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.
3. Do not service or otherwise handle a plow
in the raised position unless it is securely
blocked against unexpected falling. Likewise, when servicing a plow with the wings
extended, block wings to prevent unexpected wing movement due to accidental loss of
hydraulic pressure or cylinder removal.
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.
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.
Do not use your hand to check for leaks.
Use a piece of paper or cardboard to nd
suspected leaks.
Tighten all connections before pressurizing
hydraulic lines.
If uid is injected into the skin, get medical
attention immediately to prevent serious infection.
3. Check all controls and operating functions
of the machine in a safe area before starting to work.
DURING OPERATION
1. Always wear seat belts when operating a
motor vehicle.
2. Ensure everyone is clear of the machine,
especially away from blind areas of the operator, before starting, actuating hydraulics
or operating this equipment.
3. Do not plow snow at excessively high
speeds.
4. Avoid hitting objects that will damage your
plow or truck.
5. Set the brakes and stop the truck’s engine
before adjusting or servicing your plow.
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.
AFTER OPERATION
1. Park the plow on a solid, level surface. Fully
collapse the lift cylinder and use the stop
plate, as described on page 7, before unhitching the plow to prevent the frame from
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.
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.
Handle Pinned With Plow On Truck DWG. NO. 6003
Plug in the three 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 parking stand
index plate to raise the stand to its highest position. Reinstall the pin in the plate 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. 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.
DWG. NO. 5995
Alignment Tab and Slot DWG. NO. 5232
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.
To make alignment of the plow easier in the future, mark a point on the back of the LH 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.
Operating Procedures 5
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. Two push
buttons on the box are used to extend both wings
to the scoop position or retract both wings to the
V-position.
NOTE: Drawings 4181 and 4163 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 24 for switching
the controller joystick and face plate.
The vehicle’s electrical power must be turned on
before the control box will function.
Raise and lower the plow by moving the joystick
forward and backward. Hold the plow at an intermediate height by releasing the joystick from the
“Raise” position when the plow reaches the desired height. Moving the joystick to the “Lower” position will lower the blade to the ground and allow
the plow to “Float” along the contour of the ground
while plowing snow. The green light on the control
box will turn yellow to indicate the plow is in the
oat mode. Momentarily moving the joystick to the
“Raise” position will remove the plow from the oat
mode and the yellow light will return to green.
Raise the blade before working the wing functions
of the plow to avoid resistance from the ground.
Move the joystick left or right to angle the blade to
that side. Push the left button on the control box to
extend both wings into the scoop position. Push
the right button to retract both wings into the Vposition.
To hold the wings in position straight across the
truck, start with the plow in the V-position, then
push the left button on the control box to move
both wings forward together and release the button when the wings are at the desired position.
VEE
Joystick Control Box DWG. NO. 4181
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. Activate high beam/
low beam and turn signal/parking lamps from the
truck as you normally would without the plow attached.
NOTE: When removing the plow, remember to
place the headlight switch in the “Truck” position
to return power to the truck’s headlights.
TRANSPORTING THE PLOW
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.
Fully raise the plow, then move the wings into the
V-position 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 wings while
transporting the plow.
6 Operating Procedures
PLOWING SNOW
WARNING: Always wear a seat belt when
plowing snow. Sudden contact with a hidden object can result in serious 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.
Level the plow in the scoop position by loosening
the hardware through the front of the pushframe and
through the diagonal braces to allow the plow to settle to the ground. Retighten the hardware once the
plow is level.
Plow snow in the lowest truck gear to transfer maximum power to the cutting edge. Clear areas in front
of buildings rst. Backdrag snow away from buildings
by driving to the building with the plow raised, then
dropping the blade to pull snow away. Push snow to
outer edges of the lot after snow is away from buildings.
Begin clearing large lots by putting the plow in the Vposition and creating a single path. Roll snow to the
outer edges of the lot by taking successive passes
with the blade angled, or put the plow in the scoop
position and push snow to the end of the lot. Break
up hard snowbanks with the plow in the V-position.
When plowing very deep snow, it may be necessary
to raise the blade and shear off layers of 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.
DWG. NO. 5996
Adjust the skids at the back of the moldboard 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 lev-
els can cause difcult removal problems and can be
costly in terms of wear on equipment.
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 insufcient 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 “oat’ mode.
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.
Lower Plow, Leave Controller In “Float” DWG. NO. 4163
NOTE: The plow control box must be in the “oat”
mode to manually retract the lift cylinder rod. If the
cylinder rod cannot be retracted with power on and
the controller in oat, loosen the packing nut on
the lift cylinder up to 1 1/2 turns to reduce friction.
Retracting the lift cylinder before removing the
plow from the truck 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.
Operating Procedures 7
With the plow lowered to the ground and the con-
troller in the “oat” mode, push down on the upper
lift links to full retract the lift cylinder rod.

Disconnect Plugs DWG. NO. 5233
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. 4164
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.

MAINTENANCE
Maintenance 11
WARNING: Do not service or otherwise handle a plow in the raised po-
sition unless it is securely blocked
against unexpected falling. Likewise, when
servicing the plow with the wings extended,
block wings to prevent unexpected wing
movement due to accidental loss of hydraulic pressure or cylinder removal.
Dependable snowplow operation is the result of
following good maintenance procedures. Inspect
your plow frequently to ensure that all parts are
working smoothly, and develop a schedule for
maintenance at required intervals.
GENERAL
Wash salt and dirt off the plow before storage.
Touch-up any chips or scratches in the paint
and apply a light coating of grease to extended
cylinder rods to prevent corrosion.
Carefully unbolt the oil reservoir from the power
unit and discard old oil.
Clean the suction filter at the pump inlet and
wipe any metal shavings off the magnet on the
pump.
Re-attach the reservoir onto the power unit and
re-connect the power unit on the snowplow before adding new hydraulic oil.
Pour hydraulic oil into the power unit reservoir
until the oil level reaches the fill level.
HYDRAULIC SYSTEM
The majority of snowplow operational problems
are caused by bad oil in the hydraulic system.
Hydraulic oil should be changed every year for
best performance. Select Hiniker Cold Flow Hydraulic Oil or an equivalent oil that meets military specification 5606, for plowing in extremely
cold temperatures.
Change hydraulic oil with the wings in the
V-position and the plow on the ground. Disconnect three electrical wiring harnesses from the
power unit and uncouple five hydraulic lines.
Unbolt the power unit from the plow, and remove it to a clean working area that can capture
any spilled oil.
DWG. NO. 6453A
Raise and lower the plow, and cycle the wings
to purge any air trapped in the system. Check
the oil level with the plow on the ground and the
wings retracted. Add oil to the fill level, if necessary, but do not overfill the reservoir.
12 Maintenance
MECHANICAL COMPONENTS
Prior to the operation of a new snowplow, or one
which has been stored, inspect all hardware and
verify proper torque on all bolts and nuts in accordance with the recommended torque specifications.

ELECTRICAL MAINTENANCE
Periodically check all electrical connections for
proper fit and remove any contamination that
may be present.
To prevent contamination always place dust
caps on connectors when not in use. This is
particularly important when the plow is being
stored. The use of dielectric grease is recommended to reduce corrosion of the contacts and
to make connecting and disconnecting easier.
Before each season check the vehicle battery
and electrical system for proper operation. A
weak battery, dirty terminals, or faulty charging
system may cause improper operation and possible failure of the joystick controller.
Before every plowing season, and throughout
the season, check the snowplow headlamps for
proper function and aim. Refer to sections titled
“System Check-Out” and “Headlamp Aiming
Procedure” in this manual for instructions.
Loose bolts can cause hole elongation and part
failure resulting in dangerous operating conditions and equipment breakdown.
Check all hardware periodically during the plowing season and keep tightened to specified
torques. Replace worn bolts and lock nuts with
grade 5 bolts and equivalent type B or type F
lock nuts. Type B lock nuts are plain hex; type F
lock nuts are flanged hex.
Inspect wear of the cutting edges before every
plowing season and frequently throughout the
season. Replace cutting edges before wear is
into wing or mast sections to avoid damage to
these components.
The 5/16” hex bolts in the latch sliders are factory retained with anaerobic threadlock. If removal or replacement of these bolts is necessary, purchase new bolts with threadlocker from
your Hiniker dealer, or apply a commercially
available threadlock, i.e., Loctite 242 (blue) to
standard 5/16-18 x 3/4” grade 5 hex bolts before reassembly.
