Fuel & Oil

Use fresh unleaded gasoline (87 octane minimum) mixed with high-quality 2-cycle engine oil. Ratio: 50:1 (check manual). Use bar & chain oil for lubrication reservoir.

1. Mix fuel in approved container, not in saw's tank.
2. Fill fuel tank on level surface, avoid spills.
3. Fill bar oil tank each time you refuel.
4. Use oil recommended for chainsaw bars to reduce wear.

Tip: Never use automotive motor oil, dirty oil, or old gasoline. Stale fuel can cause starting and performance issues.

Starting & Operation

Starting procedure for cold engine:

1. Place saw on clear, level ground. Engage chain brake.
2. Press primer bulb 5-6 times until fuel is visible.
3. Set choke lever to FULL CHOKE position.
4. Pull starter rope sharply until engine "pops" (usually 3-5 pulls).
5. Move choke to HALF CHOKE. Pull starter until engine starts.
6. Allow to warm up 30 seconds. Squeeze throttle to disengage fast idle.
7. Disengage chain brake before cutting.

WARNING! Always hold saw firmly with both hands during operation. Be aware of kickback zone (upper quadrant of bar tip).

Chain Maintenance

Keep chain sharp and properly tensioned. Check tension frequently when new; adjust when chain sags from bar.

1. Stop engine and allow to cool. Engage chain brake.
2. Loosen bar nuts with combination tool.
3. Turn tensioning screw clockwise to tighten until chain fits snug against bar.
4. Pull chain around bar to check for binding; adjust if needed.
5. Tighten bar nuts securely.
6. Sharpen chain regularly with round file and guide. Maintain correct filing angle (typically 30°).

CAUTION! A loose chain can derail; an overtightened chain can damage bar and engine.

Storage

For long-term storage (over 30 days):

1. Drain all fuel from tank and run engine until it stops to clear carburetor.
2. Remove spark plug, add 1 teaspoon of 2-stroke oil into cylinder, pull starter slowly to coat, reinstall plug.
3. Clean entire saw, especially cooling fins and air filter.
4. Remove chain, clean, and soak in oil. Store saw in dry place.

CAUTION! Fuel left in tank can degrade and damage fuel lines and carburetor.
