CONGRATULATIONS on your purchase of a new snow thrower. It has been designed, engineered and manufactured to give best possible dependability and performance. Should you experience any problem you cannot easily remedy, please contact your nearest authorized service center. We have competent, well-trained technicians and the proper tools to service or repair this unit. Please read and retain this manual. The instructions will enable you to assemble and maintain your snow thrower properly.
Operation Maintenance and Storage 1. Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times. 2. Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden hazards or traffic. 3. After striking a foreign object, stop the engine (motor), disconnect the cord on electric motors, thoroughly inspect the snow thrower for any damage, and repair the damage before restarting and operating the snow thrower. Remove key.

Product Overview 3. 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. 13 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 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 8). 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.
Starting the Engine 3. Firmly push in the primer 2 times with your thumb, holding the primer in a for a second before releasing it each time (Figure 11). 1. Push key in (Figure 9). 1 1 Figure 11 1. Key 1. Primer Figure 9 NOTE: Remove your glove when you push in the primer so that air cannot escape from the primer hole. 2. Move choke lever to left position (Figure 10). IMPORTANT: It may not be necessary to use the primer or the choke if the engine has been running and is hot.
Engaging the Auger Blades NOTE: Use only a UL-listed, 16-gauge extension cord recommended for outdoor use that is not longer than 50 feet (15 m). 1. To engage the auger blades, hold the control bar against the handle (Figure 14). The electrical cord can become damaged, causing a shock or fire. Thoroughly inspect the electrical cord before plugging it into a power source. If the cord is damaged, do not use it to start the snowthrower. Replace or repair the damaged cord immediately.
Adjusting the Discharge Chute and Chute Deflector IMPORTANT: During initial operation there is wear between the auger blades and the scraper bar. This wear is normal and to be expected. Maximum performance, both snow throwing and driving, occurs when there is zero clearance between these two parts. In order to account for part variation a small interference is designed into the parts so they can wear to zero clearance within the first few minutes of operation (Figure 16). 1.
Clearing a Clogged Discharge Chute Preventing Freeze-up After Use 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. • 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.
Maintenance NOTE: Determine the left and right sides of the machine from the normal operating position.
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. 7. Clean around the oil filler cap/dipstick (Figure 24). 8. Unscrew and remove the oil fill cap/dipstick. Before each session, inspect the auger blades for wear.
Servicing the Spark Plug 7. Install the oil fill cap. 8. Disconnect the spark plug wire from the spark plug (Figure 28). Use a NGK BPR6ES, Champion RN9YC, or BOSCH WR6DC spark plug or equivalent. 1. Stop the engine and wait for all moving parts to stop. 2. Rotate the discharge chute so that it faces forward. 3. Remove the discharge chute and the discharge chute handle by removing the three carriage bolts and three flange nuts (Figure 26). 1 1 3 Figure 28 1. Spark plug wire 3 9.
Replacing the Drive Belt 4. Install the new drive belt, routing it as shown in Figure 31. NOTE: Route the new drive 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 31). 5. Install the drive side cover with the screws removed in step 1. 3 2 1 If drive belt becomes worn, oil-soaked, excessively cracked, frayed, or otherwise damaged, replace the belt. 1.
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 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. Loss of power 6.
