Hiniker 7812 Operator's Manual page 7

Check that the plow headlamps and turn signals
are operational, and headlamps are aimed cor-
rectly. 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 head lamp, 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.
NOTE: Drawings 4176 and 4177 show the raise
and lower functions of the joystick controller as
received from the factory. Functions may be re-
versed 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.
Joystick Control Box
Place the on/off switch on the joystick control box
in the "On" position to supply power to the snow-
plow. 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.
Raise or lower the plow by moving the joystick to
the "Raise" or "Lower" position.
Hold the plow at an intermediate height by releas-
ing 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
"Float" along the contour of the ground while plow-
ing snow.
A yellow light on the control box indicates the plow
is in the float mode. Momentarily moving the joy-
stick to the "Raise" position will remove the plow
from the float 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 de-
sired angle.
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 ve-
hicle's cooling system, possibly causing the ve-
hicle 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 inter-
fere with the headlights before driving.
DWG NO. 4176
Transport the plow with power to the joystick con-
trol box switched off to prevent accidental lowering
of the plow.
Never adjust the blade height or angle the blade
while driving.
