A chainsaw is a useful, powerful tool. Knowing the proper method for operating a chainsaw doesn't just help you work more efficiently, it helps you work more safely. Read the user’s manual before operating your saw, so you know how it works, are familiar with all its parts and controls and are aware of safety procedures.
If the chain isn’t new, it’s a good idea to sharpen it before beginning. Cutting is both easier and safer when the chain is sharp. Also check the tension of the chain and adjust it if needed. Don’t forget that you'll need to retension a new chain after operating the saw for a short period. Your owner's manual should give you instructions for sharpening and tensioning the chain on your specific saw. You can also take a look at Chainsaw Maintenance for tips on maintaining the chain and other parts of the saw.
Turn the saw off before performing maintenance, checks or adjustments. In addition, disconnect the spark plug on a gas-powered saw and disconnect an electric saw from the power source.
Wear heavy work gloves when handling a chainsaw chain.
Most gas-powered chainsaws have two-cycle engines, so you'll probably need to mix oil and gasoline. Follow the manufacturer's directions for blending the proper fuel and oil in the correct ratio. Manufacturers may also have recommendations regarding the use of alcohol-blended fuel (such as ethanol). Mix the gasoline and oil in a well-ventilated location. When fueling your saw, use a marked, approved fuel can with overfill protection to avoid unnecessary spillage.
As with fuel, follow the saw manufacturer's instructions for the appropriate chain oil.
Place the chainsaw on a stable surface in a well-ventilated area when filling it with fuel and chain oil. Always fuel at least 10 feet away from the work area. Clean up any spills right away.
Always follow the manufacturer's instructions for use, maintenance and safety, including safety gear. See Chainsaw Safety for more safety information.
Before cranking the saw and starting to cut, protect yourself. ALWAYS wear protective clothing and gear, including:
Corded chainsaws will require a suitable extension cord. Follow the device manufacturer's instructions for selecting compatible extension cords and see Power Cord Safety Tips.
Some hard hats include built-in hearing protection and a face shield.
You can start an electric chainsaw when you're ready to cut by simply activating the trigger. Gas-powered saws require a few more steps. When you’re ready to start a gas-powered chainsaw, place the saw flat on the ground and clear the area around the bar. Starting instructions vary by model and manufacturer, so follow the instructions for your specific saw. Start the saw at least 10 feet away from the fueling area.
Keep others at least 15 feet away when you are using the saw. When felling trees, increase this distance to at least twice the height of the tree you are felling.
If your saw is equipped with a chain brake, you'll need to make sure it works. Place the chainsaw on a stable surface and squeeze the throttle. Activate the chain brake by pushing your left wrist against the front hand guard, without releasing the handle. The chain should stop immediately.
Also check the chain lubrication. Hold the chainsaw above a light surface, such as a stump, and hit the throttle. A line of oil should be visible on the surface after 10 to 20 seconds of running. If your chainsaw has a manual oiling system, you may need to activate it before testing.
If you’re not familiar with using a chainsaw, first get acquainted with it by practicing on a suitable log.
There are some basic rules for using a chainsaw. Hold it firmly by both handles. Your thumbs and fingers should completely wrap around the handles. Make sure you hold your left thumb under the front handle to reduce the force of a possible kickback. Take the saw up to full speed before beginning your cut. If you're using a corded chainsaw, be careful of the cord.
Stand to the side of what you're cutting and make sure you have steady footing.
If you hold the saw close to your body, it won’t feel as heavy. Also, you’ll be more balanced and in better control of the saw. Stand with your feet apart.
Bend Your Knees
Don't work with your back bent. Instead, bend your knees if you’re working at a low level.
Pulling and Pushing Chain
You can saw with both the lower and the upper edge of the bar. When using the lower edge, you’re sawing with a pulling chain, which means that the chain pulls the saw away from you. Using the upper edge of the chain, you’re sawing with a pushing chain, so the chain pushes the saw towards you. There are different potential hazards associated with each cutting method. Make sure you understand the risks of binding, kickback, pushback, pull-in and other hazardous situations. See your manual for safety information and see Chainsaw Safety for additional information.
Never cut with the tip of the saw and be aware that the upper part of the saw tip is the area most prone to causing the chainsaw to kick up and back toward you.
