Product Overview • Thoroughly inspect the area where you will use the machine, and remove all doormats, sleds, boards, wires, and other foreign objects. • If a shield, safety device, or decal is damaged, illegible, or missing, repair or replace it before beginning operation. Also tighten any loose fasteners. DANGER Fuel is extremely flammable and explosive. A fire or explosion from fuel can burn you and others.
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—Check the engine-oil level and add oil if necessary. • 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.

Adjusting the Discharge Chute and Chute Deflector To adjust the discharge chute, move the chute handle and the chute-deflector handle as shown (Figure 19). g219303 Figure 16 Disengaging the Rotor Blades g001128 Figure 19 1. Chute handle To disengage the rotor blades, release the control bar (Figure 17). 2. Chute-deflector handle Clearing a Clogged Discharge Chute To clear the chute: • Shut the engine off! • Wait 10 seconds to ensure that the rotor blades have stopped rotating.

on the handle, but allow the machine to work at its own pace. 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. • When storing the machine for more than 30 days, refer to Storage (page 16) 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 21). g011232 Figure 22 g006402 Figure 21 1. Adjuster link 3. Spring cover 2. Z-fitting 4. Unhook the spring here. 1. Upper end of spring 3. Pivot point 2. Insert the upper end of spring into this hole 4. Remove the upper end of spring from this hole Note: The belt may slip (squeal) in wet conditions; to dry out the drive system, start the rotor and run it without a load for 30 seconds.
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 27). 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 by removing the 3 screws holding the chute and the screws holding the chute seal (Figure 28). g011435 Figure 29 1. Screw (4) 3. Spark plug 2. Shroud 4. Spark-plug wire 5.
PAGE 15
12. Install the spark plug and torque it to 20 to 22 ft-lb (27 to 30 N-m). 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 31. 1. Remove the drive-belt cover by removing the 3 bolts as shown in Figure 32. g011440 Figure 31 1. Breather tube g008238 2.
PAGE 16
Storage 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 32). 6. Install the rotor pulley onto the rotor shaft (Figure 32). 7. Install the curved washer and the rotor-pulley bolt and tighten them securely (Figure 32). Storing the Machine WARNING Fuel fumes are highly flammable, explosive, and dangerous if inhaled.

12. With the ignition key in the OFF position, pull the recoil-start handle slowly to distribute the oil on the inside of the cylinder. 13. Clean the machine. 14. Touch up chipped surfaces with paint available from an Authorized Service Dealer. Sand affected areas before painting, and use a rust preventative to prevent the metal parts from rusting. 15. Tighten any loose fasteners. Repair or replace any damaged parts. 16.
