If this is not possible, then refuel such machinery on a trailer with a portable container, rather than from a gasoline dispenser nozzle. – Keep the nozzle in contact with the rim of the fuel tank or container opening at all times, until refueling is complete. Do not use a nozzle lock-open device. – Replace gasoline cap securely and wipe up spilled fuel.

Figure 32 1. Electric-starter button 2. Electric starter plug-in 3. Recoil starter Note: To use the electric starter, connect a power cord to the electric starter plug-in first and then to a power outlet. Use only a UL-listed, 16-gauge extension cord recommended for outdoor use that is not longer than 50 feet (15 m). Figure 29 5. Rotate the choke to the Choke position (Figure 30). WARNING The electrical cord can become damaged, causing a shock or fire.
PAGE 17
Stopping the Engine Important: If the machine moves when the traction lever is in the released position, check the traction cable (refer to Checking and Adjusting the Traction Cable) or take the machine to an Authorized Service Dealer for service. 1. Move the throttle to the Slow position, and then to the Stop position (Figure 33). Important: To operate the traction drive, you must operate the machine with the self-propel feature engaged. Refer to Freewheeling or Using the Self-propel Drive. 1.

Note: Similarly, squeezing the left wheel clutch lever turns the machine to the left. When you complete the turn, release the wheel clutch lever, and the drive re-engages both wheels (Figure 37). Figure 39 2. To stop the auger and impeller, release the right hand lever. Figure 37 Important: When you engage both the auger/impeller lever and the traction lever, the traction lever locks the auger/impeller lever down, freeing your right hand.
PAGE 19
Unclogging the Discharge Chute Moving the Discharge Chute Hold the blue trigger cap down and move the Quick Stick to the left to move the discharge chute to the left; move the Quick Stick to the right to move the discharge chute to the right (Figure 41). If the auger/impeller is running but there is no snow coming out of the discharge chute, the discharge chute may be clogged. • To unclog the discharge chute, stay in the operating position and release the left hand (traction) lever.
PAGE 20
Operating Tips WARNING The rotor blades can throw stones, toys, and other foreign objects and cause serious personal injury to the operator or to bystanders. DANGER When the machine is in operation, the impeller and auger can rotate and cut off or injure hands and feet. • Keep the area to be cleared free of all objects that the rotor blades could pick up and throw. • Before adjusting, cleaning, inspecting, troubleshooting, or repairing the machine, stop the engine and wait for all moving parts to stop.
