Adjustments

WARNING

Read, understand, and follow all instructions and warnings on the machine and in this manual before operat- ing.

Never attempt to make any adjustments while the engine is running, except where specified in operator’s manual.

Specifications are subject to change without notification or obligation. Images may not reflect your exact model and are for reference purposes only.

Figure 5-1

Shift Rod

If the full range of speeds (forward and reverse) cannot be achieved, refer to the figure above and adjust the shift rod as follows:

1.Looking underneath the handle panel, note which of the three holes in the shift lever the ferrule is inserted into. Also note the direction of insertion. Remove the internal cotter pin and flat washer from the ferrule and withdraw the ferrule from the shift lever. See Figure 5-1.

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

3.Push shift rod and shift arm assembly down sharply as far as it will go to put the drive into the fastest forward position.

4.As necessary, rotate (thread) the ferrule up or down the shift rod until the ferrule lines up with the hole from which it was earlier removed. See Figure 5-1.

5.From the direction noted earlier, insert the ferrule into the proper hole.

6.Reinstall the washer and the internal cotter pin.

Chute Control

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

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.

Drive Control

Refer to the Final Adjustment section of the Assembly instructions to adjust the drive control. To further check the adjustment, proceed as follows:

1.With the snow thrower tipped forward (be certain to drain gasoline or place plastic film under the gas cap if the snow thrower has already been operated), remove the frame cover underneath the snow thrower by removing the self-tapping screws. See Figure 5-2.

2.Locate the opening between the axle support bracket and the front frame support (See Figure 5-3). Looking through this opening, with the drive control released, there must be 1/8” clearance between the friction wheel and the drive plate in all positions of the shift lever.

3.With the drive control engaged, the friction wheel must contact the drive plate. See Figure 5-3.

4.If there is no friction wheel clearance, or the friction wheel does not solidly contact the drive plate, re- adjust the lock nut on the lower end of the drive cable following the instructions in the Assembly section.

5.Reassemble the frame cover.
