2 3 Installing the Discharge Chute Filling the Engine with Oil Parts needed for this procedure: No Parts Required 1 Discharge chute 1 Chute handle 3 Phillips head bolts 3 Washers 3 Locknuts Procedure Your machine does not come with oil in the engine, but it does come with a bottle of oil. Important: Before starting the engine, fill the engine with oil. Note: The bottle of oil may contain an ounce or two more than the engine requires. Do not overfill or under fill the engine.
PAGE 7
Product Overview 3. Unscrew the oil fill cap and remove it. 4. With the machine in the operating position, carefully pour oil into the crankcase. Wait 3 minutes for the oil to settle and add enough to bring it to the point of overflow. There should be very little, if any, oil left in the bottle. 2 Note: You may tip the machine forward (handle up) to make adding oil easier. Remember to return the machine to the operating position before checking the oil level.
PAGE 8
Filling the Fuel Tank • For best results, use only clean, fresh, unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). • Oxygenated fuel with up to 10% ethanol or 15% MTBE by volume is acceptable. • Do Not use ethanol blends of gasoline (such as E15 or E85) with more than 10% ethanol by volume. Performance problems and/or engine damage may result which may not be covered under warranty. Figure 12 • Do Not use gasoline containing methanol. 1.

Figure 17 Figure 14 Note: Use only a UL-listed, 16-gauge extension cord recommended for outdoor use that is not longer than 50 feet (15 m). 1. Choke lever WARNING The electrical cord can become damaged, causing a shock or fire. Figure 15 Thoroughly inspect the electrical cord before plugging it into a power source. If the cord is damaged, do not use it to start the machine. Replace or repair the damaged cord immediately. Contact an Authorized Service Dealer for assistance. 1.

Preventing Freeze-up after Use • 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 machine. • 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.
PAGE 12
• If the machine does not propel itself forward on slippery • Overlap each swath to ensure complete snow removal. surfaces or in heavy snow, push forward on the handle, but allow the machine to work at its own pace. • Discharge the snow downwind whenever possible. Maintenance Note: Determine the left and right sides of the machine from the normal operating position.

Adjusting the Control Cable Checking the Control Cable Service Interval: After the first hour—Check the control cable and adjust it if necessary. Yearly—Check the control cable and adjust it if necessary. Move the control bar back toward the handle to remove the slack in the control cable (Figure 25). Figure 26 1. Adjuster link 3. Spring cover 2. Z-fitting 4. Unhook the spring here. Note: You can pull up the adjuster link and cable to make unhooking the spring easier. 2.
PAGE 14
Changing the Engine Oil Service Interval: After the first 2 hours Yearly Run the engine a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants. 1. Siphon the fuel from the fuel tank into an approved fuel container, or run the engine until it stops. 2. Move the machine to a level surface. 3. Place an oil drain pan under the oil drain plug, remove the oil drain plug, and tip the machine backward and drain the used oil in the oil drain pan Figure 29).
