SAFETY
SAFETY PRECAUTIONS
PERSONAL SAFETY
Improper installation and operation could cause
personal injury and/or equipment and property damage.
Read and understand labels and the Owner's Manual
before installing, operating or making adjustments.
• Remove ignition key and put the vehicle in park or
in gear to prevent others from starting the vehicle
during installation or service.
• Wear only snug-fitting clothing while working on
your vehicle or snowplow.
WARNING
• Do not wear jewelry or a necktie, and secure long
hair.
Lower blade when vehicle is parked.
Temperature changes could change
hydraulic pressure, causing the blade to
drop unexpectedly or damaging hydraulic
components. Failure to do this could result in
serious personal injury.
• Wear safety goggles to protect your eyes from
battery acid, gasoline, dirt and dust.
• Avoid touching hot surfaces such as the engine,
radiator, hoses and exhaust pipes.
• Always have a fire extinguisher rated BC handy,
for flammable liquids and electrical fires.
WARNING
The driver shall keep bystanders clear of the
blade when it is being raised, lowered or angled.
Do not stand between the vehicle and the blade
or within 8 feet of a moving blade. A moving or
falling blade could cause personal injury.
FIRE AND EXPLOSION
WARNING
Gasoline is highly flammable and gasoline
vapor is explosive. Never smoke while
working on vehicle. Keep all open flames
away from gasoline tank and lines. Wipe up
any spilled gasoline immediately.
WARNING
Keep hands and feet clear of the blade and
A-frame when mounting or removing the
snowplow. Moving or falling assemblies could
cause personal injury.
Be careful when using gasoline. Do not use gasoline
to clean parts. Store only in approved containers away
from sources of heat or flame.
WARNING
CELL PHONES
Do not exceed GVWR or GAWR including the
blade and ballast. The rating label is found on
the driver-side vehicle door cornerpost.
A driver's first responsibility is the safe operation of
the vehicle. The most important thing you can do
to prevent a crash is to avoid distractions and pay
attention to the road. Wait until it is safe to operate
Mobile Communication Equipment such as cell
phones or two-way radios.
WARNING
To prevent accidental movement of the
blade, always turn the ON/OFF switch to OFF
whenever the snowplow is not in use. The
control indicator light will turn off.
VENTILATION
WARNING
WARNING
Vehicle exhaust contains lethal fumes.
Breathing these fumes, even in low
concentrations, can cause death. Never
operate a vehicle in an enclosed area without
venting exhaust to the outside.
Remove blade assembly before placing
vehicle on hoist.
CAUTION
Refer to the Undercarriage Selection Guide
for minimum vehicle recommendations and
ballast requirements.

UNDERCARRIAGE INSTALLATION
4. Secure the front of each hanger plate to the
frame using cap screw with tab (Item 12), washer
(Item 9) and locknut (Item 10).
NOTE: For easier assembly and installation,
vehicle and all snowplow components should
be on a smooth, level, hard surface, such as
concrete.
1.
5. Mount the pushbeam (Item 1) square with the
bottom of each hanger plate using cap screws
(Item 8), washers (Item 9) and locknuts (Item 10).
If vehicle is equipped with fog lamps, disconnect
each electrical harness. Remove the bumper
fascia.
NOTE: Due to different truck frame widths,
spacers are provided to prevent the hanger plates
from being bent when installing the pushbeam.
Use these spacers (Item 7) if the pushbeam does
not mount flush to the hanger plates.
NOTE: The bumper fascia may need to be
permanently notched to accommodate the
undercarriage assembly.
2. Align each hanger plate (Item 6) with the holes on
the outside of the truck frame rail.
Tighten pushbeam hardware according to torque
specifications.
NOTE: Use the holes specified for the correct
vehicle year. The hardware kit includes all
hardware needed for the different vehicle years
identified.
6. Level the pushbeam with the floor and torque
the hanger plate hardware. Verify T-bolts are
positioned with "T" perpendicular to the slot in the
truck frame.
3. Using flexible wire, position cap screw with handle
(Item 11) through the rear access hole in the truck
frame rail and out the rear hanger plate mount
hole on the frame. Secure hanger plate with
washer (Item 9) and nut (Item 10). Finger tighten
the fasteners until all undercarriage parts are in
place.
7.
Replace the bumper fascia and reconnect the fog
lamp wiring, if applicable.
NOTE: After five to ten hours of snowplow usage,
retorque all undercarriage assembly fasteners.
NOTE: The '04 Ford Ranger requires T-bolt
(Item 13) in this location. Position the T-bolt into
the oval hole (may need to grind slightly) in the
frame. Mark the end of each T-bolt to indicate
which direction the "T" will face when it is
installed inside of the frame rail. Secure with lock
washer (Item 15) and nut (Item 14).
