Retighten the jam nut to secure the cable when correct adjustment is reached.

Reassemble the frame cover.

NOTE: If you placed plastic film under the gas cap, be certain to remove it before operating the snow thrower.

Drive Wheels

The wheels may be adjusted for two different methods of operation. The adjustment is made by placing the click pins in one of two different holes on the right side of the unit.

One Wheel Driving: Insert the click pin only through the outside hole of the axle (NOT the rim) on the right side of the snow thrower. This position gives power drive to the left wheel only, making the unit easier to maneuver.

Both Wheels Driving: Insert the click pin through the hole in the hub of the rim and the INSIDE hole on the snow thrower’s right axle. This position is good for heavy snow as there is power drive in both wheels.

IMPORTANT: NEVER operate the snow thrower with the click pin inserted through both the RIM and the OUTSIDE HOLE in the axle. Doing so can result in serious damage to the drive system.

Shift Rod

To adjust the shift rod, proceed as follows:

Remove the hairpin clip and flat washer from the shift handle under the handle panel.

Place shift lever in sixth (6) position or fastest forward speed.

Push shift arm assembly down as far as it will go.

Rotate the ferrule up or down on the shift rod as

necessary until the ferrule lines up with the upper hole in the shift lever. See Figure 11.

Insert ferrule from the left side of the snow thrower into the upper hole.

Reinstall the hairpin clip and the washer.

IMPORTANT: Make certain to check for correct adjustment of the shift rod as instructed under Final Adjustments in the Assembly Section, before operating the snow thrower.

Skid Shoe Adjustment

The space between the shave plate and the ground can be adjusted by raising or lowering the skid shoes. Refer to Skid Shoe Adjustment in the Assembly Section.

Auger Control Adjustment

Refer to the information found under Final Adjustments in the Assembly Section to adjust the auger control.

Chute Assembly

The distance snow is thrown can be adjusted by adjusting the angle of the chute assembly. Refer to the “Know Your Snow Thrower” section.

The remote chute control cables have been pre- adjusted at the factory. Move the remote chute lever on the control panel back and forward to adjust angle of the chute assembly.
