Operating Tips

NOTE: Allow the engine to warm up for a few minutes as the engine will not develop full power until it reaches operating temperature.

WARNING: Muffle, engine, and surround- ing areas become hot and can cause a burn. Do not touch.

Set the skid shoes 1/4" below the shave plate for normal usage. The skid shoes may be adjusted

upward (to lower the shave plate) for hard-packed snow. Adjust downward (to raise the shave plate) when using on gravel or crushed rock.

For most efficient snow removal, remove snow immediately after it falls.

Discharge snow downwind whenever possible and slightly overlap each previous cleared path.

Follow the precautions found under the heading To Stop Engine to prevent possible freeze-up.

Clean the snow thrower thoroughly after each use.

SECTION 5: MAKING ADJUSTMENTS

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

Skid Shoe Adjustment

The space between the shave plate and the ground can be adjusted by raising or lowering the skid shoes. Refer to Skid Shoe Adjustment in the Assembly Section.

Chute Assembly Adjustment

The distance snow is thrown can be adjusted by adjusting the angle of the chute assembly. Refer to the Chute Tilt Control in the Know Your Snow Thrower Section.

Auger Control Adjustment

Refer to the information found under Final Adjustments in the Assembly Section to adjust the auger control.

Chute Directional Control And Support Bracket Adjustment

If the spiral at the base of the chute directional control is not fully engaging with the notches in the lower chute assembly, the support bracket can be adjusted inward or outward as follows:

Loosen, but do NOT remove the two hex nuts which secure the chute directional control support bracket to the snow thrower housing. See Figure 8.

Adjust the support bracket inward or outward so that the spiral is fully engaged in the notches on the chute before retightening the hex nuts.

Traction Control Adjustment

Refer to the information found under Final Adjustments in the Assembly Section to adjust the traction control. If you are uncertain that you have reached the correct adjustment, proceed as follows:

WARNING: Drain the gasoline out of your snow thrower’s engine or 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 9.

If adjustment is necessary:

Loosen the jam nut on the traction drive cable and thread the cable in or out as necessary.

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.
