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.

Replacing the Shave Plate and Skid Shoes

The shave plate and skid shoes on the bottom of the snow thrower are subject to wear. These should be checked periodically and replaced when necessary

1.To replace, remove two carriage bolts and nuts securing each skid shoe to the auger housing. See Fig. 10

2.Reassemble new skid shoes with hardware just removed. Make sure the skid shoes are adjusted to be level.

3.To remove shave plate: Remove both skid shoes and hardware including carriage bolts and nuts which attach shave plate to the snow thrower housing. For location of shave plate, see Figure 10.

4.Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the housing. Reinstall skid shoes. Tighten securely.

Servicing Augers

The augers are secured to the spiral shaft with four shear pins and cotter pins. If you hit a foreign object or ice jam, the snow thrower is designed so that the pins may shear. Refer to Figure 10.

If the augers do not turn, check if the pins have sheared. Replace, if needed, with proper shear pins. Refer to item 42 on page 19 for part number.

IMPORTANT: NEVER replace the auger shear pins with standard pins or fasteners. 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.

1.Lubricate pivot points on the auger control and drive control with a light engine oil once a season.

2.Lubricate the auger idler bracket with a light engine oil once a season.
