SAFETY
Safety 3
This is a safety alert symbol. It alerts
an operator to information concern-
ing personal safety. Always observe
and heed these symbols and instructions,
otherwise death or serious injury can result.
Operator safety is a principle concern in equipment design and distribution. However, many
accidents occur because a few seconds of
thought, and a more careful approach to handling, were ignored.
Accidents can be avoided by knowing and following the precautions cited in this manual.
GENERAL SAFETY
1. Read this manual thoroughly. Make sure
the operator understands it and knows
how to operate this equipment safely. This
equipment can kill or injure an untrained or
careless operator and bystanders. If you
sell this equipment, ensure the new owner
acknowledges receipt of this manual.
2. This plow is intended for plowing snow
only. Plowing gravel, rocks, etc., or using
the plow for any purpose other than plowing snow could result in harm to the operator or bystanders or cause damage to the
plow or vehicle, and will void the warranty.
BEFORE OPERATION
1. Discipline yourself to visually check for
worn, damaged or cracked parts before
starting use. Replace these with genuine
Hiniker parts.
2. Escaping hydraulic oil under pressure can
penetrate the skin, causing serious injury.

especially away from blind areas of the operator, before starting, actuating hydraulics
or operating this equipment.
3. Do not service or otherwise handle a plow
in the raised position unless it is securely
blocked against unexpected falling.
4. Do not attempt to handle or service this
equipment, or direct others to do the same,
unless you know how to do it safely and
have the proper tools for the job.
5. Keep hands, feet, hair, and clothing away
from moving parts.
6. Do not alter the equipment to the extent of
compromising safety or performance.
3. Do not plow snow at excessively high
speeds.

falling forward.
4 Operating Procedures
OPERATING PROCEDURES
ATTACHING THE PLOW
Attachment prongs on the truck should be mounted such that the bottom edge of the prongs measure about 10 inches above the ground. Prong
receivers on the plow frame should remain parallel to the ground and at the correct height by
fully retracting the lift cylinder with the upper lift
links and bracing the frame with the stop plate
before removing the plow from the truck (See
“Removing the Plow”). Ideally, the prongs on
the truck should lift the plow frame slightly when
driving into the plow for attachment.
Handle Pinned With Plow On Truck DWG NO. 5691
Powdered graphite applied on the prongs will
help the plow slide on and off more easily.
Check that prongs are in line with the receivers
before slowly driving into the plow. Set the parking brake in the truck to prevent it from creeping
back out from the receivers.
DWG NO. 5690
Pin the handle in the clevis with its klik pin.
Failure to pin the handle in place may allow the
plow to fall off the truck.
NOTE: Before connecting the plow’s wiring to
the truck, make sure power is switched “Off” on
the joystick controller.
Plug in the two electrical connectors between
the plow and the truck after latching the plow.
The alignment tab on the 10-pin receptacle will
mate with the slot in the mounting plate on the
truck grill to ensure proper connection.
Remove the tab lock pin from the indexing hole
and raise the parking stand to its highest position. Repin the stand lever to the front hole in
the push frame for transport.
Pull the latch handle into the clevis on the lift
frame to force the sliders through the notches in
the prongs and receivers. Check that both sliders are fully engaged.
Alignment Tab and Slot DWG NO. 3922
Check that the plow headlamps and turn signals
are operational, and headlamps are aimed correctly. Test the lift and angling cylinders in a safe
area before using the plow.
Operating Procedures 5
Activate high beam/low beam and turn signal/parking lamps from the truck as you normally would
without the plow attached.
To make alignment of the plow easier in the future,
mark a point on the back of the headlamp, a point
on the hood near the front of the truck and a point
on the windshield that are in line when you are
seated behind the steering wheel. Line up these
three points when driving into the plow.
THE JOYSTICK CONTROLLER
The joystick control box has slide switches for controlling power to the snowplow and for switching
from the truck headlights to the headlights on the
plow.
The joystick controller raises and lowers the plow
and angles the blade left or right.
NOTE: Drawings 4176 and 4177 show the raise
and lower functions of the joystick controller as
received from the factory. Functions may be reversed to suit the preference of the operator by
following the instructions on page 22 for switching
the controller joystick and face plate.
The vehicle’s electrical power must be turned on
before the control box will function.
NOTE: When removing the plow, remember to
place the headlight switch in the “truck” position to
return power to the truck’s headlights.
Raise or lower the plow by moving the joystick to
the “raise” or “lower” position.
Hold the plow at an intermediate height by releasing the controller from the “raise” position when the
plow reaches the desired height.
Moving the controller to the “lower” position will
lower the blade to the ground and allow the plow to
“oat” along the contour of the ground while plowing snow.
A yellow light on the control box indicates the plow
is in the oat mode. Momentarily moving the joystick to the “raise” position will remove the plow
from the oat condition and the yellow indicator will
return to green.
Move the joystick left or right to angle the blade.
Release the joystick when the blade is at the desired angle.
TRANSPORTING THE PLOW
Joystick Control Box DWG NO. 4176
Place the on/off switch on the joystick control box
in the “on” position to supply power to the snowplow. A green light will indicate power is on.
Move the headlight slide switch on the control box
to the “plow” position to change from the truck
lights to the snowplow lights.
The extra weight of the snowplow on your truck
will impair handling response and increase braking
distance. The plow will also block some airow to
the vehicle’s cooling system, possibly causing the
vehicle to overheat. Therefore, it is important not
to exceed speeds above 45 mph when the plow is
attached.
Remove the plow if you must drive your truck for
long distances when the temperature is warm.
Raise the blade to a position where it will not interfere with the headlights before driving.
Transport the plow with power to the joystick control box switched off to prevent accidental lowering
of the plow.
Never adjust the blade height or angle the blade
while driving.
6 Operating Procedures
PLOWING SNOW
WARNING: Always wear a seat belt
when plowing snow. Sudden contact
with a hidden object can result in seri-
ous personal injury.
Inspect areas to be plowed before snowfall for
potential hazards, and mark obstructions with
stakes that will be seen when snow covers the
ground. Identify any emergency equipment and
utility outlets that may need to be cleared in the
event of a storm. Prepare a plan beforehand for
clearing snow from tight or enclosed areas and
locate sites for stacking snow.
When using skid shoes on the back of the moldboard, adjust the skids according to the surface
to be plowed. The bottom of the skids should be
about 1/2” below the cutting edge when plowing gravel roads or lots. Skids should be even
with the cutting edge on hard surfaces such as
asphalt or concrete.
Always plow snow as it is accumulating. Wet
snow may weigh about 12 pounds per cubic
foot. The weight of snow being pushed by your
plow may increase to several tons.
Allowing snow depth to grow to unmanageable
levels can cause difficult removal problems and
can be costly in terms of wear on equipment.
WARNING: Serious personal injury
can result from plowing at excessive
speeds, as well as costly damage to
equipment and property, if an obstruction is
encountered while plowing. Do not exceed
10 mph while plowing.
snow until a working area is cleared. Work small
areas in multiple passes to push snow to outer
edges. Generally, 6 inch snow can be plowed
with the entire blade width; 9 inch snow with
3/4 of the blade width; 12 inch snow with 1/2 of
the blade width. Local conditions will determine
how much work can be done before stalling or
getting stuck.
PARKING
Lower the plow to the ground when parking your
truck for a long period of time with the plow attached. Place the on/off switch in the “off” position to prevent the plow from drawing power
from the truck battery. The plow’s power unit
may continue to draw electrical current from the
truck battery if the control switch is left on; possibly resulting in insufficient charge to start the
truck.
REMOVING THE PLOW
To remove the snowplow from your truck, park
on a solid level surface with the blade straight
across the truck. Lower the plow to the ground
and leave the controller in the “float” mode.
NOTE: The plow control box must be in the
“float” mode to manually retract the lift cylinder
rod. If the cylinder rod cannot be retracted with
power on and the controller in float, loosen the
packing nut on the lift cylinder up to 1 1/2 turns
to reduce friction.
Plow snow in the lowest truck gear to transfer
maximum power to the cutting edge. Clear areas in front of buildings first. Back drag snow
away from buildings by driving to the building
with the plow raised, then dropping the blade to
pull snow away from buildings.
Clear large lots by angling the blade and creating a single path. Roll snow to outer edges
of the lot by taking successive passes with the
blade angled.
When plowing very deep snow, it may be necessary to raise the blade and shear off layers of
Lower Plow, Leave Controller in “Float” DWG NO. 4177
At the front of the truck, push down on the upper
lift links to fully retract the lift cylinder rod. Retracting the lift cylinder will orient the prong receivers correctly for reattaching the plow later.
Failure to retract the lift cylinder rod will allow
the lift frame to fall forward, possibly causing
personal injury or damage to plow components.
With the plow lowered to the ground and the controller in the “oat” mode, push down on the upper lift links to fully retract the lift cylinder rod.

place.
8 Operating Procedures
Disconnect the two electrical connectors by pulling them straight out from the receptacles. Do
not twist the connectors. Twisting will damage
the connector pins or the wiring harness.
Disconnect Plugs DWG NO. 3925
Back inside the truck, return control of the headlights to the truck and switch power off on the
snowplow control box, then slowly back the truck
out from the plow.
Turn Off Lights and Power DWG NO. 4178
NOTE: The stop plate will automatically fall forward as soon as the lift cylinder is fully extended for raising the blade prior to transporting the
plow.
If the snowplow won’t be used for an extended
period of time, the prong weldment can be removed from the truck by removing the hex bolts
that fasten it to the truck mount frame.
