SECTION 7: SERVICING YOUR SNOW THROWER
WARNING: Before servicing, repairing, or inspecting, disengage all controls 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. Always wear safety glasses during operation or while performing any adjustments or repairs.
Augers
•The augers are secured to the spiral shaft with four (Model 1028) or six (Model 1130) shear pins and cotter pins. If you hit a hard foreign object or ice jam, the snow thrower is designed so that the bolts may shear. Refer to Figure 15.
•If the augers will not turn, check to see if the pins have sheared. Replacement shear pins and cotter pins have been provided with the snow thrower. When replacing pins, spray an oil lubricant into shaft before inserting new pins.
IMPORTANT:NEVER replace the auger shear pins with standard pins. 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.
•Remove the carriage bolts and flange lock nuts which attach the two skid shoes to the snow thrower on two sides. See Figure 12.
•Reassemble new skid shoes with the hardware removed earlier. Make certain the skid shoes are adjusted to be level.
•To remove the shave plate, remove the carriage bolts and flange lock nuts which attach the shave plate to the snow thrower housing. See Figure 15.
