WARNING! Kickback can cause severe injury. Never operate with one hand. Keep chain sharp and properly tensioned.

Assembly & Preparation

Unpack and inspect contents. Assemble on clean, flat surface.

1. Attach Guide Bar & Chain: Place bar on mounting studs. Fit chain with drive links in bar groove and cutting teeth facing forward on top. Adjust tension.

Controls and Components

Components: Muffler, Spark plug, Air filter cover, Fuel cap, Oil cap, Chain tensioner, Chain catcher, Right-hand guard.

Operation: Throttle lockout must be depressed before throttle trigger can be engaged. Chain brake is engaged by pushing front handle forward or by inertia. Decompression valve reduces cylinder pressure for easier starting.

Starting & Operation

Cold Start Procedure:

1. Engage chain brake. Place on flat ground.
2. Press decompression valve (if equipped).
3. Set choke control to full choke position.
4. Press primer bulb 6-8 times (if equipped).
5. Pull starter handle until engine fires (1-3 pulls).
6. Move choke to half-throttle position.
7. Pull starter handle until engine starts.
8. Blip throttle to disengage fast idle. Release chain brake.

Warm Start: Do not use choke. Follow steps 1, 7-8.

Cutting Techniques: Use lower quadrant of bar for cutting. Let saw do the work. Avoid pushing tip into wood.

Maintenance Schedule

Note: Maintenance intervals depend on usage intensity. Always disconnect spark plug wire before maintenance.

Chain Sharpening & Tensioning

Proper chain maintenance is critical for safety and performance.

1. Tensioning: Loosen bar nuts. Adjust tensioning screw until chain fits snugly against bar but can be pulled around by hand. Retighten bar nuts.
2. Sharpening: Use round file matching chain pitch (typically 5/32" for 3/8" chain). File each cutter at 30° angle. Maintain equal length on all cutters. File depth gauges with flat file.
3. Lubrication: Ensure oiler is working. Chain should throw oil during operation.

CAUTION! Always wear gloves when handling chain. A dull chain increases kickback risk.

Storage Guidelines

For storage over 30 days:

1. Drain fuel tank and run engine until it stops.
2. Remove spark plug and add 1 teaspoon of engine oil through spark plug hole. Pull starter 2-3 times to distribute oil. Reinstall plug.
3. Clean entire saw thoroughly.
4. Remove chain, clean, and soak in oil. Store separately.
5. Store in dry, cool place away from ignition sources.

CAUTION! Never store with fuel in tank for extended periods. Fuel deteriorates and can damage engine.
