SECTION 8: ADJUSTMENTS

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

CHUTE ASSEMBLY

The distance snow is thrown can be adjusted by adjusting the angle of the chute assembly. Refer to the Control section of this manual.

1.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 asssembly.

SKID SHOE

The space between the shave plate and the ground can be adjusted. For close snow removal, place skid shoes in the low position. Use middle or high position when area to be cleared is uneven.

1.Adjust skid shoes by loosening the four hex nuts and carriage bolts and moving skid shoes to desired position.

2.Make certain the entire bottom surface of skid shoe is against the ground to avoid uneven wear on the skid shoes.

3.Retighten nuts and bolts securely.

NOTE: It is not recommended that you operate this snow thrower on gravel as loose gravel can be easily picked up and thrown by the auger causing an injury or damage to the snow thrower.

4.If for some reason, you have to operate the snow thrower on gravel, keep the skid shoe in the highest position for maximum clearance between the ground and the shave plate.

TRACTION DRIVE CLUTCH

Refer to the Final Adjustment section of the Set-Up Instructions to adjust the traction drive clutch. To check the adjustment, proceed as follows:

1.With the snow thrower tipped forward (be certain to drain the 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 six self-tapping screws.

2.With the traction drive clutch released, there must be clearance between the friction wheel and the drive plate in all positions of the shift lever.

3.With the traction drive clutch engaged, the friction wheel must contact the drive plate

(shown in Figure 22).

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

necessary. See Figure 12. Tighten the jam nut to secure the cable when correct adjustment is reached. Reassemble the frame cover.

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

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

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

4.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 12.

5.Insert ferrule from the left side of the snowthrower into the upper hole in shift lever.

6.Reinstall the hairpin clip and the washer.

Make certain to check for correct adjustment before operating the snow thrower.

CARBURETOR

WARNING: If any adjustments are made to the engine while the engine is running (e.g. carburetor), keep clear of all

moving parts. Be careful of heated surfaces and mufflers.

Minor carburetor adjustments may be required to compensate for differences in fuel temperature, altitude and load.
