Safety Notice

General Safety Precautions

Read manual, no unsupervised children, check screws. Loctite 242 Blue recommended.

Engine Mounting

Mounting and Vibration Damping

Mount in vibration-absorbing environment; avoid hard bench mounting for break-in.

Propeller Safety Guidelines

Stand clear of propeller, never be in front, wear protective eyewear, avoid loose clothing.

Engine Adjustment

Carburetor Mixture Settings

Initial settings are average; adjust for location/altitude. Use starting points for needles.

Avoid overly rich mixture. Check spark plug for slight yellow color after break-in.

Low RPM Running Caution
