Toro Snowthrower Safety • Do not overload the machine capacity by attempting to • • • • clear snow at too fast a rate. Look behind and use care when backing up with the machine. Disengage power to the rotor blades when machine is transported or not in use. Never operate the machine without good visibility or light. Always be sure of your footing, and keep a firm hold on the handles. Walk; never run. Never touch a hot engine or muffler (Figure 3).

Operation Note: Determine the left and right sides of the machine from the normal operating position. DANGER Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others. • To prevent a static charge from igniting the gasoline, 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. Figure 11 1.
PAGE 9
Note: You may tip the machine forward (handle up) to make adding oil easier. Remember to return the machine to the operating position before checking the oil level. 3. Firmly push in the primer with your thumb as indicated by the chart below, holding in the primer for a second before releasing it each time (Figure 16). Important: Do not tip the machine all the way forward onto its nose, or fuel may leak out of the machine. Number of primes Temperature 3 0°F (-18°C) or above 6 Below 0°F (-18°C) 5.
PAGE 10
Engaging the Rotor Blades WARNING The electrical cord can become damaged, causing a shock or fire. To engage the rotor blades, hold the control bar against the handle (Figure 19). Thoroughly inspect the electrical cord before plugging it into a power source. If the cord is damaged, do not use it to start the machine. Replace or repair the damaged cord immediately. Contact an Authorized Service Dealer for assistance. Figure 19 1.
PAGE 11
Disengaging the Rotor Blades To disengage the rotor blades, release the control bar (Figure 20). Figure 22 To raise or lower the angle of the chute deflector, press the trigger on the chute deflector and move the chute deflector up or down (Figure 23). Figure 20 Stopping the Engine To stop the engine, turn the ignition key counterclockwise to the Off position (Figure 21). Figure 23 1. Chute deflector trigger 2.
PAGE 12
Preventing Freeze-up after Use • If the machine does not propel itself forward on slippery surfaces or in heavy snow, push forward on the handle, but allow the machine to work at its own pace. • Let the engine run for a few minutes to prevent moving parts from freezing. Stop the engine, wait for all moving parts to stop, and remove ice and snow from the machine. • Overlap each swath to ensure complete snow removal. • Discharge the snow downwind whenever possible.
PAGE 13
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 • Check the control cable and adjust it if necessary. • Check for loose fasteners and tighten them if necessary. After the first hour After the first 2 hours Before each use or daily • Change the engine oil. • Check the engine oil level and add oil if necessary. • Check the control cable and adjust it if necessary.
PAGE 14
Note: Moving the Z-fitting higher decreases the gap between the control bar and the handle; moving it lower increases the gap. 3. Hook the spring to the adjuster link and slide the spring cover over the adjuster link. 4. Check the adjustment; refer to Checking the Control Cable. Note: After extended use, the drive belt may wear and lose its proper belt tension.

Figure 30 1. Oil fill cap Figure 32 7. Unscrew the oil fill cap and remove it (Figure 30). 9. Wait 3 minutes for the oil to settle and add enough to bring it to the point of overflow. 8. With the machine in the operating position, carefully pour oil into the oil fill hole to the point of overflow (Figure 32). 10. Screw the oil fill cap into the oil fill hole, and hand tighten it securely. Note: You may tip the machine forward (handle up) to make adding oil easier.

9. Clean around the spark plug. 10. Remove the spark plug from the cylinder head. Important: Replace a cracked, fouled, or dirty spark plug. Do not clean the electrodes because grit entering the cylinder can damage the engine. 11. Set the gap on the plug to 0.030 inch (0.76 mm) (Figure 35). Figure 33 1. Large screws (3) 4. Small screw 2.

Note: The small screw goes through the small hole in the chute seal at the front of the discharge chute opening. Note: Route the new drive belt first around the engine pulley, then the idler pulley, and finally around the loose rotor pulley positioned just above the rotor shaft (Figure 37). Replacing the Drive Belt 6. Install the rotor pulley onto the rotor shaft (Figure 37). If drive belt becomes worn, oil-soaked, excessively cracked, frayed, or otherwise damaged, replace the belt. 1.

Storage 16. Cover the machine and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure. Storing the Snowthrower WARNING • Gasoline fumes are highly flammable, explosive, and dangerous if inhaled. If you store the machine in an area with an open flame, the gasoline fumes may ignite and cause an explosion.
