SAFETY
SAFETY PRECAUTIONS
CAUTION
Refer to the Undercarriage Selection Guide
for minimum vehicle recommendations and
ballast requirements.
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.
HYDRAULIC SAFETY
WARNING
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.
Hydraulic fluid under pressure can cause skin
injection injury. If you are injured by hydraulic
fluid, get medical attention immediately.
• Always inspect hydraulic components and hoses
before using. Replace any damaged or worn parts
immediately.
WARNING
• If you suspect a hose leak, DO NOT use your
hand to locate it. Use a piece of cardboard or
wood.
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.
FUSES
The BLIZZARD® electrical and hydraulic systems
contain several blade-style automotive fuses. If
a problem should occur and fuse replacement is
necessary, the replacement fuse must be of the same
type and amperage rating as the original. Installing a
fuse with a higher rating can damage the system and
could start a fire. Fuse Replacement, including fuse
ratings and locations, is located in the Maintenance
Section of the Owner's Manual.
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
Do not exceed GVWR or GAWR including the
blade and ballast. The rating label is found on
the driver-side vehicle door cornerpost.
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.
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.
• Wear only snug-fitting clothing while working on
your vehicle or snowplow.
• Do not wear jewelry or a necktie, and secure long
hair.
WARNING
• Wear safety goggles to protect your eyes from
battery acid, gasoline, dirt and dust.
Remove blade assembly before placing
vehicle on hoist.
• Avoid touching hot surfaces such as the engine,
radiator, hoses and exhaust pipes.
CAUTION
• Always have a fire extinguisher rated BC handy,
for flammable liquids and electrical fires.
Overtightening springs will not increase blade
trip force and can damage the springs.

FIRE AND EXPLOSION
TORQUE CHART
WARNING
CAUTION
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.
Read instructions before assembling.
Fasteners should be finger tight until
instructed to tighten according to the torque
chart. Use standard methods and practices
when attaching snowplow including proper
personal protective safety equipment.
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

BATTERY SAFETY
CAUTION
Batteries normally produce explosive gases
which can cause personal injury. Therefore,
do not allow flames, sparks or lit tobacco
to come near the battery. When charging or
working near a battery, always cover your
face and protect your eyes, and also provide
ventilation.
Batteries contain sulfuric acid which burns
skin, eyes and clothing.

the blade will be assembled. Remove the blade
from the pallet and place it face down. Position
the A-frame assembly onto the blade, aligning the
pivot beam holes with the pivot holes in the blade.
Insert two 3/4" x 6" clevis pins from the outside.
Secure the pivot beam by installing 1/4" x 2" cotter
pins in the two clevis pins.

Brackets
Locknut
3. Push the threaded ends of the eyebolts through
the holes in the spring bar on the blade. Attach a
5/8" locknut to each eyebolt.
CAUTION
Clevis Pin
Overtightening springs will not increase blade
trip force and can damage the springs.

Before assembling the mount adapter to the
vehicle undercarriage, determine if the height
adjustment plates are needed.
2. Prior to measuring the vehicle undercarriage
height, the undercarriage must be installed, and
ballast must be installed if required. Park the
vehicle on a level surface. Measure the distance
from the ground to the center of the adapter
mounting hole on the undercarriage.

BLADE DROP SPEED ADJUSTMENT
VEHICLE LIGHTING CHECK
WARNING
1.
Keep 8' clear of the blade drop zone when it is
being raised, lowered or angled. Do not stand
between the vehicle and blade or directly in
front of blade. If the blade hits you or drops
on you, you could be seriously injured.
1.
Verify the operation of all vehicle front lighting
prior to connecting the snowplow harness.
2. Check the operation of the snowplow lights with
snowplow mounted to vehicle and all harnesses
connected.
Turn signals and parking lamps
The plow drop speed may be adjusted by turning
the needle valve.
Parking lamps ON:
• Both vehicle and snowplow parking lamps
should be ON at the same time.
NOTE: The blade will not drop when drop speed
needle valve is fully tightened (clockwise). Turn
OFF the plow control, turn the needle valve
1/8 turn outward (counterclockwise), then proceed
with blade drop speed adjustment.
Driver-side turn signal ON:
• Both vehicle and snowplow driver-side turn
signal lamps should flash at the same time.
Passenger-side turn signal ON:
• Both vehicle and snowplow passenger-side
turn signal lamps should flash at the same time.
2. Lower the blade to the ground before making
adjustment.
3. Turn the needle valve inward (clockwise) to
decrease the drop speed. Turn the needle valve
outward (counterclockwise) to increase the drop
speed.
Headlamps
Move vehicle headlamp switch to the
"ON" position. Connecting and disconnecting the
snowplow lighting harness plug should switch the
lights between vehicle and snowplow as follows:
4. Stand 8' clear of the blade drop zone when
checking adjustment.

Snowplow lighting harness DISCONNECTED:
• Vehicle headlamps should be ON.
• Snowplow headlamps should be OFF.
Snowplow lighting harness CONNECTED:
• Snowplow headlamps should be ON.
• Vehicle headlamps should be OFF.
Dimmer switch should toggle headlamps between
high and low beams. The high beam indicator on
the dash should light when headlamps are placed
in high beam.

OPERATIONAL TEST AND FINAL ADJUSTMENTS
Daytime Running Lamps (DRLs)
Hand-Held Control
An operational check of the vehicle and snowplow
DRLs will depend on the vehicle model, vehicle
DRL system and type of Isolation Module
installed. Due to the variations in the OEM DRL
systems and the different Isolation Module
options available, checking the functionality of the
snowplow DRLs will depend on the type of module
installed on the vehicle.
The snowplow plugs do need to be connected to
the vehicle harness connectors. The control power
indicator light should light whenever the control
ON/OFF switch and the ignition (key) switches are
both in the "ON" position.
3. Connect all snowplow and vehicle harnesses.
Raise the snowplow and aim snowplow
headlamps according to the Snowplow Headlamp
Beam Aiming instructions included with the
headlamps and any state or local regulations.
With headlamp switch OFF, activate the vehicle
DRLs.
Snowplow lighting harness DISCONNECTED:
• Vehicle DRLs should be ON.
• Snowplow headlamps should be OFF.
4. Check aim of vehicle headlamps with snowplow
removed.
CAUTION
Snowplow lighting harness CONNECTED and
vehicle in DRL mode:
• Check snowplow DRL function per the type of
Isolation Module installed.
On 2-Plug electrical systems, plug covers
shall be used whenever snowplow is
disconnected. Vehicle Battery Cable is 12-volt
unfused source.
Refer to the Mechanic's Guide for information on
the Isolation Module DRL functions.
Lit. No. 40693, Rev. 02
5. When the snowplow is removed from the vehicle,
install plug covers on the vehicle battery cable
and lighting harness. Insert the snowplow battery
cable and lighting harness into the cable boot on
the snowplow.
