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.
