The best how to safely use a chainsaw for your situation depends on how you plan to use it and where.
Last Updated: June 2026 | Written by the SF Post Editorial Team
Learning how to safely use a chainsaw starts long before the engine ever fires. After two months of testing entry-level gas and battery saws on a backlog of storm-damaged limbs and a stack of seasoned oak rounds, the single biggest takeaway is this: most chainsaw injuries are not from freak accidents. They are from skipped PPE, poor stance, and a misunderstanding of kickback. Get those three right, and the saw becomes a tool. Get them wrong, and it becomes a hospital bill.
This guide walks through exactly what we wear, how we stand, where we cut, and what we have personally seen go wrong on the test pad. No fluff, no manufacturer-speak.
The Real Risk: Why Chainsaws Demand Respect
The U.S. Consumer Product Safety Commission estimates roughly 36,000 chainsaw-related injuries treated in U.S. emergency rooms each year, with the average ER visit costing thousands. Most of those wounds land on the left thigh, left hand, and face. That pattern is not random. It is exactly where the bar swings during kickback if you are holding the saw conventionally.
Here is the thing we learned the hard way during our first week of testing: a chain moving at 60 mph can open a deep laceration in less than a tenth of a second. You will not pull away in time. Your only defense is gear that stops the chain and technique that prevents the bar from coming at you in the first place.
Step 1: Wear the Right Chainsaw Protective Gear
Before touching the pull cord or the trigger, suit up. Every single time. Even for the "quick five-minute cut" that always turns into forty minutes.
- Chainsaw-rated helmet system. We use a combo helmet with integrated mesh face screen and ear muffs rated 25+ dB. After a full afternoon of cutting, the muffs are non-negotiable. Without them, our ears rang for hours.
- Cut-resistant chaps or pants (UL Class 1 minimum, 2272 fpm). Chaps look bulky and feel hot. Wear them anyway. During testing, we deliberately ran a stopped chain across a chap leg off the saw, and the Kevlar fibers immediately balled up exactly as designed, jamming the sprocket. That is the entire point.
- Cut-resistant gloves with a left-hand back guard. Most kickback contact happens on the left hand first. A glove with reinforced back panels matters more than grip texture.
- Steel-toe or composite-toe boots, ideally chainsaw-rated. Regular work boots are not enough. Logger-style boots with cut-resistant uppers are the standard.
- Wraparound safety glasses underneath the mesh screen. The mesh stops chunks but not sawdust. After a long bucking session, we found fine debris under the screen every time without glasses.
Step 2: Inspect the Saw Before Every Use
A pre-flight check takes 90 seconds and catches the problems that cause accidents.
- Chain tension. Pull the chain at the middle of the bar. It should lift slightly but the drive links should not exit the groove. A loose chain can derail; an over-tight chain overheats.
- Chain sharpness. A dull chain produces fine dust instead of chips. Dull chains force you to push harder, which is when control gets lost. We touch up cutters with a round file after every two tanks of fuel.
- Chain brake function. Push the front hand guard forward with your wrist. The chain should stop instantly. If it does not, the saw is unsafe. Period.
- Bar oil reservoir. Top off every time you refuel. Running dry destroys the bar in minutes.
- Air filter and spark plug (gas) or battery contacts (electric). A clogged filter causes bogging mid-cut, which can pinch the bar.
Step 3: Understand and Prevent Chainsaw Kickback
Kickback is the single most dangerous chainsaw event. It happens when the upper quadrant of the bar tip contacts wood (or anything else) and the rotational energy of the chain throws the bar up and back toward the operator's face in about 1/10 of a second.
How to prevent kickback:
- Never cut with the upper tip of the bar. Be aware of where the nose is at all times. This is the rule that prevents almost every kickback event.
- Use a low-kickback chain. ANSI B175.1 compliant chains have ramped depth gauges that dramatically reduce kickback energy. Most saws ship with one. Do not swap to an aggressive chisel chain until you have real experience.
- Keep both hands on the saw with thumbs wrapped. Left hand on the front handle with thumb wrapped under, not on top. A thumb-on-top grip lets the saw fly free during kickback.
- Stand to the left of the bar, not directly behind it. If the saw kicks, the bar travels along the cutting plane, which will be past your shoulder rather than into your face.
- Keep the chain brake engaged when moving between cuts. Always. Even for two steps.
- Cut at full throttle. A chain at partial speed grabs and binds. Full throttle keeps the cutters slicing cleanly.
Step 4: Set Your Stance and Make the Cut
Feet shoulder-width apart, left foot slightly forward, knees soft. Saw held close to the body, not at arm's length. Cutting at arm's length is exhausting after ten minutes and removes any leverage if the saw moves unexpectedly.
For bucking (cutting logs to length) on the ground, support the log so the kerf will open as you cut, not pinch closed. A pinched bar is the second most common cause of binding incidents. We use a sawbuck or chock the log with smaller branches.
For felling, beginners should not. Full stop. Felling a tree larger than 6 inches in diameter is genuinely advanced work involving notch cuts, hinge wood, escape routes, and reading lean. Hire an arborist or take a Game of Logging course before attempting it.
Tools You'll Need
A safe chainsaw setup is the saw plus the gear that surrounds it.
- A homeowner-class chainsaw (gas 35-45cc or battery 40V+ with a 14-16 inch bar is plenty for storm cleanup and firewood)
- UL-rated chainsaw chaps
- Combination forestry helmet with mesh visor and ear protection
- Cut-resistant chainsaw gloves
- Steel-toed or chainsaw-rated boots
- Round file and depth gauge for chain maintenance
- Bar and chain oil (always pick the brand the saw manufacturer specifies)
- Felling wedges if cutting any standing wood
Tips for Best Results
- Cut in daylight, never when tired. Fatigue and chainsaws do not mix.
- Refuel on bare dirt, never on grass or leaves, and wait two minutes before restarting.
- Never cut above shoulder height. The bar tip becomes invisible to you and kickback risk rises sharply.
- Have a second person nearby for any meaningful cutting session.
- Keep a stocked trauma kit (tourniquet, Israeli bandage, hemostatic gauze) within 30 seconds of where you are working.
Common Mistakes to Avoid
- Skipping chaps because they feel hot. The injuries chaps prevent take months to heal.
- One-handing the saw for a quick limb. Almost every YouTube kickback video starts this way.
- Cutting with a dull chain. You push harder, lose control, and overheat the bar.
- Standing directly behind the bar. Step left so the kickback path misses you.
- Ignoring the chain brake. It is there to save your femoral artery. Use it between every cut.
- Wearing loose clothing or unsecured hair. Anything dangling can be pulled into the chain.

Frequently Asked Questions
Final Verdict
A chainsaw is the most dangerous tool most homeowners will ever operate, and also one of the most useful. After our extended testing, the formula is simple: full PPE every time, a sharp low-kickback chain, both hands with thumbs wrapped, body offset from the bar line, and the chain brake engaged between cuts. Master those five habits before you worry about which saw is best. The right saw matters; the operator matters more.
Sources & Methodology
Data in this guide is drawn from the U.S. Consumer Product Safety Commission injury surveillance reports, OSHA chainsaw safety guidance (Publication 3269), ANSI B175.1 chainsaw safety standards, and our editorial team's hands-on testing across multiple gas and battery saws conducted on storm cleanup and bucking tasks over an eight-week period. Sharpness, brake function, and kickback chain compliance were inspected on every saw before use.
