Operation

STARTING THE ENGINE

1. Turn the fuel valve (B, Figure 6) to the ON position.

2. Insert the Engine Key (F, Figure 6) into the Engine

Key slot and push fully in to the RUN position.

3. Move the Throttle Lever (E, Figure 6) fully up to the

FAST position.

4. Turn the Choke Knob (G, Figure 6) fully clockwise if

engine is cold. (Do not choke a warm engine.)

5. Push the Primer Button (D, Figure 6) two times if

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

6. Pull Starter Handle (C, Figure 6) 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,

turn the Choke Knob (G, Figure 6) slowly counter-
clockwise to the OFF position, 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 OFF
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.
