SECTION 4:  KNOW YOUR SNOW THROWER

WARNING: 

Be familiar with all the controls 

on the snow thrower and their proper 
operation. Know how to stop the machine and 
disengage them quickly.

Auger Control

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 control must 
also be released.) See Figure 6.

Chute Directional Control

The chute directional control is located on left side of 
the snow thrower.

To change the direction in which snow is thrown, turn 
chute directional control as follows:

Crank clockwise to discharge to the left.

Crank counterclockwise to discharge to the right.

Traction Control / Auger Control Lock

The traction control is located on the right handle. 
Squeeze the traction control to engage the wheel drive. 
Release to stop.

This lever also locks the auger control so you can turn
the chute directional control without interrupting the
snow throwing process. If the auger control is engaged
along with the traction control, the operator can
release the auger control (the left handle) and the
augers will remain engaged. Release the traction
control to stop both the augers and wheel drive.

IMPORTANT:

 Always release tractional control before 

changing speeds.

Shift Lever 

The shift lever is located in the center of 
the handle panel and is used to establish 
both ground speed and direction of 
travel. It can be moved into any of eight 
positions. See Figure 6.

Forward

Your snow thrower has six forward (F) 
speeds. Position number one (1) is the 
slowest. Position number six (6) is the 
fastest.

Reverse

Your snow thrower has two reverse (R) 
speeds. R1 is the slower, while R2 is the 
faster of the two.

IMPORTANT:

 Always release tractional control before 

changing speeds.

Chute Tilt Control

The distance snow is thrown can be varied by adjusting 
the pitch of the chute assembly. Move the chute tilt 
control forward to decrease the distance, or toward the 
rear to increase the distance. See Figure 6.

Fuel Shut-off Valve 
(if so equipped)

The fuel shut-off valve, located under fuel tank, controls 
fuel flow from the tank. Always make certain it is in the 
Open (vertical) position before attempting to start the 
engine. See Figure 6.

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.

Ignition Key

The ignition key must be fully inserted in the switch 
before the unit will start. Remove the ignition key when 
snow thrower is not in use.

IMPORTANT:

 Do NOT attempt to turn the key.

Chute Clean-out Tool

WARNING: 

Never use your hand to clear a

clogged discharge chute. Shut off engine and
remain behind handles until all moving parts
have stopped before unclogging.

IMPORTANT:

The chute clean-out tool (see Figure 6) is 

designed to clear a clogged discharge chute. Refer to 

Operating Your Snow Thrower 

on page 10 for detailed 

instructions on how to properly use the chute clean-out 
tool.
