Safety Information

Read and understand all instructions before use. Always wear appropriate PPE.

1. Personal Protective Equipment (PPE): Wear safety glasses, hearing protection, gloves, chainsaw chaps, and sturdy boots.
2. Clear Work Area: Ensure no bystanders, pets, or obstacles within 15 feet.
3. Secure Workpiece: Never hold with one hand; use sawhorses or clamps for small material.
4. Kickback Awareness: Be aware of the kickback zone (upper quadrant of bar tip).

WARNING! Chainsaws are dangerous tools. Failure to follow safety instructions can result in serious injury or death. Keep hands away from chain. Always engage chain brake when not cutting.

Assembly & Preparation

Unpack and inspect all parts. Assemble on a clean, flat surface.

1. Attach Guide Bar & Chain: Place bar on mounting studs, loop chain over sprocket and bar with cutters facing forward on top, adjust tension.

Starting & Operating

Starting Procedure (Cold Engine):

1. Place on flat, clear ground. Engage chain brake.
2. Press primer bulb 5-10 times.
3. Set master control to CHOKE position.
4. Hold rear handle with right foot, pull starter cord sharply until engine 'pops'.
5. Move control to RUN position.
6. Pull starter cord again to start. Allow 30-second warm-up.

Cutting Technique: Use full throttle when cutting. Let chain do the work; do not force. Be aware of pinch points, especially when cutting logs under tension.

Chain & Bar Maintenance

Regular maintenance ensures performance and safety.

1. Chain Tension: Check frequently when cold. Chain should snap back when pulled from bar but not sag. Adjust via side tension screw.
2. Sharpening: Use round file and guide. Maintain correct filing angle (typically 30°). File all cutters evenly.
3. Bar Maintenance: Clean bar groove regularly. Flip bar weekly for even wear. Check for burrs and file smooth.
4. Sprocket: Inspect for wear; replace if teeth are hooked or worn.

WARNING! Always wear heavy gloves when handling chain. Ensure engine is off and spark plug wire is disconnected.

Fuel & Lubrication

Fuel Mix: Use fresh, unleaded gasoline (max 10% ethanol) mixed with a high-quality 2-cycle engine oil designed for air-cooled engines. Ratio: 40:1 (3.2 oz oil per 1 gallon gas).

Chain Oil: Use proper bar and chain oil for all temperatures. Do not use waste oil. Check oil level before each use.

Air Filter: Clean regularly with soapy water, dry, and re-oil (if foam type). Replace if damaged.

Storage

For storage longer than 30 days:

1. Drain all fuel from tank and carburetor. Run engine until it stops.
2. Remove spark plug, add 1 teaspoon of engine oil into cylinder, pull starter slowly 2-3 times, reinstall plug.
3. Clean entire saw, especially cooling fins and air filter.
4. Loosen chain tension. Store in a dry, secure place.

CAUTION! Storing with fuel in the system can cause gum deposits and carburetor damage.
