Important days old. Important Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol. Do not use gasoline that is more than 30 Danger 1. Clean around the fuel tank cap (Fig. 12). 2. Remove the fuel tank cap. In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. 3.

Fully engage the traction drive lever to move the wheels into the alternate position (Figs. 22 and 23). Note: When shifting, you may need to slightly raise the handle assembly to assist the wheel movement. Operating the Differential For maximum maneuverability, leave the differential in the unlocked position. When you need additional traction, shift the differential to the locked position.
• Always use the Fast throttle position when throwing snow. • Unlocked position—Slide the coupling lock spring into the right-hand shaft groove (Fig. 25). • Overlap each swath to ensure complete snow removal. Note: When sliding the coupling from the unlocked to the locked position, you may need to swivel the snowthrower slightly to allow the coupling to clear the differential body bolt heads. • Discharge the snow downwind whenever possible.
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. Refer to Checking the Auger Gearbox Oil Level on page 19. • Adjust the skids and the scraper.2 Refer to Adjusting the Skids and the Scraper on page 19.
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 2. Move the snowthrower to a level surface. 3. Disconnect the wire from the spark plug and ensure that the wire does not contact the spark plug (Fig. 12).
1. Loosen the upper jam nut that secures the traction cable to the mounting bracket (Fig. 28). 5. Loosen the four flange bolts that secure both skids to the auger side plates (Fig. 10) until the skids slide up and down easily. 6. Support the auger blades so that they are at least 1/8 inch (3 millimeters) off the ground (Fig. 27). 4 1 2 3 183 Figure 28 1 2 3 1. Jam nut 2. Mounting bracket 3.

5. Hold the lever and insert a 0.010 in. (0.25 mm) feeler gauge between a coil in the center of the spring (Fig. 29). Danger Improperly adjusting the auger/impeller drive belt may cause injury if the auger/impeller continues to turn after you release the control lever. A rotating impeller or auger can cut off or injure fingers or hands. • Keep your face, hands, feet, and any other part of your body or clothing away from moving or rotating parts. • Maintain the proper impeller brake arm clearance.
3. Remove the three flange-head bolts that secure the belt cover to the engine frame and slide the belt cover and the cable cover up the cables (Fig. 5). 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 plug (Fig. 32). 4. Move the speed shift control to the N (Neutral) position. 1 5. Remove the two-flange bolts that secure the idler pulley assembly to the engine frame and remove idler pulley assembly (Fig.
Lubricating the Drive Chain 8. If the deflection is not between 1/8 and 3/8 in. (3 and 10 mm), go to step 9; otherwise, return the snowthrower to its upright position. Lightly lubricate the drive chain after every 15 operating hours and at the end of the snowthrowing season. 9. Loosen the four flange-head bolts (two on each side) that secure the transmission frame to the engine frame (Figs. 36 and 37). 1. Disconnect the wire from the spark plug and ensure that the wire does not contact the plug (Fig.
Replacing the Spark Plug 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). Use a Champion RN4C or equivalent spark plug. Install a new plug after every 100 operating hours. 1. Stop the engine and wait for all moving parts to stop. 6. Open the fuel shutoff valve and allow the fuel to drain out of the fuel tank into the drain pan. 2. Clean any debris from around the base of the spark plug. 7.
3. Use an oil can to squirt two teaspoons of oil into the spark plug hole. 4. Cover the snowthrower and store it in a clean, dry place out of the reach of children. Allow the engine to cool before storing it in any enclosure. 4. 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. Do not connect the wire to the plug. Accessories 5. Pull the recoil starter slowly to distribute the oil on the inside of the cylinder.
Problem Engine runs rough Engine runs, but the snowthrower discharges snow poorly or not at all Possible Causes Corrective Action 7. The spark plug is pitted, fouled, or the gap is incorrect. 7. Check the spark plug and adjust the gap if necessary. Replace the spark plug if it is pitted, fouled, or cracked. 8. The fuel cap vent is restricted. 8. Remove the vent restriction or replace the fuel cap. 9. The engine oil level in the engine crankcase is too low or too high. 9.
Problem Snowthrower does not properly clear the snow off the surface Possible Causes Corrective Action 6. The auger/impeller drive belt is loose or is off the pulley. 6. Install and/or adjust the auger/impeller drive belt. 7. The auger/impeller drive belt is worn or broken. 7. Replace the auger/impeller drive belt. 1. The tire pressure is low. 1. Check the pressure in the tires and adjust it if necessary. 2. The skids and/or the scraper is not properly adjusted. 2.
