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.
