Operation
STARTING THE ENGINE
Refer to Figure 4.
1. Turn the fuel valve (B) to the ON position.
2. Insert the engine key (F) into the engine key slot.
3. Move the throttle lever (E) to the FAST position.
4. Fully close the choke (G) if engine is cold (a warm
engine may not require choking).
5. Push the primer button (D) two times if engine is cold
(a warm engine may not require priming).
6. Pull starter handle (C) rapidly, or push starter button
if equipped with the electric start. Do not allow the
starter handle to snap back—let the starter rope
rewind slowly—while keeping a firm grip on the
starter handle.
7. As the engine starts and begins to operate evenly,
open the choke (G) slowly and set the throttle lever to
SLOW. If the engine falters, turn the choke knob
clockwise until the engine runs smoothly, and let it
run briefly before returning the choke to the OPEN
position.
NOTE: Allow the engine to warm up at SLOW throttle for
a few minutes before operating the snowthrower at full
speed. The engine will not develop full power until it
reaches operating temperature.
