The throttle control is located on the rear 
of the engine. It regulates the speed of the 
engine and will shut off the engine when 
moved into the STOP position.

Pressing the primer bulb forces fuel directly 
into the engine’s carburetor to aid in starting 
a “Cold” engine. NOTE: Do not use the 
primer bulb to restart a warm engine after a 
short shutdown.

Engine oil level can be checked and oil 
added through the oil fill.

Position the skid shoes based on surface conditions. Adjust 
upward for hard-packed snow. Adjust downward when 
operating on gravel or crushed rock surfaces.

Requires the use of a three-prong outdoor extension cord 
and a 120V power source/wall outlet.

This handle is used to manually start the engine.

Pressing the button on the top of the electric starter switch 
engages the engine’s electric starter when plugged into a 
120V power source.

When engaged, the augers rotate and draw snow into the 
auger housing.

Snow drawn into the auger housing is discharged out the 
chute assembly.

Unthread the gas cap to add gasoline to the fuel tank. 

The auger control is located on the left handle. Squeeze 
the control grip against the handle to engage the augers 
and start snow throwing action. Release to stop.

The drive control is located on the right handle. Squeeze 
the control grip against the handle to engage the wheel 
drive. Release the handle to stop. 
The drive control also locks the auger control so that 
you can operate the chute directional control without 
interrupting the snow throwing process. If the auger 
control is engaged simultaneously with the drive control, 
the operator can release the auger control (on the left 
handle) and the augers will remain engaged. Release both 
controls to stop the augers and wheel drive. 
Note: Always release the drive control before changing 
speeds. Failure to do so will result in increased wear on 
your machine’s drive system.
