Product Overview Operation Note: Determine the left and right sides of the machine from the normal operating position. Before Operation Before Operation Safety • For electric-start models only: Use extension cords and receptacles as specified in the manual. Thoroughly inspect the electrical cord before plugging it into a power source. If the cord is damaged, do not use it. Replace the damaged cord. Unplug the power cord whenever you are not starting the machine.
PAGE 6
Filling the Fuel Tank Checking the Engine-Oil Level • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method). Service Interval: Before each use or daily • 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.
PAGE 7
Starting the Engine During Operation 1. During Operation Safety Turn the ignition key clockwise to the ON position (Figure 10). • Shut off the engine before unclogging the machine and always use a stick or the snow-cleanout tool (if provided). • A rotating auger can injure hands or feet. Stay behind the handles and away from the discharge opening while operating the machine. Keep your face, hands, feet, and any other part of your body or clothing away from moving or rotating parts.

g006453 Figure 13 g006455 Figure 15 Note: Remove your glove when you push in the primer so that air cannot escape from the primer hole. Important: Run the electric starter no more than 10 times at intervals of 5 seconds on, then 5 seconds off. Running the electric starter extensively can overheat and damage it. If the engine does not start after this series of attempts, wait at least 40 minutes to allow the starter to cool before attempting to start it again.

Engaging the Rotor Blades To engage the rotor blades, hold the control bar against the handle (Figure 16). g011433 Figure 18 Adjusting the Discharge Chute and Chute Deflector g216251 Figure 16 To adjust the discharge chute, press the trigger of the Quick Shoot™ control on the right side of the handle and move it up or down along the handle. Moving the control down the handle rotates the discharge chute to the left; moving the control up the handle rotates the discharge chute to the right (Figure 19).
PAGE 10
After Operation After Operation Safety • Never store the machine with fuel in the fuel tank inside a building where ignition sources are present, such as hot water heaters, space heaters, or clothes dryers. Allow the engine to cool before storing in any enclosure. g006398 Figure 20 1. Chute-deflector trigger • When storing the machine for more than 30 days, 2. Chute deflector refer to Storage (page 18) for important details.

Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval After the first hour After the first 2 hours Before each use or daily Yearly Yearly or before storage Maintenance Procedure • Check the control cable and adjust it if necessary. • Check for loose fasteners and tighten them if necessary. • Change the engine oil. • Check the engine-oil level and add oil if necessary. • Check the control cable and adjust it if necessary.
PAGE 12
Adjusting the Control Cable 1. Slide up the spring cover and unhook the spring from the adjuster link (Figure 22). g006587 Figure 23 g006402 Figure 22 1. Adjuster link 3. Spring cover 2. Z-fitting 4. Unhook the spring here. 4. Check the adjustment; refer to Checking the Control Cable (page 11). 4. Upper end of spring Inspecting the Rotor Blades Service Interval: Yearly—Inspect the rotor blades and have an Authorized Service Dealer replace the rotor blades and scraper if necessary.
PAGE 13
Changing the Engine Oil 8. Service Interval: After the first 2 hours Yearly With the machine in the operating position, carefully pour oil into the oil-fill hole to the point of overflow (Figure 28). 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. If possible, run the engine for a few minutes before changing the oil to warm it. Warm oil flows better and carries more contaminants.
PAGE 14
Servicing the Spark Plug Service Interval: Yearly—Service the spark plug and replace it if necessary. Use a NGK BPR6ES or Champion RN9YC spark plug or equivalent. 1. Shut off 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, the discharge-chute handle, and the chute seal by removing the 3 large screws and 1 small screw (Figure 29). g011435 Figure 30 g006489 Figure 29 1. Fuel-tank cap 4. Small screw 2.
PAGE 15
12. Install the spark plug and torque it to 27 to 30 N∙m (20 to 22 ft-lb). 13. Connect the wire to the spark plug. Replacing the Drive Belt If the drive belt becomes worn, oil-soaked, excessively cracked, frayed, or otherwise damaged, replace the belt. Note: Ensure that the breather tube is routed above the spark-plug wire as shown in Figure 32. 1. Remove the drive-belt cover by removing the 3 bolts as shown in Figure 33. g011440 Figure 32 1. Breather tube g008238 2.
PAGE 16
Adjusting the Quick Shoot Control 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 33). 6. Install the rotor pulley onto the rotor shaft (Figure 33). 7. Install the curved washer and the rotor-pulley bolt and tighten them securely (Figure 33).

4. Hold the discharge chute in the straight-ahead position, pull the lower cable casing downward until you remove the slack in the cable, and tighten the screw on the lower cable clamp securely (Figure 39). g006405 Figure 37 1. Arrows 3. Rotate the discharge chute so that it faces straight ahead and the arrow on the back of the discharge chute aligns with the arrow on the shroud (Figure 38). g006512 Figure 39 1. Lower cable casing 5.
