1Inspect the chainsaw for loose bolts or screws, before and after each use.
2Regularly check the air and fuel filters.
The air filter has the important job of preventing dirt and debris from getting into the engine. If it’s exceptionally dirty or torn, replace it. Air filters should be replaced every 100 hours of use or every three months. If there are tears or clogs in the fuel filter screen, replace it. Enter your chainsaw’s model number to find the fuel filterfilters designed specifically for your model.
3Regularly check the chain.
Check the chain for dullness and damage such as bent chain links. If you find any damage, replace the chain before using it again. Chainsaws are designed to smoothly cut wood; if it requires some elbow grease from you to penetrate the wood, the chain needs to be sharpened. Chainsaws can be professionally sharpened or you can buy a kit to do it yourself, but it’s often less expensive and easier to simply replace the chain.
4Use the proper gasoline and oil mixture in two-cycle, gas-powered models.
Make sure that you always follow the owner’s manual’s instructions for proper gasoline and oil mixture. Failing to use the right mixture can result in serious problems. Insufficient lubrication may cause engine failure. Too much oil can clog the spark arrester inside of the muffler.
5Regularly use a degreaser.
Spray on the degreaser
only when the engine is completely cool. Let the degreaser sit for 10-15 minutes before wiping away with a clean cloth. Then use a hose to rinse off the unit. Be sure to allow the chainsaw to dry completely before using it.
6Clean the air filter.
Clean the chainsaw’s air filter every five hours of use and replace it every 100 hours or three months, whichever comes first. If there are any tears or holes, replace it before using the chainsaw again.
7Regularly lubricate the bar and chain.
Use bar-and-chain oil to lubricate the bar. Conventional motor oil does not work well for this purpose because it doesn’t have enough viscosity; the rotating chain will expel the oil too quickly.
8Replace the spark arrestor.
Every 25 hours of use or once a season, replace the spark arrestor located within the engine’s muffler. Since spark arrestors are made of fiberglass, they’re not designed to be cleaned and reused.
9Clean the battery terminals in battery-powered models.
If you have a battery-powered chainsaw, follow the owner’s manual for instructions on cleaning the battery terminals and regularly charge the battery.
10Prep it for off-season storage.
Before storing your chainsaw for the off season, thoroughly inspect it for damage and replace parts as needed. Use a fuel stabilizer with fresh fuel to prevent clogging the carburetor.
