The gear case is lubricated with grease at the factory and does not require checking. If disassembled for any reason, lubricate with 2 ounces of Shell Alvania grease EPR00, part number
IMPORTANT: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.

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 18.
•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.
Belt Removal And Replacement
Auger Belts
•Remove the plastic belt cover by removing the two
