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.

Disengaging the Rotor Blades Note: If you pull the recoil handle and feel no resistance, the starter may be frozen. Thaw out the starter before attempting to start the machine. To disengage the rotor blades, release the control bar (Figure 20). 5. While the engine is running, push in the choke lever slowly. 6. Unplug the extension cord from the power source and the machine (model 38452 only).

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. Figure 22 1.
PAGE 12
Operating Tips • Remove the snow as soon as possible after it falls. • If the machine does not propel itself forward on slippery surfaces or in heavy snow, push forward on the handle, but allow the machine to work at its own pace. WARNING The rotor blades can throw stones, toys, and other foreign objects and cause serious personal injury to the operator or to bystanders. • Overlap each swath to ensure complete snow removal.

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).
