Engine
Refer to the separate engine manual packed with your unit for all
engine lubrication instructions.
gear Shaft
The gear (hex) shaft should be lubricated at least once a season or
after every 25 hours of operation.
1. Drain the gasoline from the snow thrower, or place a piece of
plastic film under the gas cap.
2. Carefully pivot the snow thrower up and forward so that it rests on
the auger housing.
3. Remove the lower frame cover by removing the two screws which
secure it.
4. Apply a light coating of an all-weather multi-purpose oil to the hex
shaft. See Figure 15.
5. If you placed plastic film under the gas cap, be certain to remove
it before operating the snow thrower.
NOTE: Avoid getting oil on rubber friction wheel and aluminum drive
plate.
Chute Directional Control
Once a season, the joystick should be lubricated with petroleum jelly,
linseed oil, mineral oil, paraffin wax or 3-in-1 oil.
Auger Shaft
At least once a season, remove the shear pins on auger shaft. Spray
lubricant inside shaft, around the spacers. Also lubricate the flange
bearings found at either end of the shaft. See Figure 19.
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.

1. Remove the four carriage bolts and hex flange nuts which secure
them to the snow thrower.
2. Reassemble new skid shoes with the four carriage bolts (two on
