Maintenance Schedule

Regular maintenance ensures optimal performance and longevity.

Chain Sharpening & Tensioning

Proper chain maintenance is critical for performance and safety.

1. Chain Tensioning: Loosen bar nuts. Adjust tensioning screw until chain snaps back when pulled from bar. Tighten bar nuts while lifting bar tip.
2. Sharpening: Use round file matching chain pitch (5/32" for 0.325 pitch). File at 30° angle. Maintain equal tooth length.
3. Depth Gauges: File depth gauges with flat file to maintain proper height (0.025" below cutter).
4. Inspection: Check for damaged, cracked, or worn cutters. Replace chain if damaged.

CAUTION! Always wear gloves when handling chain. Ensure chain brake is engaged during maintenance.

Storage Instructions

Proper storage prevents fuel system issues and corrosion.

1. Drain fuel tank completely or add fuel stabilizer.
2. Run engine until it stops to clear carburetor of fuel.
3. Remove chain, clean, and soak in oil. Clean guide bar groove.
4. Clean entire saw, especially cooling fins and air filter.
5. Store in dry, cool place, protected from dust and moisture.
6. Cover with breathable cloth; avoid plastic bags that trap moisture.

Tip: For long-term storage, remove spark plug and add teaspoon of oil to cylinder. Pull starter slowly to distribute.
