Operation

STARTING THE ENGINE

1. Turn the fuel valve (B, Figures 8 & 9) to the ON posi-

tion.

2. Insert the Engine Key (F, Figures 8 & 9) into the

Engine Key slot and push fully in to the RUN position.

3. Move the Throttle Lever (E, Figures 8 & 9) fully up to

the FAST position.

4. Fully close the Choke (G, Figures 8 & 9) if engine is

cold. (Do not choke a warm engine.)

5. Push the Primer Button (D, Figures 8 & 9) two times

if engine is cold. (Do not prime a warm engine.)

6. Pull Starter Handle (C, Figures 8 & 9) 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, Figures 8 & 9) slowly and set the
Throttle Lever to SLOW. If the engine falters, turn the
Choke Knob clockwise until the engine runs smooth-
ly, 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.
