Tighten any loose fasteners. 3. Check and maintain the auger. 4. After each use, remove all snow and slush off the snow thrower to prevent freezing of auger or controls. 5. Check controls to make sure they are functioning properly. 6. If any parts are worn or damaged, replace immediately. 19 MAINTENANCE LUBRICATE AUGER GEAR BOX The auger gear box is lubricated at the factory and should not require additional lubrication. If for some reason the lubricant should leak out, or if the auger gear box has been serviced, add Lubriplate GR132 Grease or equivalent. Maximum 3- 1/4 ounces, (92 grams) should be used. Remove filler plug (AA, Figure 16), once a year. If grease is visible, do not add. If grease is not visible, use a piece of fine wire, like a dipstick to check if there is grease in the gear box. Mobilux EP1 and Shell Alvania EP1 are suitable equivalents. C A B B Lubricating Auger Gear Box Figure 16 LUBRICATE AUGER SHAFT FITTINGS 1. Using a hand grease gun, lubricate the auger shaft fittings (BB, Figure 16) every ten (10) operating hours. Each time a shear pin is replaced, the auger shaft (CC) MUST be greased. (See “Auger Shear Pin Replacement” section.) 2. For storage or when replacing shear pins, remove shear pins and lubricate auger shaft fittings (BB). Rotate augers several times on the shaft and reinstall the shear pins. CHECK/LUBRICATE FREE-HAND LINKAGE Check the function of the Free-Hand controls. The controls should function as described in the OPERATION section. WARNING: It is critical for the safe operation of the unit that the controls disengage when released. If the controls do not function properly, llubricate the controls (see Figure 17). NOTICE: Under no circumstances should the unit be used if the controls do not function properly. Lubricating Controls Figure 17 LUBRICATE CHUTE ROTATION GEAR Lubricate the chute rotation gear (AA, Figure 18) and shaft (BB) with automotive type oil every twenty-five (25) operating hours . ADJUST THE DRAG ON THE CHUTE ROTATION NOTE: After repeated use, the chute rotation gear may loosen, causing the chute to move back to the center position. Adjust the drag by tightening the nut (CC, Figure 18). Tightening the nut will limit the chute from moving without the operator turning the chute rotation crank. C A B Chute Rotation Gear Figure 18 20 MAINTENANCE ENGINE MAINTENANCE Check Crankcase Oil Level -Before starting engine and after each 8 hours of continuous use. Add the recommended motor oil as required. NOTE: Over filling the engine can affect performance. Tighten the oil fill cap securely to prevent leakage. Change Oil -Every 50 hours of operation or at least once a year, even if the snow thrower is not used for fifty hours. Use a clean, high quality detergent oil. Fill the crankcase to FULL line on dipstick (AA, Figure 19). Be sure original container is marked: A.P.I. service “SF” or higher. Do not use SAE10W40 oil (as it may not provide proper lubrication). See Chart for oil recommendations. Drain Oil – Position snow thrower so that the oil drain plug (AA, Figure 20) is lowest point on engine. When the engine is warm, remove oil drain plug and oil fill cap and drain oil into a suitable container. Replace oil drain plug and tighten securely. Refill crankcase with the recommended motor oil.

Remove the choke control knob (AA, Figure 21). 2. Remove the safety key (BB). 3. Remove the mounting screws (AA, Figure 22). 4. Slowly remove the snow hood (BB) Make sure that the primer button hose (CC) and the ignition wire (DD) are not disconnected. 5. The spark plug (EE) can now be accessed. 6. To install the snow hood, first make sure that the primer button hose and the ignition wire are connected. 7. Mount the snow hood to the engine and secure with the mounting screws. 8. Connect the choke control knob (AA, Figure 23) with the choke shaft on the carburetor (BB). Make sure the choke control knob is properly installed. If the choke control knob is not installed correctly, the choke will not operate. 9. Install the safety key (CC).

Replace the spark plug (Figure 24) if the electrodes are pitted or burned or if the porcelain is cracked. 1. Remove snow hood (see “Remove the Snow Hood” section). 2. Clean spark plug and reset gap periodically. 3. Clean area around spark plug base before removal, to prevent dirt from entering engine. 4. Replace spark plug if electrodes are pitted or burned or if porcelain is cracked. 5. Clean spark plug by carefully scraping electro...
