Engine Key Front Gas Tank Area *5 HP Engine- Lower G. Choke Knob Rear Gas Tank Area 6 Controls GROUND SPEED CONTROLS A. Speed Selector - This lever (A, Figures 4 & 5) is used to set the ground speed of the snowthrower. The snowthrower has five forward speeds, 1–5, and two reverse speeds, 1–2. No neutral position or gate is required, since the traction drive design automatically provides "neutral" (no forward or reverse movement), whenever the Drive Control is released. B. Drive Control - This control engages the traction drive as the lever (B, Figures 4 & 5) is depressed, and disengages the traction drive when the lever is released. The traction drive provides power to the wheels. NOTE: Changing ground speeds must only be done while the Drive Control is in the disengaged (fully released) position. AUGER CONTROL C. Auger Control - The Auger Control clutch lever (C Figures 4 & 5), engages the auger drive (which throws the snow) as the lever is depressed, and disengages the auger drive when the lever is released. DEFLECTOR CONTROLS D. Chute Direction Control - The Chute Direction Control (D, Figures 4 & 5), allows the discharge chute to be rotated to throw snow in the desired direction. Snow may be thrown at any angle from straight left, to straight forward, to straight right. E. Chute Deflector - Controls the distance snow is thrown. Tilting the Chute Deflector (E, Figure 5) UP provides a higher stream and greater distance, while tilting the deflector DOWN provides a lower stream and less distance. F. Chute Deflector Knob - This knob (F, Figure 5) allows the discharge Chute Deflector (E, Figure 5) to be locked in the desired tilt position. SCRAPER HEIGHT CONTROL G. Scraper Bar Height Control - The Skid Shoes (G, Figure 5) control the height the scraper bar (located at the bottom of the auger housing). The scraper bar allows smooth surfaces (such as concrete or asphalt driveways) to be scraped clean of snow. On surfaces such as gravel, the scraper bar should be adjusted higher — so that it will not pick up gravel or debris. B A CD Figure 4. Operator's Control Position FRONT A. Speed Selector C.

Traction Lock Pins - The traction drive to each wheel can be locked and unlocked with the Traction Lock Pins (H, Figure 5) to permit the unit to “freewheel,” allowing easier manual handling and transport of the snowthrower. 7 Operation GENERAL OPERATION CHECKS BEFORE EACH START-UP 1. Make sure all safety guards are in place and all nuts, bolts and clips are secure. 2. Check the engine oil level. See your engine Owner’s Manual for procedure and specifications. 3. Check to make sure spark plug wire is attached and spark plug is tightened securely. If necessary, torque spark plug to 15 ft. lbs. 4. Check the fuel supply. Fill the tank no closer than 1/4 to 1/2 inch of top of tank to provide space for expansion. See your engine Owner’s Manual for fuel recommendations. 5. Check the Scraper Bar to make sure it is set at the desired height. Adjust the Skid Shoes if necessary. (See page 10.) 6. Check the Drive Control (B, Figure 1), and Auger Control (C, Figure 1) for proper operation. If adjustment is required, see the Service section (pages 1617) for procedures. 7. Check the Chute Direction Control (D, Figure 1) for proper operation. The discharge chute should rotate freely in both directions. See the Service section for adjustment procedures and troubleshooting. 8. Check the Chute Deflector (E, Figure 1) for proper operation. The deflector should pivot freely up and down when the Chute Deflector Knob is loosened. If adjustment is required, see the Service Section for procedures. 9. Position the chute at the desired starting direction and set the deflector at the desired angle. 10. Check the Speed Selector (A, Figure 1) for smooth operation. The control must move freely into each speed position gate and remain in position when released. If the Speed Selector does not move freely into all forward and reverse speed positions, contact your local authorized dealer for assistance. WARNING To avoid serious injury, do not put your hands into the auger housing or discharge chute. If auger stalls or chute becomes plugged, use the following procedure to remove objects or clear the chute: 1. Release both the Drive and Auger Control levers. 2. Shut off the engine. 3. Remove the Engine Key. 4. Wait for moving parts to stop. 5. Disconnect spark plug wire. 6. Use a narrow board to remove foreign objects and clear the chute or auger. Never put your hands into the a...
