Maintenance & Adjustments 6 Maintenance WARNING! Before servicing, repairing, lubricating, or inspecting, disengage all controls and stop engine. Wait until all moving parts have come to a complete stop. Remove the ignition key, disconnect the 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. Engine Refer to the Engine Operators Manual Maintenance included with the snow thrower. 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. NOTE: The skid shoes on this machine have two wear edges. When one side wears out, they can be rotated 180° to use the other edge. To Replace skid shoes: 1. Remove the six carriage bolts, hex nuts, and bell washers that secure the two skid shoes to the sides of the auger housing. Refer to Figure 6-1. 3. Slide the shave plate out of the off-set slot at the bottom of the housing, and from between the skid shoes and side panels of the housing. 4. With the mounting holes facing toward the back of the unit, slide the new shave plate into position and secure with the fasteners previously removed and loosened. Lubrication Gear Shaft The gear (hex) shaft should be lubricated at least once a season or after every twenty-five (25) hours of operation. NOTE: Before tipping the unit on the front housing, run the fuel tank empty to avoid a fuel leak. 1. Carefully pivot the snow thrower up and forward so that it rests on the auger housing. 2. Remove the frame cover from the underside of the snow thrower by removing the self-tapping screws which secure it. Refer to Figure 6-6. 3. Apply a light coating of engine oil (or 3-in-1 oil) to the hex shaft. See Figure 6-2. NOTE: When lubricating the hex shaft, be careful not to get any oil on the aluminum drive plate or the rubber friction wheel. Doing so will hinder the snow thrower's drive system. Wipe off any excess or spilled oil. 4. At least once a season grease the wheel axle with Arctic grease, part number 737-0318. The grease fitting is located on the wheel axle tube behind the wheel axle support bracket. Rubber Friction Wheel Hex Shaft Aluminum Drive Plate Figure 6-1 2.
