Loosely mount the worm gear and the bracket to the mounting flange with a bolt, a pyramidal washer, and a locknut as shown in Figure 10. 5. To adjust the distance: 4. Slide the worm gear into the teeth of the chute retaining ring and tighten the locknut (Fig. 10). A. Remove the clevis pin. 5. Tighten the locknut that secures the chute control bracket (Fig. 9). B.
8. If the oil level is below the Add mark on the dipstick, slowly pour only enough oil into the filler hole to raise the oil level to the Full mark on the dipstick. Before Starting Filling the Engine Crankcase with Oil 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. The engine comes from the factory with only a few ounces of oil in the crankcase. Before starting the engine, add oil.
Reviewing the Maintenance Schedule Danger When fueling, under certain circumstances, a static charge can develop, igniting the gasoline. A fire or explosion from gasoline can burn you and others and damage property. Review the Recommended Maintenance Schedule on page 17. You may need to perform one or more additional procedures before or soon after you begin operating the snowthrower. • Always place gasoline containers on the ground and away from your vehicle before filling.
• Chute Deflector Handle (Fig. 13)—Move the deflector handle forward to move the snow stream down; move it rearward to move the snow stream up. 2 1 • Fuel Shutoff Valve (Fig. 13)—Close the valve by rotating clockwise. Open the valve by rotating it counterclockwise. Close the valve when you do not use the snowthrower. 3 4 • Choke (Fig. 14)—Move the choke to the (Full) position to start a cold engine. As engine warms up, gradually move the choke to the Off position. m–4516 1 Figure 15 1.

When you insert the axle pins through the holes in the wheel hubs and the inner axle holes (Fig. 4) and engage the traction control lever, the snowthrower propels itself. C. When the engine starts, disconnect the power cord from the snowthrower and the outlet.
• Discharge the snow downwind whenever possible. • If the wheels slip, shift the snowthrower into a lower gear to reduce the forward speed. • Do not overload the snowthrower by clearing snow at too fast a rate. If the engine slows down, shift the snowthrower into a lower gear to reduce the forward speed. • After clearing the snow, let the engine run for a few minutes to prevent moving parts from freezing. Engage the auger/impeller to clear any remaining snow from inside the housing.
Maintenance Service Interval 100 Hours Annually Maintenance Procedure • Inspect and gap the spark plug. Replace it if necessary. Refer to Replacing the Spark Plug on page 23. • Check the auger gearbox grease after removing the snowthrower from storage and add grease if necessary. Refer to Checking the Auger Gearbox Grease on page 18. • Change the engine oil at the end of the snowthrowing season. Refer to Changing the Engine Oil on page 22.

Support the auger blades so that they are 1/8 inch (3 millimeters) off the ground (Fig. 21). 5. Remove the pipe plug from the gearbox (Fig. 19). 3 6. Check the level of grease in the gearbox. The grease should be visible through the opening. 7.
Adjusting the Speed Selector Adjust the speed selector linkage initially and when the snowthrower is slow, first gear has no speed, or the speed selector does not move into third gear. 1. Stop the engine and wait for all moving parts to stop. 2. Disconnect the wire from the spark plug and ensure that the wire does not contact the spark plug (Fig. 16). 3. Tip the snowthrower forward and block it so that it cannot fall. 4.
Replacing the Traction Drive Belt If the traction drive belt becomes worn, oil-soaked, or otherwise damaged, replace the belt. 1 1. Stop the engine and wait for all moving parts to stop. m–2592 2. Disconnect the wire from the spark plug and ensure that the wire does not contact the spark plug (Fig. 16). Figure 26 3. Drain the gasoline from the fuel tank. Refer to Emptying the Fuel Tank on page 24. 1. Flange-head bolts 4.
17. Set the snowthrower upright. 6. If the belt still slips, replace it. Refer to Replacing the Auger/Impeller Drive Belt on page 22. 18. Install the auger/impeller drive belt around the large auger/impeller pulley and engine pulley, ensuring that the belt is on the inside of the idler pulley and the belt guide (Fig. 25). Important Do not operate the snowthrower if the auger and the impeller rotate when you disengage the auger/impeller drive control lever. 19.
4. Remove the left wheel. 5. Clean the area around the oil drain plug (Fig. 28). 1 2 m–4070 887 Figure 29 Figure 28 1. Oil drain plug 2. Drain extension Important Do not excessively oil the snowthrower; extra oil may enter the traction drive and cause the traction drive belt to slip. 6. Slide an oil drain pan below the drain extension and remove the oil drain plug (Fig. 28). 7. Wipe up any excess oil.
Storage 1 Warning 110 Figure 30 Gasoline fumes are highly flammable, explosive, and dangerous if inhaled. If the product is stored in an area with an open flame, the gasoline fumes may ignite and cause an explosion. 1. 0.030 in. (0.76 mm) 7. Install the spark plug by hand and then torque it to 15 ft-lb (20.4 N m). If you do not have a torque wrench, tighten the plug firmly.
2. Clean the snowthrower. Accessories 3. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. You can obtain the following snowthrower accessories from your Authorized Service Dealer: • Tire Chain Kit 4. Tighten any loose fasteners. Repair or replace any damaged parts. • Drift Breaker Kit • Snow Shield Kit 5.
Problem Engine runs rough Engine runs, but the snowthrower discharges snow poorly or not at all Snowthrower does not properly clear the snow off the surface Possible Causes Corrective Action 10.The air temperature is above 40°F (4°C) and the carburetor heater box is on the snowthrower. 10.Remove the carburetor heater box. 1. The choke is in the On position. 1. Move the choke to the Off position. 2. The fuel shutoff valve is not completely open. 2. Open the fuel shutoff valve. 3.
