ASSEMBLY 4. Filling the Engine with Oil ENGINE See engine manual. LUBRICATION NOTE: SAE 10W30 or SAE 5W30 oil is acceptable for use in cold temperatures if engine is difficult to start. NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.

OPERATION Operation Checking the Engine Oil Level NOTE: Determine the left and right sides of the machine from the normal operating position. 1. Move the snowthrower to a level surface. 2. Clean around the dipstick (Figure 9). NOTE: Dipstick location may vary depending on engine type. • Gasoline is extremely flammable and explosive. A fire or explosion from gasoline can burn you and others.
OPERATION Starting the Engine 1. Push key in (Figure 10). 2. Move choke lever to left position. 3. Firmly push in the primer 2 times with your thumb, holding the primer in a for a second before releasing it each time. NOTE: Remove your glove when you push in the primer so that air cannot escape from the primer hole. IMPORTANT: It may not be necessary to 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.
OPERATION Engaging the Auger Blades IMPORTANT: During initial operation there may be wear between the auger blades and the scraper bar. Maximum performance, both snow throwing and driving, occurs when there is zero clearance between these two parts (Figure 15). 1. To engage the auger blades, hold the control bar against the handle (Figure 13). During initial break-in period of the auger blades it is normal for the auger blades to build up excessive heat if not operated in the snow.
OPERATION Adjusting the Discharge Chute and Chute Deflector Clearing a Clogged Discharge Chute 1. To adjust the discharge chute, move deflector chute handle left or right to desired position (Figure 17). Hand contact with the rotating auger blades inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute. 1 3 2 To clear the chute: 1. SHUT THE ENGINE OFF! 2.
OPERATION Preventing Freeze-up After Use • Operating Tips Let the engine run for a few minutes to prevent moving parts from freezing. Stop the engine, wait for all moving parts to stop, and remove ice and snow from the snowthrower. • Clean off any snow and ice from the base of the chute. • Rotate the discharge chute left and right to free it from any ice buildup.
MAINTENANCE Maintenance NOTE: Determine the left and right sides of the machine from the normal operating position.
MAINTENANCE Inspecting the Auger Blades/ Scraper Bar 5. After draining the used oil, return the snowthrower to the operating position. 6. Install the oil drain plug and torque to 145-150 in-lbs (17 N-m). NOTE: Dipstick location may vary depending on engine type. Before each session, inspect the auger blades for wear. When an auger blade edge or the scraper bar has worn down have an Authorized Service Dealer replace the auger blades and the scraper bar (Figure 21). 7.
MAINTENANCE Servicing the Spark Plug 6. Remove two screws in plenum that hold top cover (Figure 26). 7. Remove the oil fill cap. Use a NGK BPR6ES, Champion RN9YC, or BOSCH WR6DC spark plug or equivalent. 1. 2. 3. 4. 5. 2 Move snow thrower to a level surface. Run snow thrower until all fuel has been depleted. Wait until engine is cool. Rotate the discharge chute so that it faces forward.
MAINTENANCE 12. Unplug electrical wires on back of ignition switch (Figure 28). 13. Pull tube off the back of the primer bulb. 2 0.030 inch (0.76 mm) 4 2 4 Figure 30 1 19. Install the spark plug and torque it to 20–22 ft-lb (27–30 N-m). 20. Connect the spark plug wire to the spark plug (Figure 29). 21. Reattach primer bulb tube to primer bulb and electrical wires on back ignition switch of rear upper cover (Figure 28). 22.
MAINTENANCE Replacing the Drive Belt 4. Install the new auger V-belt and drive pulley, routing it as shown in Figure 33. NOTE: Route the new auger v-belt first around the engine pulley, then the idler pulley, and finally around the drive pulley while pressing down on the front of the idler arm. (Figure 33). If auger V-belt becomes worn, oil-soaked, excessively cracked, frayed, or otherwise damaged, replace the belt. 1. Remove the drive side cover by removing the six screws as shown in (Figure 32). 4 5.
STORAGE Storage ENGINE OIL Drain oil (with engine warm) and replace with clean engine oil. (See “Changing the Engine Oil” section of this manual). STORING THE SNOWTHROWER Immediately prepare your snow thrower for storage at the end of the season or if the unit will not be used for 30 days or more. CYLINDER 1. Remove spark plug. 2. Pour one ounce (29 ml) of oil through spark plug hole into cylinder. 3. Pull recoil starter handle slowly a few times to distribute oil.
TROUBLESHOOTING Troubleshooting See appropriate section in manual unless directed to a service center/department. PROBLEM CAUSE CORRECTION Does not start 1. Safety ignition key is not inserted. 1. Insert safety ignition key. 2. Out of fuel. 2. Fill fuel tank with fresh, clean gasoline. 3. ON/OFF switch is OFF. 3. Move ON/OFF switch to ON position. 4. Choke in OFF position. 4. Move to FULL position. 5. Primer not depressed. 5. Prime as instructed in the Operation section of this manual.
