SECTION 6:  CONTROLS

Figure 10  

(Refer to Figure 10 for illustration of controls 
described below.) 

SHIFT LEVER 

The shift lever is located in the center of the handle 
panel. The shift lever may be moved into one of 
eight positions. Use the shift lever to determine 
ground speed.
Forward—one of six speeds. Position number one 
(1) is the slowest. Position number six (6) is the 
fastest.
Reverse—two reverse (R) speeds. “R” closest to the 
operator (all the way back) is the faster of the two.

AUGER DRIVE 

The auger drive clutch is located on the left handle. 
Squeeze the clutch grip to engage the augers. 
Release to stop the snow throwing action. (Traction 
drive clutch must also be released.)

TRIGGER LEVER

The left and right turn triggers are located on the 
underside of the handles and are used to assist in 

steering your snowthrower. Squeeze the right turn 
trigger when turning right and the left trigger when 
turning left.

TRACTION DRIVE/AUGER CLUTCH 
LOCK

The traction drive clutch is located on the right 
handle. Squeeze the traction drive clutch to engage 
the wheel drive. Release to stop.
This same lever also locks the auger clutch so you 
can turn the chute crank without interrupting the 
snow throwing process. If the auger drive clutch is 
engaged with the traction drive clutch engaged, the 
operator can release the auger drive clutch (on the 
left handle) and the augers will remain engaged. 
Release the traction drive clutch to stop both the 
augers and wheel drive (auger drive clutch must also 
be released).

CHUTE CRANK 

The chute crank is located on left hand side of the 
snow thrower.
To change the direction in which snow is thrown, 
turn chute crank as follows:

1.

Crank clockwise to discharge to the left.

2.

Crank counterclockwise to discharge to the right.

CHUTE TILT CONTROL 

The distance snow is thrown can be adjusted by 
adjusting the angle of the chute assembly. Move the 
chute tilt control forward to decrease the distance, 
toward the rear to increase.

HEADLIGHT

The headlight is on whenever the engine is running.

THROTTLE CONTROL 

The throttle control is located on the engine. It 
regulates the speed of the engine. When blowing 
snow, always run engine with throttle in the fast 
position. 

SAFETY IGNITION SWITCH 

The ignition key switch must be inserted completely 
in the switch before the unit will start. Do not attempt 
to turn the key.

FUEL SHUT-OFF VALVE

The fuel shut-off valve, located under the fuel tank, 
controls fuel flow from tank. Make sure it is not 
turned off before starting the engine.
