Safety Information

Read all instructions before use. Always wear appropriate PPE.

1. Personal Protective Equipment (PPE): Always wear safety glasses, hearing protection, gloves, chainsaw chaps/pants, and steel-toe boots.
2. Work Area Safety: Keep bystanders and pets at least 15 feet away. Ensure secure footing.
3. Kickback Zone: Be aware of the upper quadrant of the bar tip. Do not let it contact objects.
4. Chain Brake Test: Test before each use by engaging brake with the saw off.

WARNING! Failure to follow safety instructions can result in serious injury or death. Never operate a chainsaw while fatigued or under the influence.

Assembly & Preparation

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

1. Attach Guide Bar & Chain: Loosen bar nuts. Place bar over studs. Fit chain around sprocket and bar, ensuring cutting teeth face forward on top. Tighten nuts finger-tight.
2. Tension Chain: Use side-access tensioner screw to adjust until chain snaps back when pulled from bar. Tighten bar nuts securely.
3. Fill Fluids: Use fresh 50:1 gasoline/oil mix for fuel. Use high-quality bar and chain oil. Do not mix.
4. Check Controls: Ensure throttle trigger, throttle lockout, and chain brake function smoothly.

CAUTION! The chain is extremely sharp. Always wear heavy gloves during assembly.

Starting & Operating

Cold Start Procedure:

1. Place saw on firm, flat ground. Engage chain brake.
2. Press decompression valve (if equipped).
3. Set Master Control Lever to CHOKE position.
4. Pump primer bulb 5-10 times (if equipped).
5. Pull starter rope sharply until engine 'pops'.
6. Move lever to RUN position.
7. Pull starter rope again to start. Let idle for 30 seconds.

Operating: Disengage chain brake. Squeeze throttle lockout and trigger to increase RPM. Begin cut with the lower part of the bar. Let the saw do the work; do not force it.

WARNING! Always hold saw firmly with both hands. Never operate above shoulder height.

Chain & Bar Maintenance

Regular maintenance ensures optimal performance and safety.

1. Chain Sharpening: Use correct round file size (.325" uses a 4.0mm or 5/32" file). Maintain 30° top plate cutting angle and 10° file tilt. Sharpen when saw produces fine dust instead of chips.
2. Chain Tension: Check frequently when hot and cold. Chain should be snug but pull freely from bar. Retighten bar nuts after adjustment.
3. Bar Maintenance: Flip bar weekly for even wear. Clean bar groove and oil holes. Dress bar rails with a flat file if burred.
4. Oiling System: Check oil flow by pointing bar tip at a light surface and running at high idle. Adjust oiler screw if necessary.

CAUTION! Disconnect spark plug wire before performing any maintenance involving the chain or bar.

Storage & Winterization

For storage longer than 30 days:

1. Drain all fuel from tank and run carburetor dry.
2. Remove spark plug, add 1 tsp of 2-stroke oil into cylinder, pull starter slowly 2-3 times, reinstall plug.
3. Clean entire saw, especially air filter and cooling fins.
4. Remove chain, clean, and soak in oil. Store bar coated in oil.
5. Store in a dry, cool place, protected from dust.

Tip: Use fuel stabilizer if you cannot drain the fuel system completely.
