WARNING! Be aware of kickback. Do not operate with one hand. Keep both hands on handles. Do not cut above shoulder height.

Chain Maintenance

Sharpening: Use correct round file size and guide. File at specified angle (typically 30°). Maintain equal tooth length. Tensioning: Chain should be snug against bar but pull freely. Check tension frequently, especially when new. Adjust when engine is off and cool.

Storage & Care

For long-term storage: 1. Drain all fuel from tank and carburetor. 2. Run engine until it stops to clear fuel lines. 3. Remove chain, clean, and soak in oil. 4. Clean entire saw, especially air filter and cooling fins. 5. Store in a dry, secure place.

CAUTION! Fuel left in the carburetor can degrade and cause starting problems. Always use the storage procedure.
