How to Properly Maintain a Chainsaw

A chainsaw is a dangerous tool that requires careful handling. To ensure your chainsaw operates effectively and lasts a long time, proper usage, maintenance, and care are essential. So, how do you properly maintain a chainsaw?

Fuel

Chainsaws use a mixture of gasoline and oil in the proportions specified in the tool’s manual. Be sure to use oil specifically designed for two-stroke engines with air cooling. Mix the components in a separate container. The resulting mixture should not be stored for more than a month, even if the manual states a longer shelf life. This is due to the quality of petroleum products. In other words, only use fuel in the tank that has been prepared within the past month.

Sawing System

Lubricating the Chain and Guide Bar
First, check the oil level in the chain lubrication tank. If the level is sufficient, test the oil flow to the chain. After starting the engine, place the “nose” of the guide bar near a surface and rev the engine to its maximum speed. If, after a few seconds, no oil splashes are visible, stop the chainsaw immediately and clean the oil channels with a brush or compressed air to remove sawdust and debris. After cleaning, check and adjust the oil flow as necessary. Without proper lubrication, the chain, guide bar, and drive sprockets can overheat and become damaged, which will not be covered under warranty.

Adjusting Chain Tension
Over time, the chain may loosen to the point of slipping off the guide bar. Use the adjustment screw, located on the side of the chainsaw (accessible through the clutch cover), to tighten the chain. Turn the screw clockwise to increase the tension.

Dulling of the Cutting Links
The chain’s cutting edges can dull quickly, especially if it hits nails, stones, or soil. When cutting old boards, inspect them for nails and remove any before sawing. It’s best to work in a designated area free of materials that could dull the chain. For sharpening, you can either invest in a specialized sharpening machine or seek professional assistance.

Additionally, to ensure even wear, periodically flip the guide bar.

Air Filter

The air filter should be cleaned of sawdust after each use. If heavily soiled, wash it in soapy water and allow it to dry. A dirty air filter reduces airflow to the carburetor, causing the engine to run inconsistently and lose power.

How to Properly Maintain a Chainsaw: General Tips

Chainsaw maintenance should start with cleaning. After each use, clean the tool of sawdust, paying special attention to the lubrication holes on the guide bar and housing, the starter’s air vents, the engine cylinder’s cooling fins, and the chain brake’s mechanical parts. Delaying this task for weeks will make it much harder to clean later.

To keep the tool in good condition, inspect the spark plug, high-voltage wire, and fuel filter monthly. Annually, adjust the carburetor.

If damage occurs, it’s best to use the warranty and entrust repairs to professional service center technicians. This will save you time, effort, and stress while extending the life of your chainsaw.
