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 equip
ment design and distribution. However, many
accidents occur because a few seconds of
thought, and a more careful approach to han
dling, 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. Like
wise, when servicing a plow with the wings
extended, block wings to prevent unexpect
ed 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 find
suspected leaks.
Tighten all connections before pressurizing
hydraulic lines.
If fluid is injected into the skin, get medical
attention immediately to prevent serious in
fection.
3. Check all controls and operating functions
of the machine in a safe area before start
ing 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 op
erator, 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 with the upper lift
links before unhitching the plow to prevent
the plow 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 before remov
ing 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 receiv
ers 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. 4166
Plug in the three electrical connectors be-
-
tween 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. 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. 5293
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 fu
ture, 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.
THE JOYSTICK CONTROLLER
The joystick control box has slide switches for con
trolling 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 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 and lower the plow by moving the joystick
forward and backward. Hold the plow at an inter
-
mediate 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
float mode. Momentarily moving the joystick to the
“Raise” position will remove the plow from the float
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.
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 at
tached.
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 but
-
ton when the wings are at the desired position.
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 airflow 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 hid
den object can result in serious personal
injury.
Inspect areas to be plowed before snowfall for poten
tial 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 en
closed areas and locate sites for stacking snow.
Level the plow in the scoop position by first loosening
the jam nut on the stop bolt at the back of the center
mast with a 1-1/2 inch open-end wrench, then turning
the bolt in or out to adjust the plow ends. Retighten
the jam nut once the plow is level with the ground.
Plow snow in the lowest truck gear to transfer maxi
mum power to the cutting edge. Clear areas in front
of buildings first. 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 build
ings.
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 de
termine how much work can be done before stalling
or getting stuck.
DWG NO. 3847
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 in
crease to several tons.
Allowing snow depth to grow to unmanageable lev
els can cause difficult 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 electri
cal 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.
-
-
WARNING: Serious personal injury can re
sult 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 “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.
At the front of the truck, push down on the upper
lift links to fully retract the lift cylinder rod. Retract
ing 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.

10 Maintenance
MAINTENANCE
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.
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.
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 be
fore adding new hydraulic oil.
Pour hydraulic oil into the power unit reservoir
until the oil level reaches the fill level.
-
HYDRAULIC SYSTEM
DWG NO. 3066
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 a high quality oil that
is appropriate for the temperatures in which you
will be plowing snow.
DWG NO. 5847
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.
Maintenance 11
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 ac
cordance with the recommended torque specifications.

*Applications without lock nuts.
Loose bolts can cause hole elongation and part
failure resulting in dangerous operating condi
tions and equipment breakdown.
Check all hardware periodically during the plow
ing 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 and the cen
ter cone before every plowing season and frequently throughout the season. Replace cutting
edges and the center cone before wear is into
wing or mast sections to avoid damage to these
components.
The three 5/8 inch flat socket head screws that
fasten the center cone to the bottom of the plow
are factory retained with anaerobic threadlock
er. If removal or replacement of these screws is
necessary, purchase new screws with threadlocker from your Hiniker dealer or apply a commercially available threadlock, i.e., Loctite 242
(blue) to the threads before reassembly. Torque
all three screws to 125 Ft. lbs (170 N-m).
Once a year before using the plow, check that
the plow will trip freely about its trip pin. With
the plow mounted on the truck and lowered to
the ground, loosen the four trip springs and pull
-
the top of the moldboard forward. If the mold
board doesn’t pivot freely, remove the trip pin
and apply a commercially available anti-seize
lubricant. Damage to the plow or truck may result if the moldboard hits an obstruction during
use and doesn’t trip.
Retighten the trip springs by turning the nuts on
the spring studs until the coils begin to sepa
rate. Secure spring studs by tightening top and
bottom nuts together to produce a rigid clamp.
At least once a year, grease the center hinge
pin on the moldboard by injecting a high quality,
general purpose grease into each bushing pin
hole with a grease syringe.
Grease the adjustable stop bolt behind the cen
ter mast at least once a year with a high quality,
general purpose grease to prevent corrosion.
The 5/16” hex bolts in the latch sliders are fac
tory retained with anaerobic threadlock. If re-
-
moval 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.
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 recom
mended to reduce corrosion of the contacts and
to make connecting and disconnecting easier.
Before each season check vehicle battery and
electrical system for proper operation. A weak
battery, dirty terminals, or faulty charging sys
tem may cause improper operation and possible
failure of the joystick controller.
