Safety Caution: Improper use may result in loss of fingers, hands, or feet. Before Operating ? ? Read and understand the contents of this manual before operating the snowthrower Become familiar with all controls and know how to stop the engine quickly . . There is a high-speed impeller close to the opening. Operator 's Position The low-speed auger has a moving pinch point close to the opening. This snowthrower meets or exceeds the B71.
– Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle, before filling. • When cleaning, repairing or inspecting the snow thrower, stop the engine and make certain the auger/impeller and all moving parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent someone from accidentally starting the engine.
Maintenance and Storage • If a shield, safety device, or decal is damaged, illegible, or lost, repair or replace it before beginning operation. • Check all fasteners at frequent intervals for proper tightness to be sure the equipment is in safe working condition. • Do not smoke while handling gasoline. • Do not use the snow thrower on a roof.

Product Overview • Traction Control Lever—To engage the traction (wheel drive), press the lever against the left handgrip. To stop the traction, release the lever. • Speed Selector Lever—This control has 4 positions: 3 forward speeds and 1 reverse. To change speeds, move the speed selector lever to the desired position. The lever locks in a notch at each speed selection. Note: Before shifting gears into or out of reverse, you must release the traction control lever.
Operation Note: Determine the left and right sides of the machine from the normal operating position. Freewheeling or Using the Self-propel Drive Figure 18 You can operate the snowthrower with the self-propel feature engaged or disengaged (freewheeling). 1. Spark-plug wire 2. Self-tapping screw To freewheel, slide the wheels inward and insert the axle pins through the outer axle holes, but not through the wheel hubs (Figure 16). 3. Carburetor heater box 4. Screws 1.
Installing the Carburetor Heater Box Starting the Engine 1. Connect the spark plug wire (Figure 20). To install the carburetor heater box, reverse the steps given in Removing the Carburetor Heater Box. Remove the fasteners from their holes before installing the carburetor heater box. Filling the Fuel Tank Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others.
Figure 23 5. Insert the ignition key (Figure 24). Figure 26 Important: To prevent damaging the electric starter, run it no more than 10 times at intervals of 5 seconds on, then 5 seconds off. If the engine does not start after this series of attempts, allow the starter to cool for at least 40 minutes before trying to start it again. If the engine still does not start, take the snowthrower to an Authorized Service Dealer for service. Figure 24 6.
Stopping the Engine Operating Tips 1. Engage the auger to remove any remaining snow from inside the housing. 2. Run the engine for a few minutes to dry off any accumulated moisture. When the snowthrower is in operation, the impeller and auger can rotate and cut off or injure hands and feet. 3. Release the auger/impeller drive control lever and the traction control lever (Figure 13).
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule(s) Maintenance Service Interval After the first hour After the first 2 hours Before each use or daily Maintenance Procedure • Inspect and adjust the traction drive belt. • Inspect and adjust the auger/impeller drive belt. • Change the engine oil. • Check the engine oil level and add oil if necessary. • Inspect and adjust or replace the traction drive belt when necessary.
SG, SH, or SJ. For extremely cold conditions (below 0°F or -18°C), use 0W-30 detergent oil that has the American Petroleum Institute (API) service classification SF, SG, SH, or SJ. Important: Do not overfill the crankcase with oil and run the engine; engine damage will result. Drain the excess oil until the oil level on the dipstick reads Full. 7. Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight. Adjusting the Skids and Scraper Figure 28 1. Auger blade 2.
4. Loosen the flange nuts that secure the selector plate to the control panel (Figure 29). 6. With the drive assembly 1/8 inch (3 mm) from the roll pin, tighten the flange nuts that secure the speed selector plate. 7. Shift the speed selector lever to the R (Reverse) position and back to third gear to check the adjustment. 8. If the space between the roll pin and the drive assembly is more than 3/16 inch (5 mm), repeat steps 3 through 6. 9.
Lubricating the Snowthrower • For temperatures between 0°F and 32°F (-18°C to 0°C), use SAE 5W30 or SAE 10. Service Interval: Every 20 hours • For air temperatures below 0°F (-18°C), use SAE 0W30. Yearly or before storage Lightly lubricate all moving parts of the snowthrower after every 20 operating hours and at the end of the snowthrowing season. 1. Block up the rear of the snowthrower. 2. Remove the left wheel. 3. Clean the area around the oil drain plug (Figure 32).
Figure 35 1. 0.030 inch (0.76 mm) 5. Install the spark plug by hand and then torque it to 15 ft-lb (20.4 N-m). Note: If you do not have a torque wrench, tighten the plug firmly. Figure 34 Adjusting the Traction Drive Belt Important: Do not excessively oil the snowthrower; extra oil may enter the traction drive and cause the traction drive belt to slip. Service Interval: After the first hour Before each use or daily 5. Wipe up any excess oil.

Remove the traction drive belt from the engine pulley and the large traction pulley (Figure 37). 10. Install a new belt around the large traction pulley. Figure 37 1.
18. Check the auger/impeller drive linkage and adjust it if necessary. Refer to steps 4 through 7 of Installing the Auger/Impeller Drive Control Linkage in Setup. Replacing the Auger/Impeller Drive Belt 19. Install the belt cover. If the auger/impeller drive belt becomes worn, oil-soaked, or otherwise damaged, replace the belt. 1. Remove the 2 flange-head bolts that hold the belt cover in place and set the cover aside (Figure 36). 2. Loosen the belt guide (Figure 37). 3.
4. Open the fuel shutoff valve and allow the fuel to drain out of the fuel tank into the drain pan. 11. Pull the recoil starter slowly to distribute the oil on the inside of the cylinder. 5. Install the fuel line onto the fuel shutoff valve and secure it with a hose clamp. 12. Lubricate the snowthrower. Refer to Lubricating the Snowthrower. 6. Connect the wire to the spark plug. 13. Clean the snowthrower. 7. Start the snowthrower and run the engine until it stops.
Troubleshooting Problem Possible Cause Electric starter does not turn (electric-start models only) 1. The power cord is disconnected at the outlet or the snowthrower. 1.
