1. Fuel mixture: Mix gasoline with 2-stroke oil at 50:1 ratio (check manual).
2. Fill fuel tank: Use fresh fuel mixture, avoid overfilling.
3. Prime engine: Press primer bulb 5-10 times until fuel visible.
4. Set choke: Move to cold start position for initial start.
5. Test chain brake: Engage and disengage to ensure proper function.

CAUTION! Perform setup in well-ventilated area away from sparks or flames.
