Product Overview g004217 Figure 22 1. Snow-cleanout tool (attached to the handle) Operation Note: Determine the left and right sides of the machine from the normal operating position. Before Operation Before Operation Safety • For electric-start models only: Use extension cords and receptacles as specified in the manual. Thoroughly inspect the electrical cord before plugging it into a power source. If the cord is damaged, do not use it. Replace the damaged cord.
DANGER Fuel is extremely flammable and explosive. A fire or explosion from fuel can burn you and others. • 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. • Fill the tank outdoors when the engine is cold. Wipe up spills. • Do not handle fuel when smoking or around an open flame or sparks. • Store fuel in an approved fuel container, out of the reach of children.
• 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). g018812 g018812 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. WARNING G016501 The electrical cord can become damaged, causing a shock or fire. g016501 Figure 27 Thoroughly inspect the electrical cord before using the machine. If the cord is damaged, do not use it.
Operating the Handwarmers 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. Operate the handwarmers as follows: • Press the switch to the ON position to turn on the handwarmers. • Press the switch to the OFF position to turn off the handwarmers. STOP G016505 g016505 Figure 30 2. Wait for all moving parts to stop before leaving the operating position.
g001308 Figure 35 g001011 Figure 33 Momentarily squeezing and releasing the left or right wheel-clutch lever also allows for steering adjustments to keep the machine going in a straight line, especially in deep snow. 2. To stop the traction drive, release the traction lever. Squeezing both wheel-clutch levers simultaneously disengages the drive to both wheels. This enables you to manually move the machine backward without stopping to shift it into a reverse gear.
Operating the Quick Stick® Operating the Auger/Impeller Drive Hold the blue trigger cap down to use the Quick Stick to move the discharge chute and the chute deflector. Release the trigger cap to lock the discharge chute and chute deflector into position (Figure 38). 1. To engage the auger/impeller drive, squeeze the right (auger/impeller) lever to the handgrip (Figure 37). g001013 Figure 37 g001014 Figure 38 2. To stop the auger and impeller, release the right lever.
Moving the Chute Deflector Operating Tips 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 40). DANGER When the machine is in operation, the impeller and auger rotate and can injure or amputate hands or feet. • Before adjusting, cleaning, inspecting, troubleshooting, or repairing the machine, shut off the engine and wait for all moving parts to stop.
After Operation After Operation Safety • 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. • When storing the machine for more than 30 days, refer to Storage (page 26) for important details. Preventing Freeze-up after Use • In snowy and cold conditions, some controls and moving parts may freeze.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. 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.
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 44). g001569 Figure 46 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 44 1. Jam nut 2. Turnbuckle 5. Loosen the jam nut (Figure 47).
Checking the Auger-Gearbox-Oil Level Service Interval: Yearly—Check the auger-gearbox oil and add oil if necessary. 1. Move the machine to a level surface. 2. Clean the area around the pipe plug (Figure 48). g011606 Figure 49 1 Engine Oil Capacities G016782 Model Engine Oil Capacity 38833 0.89 to 0.95 L (30 to 32 oz) g016782 Figure 48 1. Pipe plug 1. Clean the area around the oil-drain cap (Figure 50). 3. Remove the pipe plug from the gearbox. 4. Check the oil level in the gearbox.
Replacing the Spark Plug Service Interval: Every 100 hours—Replace the spark plug. WARNING Replacing the spark plug while the engine is hot can result in burns. g001029 Figure 53 1. 0.76 mm (0.030 inch) Wait until the engine is cool to replace the spark plug. 5. Install the new spark plug, tighten it firmly, and attach the ignition wire to the spark plug. Use a Toro spark plug or equivalent (Champion® RN9YC or NGK BPR6ES).
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). 2. Turn the base of the bulb counterclockwise until it stops (Figure 58). g001033 Figure 58 3. Remove the bulb straight out from the back of the headlight (Figure 59). g001032 Figure 56 1. Discharge-chute latch 2. Gear teeth Note: The latch is spring loaded and naturally moves into the teeth of the gear (Figure 56). g001034 4.
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. g006590 2. Run the engine for 10 minutes to distribute the conditioned fuel through the fuel system. Figure 62 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.
