GENERAL OPERATION
Operation - 17
to release pressure from the auxiliary hydraulic
circuit. Disconnect the hydraulic quick couplers
from the power unit and lay the hoses across the
fan belt cover. Do not allow couplers to lay in dirt
or snow.
8. Disconnect the electric plug (if equipped).
9. Disengage the attachment hitch lock*.
10. Restart the power unit and back slowly away from
the snow blower.
Snow Blower Operating Procedure
Before operation, perform daily inspection, verify
weight transfer is set properly, and verify the skid
shoes are set at the desired height.
Move the machine into position to start blowing.
Rotate the discharge chute to the desired direc-
tion and adjust the discharge chute deflector to the
desired angle. Always direct the discharged snow
into open areas. Whenever possible, blow snow with
the wind direction.
With the power unit’s engine running between 2,000
and 2,500 RPM, engage the PTO switch. Adjust the
throttle to the desired engine RPM.
Lower the snow blower to the ground and place
the power unit’s primary S.D.L.A lever in the float
position by pushing it to the right until the detent
engages. The lever will stay in this position until
intentionally removed.
Drive forward slowly while keeping a close watch for
potential hazards. Adjust the discharge chute rotation
and the discharge chute deflector angle as necessary
to keep the discharged snow directed to open areas.
Transport of Snow Blower
Transport the snow blower with the power unit front
hitch and snowblower raised to reduce wear of the
equipment. Travel slowly when transporting over
undulating or rough surfaces to maintain control of
power unit and to reduce the shock to the machine.
Travel slowly when transporting on slippery surfaces.
Always disengage the PTO before transporting the
snow blower.
Discharge Chute Rotation
Move the secondary S.D.L.A. lever to the left or right
and hold in position to rotate the discharge chute.
When the discharge chute is pointed in the desired
direction, release the secondary S.D.L.A. lever to
stop chute rotation.
Discharge Chute Deflector Adjustment
(Manual)
Release the discharge chute adjustment link by pull-
ing to the side. Adjust the discharge chute deflector
to the desired angle. Engage the discharge chute
adjustment link to lock in place.
Discharge Chute Deflector Adjustment
(Optional Actuator Control)
Use the power unit’s momentary switch(es) to adjust
the angle of the discharge chute deflector. Hold the
switch until the discharge chute deflector reaches
the desired angle, then release the switch.
Rear Skid Shoe Adjustment
Skid shoes are provided to keep the cutting edge off
the surface to be cleaned, especially when clearing
snow from gravel driveways or roadways.
The rear skid shoe height is determined by the
placement of spacer washers between the skid shoe
and the skid shoe mount. Extra spacer washers are
stored on top of the skid shoe mount.
Determine the number of spacer washers that need
to be moved to reach the desired skid shoe height.
When making adjustments with the snow blower
in the raised position, the snow blower must be
supported securely with blocks or jack stands.
Hydraulic drift or accidental release of hydraulic
pressure could allow the snow blower to lower
and trap a person or appendage, if the snow
blower is not securely supported.
Raise the snow blower to the highest position and
support securely with blocks or jack stands.
Remove the lynch pin (A) and the spacer washers (B)
from the top of the skid shoe mount.
