2. Weekly: Check bar for wear and straightness. Clean oil tank vent.
3. Monthly: Inspect power cord for damage. Check all nuts and bolts for tightness.
4. As Needed: Sharpen chain when cuts become slow or produce fine dust.

CAUTION! Use only Husqvarna-approved replacement parts. Do not use damaged components.

Chain & Bar Care

Proper chain and bar maintenance is critical for performance.

• Sharpening: Use round file matching chain pitch (5/32" for 3/8" LP). Maintain 30° filing angle. File all cutters to equal length.
• Depth Gauges: File down after several sharpenings using depth gauge tool.
• Bar Maintenance: Clean bar groove regularly. Flip bar weekly to ensure even wear.
• Lubrication: Always use recommended chain oil. Check oil flow by running saw over light-colored surface; look for oil line.

Storage Guidelines

Store in a dry, secure place out of reach of children.

1. Clean thoroughly: Remove sawdust and resin from all surfaces.
2. Protect chain & bar: Apply a light coat of oil to prevent rust.
3. Store cord: Loosely coil; avoid sharp bends.
4. Long-term storage: Empty oil tank to prevent sludge buildup.

CAUTION! Do not store with fuel (not applicable for electric model). Keep away from extreme temperatures.
