4. Operating Instructions

4.1 Starting the Engine

1. Ensure the engine is on a level surface.
2. Open the fuel valve (if applicable).
3. Move the choke lever to the "CHOKE" position (cold engine start). For a warm engine, the choke may not be necessary.
4. Move the throttle lever to the "FAST" position.
5. Turn the engine switch to the "ON" position.
6. Grasp the recoil starter handle firmly and pull slowly until resistance is felt, then pull quickly and smoothly to start the engine. Repeat if necessary.
7. Once the engine starts, gradually move the choke lever to the "RUN" position as the engine warms up.

4.2 Stopping the Engine
