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 18. 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.
• Auger/Impeller Lockup—When you press both the auger/impeller drive control lever and traction control lever, the traction control lever locks the auger/impeller drive control lever down. Release the traction control lever to release both levers. • Chute Deflector Handle (Fig. 16)—Move the deflector handle forward to move the snow stream down and rearward to move the snow stream up. 1 • Ignition Switch (Fig. 14)—Insert the key before starting the engine. To stop the engine, remove the key.
5. Lift the carburetor heater box up and away from the engine. Important Do not use the primer or the choke if the engine has been running and is hot. Excessive priming may flood the engine and prevent it from starting. 6. Disconnect the green ground wire clip under the throttle (Fig. 19). 7. Cover the hole in the center of the primer (Fig. 14) with your thumb and slowly push in the primer 3 times, pausing a moment between pushes. 8. Grasp the recoil starter handle (Fig.
Stopping the Engine 3. Fully engage the traction drive lever to move the wheels into the alternate position (Figs. 21 and 22). 1. Engage the auger to clear any remaining snow from inside the housing. Note: When shifting, you may need to slightly raise the handle assembly to assist the wheel movement. 2. Run the engine for a few minutes to dry off any accumulated moisture. 3. Release the auger/impeller drive control lever and the traction control lever (Fig. 13). 4.
Adjusting the Headlight Warning 1. Loosen the 2 nuts on the U-bolt that hold the headlight bracket to the handle (Fig. 24). The auger/impeller may pick up and throw stones, toys, and other foreign objects, causing serious personal injury to the operator or to bystanders. • Keep the area to be cleared free of all objects that could be picked up and thrown by the auger/impeller. • Keep all children and pets away from area of operation. 5 • Adjust the skids to match the type of surface being cleaned.
Maintenance Note: Determine the left and right sides of the machine from the normal operating position. Recommended Maintenance Schedule Maintenance Service Interval Initially • Check the engine oil level.1 Refer to Checking the Engine Oil Level on page 19. • Check the auger gearbox oil level and add oil if necessary.

Caution If you leave the wire on the spark plug, someone could accidently start the engine and seriously injure you or other bystanders. Disconnect the wire from the spark plug before you do any maintenance. Set the wire aside so that it does not accidentally contact the spark plug. Checking the Engine Oil Level Checking the Auger Gearbox Oil Level Every time you use the snowthrower, first ensure that the oil level is between the Add and the Full marks on the dipstick.
8. Install the pipe plug in the gearbox. For Concrete and Asphalt Surfaces: 9. Connect the wire to the spark plug. If the snowthrower does not clear the snow close enough to the pavement, adjust the skids to lower the scraper; if the pavement surfaces are cracked, rough, or uneven, adjust the skids to raise the scraper.
7. Repeat steps 4 through 6. Note: The snowthrower should begin to move forward when you press the traction control lever about halfway down toward the handgrip. 8. Check the impeller brake arm clearance by releasing the auger/impeller drive control lever. 5. Stop the engine and repeat steps 1 through 4 until you achieve the proper adjustment. Note: With the lever released, there should be at least 1/8 inch (3 mm) clearance between the tab on the impeller idler arm and the brake arm (Fig. 30).
Replacing the Drive Belts 9. If you need to replace the traction drive belt, slide the middle pulley section and the belt off the crankshaft, and remove the belt from the pulley (Fig. 31). If the auger/impeller drive belt or the traction drive belt (Fig. 31) becomes worn, oil-soaked, or otherwise damaged, replace the belt. 4 5 7 8 6 10. Remove the traction drive belt from the lower traction pulley. 9 11.
Changing the Engine Oil Change the engine oil after the first 2 operating hours, after every 25 operating hours, and at the end of the snowthrowing season. If possible, run the engine just before changing the oil because warm oil flows better and carries more contaminants. 1 1. Stop the engine and wait for all moving parts to stop. 181 2. Disconnect the wire from the spark plug and ensure that the wire does not contact the plug (Fig. 25). Figure 33 1. Drive chain 3.
Replacing the Spark Plug 8. If the deflection is not between 1/8 and 3/8 inch (3 and 10 mm), go to step 9; otherwise, return the snowthrower to its upright position. Use a Champion RN4C or equivalent spark plug. Install a new plug after every 100 operating hours. 9. Loosen the 4 flange-head bolts (2 on each side) that secure the transmission frame to the engine frame (Figs. 35 and 36). 1. Stop the engine and wait for all moving parts to stop. 2. Clean any debris from around the base of the spark plug.
Preparing the Engine 5. Loosen the hose clamp that secures the fuel line to the valve and slide the fuel line off the fuel shutoff valve (Fig. 15). 1. While the engine is still warm, change the engine oil. Refer to Changing the Engine Oil on page 23. 6. Open the fuel shutoff valve and allow the fuel to drain out of the fuel tank into the drain pan. 2. Remove the spark plug. 7. Install the fuel line onto the fuel shutoff valve and secure it with a hose clamp. 3.
