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.

Operation

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:

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.

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.
