What Chainsaw Maintenance Should Be Done Seasonally?

April 6, 2026

Quick Answer

Maintain your chainsaw by checking the air filter and cleaning or replacing it every 25 hours of use, sharpening the chain every 10 hours, and checking the oil level and chain tension every 5 hours.

Pre-Season Preparation

Before the firewood season begins, inspect your chainsaw for any damage or wear. Check the air filter and clean or replace it if necessary. Sharpen the chain to a 1/16 inch (1.5 mm) to 1/32 inch (0.75 mm) kerf to ensure efficient cutting. Apply a coat of rust-inhibiting oil to the chain to protect it from corrosion. Check the oil level and top it off if necessary.

Mid-Season Maintenance

As you reach the mid-point of the firewood season, inspect your chainsaw for wear and tear. Clean or replace the air filter every 25 hours of use to maintain proper engine performance. Sharpen the chain every 10 hours to prevent dulling and reduce the risk of kickback. Check the chain tension and adjust it as needed to maintain proper cutting performance.

Post-Season Storage

After the firewood season ends, store your chainsaw properly to prevent damage and extend its lifespan. Drain the oil and fuel from the chainsaw and store it in a dry, well-ventilated area. Clean the air filter and store it in a plastic bag to keep it dust-free. Apply a coat of rust-inhibiting oil to the chain and store it in a dry area to prevent corrosion. Regular maintenance will ensure your chainsaw is ready for the next firewood season.
