Servicing your Chainsaw

 by: Keith Kingston

Chainsaws provide many years of service for very little upkeep. Taking the time to service your chainsaw will help ensure that your equipment will not let you down. For safety reasons, make sure you only service your chainsaw when it is fully cooled, with the spark plug disconnected. If you are working with an electric chainsaw make sure it is unplugged first of all. You should also wear gloves and protection for your eyes.

For safe and effective operation having correct chain tension is necessary. As the chain wears, significant stretching will occur. After five to ten cuts a new chain may need to be readjusted. Separation from the guide bar or binding into the wood can occur if the chain is loose. Premature chain and guide bar wear will be caused by a tight chain. A chain that is well adjusted will move easily and smoothly when pulled by a gloved hand. Binding or sagging by the chain should not occur. The chain tension should be checked and adjusted if needed before every use.

A manual or automatic chain oiling system is used in most chainsaws. Friction and heat builds between the chain and guide bar without oil. The oil also helps the individual links in the chain operate smoothly at high speeds. Check the oiling system prior to every use.

Tighten all of the screws and fasteners. This process should be done before every use. Before using your chainsaw each time you need to inspect the fuel system.

After every 10 hours of use you need to clean or replace the air filter. Byreplacing the air filter on a regular basis your chainsaw will be able to run cooler and use less fuel.

The sprocket tip should be lubricated after every 10 hours of use. You will know that lubrication is complete when a small amount of grease appears at the edge of the guide bar near the sprocket.

For every 10 hours of use the guide bar should be turned. Flip the guide bar over to promote an even wear pattern on the bottom and top of the bar. Inspect the spark plug after every 10 hours of use and cleaned or replaced as necessary.

For every 10 hours of use the spark arrester screen should be inspected and cleaned and replaced when necessary. The spark arrester screen prevents sparks from leaving the exhaust port and hurting the operator or falling on flammable materials.

The fuel filter should be replaced after every 20 hours of use. Poor performance can result if the filter becomes clogged.

To ensure the maximum performance perform the following procedures as needed to prolong the life of your chainsaw. Take your chainsaw to an authorized dealer if the carburetor needs adjustment. The chain blades should be sharpened periodically as they become dull.
