Proper chainsaw use requires full safety gear, starting on stable ground with the brake engaged, a two-handed grip, and avoiding the bar tip to prevent kickback.
Mastering how to properly use a chainsaw means locking in the safety sequence — the right gear, the right start, the right stance, and the right cut — before you ever pull the starter cord. This guide runs through every step in order, drawn from OSHA standards and university extension training that professional loggers follow.
Before going further, make sure the saw itself is up to the job — the best chainsaws for cutting trees covers models for everything from light trimming to heavy felling.
What Safety Gear Do You Need Before Starting?
Full personal protective equipment is non-negotiable. A single kickback or dropped saw can turn a routine cut into an ER visit, and the gear is cheap insurance compared to the alternative. OSU Extension’s training footage, dated March 2023, lists the same minimum set that Cornell and OSHA recommend.
| Gear Item | What It Protects | Key Detail |
|---|---|---|
| Hard hat with face shield and safety glasses | Head, face, and eyes | Falling branches and flying debris are the main threats |
| Hearing protection (earmuffs or plugs) | Ears | Gas saws run at 110+ dB — permanent damage is fast |
| Safety gloves | Hands | Improves grip and protects against minor slips |
| Chainsaw chaps or pants | Legs | Kevlar fibers jam the chain on contact instead of your skin |
| Steel-toed boots with hard shell | Feet and ankles | Regular boots won’t stop a dropped saw |
| Long sleeves and snug-fitting clothes | Arms and torso | Loose fabric snags on the bar and pulls you into the chain |
Stow the saw if any piece of PPE is missing. There is no safe shortcut around clothing.
Pre-Start Inspection Checklist
A five-minute inspection before every use catches the problems that cause kickbacks and stalls. Walk through each point before you add fuel or touch the starter cord.
Check the controls first — the throttle, chain brake, and on-off switch should all move freely and snap back. Look at chain tension next: the drive links should sit snug in the bar groove, and when you pull the chain away from the bar, the tie straps shouldn’t lift more than an eighth of an inch. Cornell’s safety toolbox talk also says to verify the chain is sharp — dull chains overheat, smoke, and push rather than cut, which forces you to muscle the saw and lose control. Top off the bar oil reservoir before every session; running dry welds the chain to the bar in under a minute. Finally, clear the cutting area of dirt, gravel, loose bark, and small rocks — anything the chain touches that isn’t wood can kick it back toward you. If the tree has been downed or damaged, look for embedded nails, spikes, or fencing wire before committing to a cut.
How Do You Start a Cold Chainsaw Safely?
The correct start sequence keeps the chain locked and the saw stable so a kickback or runaway saw never happens before you’re ready to cut. Start on flat ground or a firm stump — never drop-start by holding the saw in the air with one hand.
Engage the chain brake by pushing it forward until it clicks. On gas saws, turn the choke on and press the decompression button if your model has one. Place your right boot toe through the rear handle C-shape to pin the saw to the ground, or wedge the handle between your thighs. Grip the front handlebar with your left hand and press down firmly. Pull the starter cord with your right hand until you feel resistance, then give a smooth, strong pull — full extension, not a short jerk. When the engine fires once, push the choke in and pull again until the saw runs. Blip the throttle to confirm the chain brake releases and the chain moves freely. Husqvarna’s training manual stresses that the chain brake must stay engaged until you’re standing in cutting position with both hands on the handles.
Proper Cutting Technique
Once the saw is running, how you hold it, where you stand, and where the bar tip points determine whether you finish the job safely or end up in the emergency room. The basics come from forestry training that has been standard for decades.
Grip and stance. Left hand on the front handle, right hand on the rear — even if you’re left-handed. Wrap your thumb all the way around the handle; a thumb-on-top grip gets ripped off on kickback. Stand with your feet shoulder-width apart, left foot slightly forward, knees bent. Keep the saw at waist level and position your body to the side of the cutting plane. Never cut above shoulder height — that angle removes controlled leverage and aims the kickback path straight at your head. Never cut between your legs or while standing on a ladder.
The cut itself. Let the chain reach full speed before touching wood. Use a rocking motion — drop the rear spurs into the cut first, then pivot the nose down — rather than a back-and-forth sawing push. The most dangerous part of the bar is the upper quadrant of the tip; when that section contacts anything solid, the saw pivots upward toward your face in under a tenth of a second. Keep the bar tip in contact with wood only at the lower portion. Every time you reposition or walk more than a few steps, engage the chain brake or shut the saw off.
Watching for hidden dangers. Branches under tension — spring poles — can whip the saw back at you when cut. Approach them by making a shallow relief cut on the compression side before the final cut on the tension side. If a cut tree gets hung up in another tree, never cut the second tree to free it. That maneuver kills more homeowners than almost any other chainsaw mistake. Call for professional help instead.
Common Chainsaw Mistakes That Cause Injuries
The injury statistics cluster around a handful of repeatable errors. Name them, and you avoid them.
| Mistake | Why It’s Dangerous | The Right Move |
|---|---|---|
| Drop-starting the saw | No control if kickback happens during start; chain can hit your leg | Ground-start with the brake engaged every time |
| Cutting above shoulder height | Kickback launches the saw into your face and neck | Use a pole saw or hire a climber for high cuts |
| Using one hand on the saw | No leverage to resist kickback; one hand slips off instantly | Two hands at all times — left on front, right on rear |
| Cutting with the upper bar tip | Direct kickback zone; the saw flips upward at head height | Cut only with the lower two-thirds of the bar |
| Fueling a hot or running saw | Gasoline vapors ignite from engine heat | Let the saw cool fully; fuel at least 10 feet away |
| Letting the chain touch dirt or rock | Dulls the chain instantly and can grab, causing kickback | Clear debris before cutting; keep the bar off the ground |
| Cutting a stuck tree loose by felling adjacent trees | Unpredictable fall direction; the hung tree can fall backward on you | Call a professional with a winch or tracked machine |
Rules for Fueling and Transport
Gasoline and chainsaws are a high-risk combination, and the rules around fueling are simple and absolute. Shut the engine off and let the saw cool completely before touching the fuel cap. Move at least 10 feet away from the worksite — and any open flame, pilot light, or hot muffler — before you pour. Use only OSHA or DOT approved safety cans; never refuel from a regular gas can with a loose spout. Use a funnel or flexible hose to avoid spills, and wipe any drips off the saw before restarting. No smoking within the full fueling zone.
When you’re moving with the saw — between cuts, walking to another tree, or packing up — shut the engine off and engage the chain brake. Carry it by the front handle with the muffler pointing away from your body and the bar pointing behind you. Never carry a running saw slung over your shoulder.
Quick Reference: The Full Safety Sequence
Print this sequence and run through it before every session. Doing each step in the same order every time builds the muscle memory that prevents the one bad second.
- Don every piece of PPE — nothing skipped
- Inspect chain tension, sharpness, oil level, and controls
- Clear the cutting zone of trip hazards, debris, and hidden metal
- Ground-start with chain brake engaged, choke on, saw pinned
- Stand to the side of the cut plane, two-handed grip, thumbs wrapped
- Cut at waist level using the lower bar, full throttle, rocking motion
- Engage brake or shut off before each move of more than a few steps
- Cool saw before fueling, 10 feet minimum from any ignition source
FAQs
Do I really need special chaps or can I use thick jeans?
Standard jeans offer no protection against a moving chain. Chainsaw chaps contain Kevlar fibers that jam the chain and stop it instantly on contact. A kickback at leg height cuts through denim in a fraction of a second, making chaps a necessary piece of safety gear, not a luxury.
What is the safest way to cut a fallen tree that is under tension?
Stand on the opposite side of the trunk from where the tension is pulling. Make a shallow cut on the compression side first — about a third of the way through — then finish from the tension side. If the branch is bent like a bow, the spring force can throw the saw back across your body once cut free.
How often should I sharpen the saw chain?
Sharpen whenever the saw produces fine dust instead of chips, or when you have to push harder to keep the saw cutting. A dull chain creates excess heat, burns the bar oil, and increases kickback risk because the chain catches rather than slicing cleanly through wood.
Should I wear work gloves or chainsaw-specific gloves?
Regular work gloves improve grip but won’t stop a moving chain. Chainsaw-specific gloves have cut-resistant layers on the back of the left hand — the area most exposed during kickback. For general homeowner cutting, any snug-fitting safety glove beats bare hands, but dedicated chainsaw gloves add real protection.
Can I fill the bar oil with used motor oil to save money?
No. Used motor oil lacks the tackiness that keeps bar oil clinging to the chain at high speed, and it contains contaminants that clog the oiler port. Bar oil is cheap relative to the cost of replacing a seized bar and chain, and it’s the only lubricant the manufacturer designs the oiler to handle consistently.
