TRANSPORTING SNOWPLOW
These instructions are for driving short distances to
and from plowing jobs. For long trips, remove the
snowplow from the vehicle, following recommended
mechanical lifting cautions and procedures.
1. Completely raise the blade.
2. Adjust the blade height for maximum vehicle
headlamp illumination.
3. Adjust the blade to the straight position.
OPERATING YOUR SNOWPLOW
WARNING
Position the blade so it does not block the
vehicle headlamp beam.
Do not change blade position while traveling.
You could suddenly lower blade accidentally.
DRIVING AND PLOWING ON SNOW
AND ICE
Refer to vehicle owner's manual instructions for
driving in snow and ice conditions. Remember, when
you drive on snow or ice, your wheels will not get good
traction. You cannot accelerate as quickly, turning
is more difficult, and you will need longer braking
distance.
Wet and hard-packed snow or ice offers the worst
traction. It is very easy to lose control. You will have
difficulty accelerating. If you do get moving, you may
have poor steering and difficult braking, which can
cause you to slide out of control.
Here are some tips for driving in these conditions:
• Drive defensively.
• Do not drink, then drive or plow snow.
• Plow or drive only when you have good visibility
for operating a vehicle.
• If you cannot see well due to snow or icy
conditions, you will need to slow down and keep
more space between you and other vehicles.
• Slow down, especially on higher-speed roads.
Your headlamps can light up only so much road
ahead.
• If you are tired, pull offin a safe place and rest.
• Keep your windshield and all glass on your vehicle
clean to see around you.
• Dress properly for the weather. Wear layers of
clothing; as you get warm, you can take offlayers.
CAUTION
Transport speed should not exceed vehicle
manufacturer's recommendations. Further
reduce speed under adverse travel conditions.
WARNING
Drinking then driving or plowing is very
dangerous. Your reflexes, perceptions,
attentiveness, and judgment can be affected
by even a small amount of alcohol. You can
have a serious or even fatal collision if you
drive after drinking. Please do not drink and
then drive or plow.

Lit. No. 57992, Rev. 02 17 April 15, 2021
OPERATING YOUR SNOWPLOW
PLOWING SNOW
NOTE: Only the driver should be in the vehicle cab
when the snowplow is attached.
General Instructions
1. Before plowing, make sure that you know of any
obstructions hidden beneath the snow, such as
bumper stops in parking lots, curbs, sidewalk
edges, shrubs, fences, or pipes sticking up from
the ground. If unfamiliar with the area to be
plowed, have someone familiar with the area point
out obstacles.
2. If possible and you have good visibility, plow
during the storm rather than letting snow
accumulate.
3. Do not exceed 10 mph (16 km/h) when plowing
snow.
CAUTION
Wear a seat belt when plowing snow. Hidden
obstructions could cause the vehicle to stop
suddenly, resulting in personal injury.
CAUTION
Never stack snow with the blade angled. This
could damage the snowplow.
CAUTION
Flag any obstructions that are hard to locate
under snow to prevent damage to product or
property.
CAUTION
Plowing speed should not exceed 10 mph
(16 km/h).
Hard-Packed Snow
1. Raise the disc shoes so that the cutting edge
comes into direct contact with the pavement.
2. Use the lowest gear to place maximum power
behind the cutting edge.
3. An angled blade is more effective for removing
hard-packed snow.
Deep Snow
1. For straight blades, shear offtop layers by plowing
with the blade raised 3 to 4 inches for the initial
pass.
2. Bite into the edges using only partial blade width
until the job is cut down to size for full-blade
plowing.
Rule of thumb:
6" of snow — plow with entire blade width;
9" of snow — plow with 3/4 blade width;
12" of snow — plow with 1/2 of the blade.
Experience and "feel" are the best guides.
3. When plowing deep snow, be sure to keep the
vehicle moving.
4. For increased traction, use tire chains where legal.

Lit. No. 57992, Rev. 02 18 April 15, 2021
OPERATING YOUR SNOWPLOW
Clearing Driveways
1. Head into the driveway with the blade angled and
plow the snow away from any buildings. Widen
driveway by rolling snow away from any buildings.
2. If a building is at the end of the driveway, plow to
within a vehicle length of the building. Push as
much snow as possible offthe driveway.
3. With a raised blade, drive through remaining
snow to building. Drop blade and back drag snow
away from the building at least one vehicle length.
Repeat if necessary.
4. Back vehicle to the building and plow forward,
removing the remaining snow from the driveway.
Check municipal ordinances for proper disposal of
snow.
Clearing Parking Lots
1. Clear areas in front of buildings first. With blade
raised, drive up to the building. Drop blade and
back drag the snow away from building. When
snow is clear of the buildings, turn the vehicle
around and push snow away from the buildings
toward outer edges of lot.
2. Plow a single path down the center in the
lengthwise direction.
3. With the blade in the angle position, plow
successive strips lengthwise until the area is
cleared and snow is stacked around the outer
edges.
4. If snow is too deep to clear in above manner, clear
main traffic lanes as much as possible. Check
municipal ordinances for proper disposal of snow.
PARKING WITH SNOWPLOW ATTACHED
Whenever you park your vehicle, completely lower the
blade to the ground.
TOWINGADISABLEDORSTUCKVEHICLE
Do not use any snowplow components as an attaching
point when retrieving, towing or winching a disabled or
stuck vehicle.
WARNING
Lower the blade when the vehicle is parked.
Keep 8 feet clear of the blade when it is being
raised, lowered, or angled. 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.

Lit. No. 57992, Rev. 02 19 April 15, 2021
PRESEASON CHECK
Before the snow season, check your equipment to
make sure that it is in working condition. Here are
some tips for getting your equipment ready:
• Replace worn or damaged parts.
• Check all mounting points and tighten fasteners,
on both snowplow and vehicle. Verify that all
cotter pins are in place.
• Repaint blade assembly and attachments, as
necessary, to protect the metal.
• Install auxiliary and flashing lights for compliance
and visibility in accordance with local regulations.
• Check vehicle headlamps, auxiliary lights, heater,
and windshield wipers for proper operation.
• Inspect and test your battery. Recharge or replace
as necessary.
• Ballast may be necessary, or beneficial, on some
vehicles to provide maximum traction, braking,
and handling.
• Any ballast material (such as sand and blocks)
must be solidly secured to the vehicle, preventing
it from moving under harsh plowing conditions.
MAINTENANCE
WARNING
Lower the blade when the vehicle is parked.
Keep 8 feet clear of the blade when it is
being raised, lowered or angled. 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.
POSTSEASON MAINTENANCE
NOTE: Coat all electrical connections with
dielectric grease.
• Clean and paint blade and components as
needed.
• Apply general purpose petroleum grease to
exposed chrome surfaces of the rams to prevent
rust.
• Lubricate all pivot points with general purpose
petroleum grease.

Lit. No. 57992, Rev. 02 20 April 15, 2021
MAINTENANCE
MAINTENANCE AND ADJUSTMENT
Your BLIZZARD®snowplow is designed for rugged,
dependable service. However, like the vehicle
on which it is mounted, it needs regular care and
maintenance.
Check the following before and frequently during the
plowing season:
1. Make sure that all fasteners, mounting bolts, and
hydraulic connections are tight. Pay particular
attention to the 1" pivot bolt.
2. Check all plugs and seals for hydraulic fluid leaks.
Repair as necessary.
CAUTION
Overtightening springs will not increase blade
trip force and can damage the springs.
WARNING
Lower the blade when the vehicle is parked.
Keep 8 feet clear of the blade when it is being
raised, lowered, or angled. 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.
3. Trip Spring Adjustment: To adjust trip spring
tension, adjust the eyebolts located at the top
of the blade. Tighten the adjusting nut until the
coils begin to separate. When tension is properly
adjusted, a sheet of paper should pass between
the second and third coils. When the proper
tension is reached, tighten locknut.
4. Blade Finish: If the powder-coated finish is
nicked or scratched, repair the surface and paint
with BLIZZARD white or black paint (available in
aerosol or quart cans).
