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 expan- sion. See your engine Owner’s Manual for fuel rec- ommendations.

5.Check the Scraper Bar to make sure it is set at the desired height. Adjust the Skid Shoes if necessary. (See page 11.)

6.Check the Drive Control (B, Figure 6), and Auger Control (C, Figure 6) for proper operation. If adjust- ment is required, see the Service section for proce- dures.

7.Check the Chute Direction Control (D, Figure 6) 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 7) 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 6) 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 auger or discharge chute.

WARNING

For your safety, operation on slopes should be in an up and down direction only. If it becomes necessary to move across the face of a slope, use caution and do not blow snow. Be very careful when changing direction on a slope.

Proper winter footwear is recommended for the operator to help prevent slipping. Never attempt to clean snow from excessively steep slopes. The maximum slope for any operation is 17.7% (10º).

WARNING

Gasoline is highly flammable and must be handled with care. Never fill the tank when the engine is hot or running. Always move outdoors to fill the tank. Keep snowthrower and gasoline away from open flame or spark.
