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, text messaging devices, pagers 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 control OFF whenever the
snowplow is not in use. The power 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. Check to ensure that the vehicle's front bumper
is level and in a desirable position. Adjust if
necessary. Remove three of the bumper bracket
fasteners on each side of the truck. Do not
loosen the fourth bumper bracket cap screw as it
maintains the preset bumper position during this
step.
2. For both sides, cut the cable ties to free the
harness and remove the L-brackets as shown
below. Retain all bracket parts for reinstallation.
Use caution not to damage the brake cable and
hose running from the L-shaped bracket to the
wheel assembly.
3. On the driver's side, remove the two fasteners
shown above. Remove the plastic fender shown.
4. On the passenger's side, remove the jounce stop
fasteners and the jounce stop.

using 1/2" x 2" and 1/2" x 2-1/2" cap screws and
locknuts. Use caution not to damage the lighting
harness running under the passenger-side frame
end. It may be necessary to cut its plastic tie and
reposition the lighting harness temporarily during
this step. If so, use one of the provided cable ties
to reattach it.
6. On the driver's side, loosely attach the front mount
using 3/4" x 2-3/4" cap screws and locknuts and
one 5/8" x 3" cap screw and locknut.
7. On both sides, loosely attach the corresponding
thrust arm to the inside of the front mount using
three 5/8" x 2" cap screws and locknuts.
8. Position the rear end of the passenger-side thrust
arm as shown and attach using 1/2" x 2" cap
screws and locknuts.
9. On the passenger's side, mark a 3/4" hole using
the passenger-side thrust arm as a template.
Remove the thrust arm and drill hole. Reattach
the thrust arm using 3/4" x 2-3/4" and 1/2" x 2"
cap screws and locknuts.
The 5/8" hole is not used on this side.

MOUNT ADAPTER MEASUREMENT
With the vehicle on level ground, measure from the
ground to the center of the hole on the U-bracket side
plate on the mount.
The height of the mount should be 16" or less from
the center of the U-bracket hole to level ground. The
appropriate adapter plates need to be attached to the
mount adapter. (The mount adapter comes packaged
with the blade crate assembly.)
If the measured height is 16" or less, install the short
height adjustment adapter plates as described.
MOUNT ADAPTER INSTALLATION
Install adapter plates as follows:
1. Position the adapter plate against the driver's side
portion of the mount adapter as shown. Insert a
3/4" x 2-3/4" cap screw through the lower front
adapter plate hole and through the appropriate
hole on the mount adapter. Secure with a locknut.
2. Insert a cap screw through the rear adapter plate
hole, through the slot on the mount adapter and
through a washer. Secure with a locknut.
3. Repeat for the passenger's side. Tighten all
fasteners according to the torque chart.
