Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer. • Drain all the oil from the crankcase (this should be done after the engine has been operated and is still warm) and refill the crankcase with fresh oil. • If you have drained the fuel tank, protect the inside of the engine as follows. Remove spark plug, pour approximately 1/2 ounce (approximately one tablespoon) of engine oil into cylinder and crank slowly to distribute oil. Replace spark plug. OTHER • Do not store gasoline from one season to another. • Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems. • Store unit in a clean, dry area. Do not store next to corrosive materials, such as fertilizer. NOTE: If storing in an unventilated or metal storage shed, be certain to rustproof the equipment by coating with a light oil or silicone. SERVICE & ADJUSTMENT WARNING: ALWAYS STOP ENGINE A AND DISCONNECT SPARK PLUG WIRE AND MOVE IT AWAY FROM SPARK PLUG BEFORE PERFORMING ANY ADJUSTMENTS OR REPAIRS. 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, remove the four carriage bolts, belleville washers and hex nuts which attach them to the snow thrower. Reassemble new skid shoes with the four carriage bolts, belleville washers (cupped side goes against skid shoes) and hex nuts. Make certain the skid shoes are adjusted to be level. • To remove shave plate, remove the carriage bolts, belleville washers and hex nuts which attach it to the snow thrower housing. Reassemble new shave plate, making sure heads of the carriage bolts are to the inside of the housing. Tighten securely. 17 SERVICE & ADJUSTMENT BELT REMOVAL AND REPLACEMEN1 A WARNING: DISCONNECT THE SPARK PLUG WIRE FROM THE SPARK PLUG AND GROUND. To remove and replace either the rear or front auger drive belt, proceed with the following instructions. • Disconnect the chute crank at the chute assembly by removing the cotter pin and flat washer. • Remove the plastic belt cover on the front of the engine by removing two self-tapping screws. See figure 18. FIGURE 18. • Unthread the bottom of the auger cable fiom the top of the cable, leaving the hex nut in place. • Remove the six hex bolts, lock washers end hex nuts which attach the auger housing asse nbly to the frame. See figure 19. • Separate the housing from the frame assembly by standing in the operating position and lifting up on the handles. The frame and housing will se parate, and the rear auger drive belt will come off he pulleys. See figure 20. • To remove the front auger drive belt, push tne idler pulley to the left, and lift front auger drive b 3lt from the front auger pulley. See figure 21. Replase both auger drive belts by following instruct ons in reverse order. FIGURE 19. FIGURE 20. Front SERVICE & ADJUSTMENT • If a replacement drive belt is needed, follow previous instructions. Pull idler pulley up and lift belt off friction wheel disc. See figure 22. Reassemble in reverse order. NOTE: When reassembling the two halves of the unit, the auger drive cable must be routed through the cable roller guides as shown in figure 22. Idler Pulley • Remove the six screws from the friction wheel assembly (three from each side). Remove the friction wheel rubber from between the friction wheel plate. • Reassemble new friction wheel rubber to the friction wheel assembly, tightening the six screws in rotation and with equal force. • Slide the friction wheel assembly up onto the shift mechanism as shown in figure 24, and slide the gear shaft back into the unit. Reassemble in reverse order. rc=- g Cable Roller Guide Cable Friction Wheel Disc FIGURE 22. FIGURE 23. CHANGING THE FRICTION WHEEL RUBBER The rubber on the friction wheel is subject to wear and should be checked after 25 hours of operation, and periodically thereafter. Replace the friction wheel rubber if any signs of wear or cracking are found. • Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap. • Tip the snow thrower up and forward, so that it rests on the housing. • Remove four self-tapping screws from the frame cover underneath the snow thrower. • Remove the gear shaft from the unit by removing the bolts, lock washers and flat washers from each side of the frame. See figure 23. Hold the friction wheel assembly, and slide the gear shaft out of the unit toward the right hand side. Refer to figure 24.
