SAFETY PRECAUTIONS
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.
PERSONAL SAFETY
• 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.
• Do not wear jewelry or a necktie, and secure long
hair.
• 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.
FIRE AND EXPLOSION
Be careful when using gasoline. Do not use gasoline
to clean parts. Store only in approved containers away
from sources of heat or flame.
CELL PHONES
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.
VENTILATION
SAFETY
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
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.
CAUTION
Refer to the Undercarriage Selection Guide
for minimum vehicle recommendations and
ballast requirements.
WARNING
Do not exceed GVWR or GAWR including the
blade and ballast. The rating label is found on
the driver-side vehicle door cornerpost.
WARNING
Remove blade assembly before placing
vehicle on hoist.
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.
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.
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.
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.

UNDERCARRIAGE INSTALLATION
INSTALLATION INSTRUCTIONS
NOTE: For easier assembly and installation, vehicle
and all snowplow components should be on a
smooth, level, hard surface, such as concrete.
1. Remove the air dam and bumper. Retain the

2. Remove compatibility structures, if equipped.
Retain them for reinstallation if the snowplow
mount is removed.
3. Remove the metal sway bar brackets and retain
for reinstallation later in this procedure.
4. Completely remove the sway bar fasteners and bolt
clips from the keyholes in the truck frame. Retain
the fasteners and clips for future reinstallation if the
mount kit is removed from the vehicle.
5. Place a spacer inside the passenger's side of the
truck frame with the slots closest to the center
of the vehicle. Insert a 7/16" x 2-1/2" cap screw
down through a 7/16" flat washer, the spacer,
the truck frame (and a washer on F-450 and
F-550 installations only).
6. Position the passenger-side rear bracket so the
cap screw goes through the appropriate hole.
Then place the sway bar in position and align the
sway bar bracket so the fastener is in the correct
hole. Attach a 7/16" locknut and hand tighten.
7. Insert a second 7/16" x 2-1/2" cap screw through
a washer, the spacer, truck frame, (a washer on
F-450 and F-550 installations only), rear bracket
and sway bar bracket. Attach a 7/16" locknut and
hand tighten.
8. Insert a 1/2" x 1-1/2" cap screw and 1/2" washer into
the truck frame and out through the front hole in the
rear bracket. Attach a 1/2" locknut and hand tighten.
9. Position the passenger-side mount so that the rear
hole is aligned with the rear hole in the bracket.
Insert a 1/2" x 1-1/2" cap screw through the hole in
the mount and rear bracket, attach a 1/2" locknut
and hand tighten.
10. Rotate the mount up against the truck frame.
Insert a 1/2" x 1-1/2" cap screw into the inner rear
hole at the front of the mount and through the
truck frame. Attach a 1/2" washer and locknut on
the inside of the truck frame and hand tighten.
11. Insert a 1/2" x 1-1/2" cap screw into the inner
front hole in the passenger-side mount. Attach a
1/2" locknut on the inside of the truck frame and
hand tighten.
12. Insert a 1/2" x 1-1/2" cap screw and 1/2" washer
into the truck frame and out through the outer
rear hole in the mount. Attach a 1/2" washer and
locknut and hand tighten.
13. Insert a 1/2" x 1-1/2" cap screw into the truck
frame and out through the outer front hole in the
mount. Attach a 1/2" locknut and hand tighten.
14. Install two more cap screws through the holes in
the mount and rear bracket. Attach locknuts to
fully secure the rear bracket to the mount. Hand
tighten fasteners.
Remove compatibility structures.
