20. At this point, the mount kit should be assem-
bled onto the truck.
Prongs from the truck mount kit should be at
a height that will slightly lift the plow frame
when attaching the plow. Prong receivers
on the plow frame should be parallel to the
ground when attaching the plow. Apply pow-
ered graphite on the truck prongs to help the
plow to slide on and off more easily.
Handle Pinned With Plow on Truck
Attach the plow onto the truck by driving the
truck prongs into the receivers on the plow
frame.
Pull the latch handle into the frame clevis
to move sliders through the notches in the
prongs and receivers. Pin the handle in the
clevis with its klik pin.
Raise the parking stand to its highest position
and repin.
Connect the two electrical cables from the
plow to their corresponding receptacles on
the truck.
Select Hiniker Cold Flow Hydraulic Oil or an
equivalent oil that meets military specification
5606 for plowing in extremely cold tempera-
tures.
Pour hydraulic oil into the power unit oil res-
ervoir until the reservoir is half full. Angle the
plow full left or right to fill the angling cylinders
with oil, then add more oil until the oil reaches
the fill line - about 1 1/4 inches from the top.
Do not overfill the oil reservoir.
NOTE: New hydraulic cylinders will leak a small
amount of oil until packings become saturated and
produce a good seal. If leakage is excessive, or if
leaking continues after initial cycling, tighten the
cylinder packing nut in 1/8-turn increments until
leaking stops.
21. Fasten the power unit cover to the lift frame
DWG NO. 6721A
Cycle the plow left and right and up and down
to purge any air trapped in the system.
Check the oil level with the plow on the
ground. Add oil to the fill line, if necessary, but
do not overfill the reservoir.
bracket with two 1/4" x 3/4" screws, flat wash-
ers and lock nuts from the hardware bag in
the parts box. Tighten the lock nuts so that
the assembly is secure, yet the cover hinges
freely.
When the cover is closed, rods from the
latch handles should extend behind the
light brackets to hold the cover in place.
