Starting & Operation

Cold Start Procedure:

1. Engage chain brake by pushing front hand guard forward.
2. Set Master Control Lever to CHOKE (⏫).
3. Press decompression valve (if equipped).
4. Place saw on firm ground, hold rear handle with right foot.
5. Pull starter cord sharply until engine 'fires' (usually 3-5 pulls).
6. Move Master Control Lever to RUN (I).
7. Pull starter cord again until engine starts.
8. Blip throttle to disengage fast idle. Release chain brake before cutting.

Warm Start: Set lever to RUN (I) and pull starter.

Cutting Technique: Use full throttle during cut. Let chain do the work; avoid forcing. Be aware of pinch points, binding, and kickback.

Maintenance Schedule

Note: Always disconnect spark plug wire before performing maintenance.

Chain Sharpening & Tensioning

Sharpening: Use round file matching chain pitch (typically 5.5 mm). Maintain 30° cutting angle and 10° top plate angle. File all cutters to equal length.

Tensioning: Chain should be snug against guide bar but pullable by hand (with gloves). Re-tension when chain sags away from bar. Always tension with saw cold.

Lubrication: Ensure automatic oiler is working. Check oil flow by pointing bar tip at a light surface and running at full throttle; a line of oil should appear.

Storage Guidelines

For storage over 30 days:

1. Drain fuel tank and run carburetor dry.
2. Remove chain, clean, and soak in oil.
3. Clean entire saw, especially cooling fins and air filter.
4. Store in a dry, locked place, out of reach of children.

CAUTION! Never store with fuel in tank for extended periods. Old fuel can damage carburetor.
