40 minutes of running time on a charge. For shrubs and small limbs, it is a tested saw from a maker with a wide range of battery tools, and it comes with the battery and charger, so it suits someone who does not own a battery system yet.
Good to know: it has no automatic oiler; WORX says to oil the bar and chain by hand with any standard bar and chain oil, much as you would oil a bicycle chain. WORX's page talks of easy one-hand operation and limbs up to 6 inches, while its manual says to hold the saw in both hands and to cut branches no thicker than the bar is long; see the tables under one hand or two and branch size. On November 2, 2026 this kit was sold by Amazon.com.
3. Saker Mini Chainsaw, 4 inch: best for small branches
Best for small branches
Best for: Small branches, storm debris and odd jobs
Saker Mini Chainsaw, 4 inch
- Bar: 4 inch
- Battery: Saker 20V, two in the kit
- Oiling: By hand
The lightest of the nine saws in Outdoor Life's test, which got through a 4 inch oak log in 15.3 seconds.
Saker's mini chainsaw is a small 20 volt saw with a 4 inch bar, linked here in the kit with two 1500mAh batteries, by its listing. The listing puts the saw at 1.1 kg (about 2.4 pounds) with a battery, says you must press the safety lock before the trigger will start it, and gives a 365-day warranty. There is no automatic oiler.
Why it is the pick: Outdoor Life's tester expected a saw like this to fail his test, and it did not. It was the lightest of the nine saws in that test at 2 pounds 8 ounces (2.5 pounds) with its battery, it cut through a 4 inch oak log in 15.3 seconds, close to Stihl's 4 inch GTA 26 at 14.2 seconds, and it made 22 cuts before it overheated, with charge still left in the battery. He then kept it for a year for clearing brush and trails, and wrote in his follow-up review that it handled everything he threw at it. For trimming small branches and cutting up storm debris, it is the lightest of the five picks here with a published weight.
Good to know: the battery overheated and the chain kept working loose in Outdoor Life's test, and the tester found the safety lock awkward to reach with one hand on the saw. Because there is no automatic oiler, he says to oil the bar and chain as you work, at least once each battery charge. The short bar and the plastic guard make the chain hard to sharpen, so he suggests a kit with spare chains. Outdoor Life tested this 4 inch saw; Saker's "upgraded" 6 inch model overheated sooner and cut more slowly in the same tester's hands, which is why the 4 inch one is linked here. Saker's listing says to let the saw cool completely if it gets hot. On November 2, 2026 this kit was sold by Saker.
4. Greenworks 24V 6 inch Mini Chainsaw: best for Greenworks 24V owners
Best for Greenworks 24V owners
Best for: Anyone who already runs Greenworks 24V tools
Greenworks 24V 6 inch Mini Chainsaw
- Bar: 6 inch
- Battery: Greenworks 24V, 2.0Ah in the kit
A 6 inch saw at 3.4 pounds with its battery by Greenworks' figures, with chain tensioning that needs no tools.
Greenworks' 24 volt mini chainsaw has a 6 inch bar and chain and is sold with a 2.0Ah battery and charger, by its listing. Greenworks' page puts it at 3.4 pounds with the battery, with a brushless motor, chain tensioning that needs no tools, a chain speed of 25.6 feet per second and 105 cuts per charge, with a limited warranty of 3 years on the tool and battery. The listing adds a security lock against accidental starts and a push-button start, and says the battery runs more than 200 Greenworks tools.
Why it is the pick: if you already run Greenworks 24V tools, the batteries you own will power it, and it is a full 6 inch saw at 3.4 pounds with its battery by Greenworks' figures. No hands-on test we read covered this 6 inch model. Gardeners' World tested a Greenworks 24V mini pruner sold in the UK with a 10 cm bar and found it comfortable and well balanced, though it thought the bar small for the size of the body; that is a different saw. This pick rests on Greenworks' page and the listing.
Good to know: the listing says it cuts 6 inch logs with ease, but for a single-pass cut Greenworks' own FAQ wants the log about 2 inches thinner than the bar, which for a 6 inch bar is about 4 inches. The listing does not say how the chain is oiled; Greenworks' FAQ says its saws take standard bar and chain oil and that all chainsaws slowly seep oil in storage. On November 2, 2026 this kit was sold by Amazon.com.
5. Makita XCU14Z 6 inch Pruning Saw: best for Makita 18V owners
Best for Makita 18V owners
Best for: Anyone who already has Makita 18V LXT batteries
Makita XCU14Z 6 inch Pruning Saw
- Bar: 6 inch
- Battery: Makita 18V LXT, not included
- Oiling: Automatic
A tool-only 6 inch saw that oils its own chain, which Makita puts at up to 140 cuts through 2 inch cedar per 2.0Ah charge.
Makita's XCU14Z is a 6 inch pruning saw on Makita's 18V LXT batteries, sold as the tool only, with no battery or charger in the box, by Makita's page. Makita calls it a "compact handheld saw for pruning and light limbing," with a brushless motor, chain adjustment that needs no tools, a retractable guard and seals against dust and water that it calls XPT. It puts the saw at 3.7 pounds with a battery and rates it at up to 140 cuts through 2 inch cedar per charge of an 18V LXT 2.0Ah battery. The chain in the box is a low kickback chain, and the manual says the chain is oiled automatically while the saw runs.
Why it is the pick: for anyone with Makita 18V batteries already, it adds a pruning saw without another battery and charger, and it oils its own chain. No hands-on test we read covered it; this pick rests on Makita's page, its manual and the listing. Makita's kit with a battery showed low stock on Amazon on November 2, 2026.
Good to know: Makita's manual says to hold it by the rear handle with one hand and the front handle with the other at all times, and never to run it in a tree, on a ladder or from a rooftop. It also says to use botanical chain oil when pruning trees, because mineral oil may harm them. The oil tank holds 55 ml (1.9 fl oz). On November 2, 2026 this listing was sold by Amazon.com.
6. Craftsman V20 6 inch Pruning Chainsaw: best for Craftsman V20 owners
Best for Craftsman V20 owners
Best for: Anyone who already runs Craftsman V20 tools
Craftsman V20 6 inch Pruning Chainsaw
- Bar: 6 inch
- Battery: Craftsman V20, 2.0Ah in the kit
A 6 inch saw with a tip guard that its listing gives a cut capacity of up to 4 inches and up to 85 cuts.
Craftsman's CMCCS320D1 is a 6 inch pruning chainsaw on Craftsman's V20 battery, linked here as the kit with a 2.0Ah battery, a charger, a sheath and a wrench, by its listing. The listing gives a cut capacity of up to 4 inches with the 6 inch bar and up to 85 cuts, an integrated tip guard for control on upper cuts, bolt lock chain tensioning, a sheath that holds the wrench, and a 3 year limited warranty. Craftsman says it is 50 percent more compact and 14 percent lighter than its older CMCCSL621B.
Why it is the pick: for a garage already stocked with V20 tools, it is a pruning saw on the same battery, with a guard at the tip of the bar. Outdoor Life, writing about the same kind of tip guard on DeWalt's 8 inch pruning saw, says it is meant to prevent kickback and keeps the nose of the bar out of the dirt. No hands-on test we read covered this Craftsman, and we did not find Craftsman's own product page; this pick rests on its listing.
Good to know: the listing does not give a weight or say how the chain is oiled, so check the manual in the box before the first cut. On November 2, 2026 this kit was sold by Amazon.com.
How we chose these
We compared the mini chainsaws in Amazon's catalog by what their makers say they are: the bar length, the battery, the weight, how the chain is oiled and what they are meant to cut. For each pick we read the Amazon listing, the maker's page for Milwaukee, WORX, Greenworks and Makita, and the operator's manual for Milwaukee, WORX and Makita. Then we read the hands-on tests. Outdoor Life's test of nine mini chainsaws timed three cuts through a 4 inch oak log for each saw with a 4 to 8 inch bar, then counted cuts until the battery died or the saw overheated, then spent a day clearing trails with them; the same tester later reviewed the Saker after a year of use. Bob Vila tested eight small chainsaws on logs of about 4 to 12 inches, one of them a mini saw. Gardeners' World tested mini chainsaws sold in the UK by pruning trees and cutting firewood. Pro Tool Reviews' mini chainsaw page would not load for us.
Our floor, for the picks and for the notes under Also considered: in stock on Amazon and sold new, when we checked on November 2, 2026. Each pick met it. Bars, batteries, weights and cut counts come from the maker pages and listings, named where they appear. Safety rules come from the manuals, from OSHA's chainsaw fact sheet and from the University of Missouri and West Virginia University extension services; pruning advice comes from extension services at Iowa State, Missouri and Colorado State.
Also considered: mini chainsaws that missed the list and why
Milwaukee M18 FUEL Hatchet 8 inch Pruning Saw. Outdoor Life's best overall: it cut the 4 inch oak log in 6.7 seconds, made 92 cuts on a 5Ah battery and later cut through a 7 inch maple, and it was the one pruner-style saw in that test with an automatic oiler, and the one with no plastic cover on top of the chain. It is also much heavier, at 6 pounds 13 ounces with the battery as the tester weighed it. Milwaukee gives its largest cut as 7.5 inches. It is sold without a battery. It was not in stock on Amazon on November 2, 2026.
Stihl GTA 26. Outdoor Life's pick for backyards, with the best ergonomics in its test and an extension pole sold for it, though its small battery managed only 12 cuts through the oak log; Gardeners' World's top mini chainsaw, with a short 25 minute running time. It missed the list because the two picks for lighter jobs outlasted it: in Outdoor Life's test the 4 inch Saker was nearly as fast through the oak log and made 22 cuts to the Stihl's 12, and Gardeners' World gives the UK version of the WORX about 40 minutes a charge, to the Stihl's 25.
DeWalt 20V MAX 8 inch Pruning Chainsaw (DCCS623B). In Outdoor Life's test it was as fast as the M18 Hatchet through the oak log but made 37 cuts to the Milwaukee's 92, and it has a tip guard on the nose of the bar. It was not in stock on Amazon on November 2, 2026.
Ryobi One+ 18V 6 inch pruning mini chainsaw. Outdoor Life found it quick and light, with a bar 2 inches longer than the Saker's and Stihl's and a plastic cover on top of the chain, but its 2Ah battery ran down fast (27 cuts). The one Amazon listing we found, a bulk-packaged brushless kit from a third-party seller, showed low stock on November 2, 2026 and may not be the model Outdoor Life tested.
Saker 6 inch mini chainsaw. Saker's longer-bar model. Outdoor Life's tester found it overheated sooner and cut more slowly than the 4 inch Saker (pick 3), and suggests a Milwaukee or DeWalt with an 8 inch bar for anyone who wants a longer bar.
Top-handle saws (Echo DCS-2500T, Milwaukee M18 top handle). Outdoor Life tested both and notes this kind of saw "is usually used by professional arborists for in-tree work"; it lists the Milwaukee as only for experienced chainsaw users. Bob Vila adds that a short-bar top-handle saw can be harder to predict and more dangerous for a new user. They are not pruning saws for the yard, so they are not on this list.
What the hands-on tests measured
Three hands-on tests covered saws on this page. Outdoor Life timed each small saw through a 4 inch oak log, averaged three cuts, then kept cutting until the battery died or the saw overheated. Bob Vila cut rounds off logs of about 4 to 12 inches with eight small chainsaws and counted cuts per charge. Gardeners' World pruned trees and cut firewood with mini chainsaws sold in the UK. The table sets out what each printed for the saws on this page and the ones under Also considered.
| Saw | Tester and result | Good to know | Here |
|---|---|---|---|
| Milwaukee M12 FUEL Hatchet, 6 inch | Bob Vila: best mini; 81 cuts of 2 to 4 inch wood on one charge; 4.1 pounds | Safety switch at the edge of thumb reach for smaller hands | Pick 1 |
| WORX WG324E, 12 cm (UK version) | Gardeners' World: compact and light, quick through branches; about 40 minutes a charge | Oiled by hand; no automatic oiler | Pick 2 (the US WG324) |
| Saker, 4 inch | Outdoor Life: 15.3 seconds; 22 cuts before overheating; 2 pounds 8 ounces | Battery overheated; chain worked loose; safety lock awkward one-handed | Pick 3 |
| Milwaukee M18 FUEL Hatchet, 8 inch | Outdoor Life: best overall; 6.7 seconds; 92 cuts; 6 pounds 13 ounces | Heavy; no plastic guard over the chain | Also considered |
| Stihl GTA 26, 4 inch | Outdoor Life: 14.2 seconds; 12 cuts; best ergonomics. Gardeners' World: its top mini chainsaw | Battery ran down fast; touchy chain tensioner; 25 minute running time | Also considered |
| DeWalt 8 inch pruning saw | Outdoor Life: 6.7 seconds; 37 cuts | Far fewer cuts per charge than the M18 Hatchet | Also considered |
| Ryobi 6 inch | Outdoor Life: 10.9 seconds; 27 cuts | Battery ran down fast | Also considered |
What it shows: the M18 Hatchet on its 5Ah battery made far more cuts than any other pruner-style saw in Outdoor Life's test, and the two 4 inch saws were the slowest pruner-style saws through the 4 inch log but also the two lightest saws in the test. Outdoor Life's own summary is that every saw in its test could do backyard and garden jobs, and that none of them is the right tool for bucking firewood logs. The Bob Vila count is for 2 to 4 inch wood and the Outdoor Life counts are for a 4 inch oak log, so read the two sets of numbers separately.
One hand or two? What the manuals say
Mini chainsaws are often sold as one-hand tools. The manuals we read say otherwise. Here is what each source says, by whose word:
| Source | What it says |
|---|---|
| Milwaukee's manual (pick 1) | For pruning, work slowly, both hands on the saw, firm grip; extreme caution during one-handed operations |
| Bob Vila, on pick 1 | Built for one-handed use; its general advice is that a saw should be held in two hands whenever it cuts |
| WORX's page and listing (pick 2) | A slim, light design for easy one-hand operation |
| WORX's manual (pick 2) | Both hands: the right on the main grip, the left on the second grip |
| Saker's listing (pick 3) | It can be used with one hand |
| Makita's manual (pick 5) | Always both handles, rear and front, one hand on each |
| Outdoor Life | The light saws are easy to run one-handed, but that puts your other hand and arm at risk too |
| Gardeners' World | "Although you can use a mini chainsaw one-handed, it's much safer to use both hands" |
| OSHA chainsaw fact sheet | "Keep both hands on the handles and maintain secure footing" |
What it shows: the one-hand wording is on sales pages, listings and in testers' notes; the three operator's manuals we read and OSHA say both hands. Milwaukee's manual covers the moments when one hand is needed, such as steadying a branch: "Keep free hand clear of the chain and out of the cutting path," hold the branch firmly so the saw does not skate or bounce, stay below shoulder height, do not reach too far or cross your arms, and cut away from your body. It also warns that thin branches, vines and small brush can catch the chain and whip toward you, and it suggests hedge trimmers or brush cutters for that work.
How thick a branch can a mini chainsaw cut?
Often less than the sales copy suggests. The makers' sales copy and their own manuals and FAQs do not always agree, so here is each figure by whose word.
| Saw | Bar | What the maker or listing says it cuts | What a manual, FAQ or tester says |
|---|---|---|---|
| Pick 1, Milwaukee M12 Hatchet | 6 inch | 3 inch hardwoods; up to 120 cuts a charge (Milwaukee) | Bob Vila: 81 cuts of 2 to 4 inch wood on a charge |
| Pick 2, WORX WG324 | 5 inch | Limbs up to 6 inches (WORX's page); up to 100 cuts of 2 inch wood (listing) | WORX's manual: branches up to the length of the guide bar |
| Pick 3, Saker | 4 inch | Not stated on its listing | Outdoor Life: not meant for larger limbs; eased along, it got through 6 inch limbs but stalled under too much pressure |
| Pick 4, Greenworks 24V | 6 inch | 6 inch logs (listing); 105 cuts a charge (Greenworks' page) | Greenworks' FAQ: for one pass, a log about 2 inches smaller than the bar |
| Pick 5, Makita XCU14Z | 6 inch | Up to 140 cuts through 2 inch cedar per 2.0Ah charge (Makita) | Makita: for pruning and light limbing |
| Pick 6, Craftsman V20 | 6 inch | Up to 4 inch cut capacity; up to 85 cuts (listing) | Not stated beyond the listing |
The general rule from both a tester and an extension service is the bar: Outdoor Life's rule of thumb is not to saw a limb thicker than the saw's bar, and the University of Missouri Extension says not to try to cut material larger than the guide bar. For a live tree, the limit is lower still. Colorado State University Extension says that ideally every pruning cut is on a branch 2 inches across or less, because smaller cuts close over faster, and that a cut over 4 inches raises the risk of decay getting into the tree. The University of Missouri Extension's forestry specialist says to think carefully before taking off a branch over 2 inches, and the tree service head Bob Vila interviewed, Kaustubh Deo, says a homeowner making cuts over 4 inches on a live tree should be working with an arborist.
Pruning with a mini chainsaw: when and how to cut
When: the University of Missouri Extension's forestry specialist puts the best time to prune trees in the dormant season, from leaf fall in autumn until the leaves come out in spring, with only light, corrective pruning in summer, such as after a storm. That makes late fall and winter the main season for a pruning saw.
How: for any branch thicker than 1 1/2 inches, Iowa State University Extension gives a three-cut method that keeps the bark from tearing down the trunk:
- Cut upward from the underside, 6 to 12 inches out from the trunk or main branch, about a third of the way through.
- Cut down from the top, 1 to 2 inches farther out than the first cut. The branch breaks off between the two cuts, and the undercut stops it from peeling a strip of bark as it falls.
- Take off the stub with a last cut just past the branch collar, without cutting into it or into the raised ridge of bark where branch meets trunk.
The branch collar is the swollen area at the base of a branch where trunk and branch tissue overlap, by Colorado State University Extension, and inside it is a zone that helps stop decay spreading into the trunk; cutting into or nicking the collar can leave the wound open to decay. The University of Missouri Extension adds: never cut level with the trunk, and a cut about an inch across, made properly, can heal over within two years, sometimes in the first. If you run Makita's saw (pick 5), its manual asks for botanical chain oil when pruning trees, since mineral oil may harm them.
For branches under an inch or two across, loppers do the job by hand; our loppers guide covers them, and our pruning saw guide covers folding and fixed hand saws for quiet, careful cuts on a few limbs.
Safety gear and rules from OSHA and extension services
None of what follows is our own rule; each line is the source's. OSHA's chainsaw fact sheet says to check the controls, chain tension, bolts and handles before you start, to make sure the safety devices work, to clear dirt, debris and small limbs from the saw's path and look for nails or other metal, not to work alone, and to wear proper protective equipment. While cutting, it says to grip the handles with both hands, feet secure, to be prepared for kickback and avoid cutting in the kickback zone, not to cut directly overhead, and to take breaks, since fatigue raises the risk of an accident.
The University of Missouri Extension describes kickback as what happens when the tip of the bar strikes something and the bar shoots back toward the operator in a flash; it says a low-kickback chain, which smaller consumer saws must come with, does not mean kickback cannot happen. It also notes that a saw chain moves at as much as 55 miles per hour, and it lists the gear: ballistic nylon chaps or leggings, safety glasses, earplugs or muffs against noise over 90 decibels, a hard hat, high-top shoes, and gloves whose palms resist slipping. It says not to run a saw above shoulder level.
On ladders, the sources are blunt. Makita's and WORX's manuals rule out running their pruning saws "on a ladder, from a rooftop, or any unstable support," in WORX's words, and Makita's adds working in a tree; Milwaukee's manual calls cutting from a ladder extremely dangerous and says to leave that work to professionals. West Virginia University Extension warns homeowners not to climb a ladder into a tree to cut overhead, and to call a certified arborist instead. It adds that protective gear will not prevent an accident, but it may keep one from becoming a serious injury.
Outdoor Life's tester puts it plainly: "Small does not mean safe." With a mini chainsaw your hands work nearer the chain, he notes, so he says to mind where they are and always wear the right protective gear.
Battery, oil and chain care
Oil: picks 1 and 5 oil their own chains: Milwaukee lists an automatic oiler, and Makita's manual says the chain is oiled automatically as the saw runs. The WORX (pick 2) and the Saker (pick 3) are oiled by hand: WORX says to apply standard bar and chain oil the way you would oil a bicycle chain, and Outdoor Life's tester oiled the Saker as he worked, at least once a charge. The Greenworks and Craftsman listings do not say. Greenworks' FAQ says all chainsaws slowly seep oil in storage and suggests storing them with as little oil in the reservoir as you can, lying flat with a rag beneath, and Milwaukee's manual says to empty the oil tank before you store the saw.
Chain tension and sharpness: OSHA says to check chain tension before you start, and the WORX and Makita manuals warn that a chain that is not tensioned or oiled properly may break or raise the chance of kickback. Milwaukee sells an 11/64 inch round file for the Hatchet's chain. Outdoor Life found the Saker's chain hard to sharpen behind its guard, so spare chains are the easier route there. Our chainsaw sharpener guide matches files and sharpeners to chain sizes.
Heat and batteries: the Saker overheated in Outdoor Life's nonstop cutting test before its battery ran out, and Saker's listing says to let the saw cool completely before you carry on. For long jobs, a second battery is the testers' usual answer: Outdoor Life suggests one for the Ryobi and the Saker, and Gardeners' World says more batteries let one charge while you work with the other.
Mini chainsaw, pruning saw, pole saw or a full-size chainsaw?
A mini chainsaw is for limbs you can reach from the ground, between the size of a lopper's job and a log: Bob Vila calls mini saws best for pruning duty, and Makita calls its saw a "compact handheld saw for pruning and light limbing." For branches above your shoulders, every manual we read says not to reach up with the saw, which is the job of a pole saw; our pole saw guide covers cordless, manual and gas models. For firewood and fallen trees, Outdoor Life says none of the mini saws it tested is ideal for bucking logs, and the University of Missouri Extension puts an 8 to 14 inch guide bar at the size for limbing, small logs and taking down small trees. Our battery chainsaw guide covers full-size cordless and corded electric saws, and our chainsaw guide for homeowners covers 14 to 18 inch battery and gas saws for bigger wood.

Frequently asked questions
What is the best mini chainsaw?
For most pruning, the 6 inch Milwaukee M12 FUEL Hatchet Pruning Saw, which Bob Vila named the best mini saw in its test, where it made 81 cuts through 2 to 4 inch wood on one charge. For lighter jobs, the WORX 20V 5 inch Pruning Saw; for small branches, the 4 inch Saker, the lightest saw in Outdoor Life's test; and if you already own Greenworks 24V, Makita 18V LXT or Craftsman V20 batteries, the saw that runs on them.
Can you use a mini chainsaw with one hand?
Some sales pages say so, but the Milwaukee, WORX and Makita manuals all say to hold the saw with both hands, and OSHA says to keep both hands on the handles. Gardeners' World says a mini chainsaw can be used one-handed but that it is much safer to use both hands, and Milwaukee's manual says to use extreme caution during one-handed operations.
How thick a branch can a mini chainsaw cut?
By the makers' own figures, 3 inch hardwood for Milwaukee's 6 inch Hatchet and up to 4 inches for Craftsman's 6 inch saw; WORX's page says limbs up to 6 inches for its 5 inch saw, but its manual says no thicker than the bar is long. The University of Missouri Extension says not to cut material larger than the guide bar, and Greenworks says a one-pass cut needs a log about 2 inches smaller than the bar. On live trees, Colorado State University Extension says pruning cuts ideally stay at 2 inches or less.
Are mini chainsaws safe?
Gardeners' World's answer is yes when they are used properly with the right safety gear, and it warns that improper use can lead to devastating injuries. Outdoor Life's tester warns that small does not mean safe, since your hands work nearer the chain, and the manuals and OSHA call for both hands, protective gear, secure footing and no cutting above shoulder height or from a ladder. West Virginia University Extension suggests calling a certified arborist for anything you cannot reach from the ground.
Do mini chainsaws need bar oil?
The saws on this page do. The Milwaukee and Makita saws oil the chain from a tank as they run. The WORX and the Saker are oiled by hand with bar and chain oil, which Outdoor Life's tester did at least once a battery charge. Makita's manual asks for botanical chain oil when pruning trees, because mineral oil may harm them.
Is a mini chainsaw good for pruning trees?
For limbs you can reach from the ground, yes: Bob Vila calls mini saws best for pruning duty. Use the three-cut method Iowa State University Extension describes for branches over 1 1/2 inches, cut just outside the branch collar, and prune in the dormant season, which the University of Missouri Extension puts from leaf fall to leaf out.
Can a mini chainsaw cut firewood?
Small rounds, slowly. Outdoor Life says none of the mini saws it tested is ideal for bucking logs for firewood, and Gardeners' World suggests a sawhorse to hold logs so your hands stay on the saw. For real firewood, a saw with an 8 to 14 inch bar is the size the University of Missouri Extension gives for small logs.
When is the best time to prune trees?
The University of Missouri Extension's forestry specialist says the dormant season, from leaf fall in autumn until the trees leaf out in spring, with only light corrective pruning in summer, such as after a storm.
