Never attempt to clean the chute or make any adjustments while the engine is running.

Adjustments

Traction Drive Control

Refer to the Final Adjustment section of the Set-Up Instructions to adjust the traction drive control. If you are not sure of proper adjustment, check as follows.

•Drain the gasoline or place plastic film under the gas cap if the snow thrower has already been operated.

•Tip the snow thrower forward and remove the four self-tapping screws that hold the frame cover underneath the snow thrower.

•With the traction drive control released, make sure that there is clearance between the friction wheel and the friction plate in all positions of the shift lever. See Figure 22.

NOTE: If you placed plastic under the gas cap, be certain to remove it.

Augers

The augers are secured to the spiral shaft with two shear bolts and hex lock nuts. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts will shear.

•If the augers will not turn, check to see if the bolts have sheared. Replace if necessary. See Figure 23. Two replacement shear bolts and hex lock nuts have been provided in Group D of the hardware pack which is illustrated on page 5.

•With the traction drive control engaged, make sure that the friction wheel is making contact with the friction plate. Also make sure that the overtravel spring is stretched.

•If adjustment is necessary, loosen the jam nut on the traction drive cable and thread the cable in or out as necessary.

•Tighten the jam nut to secure the cable when correct adjustment is reached. Reassemble the frame cover.

The space between the shave plate and the ground can be adjusted by adjusting the skid shoe. Refer to page 11 of this manual.

Shift Rod

To adjust the shift rod, proceed as follows.

•Remove the hairpin clip and flat washer from the ferrule underneath the shift panel. Remove the ferrule from the hole in the shift lever.

•Place the shift lever on the handle panel in the sixth (6) speed position (all the way forward).

•Push down on the shift rod (and shift arm assembly) as far as it will go. Hold it in this position. See Figure 24.

•Thread the ferrule up or down the shift rod as necessary until the ferrule lines up with the upper hole in the shift lever.
