Note: Use only a UL-listed, 16-gauge extension cord recommended for outdoor use that is not longer than 15 m (50 feet). WARNING Figure 14 The electrical cord can become damaged, causing a shock or fire. 1. Symbols on the choke lever indicating to pull out the choke lever to activate the choke. 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.
PAGE 10
Disengaging the Rotor Blades CAUTION If you leave the machine plugged into a power source, someone can inadvertently start the machine and injure people or damage property. To disengage the rotor blades, release the control bar (Figure 19). Unplug the power cord whenever you are not starting the machine. Engaging the Rotor Blades To engage the rotor blades, hold the control bar against the handle (Figure 18).
PAGE 11
Clearing a Clogged Discharge Chute moving the control up the handle rotates the discharge chute to the right (Figure 21). WARNING Hand contact with the rotating rotor blades inside the discharge chute is the most common cause of injury associated with machines. Never use your hand to clean out the discharge chute. To clear the chute: • Shut the engine off ! • Wait 10 seconds to be sure the rotor blades have stopped rotating. • Always use a cleanout tool, not your hands.
PAGE 12
• With the ignition key in the Off position, pull the recoil starter handle several times or connect the electrical cord to a power source and the machine and push the electric start button once to prevent the recoil starter and/or the electric starter from freezing up. • In snowy and cold conditions, some controls and moving parts may freeze. Do not use excessive force when trying to operate frozen controls.

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 28). Figure 30 Figure 28 4.

10. Remove the spark plug from the cylinder head. Important: Replace a cracked, fouled, or dirty spark plug. Do not clean the electrodes because grit entering the cylinder can damage the engine. 11. Set the gap on the plug to 0.030 inch (0.76 mm) (Figure 34). Figure 32 1. Fuel tank cap 4. Small screw 2. Large screws (3) 5. Chute seal Figure 34 1. Center electrode insulator 3. Discharge chute 3.

Note: The small screw goes through the small hole in the chute seal at the front of the discharge chute opening. Note: Route the new drive belt first around the engine pulley, then the idler pulley, and finally around the loose rotor pulley positioned just above the rotor shaft (Figure 36). Replacing the Drive Belt 6. Install the rotor pulley onto the rotor shaft (Figure 36). If drive belt becomes worn, oil-soaked, excessively cracked, frayed, or otherwise damaged, replace the belt. 1.
