SECTION 5: MAKING 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 changing the angle of the chute assembly. Refer to Chute Tilt Control on page 10.

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.

Auger Control

Refer to details on page 7 to adjust the auger control.

Skid Shoe

The space between shave plate and ground can be adjusted by raising or lowering the skid shoes. Refer to Skid Shoe Adjustment on page 8.

Traction Control

Refer to Final Adjustments on page 7 to adjust traction control. If you are want to check further for correct adjustment, proceed as follows:

WARNING: Drain the gasoline out of your snow thrower’s engine, place a piece of plastic film under the gas cap to avoid spillage before beginning to perform this adjustment.

Tip the snow thrower forward, allowing it to rest on the auger housing.

Remove the frame cover underneath the snow thrower by removing six self-tapping screws.

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

With the traction control engaged, the friction wheel must contact the drive plate. See Figure 14.

Place shift lever in sixth (6) position.

Rotate the shift arm counterclockwise (from the operator’s position) as far as it will go.

Thread the upper shift rod downward until the elbow on its lower end aligns with the hole found in the lower shift rod.

Reconnect the upper shift rod to the lower shift rod by reinserting the cotter pin removed earlier and sliding the connector back down into place.

IMPORTANT: Check for correct adjustment of the shift rod as instructed on page 7, before operating the snow thrower.
