DANGER Fuel is extremely flammable and explosive. A fire or explosion from fuel can burn you and others. g004217 Figure 22 • To prevent a static charge from igniting the fuel, place the container and/or machine on the ground before filling, not in a vehicle or on an object. 1. Snow-cleanout tool (attached to the handle) Operation • Fill the tank outdoors when the engine is cold. Wipe up spills. Note: Determine the left and right sides of the machine from the normal operating position.
• Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. • Never attempt to make any adjustments while the engine is running. • After striking a foreign object, shut off the engine, remove the ignition key (electric-start models only), thoroughly inspect the machine for any damage, and repair the damage before starting and operating the machine.
5. Move the choke to the CHOKE position (Figure 27). 1 G016498 g016498 Figure 25 1. Ignition key G016501 4. Firmly push in the primer with your thumb as indicated by the following table, holding the primer in for a second before releasing it each time (Figure 26). g016501 Figure 27 6. Move the throttle to the FAST position (Figure 28). STOP G016504 g016504 Figure 28 g037221 g037221 7. Start the machine by pulling the recoil starter or pressing the electric-starter button (Figure 29).
Shutting Off the Engine 1. Move the throttle to the SLOW position, and then to the STOP position (Figure 30). You can also shut off the engine by pulling the ignition key outward to the middle position. STOP g215361 Figure 29 1. Electric-starter button 2. Electric starter plug-in 3. Recoil-start handle Note: Use only an extension cord that is UL-listed, 16 gauge, not longer than 15 m (50 ft), and is designed for outdoor use. G016505 g016505 Figure 30 WARNING 2.
Using the Wheel-Clutch Levers Operating the Traction Drive The wheel-clutch levers allow you to momentarily disengage the drive to 1 or both wheels with the traction-drive lever still engaged. This enables you to turn and maneuver the machine easily. CAUTION If the traction drive is not properly adjusted, the machine may move in the direction opposite of what you intended, causing injury and/or property damage.
Operating the Speed Selector WARNING If the auger and impeller continue to rotate when you release the auger/impeller lever, you could seriously injure yourself or others. The speed selector has 6 forward and 2 reverse gears. To change speeds, release the traction lever and shift the speed-selector lever to the desired position (Figure 35). The lever locks in a notch at each speed selection. Do not operate the machine. Take it to an Authorized Service Dealer for service.
Moving the Chute Deflector • If the chute does not move, refer to Adjusting the Discharge-Chute Latch (page 25). Hold the blue trigger cap down and move the Quick Stick forward to lower the chute deflector; move it rearward to raise the chute deflector (Figure 39). • If the chute does not turn as far to the left as it does to the right, ensure that the cable is routed to the inside of the handles. Refer to 1 Installing the Upper Handle (page 6).
Operating Tips After Operation DANGER After Operation Safety When the machine is in operation, the impeller and auger rotate and can injure or amputate hands or feet. • Never store the machine with fuel in the fuel tank inside a building where ignition sources are present, such as hot water heaters, space heaters, or clothes dryers. Allow the engine to cool before storing in any enclosure.
Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval Maintenance Procedure After the first 2 hours • Inspect the traction cable and adjust it if necessary. • Inspect the auger/impeller cable and adjust it if necessary. After the first 5 hours • Change the engine oil. Before each use or daily • Check the engine-oil level and add oil if necessary. Every 50 hours • Change the engine oil.
4. Ensure that the scraper is 3 mm (1/8 inch) above and parallel to a level surface. Note: If the pavement is cracked, rough, or 1 uneven, adjust the skids to raise the scraper. For gravel surfaces, adjust the skids further down to prevent the machine from picking up rocks. 5. Move the skids down until they are even with the ground. 6. Firmly tighten the nuts that secure both skids to the auger sides.
1. Loosen the jam nut. 2. Loosen or tighten the turnbuckle to adjust the pin until it is the proper gap from the front edge of the slot. 3. Tighten the jam nut (Figure 43). g001569 Figure 45 1. Tab 2. 1.5 mm (1/16 inch) g001021 4. If the auger/impeller cable is not properly adjusted, do the following steps: Figure 43 1. Jam nut 2. Turnbuckle 5. Loosen the jam nut (Figure 46).
Changing the Engine Oil Checking the Auger-Gearbox-Oil Level Service Interval: After the first 5 hours—Change the engine oil. Service Interval: Yearly—Check the auger-gearbox oil and add oil if necessary. Every 50 hours—Change the engine oil. Change the engine oil every 25 operating hours when operating the engine under a heavy load. 1. Move the machine to a level surface. 2. Clean the area around the pipe plug (Figure 47).
2. Slide an oil-drain pan under the drain extension and remove the oil-drain plug. Replacing the Spark Plug Note: When removing the plug, ensure that the Service Interval: Every 100 hours—Replace the spark plug. tube does not loosen. WARNING 3. Drain the oil. Replacing the spark plug while the engine is hot can result in burns. Note: Dispose of the used oil properly at a local recycling center. Wait until the engine is cool to replace the spark plug. 4. Install the oil-drain plug. 5.
3. Grasp the cable conduit and move it toward the front of the machine until the discharge-chute latch fully engages the gear teeth (Figure 55 and Figure 56). g001029 Figure 53 1. 0.76 mm (0.030 inch) 5. Install the new spark plug, tighten it firmly, and attach the ignition wire to the spark plug. Note: Ensure that the ignition wire snaps completely into place on the spark plug. g001032 Figure 56 Adjusting the Discharge-Chute Latch 1. Discharge-chute latch 2.
Replacing the Headlight Bulb Use a GE 899 37W halogen light bulb. Do not touch the bulb with your hands or allow dirt or moisture to come into contact with the bulb. g001035 1. Remove the wire connector from the back of the headlight (Figure 57). Figure 60 5. Turn the base of the bulb clockwise until it is snug (Figure 61). g001037 Figure 57 g001036 Figure 61 2. Turn the base of the bulb counterclockwise until it stops (Figure 58). 6.
Storage Preparing the Machine for Storage 1. On the last refueling of the year, add fuel stabilizer to fresh fuel as directed by the engine manufacturer. Important: Do not store fuel longer than that suggested by the fuel-stabilizer manufacturer. 2. Run the engine for 10 minutes to distribute the conditioned fuel through the fuel system. 3. Run the machine until the engine runs out of fuel. 4. Prime the engine and start it again. 5. Allow the engine to run until it shuts off.
Troubleshooting Problem Possible Cause The electric starter does not turn (electric start only). 1. The power cord is disconnected at the outlet or the machine. 1. Connect the power cord to the outlet and/or the machine. 2. The power cord is worn, corroded, or damaged. 3. The power outlet is not energized. 2. Replace the power cord. 1. The key is not in the ignition or is in the STOP position. 1. Insert the key into the ignition and turn it to the ON position. 2.
Problem The engine runs, but the machine discharges snow poorly or not at all. Possible Cause Corrective Action 1. The throttle is not in the FAST position when throwing snow. 1. Move the throttle to the FAST position. 2. The machine is moving too fast to clear the snow. 3. You are trying to remove too much snow per swath. 4. You are trying to remove extremely heavy or wet snow. 5. The discharge chute is plugged. 6. The auger/impeller drive belt is loose or is off the pulley. 2.
