WARNING
When using on a vehicle with air bags, DO NOT tamper
with, disable or remove any components related to
the operation of the air bags. Vehicles equipped with
air bags are designed such that the air bags will be
activated in a frontal collision equivalent to hitting a
solid barrier (such as a wall) at approximately 14 mph
or more, or, roughly speaking, a frontal perpendicular
collision with a parked car or truck of similar size at
approximately 28 mph or more. Careless or high speed
driving while plowing snow, which results in vehicle
decelerations equivalent to or greater than the air bag
deployment threshold described above, could deploy
the air bag.

IMPORTANT APPLICATION NOTICE
The Snow Plow Selector at www.SnowDogg.com is for reference only. All calculations are based upon the best available
information including vehicle curb weights, and truck geometry. It is the operator's responsibility to ensure that the Front
Gross Axle Weight Rating (FGAWR), Rear Gross Axle Weight Rating (RGAWR), and Gross Vehicle Weight Rating (GVWR) are not
exceeded with the plow and ballast mounted.
Vehicle application recommendations are based on the following:
• The vehicle with the snowplow installed must comply with applicable Federal Motor Vehicle Safety Standards (FMVSS).
• The vehicle with the snowplow installed must comply with the vehicle manufacturer's stated gross vehicle and axle weight
ratings (found on the driver-side door corner post of the vehicle) and the front and rear weight distribution ratio. In some
cases, rear ballast may be required to comply with these requirements.
• In some cases, there may be additional limitations and requirements.
• Available capacity decreases as the vehicle is loaded with cargo or other truck equipment, or snowplow accessories are
installed.
• If there is uncertainty as to whether available capacity exists, the actual vehicle as configured must be weighed.

MAINTENANCE
Your SnowDogg®plow as installed by your dealer is ready
for use but needs regular maintenance and inspection.
Preparing Your Plow for the Season
Prior to connecting your plow to your truck:
1. Inspect your plow for any damage and make any repairs.
Make sure to examine:
• Welds
• Hydraulic hoses
• Electrical connectors/harnesses
• Rusting areas/damaged paint
2. Ensure hydraulic fittings are properly tightened. Fittings
will loosen due to vibrations from normal use.
3. Coat all electrical connection points with dielectric grease.
4. Connect your plow to your truck to continue the inspection:
• Check for proper operation in terms of movement and
plow lights.
• Check the aim of your plow lights adjust if necessary.
See page 16 for instructions.
• Grease all grease fittings on trip pins and king pin/hinge.
• Drain the hydraulic system and replace with
SnowDogg®Low Temp Hydraulic Fluid (#16150010) See
page 17 for instructions.
• Check your cutting edges and shoes for wear and
replace as necessary.
Preparing Your Truck for the Season
Pushing a plow can be very hard on your truck. Keep up
with regular truck maintenance to ensure your truck is ready
for the season ahead.
1. Prior to the season, it’s critical that you have the
following checked and repaired as necessary:
• Charging system
• Cooling system
• Lighting system
• Transmission
• Brakes
• Wheel alignment
2. Check the following installation components:
• Ensure all electrical connections are properly tightened.
A loose or dirty connection can draw twice as much
current as a clean one, which will result in excessive heat
and eventual component failure.
• Inspect all harnesses for damage, and repair or replace
as necessary.
• Inspect the truck frame/plow mount attachment/push
bar, and repair or replace as necessary.
3. Curb Weight and Operator Responsibility
• If there is any question about curb weight and/or
weight distribution it is always best to ensure that the

12
Front Gross Axle Weight Rating (FGAWR), Rear Gross
Axle Weight Rating (RGAWR), and Gross Vehicle Weight
Rating (GVWR) are not exceeded with the plow and ballast
mounted.
• The ballast and application recommendations at
www.SnowDogg.com are for reference only. All
calculations are based upon the best available information
including vehicle curb weights, and truck geometry. It
is the operator’s responsibility to ensure safe operation
of the vehicle and proper loading. The operator must
properly secure ballast when used.
IN-SEASON MAINTENANCE
You rely on your SnowDogg®plow to be at peak
performance in the most critical conditions. If you
don’t want minor issues to turn into major repairs or
replacements, then inspect and repair your plow regularly.
After every plowing event, follow this easy maintenance
check list:
• Check all weldments for cracks or incidental damage.
• Check all linkages and moving parts for free and
smooth operation.
• Inspect hydraulic hoses for cracks and damage.
• Check hoses for leaks.
• Hand check and tighten all fittings.
• Inspect all connections for pin damage or evidence of
corrosion.
• Ensure that fasteners, and plow and truck mount are
properly torqued.
• Check your cutting edges and shoes for wear and
replace as necessary.
• Ensure all electrical connections are properly
tightened. A loose or dirty connection can draw twice
as much current as a clean one, which will result in
excessive heat and eventual component failure.
• Test plow light operation.
Preparing Your Plow for Storage
Prior to disconnecting your plow from your truck:
• Extend and grease all chrome cylinder rods.
• Fully compress all cylinders where possible.
After disconnecting your plow from your truck:
• Coat all electrical connection points with dielectric grease.
• Repair/touch up any chipped paint or rusted areas.
• Apply a coat of oil or grease to all exposed chrome on
angle and lift cylinders.
• Grease all grease fittings on trip pins and king pin/hinge.
SNOW PLOW OPERATION
Get the most out of your SnowDogg®Plow. Here are a
few tips from experts to help you maximize your plow’s
productivity whether you’re just plowing a driveway or
plowing a stadium parking lot.

13
Transporting Your Plow
• Raise your plow blade when transporting your plow.
Each truck is different and road conditions vary. Find a
height that is high enough to avoid ground contact, but
still allows air flow to your radiator and does not block
lights.
• Angle the plow blade (in either direction) to help air flow
to your radiator.
• Transport your V plow in the “V” position (both wings
retracted) to decrease the load on the truck and decrease
the plow width for easier maneuvering.
• Always keep an eye on the temperature. If you see your
temperature climbing pull over to adjust the plow position.
A small position change can make a large difference.
• Always keep the plow in the same position while
transporting. DO NOT move the plow during transit. Turn
your controller OFF to ensure you do not move the plow
accidentally.
• Take some time to get used to maneuvering your vehicle
with the plow mounted. Blade guides can help you with
visual cues; but practice, experience, and time will help
you maneuver with ease.
Plow Smart
• Always wear a seat belt while plowing.
• Inspect an area you plan on plowing prior to snowfall.
Make a note of potential hazards like sewer grates,
speedbumps, exposed pipes, and heaved concrete. Even a
light snow can hide obstacles that can damage your plow.
• DO NOT plow at speeds that exceed 14 MPH. If you
plow at speeds over 14MPH you may cause the truck
collision detection/avoidance system to activate, and
potentially cause airbag deployment.
• Effective stacking can be accomplished at slow speeds.
Slamming into piles at high speeds is reckless and can
cause needless damage to your plow or truck.
TACTICS FOR EFFECTIVE PLOWING
Windrowing
Windrowing is clearing a wide space (like a parking lot) by
creating “windrows” (long piles) of snow and continuing to
move them further over with repetitive passes. It allows you
to clear a parking lot from one side to another, with the large
piles of snow away from the building. Picture a row of cut or
mown hay or similar crop.
• Always plow closest to a building first so that you
gradually move the snow away from the building.
• Raise your blade and drive to a corner of the parking lot
closest to the building.
• Angle your blade away from the building, and drop the
blade to plow.
• As you plow straight across the parking lot, you will
throw snow forward and away from the building.
• Lift the blade to angle it in other direction, turn around,
and drop the blade to plow. Repeat.

14
Backdragging
Backdragging is lowering your plow blade over snow that
you want to move, and then dragging it backwards to move
it. It is especially useful for plowing driveways, cleaning up,
and clearing tight spaces.
To backdrag, simply pull up to a building, garage door, or
other obstacle with the plow raised. Drop the plow and
reverse several truck lengths. You can then back into the
cleared area and plow it out, or windrow the newly created
piles.
Stacking
SnowDogg®plows are ideal for stacking because they
feature a chain lift that allow the blades to rise as they go up
to a stack. However, only stack when necessary. Excessive
stacking is hard on your vehicle and your plow.
Lift the blade as you stack to avoid pulling snow down as
you reverse. Stacking should be done at slow speeds—you
do not need to slam into a stack. ALWAYS bring your truck
to a complete stop prior to shifting into reverse.
OTHER TIPS
Plow with the storm.
It’s much easier to continue to plow as the snow builds,
rather than waiting to plow at the end of the storm. Large
amounts of snow are hard to move, will take many passes,
and will ultimately hinder your productivity.
Do it right the first time.
Push all the snow where you need it to be the first time
around. If you let it sit wrong spot for too long it is likely to
freeze and make the next plowing very difficult. If you try
to “push back” ice banks that have formed from a previous
plowing, it will put a tremendous and unnecessary load on
your plow and truck. Take the time to get it all done right
while the snow is still fresh.
ADVICE FOR PLOWING IN DEEP SNOW
Use common sense to limit the load deep snow puts on your
plow and truck.
V Plow: V Plows are built to perform in deep snow. Cut a
“path” with your plow in V mode. If necessary lift the plow
to remove some of the snow. Once you have cleared a
path start to extend the wings to widen the cut. Then start
to windrow but only use a portion of blade. For example,
with 8 in. of snow, you should use no more than half of the
blade. Plowing full width in deep snow can damage your
transmission and possibly the blade.
Straight Blade: With the right technique, your straight
blade is ready to stand up to the deepest snow. Start to cut
a “path” by keeping your blade partially raised. Follow the
same steps as if you were to windrow, and with each pass
“scrape off” more snow until you’ve scraped to the ground.

15
Even trucks that have 4WD can get stuck in deep snow, so
make sure to be mindful of what you are driving into.
Always plow in float.
Float allows the plow to stay low and contour the ground.
When the plow is not in flow each obstacle and tripping
cause the plow to “yank” the lift chain. This puts undue
stress on the plow’s lift frame, mount, and the trucks frame.
Have good customer service.
Find out where your customer wants the snow to be piled.
Customers may need to be reminded that the snow must
go somewhere– so make sure they have a realistic idea of
where it can go safely. Snow should never block visibility or
access to important areas like fire hydrants, mailboxes, or
public easements.
Follow local regulations.
In most places snow cannot be pushed onto other property,
or onto public streets. In many municipalities snow cannot
be pushed across the street. Be sure to check local snow
regulations where you are conducting business. Remember,
it’s your name on the side of the truck.
LIGHT AIMING
1. Place the vehicle on a level surface 25 feet in front of a
matte-white screen, such as a white wall or garage door.
2. The snowplow should be mounted, with the blade raised
in transport position.
3. Check that the truck is in normal operating condition
with no flat tires, failed suspension components, and no
passengers.
4. Mark the vertical centerline of the vehicle headlights on
the screen (a line matching the height the of headlights from
the ground). Mark the horizontal centerline of the vehicle
headlights on the screen (lines matching the headlight
center to center distance).
5. The high intensity zone of the low beams should be just
below the horizontal line and the right of the vertical lines
(see diagram below). Adjust the headlight aim as required.
