Operation Clearing a Clogged Discharge Chute • Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times. WARNING • Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. Hand contact with the rotating rotor blades inside the discharge chute is the most common cause of injury associated with machines. Never use your hand to clean out the discharge chute.
PAGE 4
• Do not smoke while handling gasoline. • Do not use the machine on a roof. • Do not touch the engine while it is running or soon after it has stopped because the engine may be hot enough to cause a burn. • Perform only those maintenance instructions described in this manual. Before performing any maintenance, service, or adjustment, stop the engine and remove the key. If major repairs are ever needed, contact an Authorized Service Dealer. • Do not change the governor settings on the engine.

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 10
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.

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.

Disengaging the Rotor Blades To disengage the rotor blades, release the control bar (Figure 20). Figure 20 Stopping the Engine To stop the engine, turn the ignition key counterclockwise to the Off position (Figure 21). 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).

Operating Tips • Shut the engine off ! • Wait 10 seconds to be sure the rotor blades have stopped WARNING rotating. • Always use a cleanout tool, not your hands. The rotor blades can throw stones, toys, and other foreign objects and cause serious personal injury to the operator or to bystanders. Preventing Freeze-up after Use • Keep the area to be cleared free of all objects that the rotor blades could pick up and throw. • Let the engine run for a few minutes to prevent moving parts from freezing.
PAGE 14
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.

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.

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. Fuel tank cap 4. Small screw 2. Large screws (3) 5. Chute seal Figure 35 1. Center electrode insulator 3. Discharge chute 3.

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.

4. Hold the discharge chute in the straight-ahead position, pull the lower cable casing downward until you remove the slack in the cable, and tighten the screw on the lower cable clamp securely (Figure 43). Figure 43 1. Lower cable casing 5. Pull the upper cable casing forward until you remove the slack in the cable, and tighten the screw on the upper cable clamp securely (Figure 44). Figure 44 1. Upper cable casing Note: Do not over-tension the cables.
