SECTION 8: ADJUSTMENTS

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

CHUTE ASSEMBLY ADJUSTMENT

The distance snow is thrown can be controlled by adjusting the angle of the top section of the chute assembly.

SKID SHOE ADJUSTMENT

The space between the shave plate and the ground can be adjusted. Refer to the Final Assembly and Adjustments section.

TRACTION DRIVE CLUTCH

ADJUSTMENT

Refer to the Final Assembly and Adjustments section to adjust the traction drive clutch. If you are uncertain that you have reached the correct adjustment, the adjustment can be physically checked as follows.

1.With the snow thrower tipped forward (be certain to drain the oil gasoline or drain the oil and 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. With the traction drive clutched engaged, the friction wheel must contact the drive plate. See Figure 21.

3.If adjustment is necessary, loosen the lock nut on the traction drive cable and thread the cable in or out as necessary. Tighten the lock 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.

AUGER CLUTCH ADJUSTMENT

To adjust the auger clutch, refer to Final Assembly and Adjustments section on page 10.

CARBURETOR ADJUSTMENT

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 muffler.

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

Refer to the separate engine manual packed with your unit for carburetor adjustment information.

DRIVE WHEELS

The wheels may be adjusted for two different methods of operation. The adjustment is made by placing the klick pins in one of two different holes on the right side of the unit. See Figure 22.

1.One Wheel Driving—On the right side of the unit, place klick pin in the outside axle hole only. Do not place pin through wheel hub. This position gives power drive to the left wheel only, making the unit easier to maneuver.

2.Both Wheels Driving—Rotate wheel assembly to align hole in hub with inner hole on axle shaft. Insert klick pin in hole. Outer axle shaft hole should be visible. See Figure 22.
