Electric Chute-Rotation Motor

The gear on the electric chute-rotation motor and the base of the discharge chute itself should be lubed with multi-purpose automotive grease once a season. See Figure 11.

Gear Case

The gear case is equipped with a grease fitting on the left housing and should be lubricated with Shell Alvania grease EPR00, part number 737-0168 every 25 hours. See Figure 12.

Do not overfill the gear case. Damage to the seals could result. Be sure the vent plug is free of grease in order to relieve pressure.

Auger Shaft

At least once a season, remove the shear bolts on the auger shaft. Spray lubricant inside the shaft. Also lubricate the plastic auger bearings at least once a season and grease the fittings on the end of the auger shaft with a standard grease gun. See Figure 12.

SECTION 7: SERVICING YOUR SNOW THROWER

WARNING: Before servicing, repairing, or inspecting, disengage all clutch levers and stop engine. Wait until all moving parts have come to a complete stop. Disconnect spark plug wire and ground it against the engine to prevent unintended starting.

Engine

Refer to the separate engine manual packed with your unit for all engine maintenance procedures.

Augers

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

Refer to Figure 12.

If the augers will not turn, check to see if the bolts have sheared. Replacement shear bolts and hex lock nuts have been provided with the snow thrower. When replacing bolts, spray an oil lubricant into shaft before inserting new bolts.

IMPORTANT:NEVER replace the auger shear bolts with standard hex bolts. Any damage to the auger gearbox

or other components as a result of doing so will NOT be covered by your snow thrower’s warranty.

Shave Plate and Skid Shoes

The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. They should be checked periodically and replaced when necessary. To remove the skid shoes, proceed as follows:

Remove the six carriage bolts, bell washers, and hex nuts which attach them to the snow thrower.

Reassemble new skid shoes with the six carriage bolts, bell washers (cupped side goes against skid

shoes) and hex nuts. Make certain the skid shoes are adjusted to be level.

To remove shave plate, remove the carriage bolts, bell washers, and hex nuts which attach it to the snow thrower housing. Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the housing. Tighten securely.

Belt Removal And Replacement

Auger Belts

Remove the plastic belt cover by removing the two self-tapping screws. See Figure 13.
