Plow Assembly 21
Handle Pinned With Plow on Truck DWG NO. 5691
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 posi-
tion 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 speci-
fication 5606, for plowing in extremely cold
temperatures.
Pour hydraulic oil into the power unit oil
reservoir until the reservoir is half full.
Angle the plow full left or right with the
cab control box inside the truck to fill the
angling cylinder with oil. Add more oil un-
til the reservoir is about 3/4 full. Do not
over-fill the reservoir.
Cycle the plow left and right and up and
down to purge any air trapped in the hy-
draulic system.
NOTE: New hydraulic cylinders will leak a small
amount of oil until packings become saturated
and produce a good seal. If leakage is exces-
sive, or if leaking continues after initial cycling,
tighten the cylinder packing nut in 1/8-turn in-
crements until leaking stops.
22. Fasten the power unit cover onto the lift
frame bracket with two 1/4” x 3/4” carriage
bolts, flat washers 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.
DWG NO. 6587
When the cover is closed, rods from the
latch handles should extend behind the
light brackets to hold the cover in place.
23. Assemble side markers on the ends of the
moldboard with 5/16 inch bolts, flat washers
and lock nuts.
