mechanism at least once a season. Use engine oil or a spray lubricant. Avoid getting oil on the friction wheel rubber and aluminum drive plate. Refer to Figure 9.
There is a grease fitting on the top of the axle shaft which drives the rear track drive wheels on both sides of the unit. Grease these fittings every 25 hours or once a season.
Traction Control / Auger Control Lock
The cams on the ends of the control rods which interlock the traction drive and auger drive controls must be lubricated at least once a season or every 25 hours of operation. The cams can be accessed beneath the handle panel. Use a

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
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.
