Maintaining

Your Snow

Thrower

WARNING

Before lubricating, repairing, or inspect- ing, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop.

Keep all grease and oil off of the rubber friction wheel and aluminum drive plate.

Engine

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

Lubrication

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.

WARNING: Run the engine com- pletely dry of gasoline before tipping snowthrower.

1.Carefully pivot the snow thrower up and forward so that it rests on the auger housing.

2.Remove the lower frame cover by removing the screws which secure it.

3.Apply a light coating of an all-weather multi-purpose oil to the hex shaft. See Figure 6-1.

NOTE: Avoid getting oil on rubber friction wheel and aluminum drive plate.

Wheels

At least once a season, remove both wheels. Clean and coat the axles with a multipurpose automotive grease before reinstalling wheels.

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 6-2.

Augers

The augers are secured to the spiral shaft with shear pins and cotter pins. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Figure 6-2.

If the augers will not turn, check to see if the pins have sheared. One set of replacement shear pins has been provided with the snow thrower. When replacing pins, spray an oil lubricant into shaft before inserting new pins.

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 skid shoes:

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 each side) and hex flange nuts. Refer to Figure 6-3.
