WARNING
Many newer trucks are equipped with air bags. DO NOT
under any circumstances disable or remove or relocate
any sensors or other components related to the operation
of the air bags.
WARNING
Always follow the vehicle manufacturers
recommendations relating to snowplow installation. For
recommended vehicle models refer to the SnowDogg
Application Chart and Selection Guide.
WARNING
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, would
deploy the air bag.
WARNING
Make sure plow is properly attached before moving
vehicle.
WARNING
Do not move plow while servicing or place body parts
between or under plow parts while moving plow.
WARNING
When transporting, position plow so as not to block vision
or plow headlights.
WARNING
DO NOT change blade position when traveling.
WARNING
DO NOT exceed 40 mph when transporting plow.
WARNING
Do not exceed 10 mph when plowing.
WARNING
Always lower blade when vehicle is not in use.
WARNING
Read this manual carefully before operating this
snowplow.
CAUTION
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 distribu-
tion 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 acces-
sories are installed.
• If there is uncertainty as to whether available capacity
exists, the actual vehicle as configured must be weighed.

Mount/Dismount Instructions
Snowplow Mounting (fig. above)
1. Check that the pins are fully retracted. The foot
pedal should be pushed towards the truck and will
lock in the retracted position.
2. Drive in to the plow so that the cross bar on
the mount engages with the receiver notch on the
plow. Depending on the plow height the jack many
need to lowered or raised to fully engage.
3. Pull the foot pedal away from the truck to release
the pins.
4. Push up on the lift frame to engage the pins. To
verify the lift frame is fully connected, check to see
that the gold pins are visible from each side. Insert
the lock pin (or padlock) through the foot pedal and
pedal linkage.
5. Retract the jack enough to allow its removal.
Rotate the jack to disengage from the jack mount
plate.
6. Stow the jack on the stow plate located on the
driver’s side moldboard and insert the lock pin. The
jack may also be stored in the truck for added theft
prevention.
7. Connect both the lighting & hydraulic control
connectors.
Snowplow Dismount (fig. above)
1. Put the plow in float by holding the down button
for 1 second.
2. Press down on the chain lift to retract the lift
cylinder. The chain must have slack for ease of
plow removal.
3. Install the jack into the jack mount plate. This
will raise the lift frame prop.
4. Extend the jack enough to remove weight from
the plow mount pins.
5. Push on the foot pedal and the lift frame
towards the vehicle simultaneously. The pins will
retract and the lift frame will rotate forward to rest
on the lift frame prop.

SNOWPLOW ASSEMBLY
1. Flip up the upper lift frame and secure using eight 1/2" x 1-1/2" stainless steel hex cap screws, nuts and
washers (10c/d/e).
2. Attach the chain lift to the upper lift frame and lift cylinder using two 7/8" x 4" clevis pins and cotter
pins (10a/b).
3. Attach the moldboards to the lift frame kit using the hinge pin, washer, and cotter pin as shown. Check
that the moldboards rotate freely around the hinge pin.
4. Install the two cylinder rods to each moldboard half with the clevis pins, washers and cotter pins as shown.
5. Install the snow deflectors (if desired) by loosening the fasteners on the top of the moldboard. The end
two fasteners will need to be removed to slide the deflector between the black painted retainer strip & the
stainless steel skin. It may be necessary to clamp the skin in place to allow insertion of the deflector. After
the deflectors are in place replace and tighten all fasteners.
6. Install deflector as shown.
7. Connect hoses to mold board fittings. The hoses and fitting are color coded - verify that each hose is
connected to the correct fitting. Finger tighten the swivels and turn an additional 1/4 turn with a wrench.
This will correspond to a torque of ~20ft-lbs. DO NOT OVERTIGHTEN THE SWIVELS.
8. Install the blade guides using the included hardware kit.
9. Install the lights with the light kit hardware. Do not route the plow side light harness yet as the
Passenger and Driver side light connection will vary depending on the truck side installation. Do not tight-
en the light hardware yet, as they will need to be aimed.
10. The plow may now be set into mounting configuration – install the jack and level the plow to the prop-
er height for mounting to the truck.
VEHICLE SPECIFIC MOUNT INSTALLATION
1. Mount the truck undercarriage as shown in the undercarriage installation instructions. As with the
plow, all the fasteners should be checked on a regular basis.
VEHICLE SPECIFIC HEADLIGHT ADAPTER INSTALLATION
1. It may be necessary to remove vehicle headlights to access the truck light harness connectors.
2. Install the vehicle specific headlight adapters per included installation instructions.
3. Be sure to route wires and harnesses away from hot surfaces or moving parts.
CAUTION
For safety reasons, the blade drops very slowly on the plow as shipped. To adjust the drop speed of the blade use a flat
blade screwdriver and turn the lowering speed adjustment on the front of the hydraulic power unit counter clockwise. Turn it
clockwise to slow the blade drop speed. Do this only while the blade is dropped, and tighten the jam nut after adjusting.

716992140 Rev C
HARNESS INSTALLATION
The SnowDogg has two separate harnesses for ease of installation and troubleshooting – a control harness
and a light harness. They can be mounted separately. In the case of trucks with central hydraulics or
existing auxiliary lights, either harness can be omitted without affecting the functionality of the other system.
Control Harness
The plow side control harness has been preinstalled. The truck side control harness is routed through the
grill, by the battery, and through the firewall to the controller. It is preferable when possible to keep the
plow connector on the drivers side to make mount/dismount easier and faster.
Control Harness Diagram
CAUTION
Keep all connectors greased with dielectric grease on a regular basis to minimize corrosion & potential damage or wear to the pins.
It is critical that all electrical connections be tight and secure. Loose connections on the plow circuit can cause overheating,
component failure, or intermittent operation.
1. Route the CONTROL HARNESS through the truck grill, by the battery, and through the firewall. Some
trucks will require drilling a ø1.50" hole through the firewall, while some will have holes provided (usually
plugged). Check your truck Owner’s Manual for details. If the hole is drilled it is critical that a grommet be
used to prevent damage to the wire harness.
2. Mount the MOTOR RELAY in a convenient and secure location on the battery side of the vehicle using
the included self tapping screws.
3. The small RED WIRE from the CONTROL HARNESS is connected to a small terminal of the MOTOR RELAY.
4. The small BLACK WIRE from the CONTROL HARNESS has two leads – one is connected to the other

small terminal of the MOTOR RELAY. The other is connected directly to vehicle/chassis ground.
5. The large (4 gage) BLACK WIRE on the CONTROL HARNESS must be connected directly to the
NEGATIVE (-) battery terminal. A BATTERY TERMINAL ADAPTER may be required.
6. The large (4 gage) RED WIRE on the CONTROL HARNESS is connected to one of the large terminals on
the MOTOR RELAY.
7. The shorter red BATTERY CABLE is used to connect the other large terminal of the MOTOR RELAY
with the POSITIVE (+) terminal on the battery. A BATTERY TERMINAL ADAPTER may be required.
8. The CONTROLLER CONNECTOR is routed through the firewall. Wait to complete RELAY HARNESS
installation before further steps.
9. Connect the handheld controller and locate in a convenient location for the operator using the included
mounting bracket or Velcro.
10. Male spade connectors on the BLACK and RED/WHITE wires will be connected to the LIGHT
HARNESS in the next step.
Light Harness
1. Route the RELAY HARNESS through the grill (drivers side preferably) and place the RELAY MODULE
close to either the drivers or passenger side headlight (whichever is convenient).
2. A VEHICLE SPECIFIC HEADLIGHT ADAPTER for your plow should be installed between the OEM
HARNESS and HEADLIGHT on both the passenger and driver sides. The BROWN wire from the adapter
should be spliced into the PARKING light circuit. The PURPLE wire from your adapter should be spliced
into the TURN signal circuit.
3. Route and connect the 8-pin connectors on the RELAY HARNESS to the VEHICLE SPECIFIC
HEADLIGHT ADAPTERS. There is a LONG and SHORT cable on the RELAY HARNESS. The LONG
cable is for the far side of the vehicle. Both CABLES are identical. LEFT and RIGHT turn signals will be
determined prior to routing the LIGHT HARNESS on the plow.
4. The ORANGE and BLACK/WHITE wires on the RELAY HARNESS are connected to the RED/WHITE and
BLACK wires on the CONTROL HARNESS. Connect them as shown below – see the application guide for spe-
cific information on your vehicle. In the case of a standard ground vehicle (switched hot), connect the wires as
shown below for standard configuration. In the case of a switched ground vehicle, locate the gray wire with male/
female disconnected fittings (already connected). Disconnect the two halves. The male quick connect end of the
wire will not be used and may be taped off. The female end will be connected to the RED/WHITE wire from the

these connections once complete to seal against corrosion.
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.
NOTE: Snowplow installers must certify that installation conforms to federal motor vehicle safety standards.

Your plow and truck are now ready for operation. The hydraulic system has been filled at the factory and
should be fully operational. It is possible that agitation due to the shipping has introduce some air into the
oil. When operating the plow for the first time some oil may exit the vent (by the coils). This should stop
once the plow is cycled and operational. Check all plow and light functions. If something is not working
correctly, reread the installation directions to make sure a step was not missed and check the schematics.
STORAGE
1. Before disconnecting the plow from your vehicle, fully compress the lift cylinder
2. Disconnect the plow from your vehicle
3. Coat all electrical connection points with dielectric grease
4. Repair/touch up any chipped paint or rusted areas
5. Apply a coat of oil or grease to all exposed chrome (on angle and lift cylinders)
6. Grease all grease fittings on trip pins and king pin
REMOVAL FROM STORAGE
1. Check all fasteners and hydraulic fittings for tightness.
2. Replace any cracked hydraulic hoses
3. Coat all electrical connection points with dielectric grease
4. Connect plow to vehicle
MAINTENANCE
The SnowDogg line of plows has been simply designed for reliable service. In order to ensure the
reliability of your plow, observe the following maintenance items and regularly inspect:
• Fasteners and retaining devices for proper installation and tightness.
• Hydraulic cylinders for damage, pitting or leakage
• Hydraulic hoses for wear, damage or leakage. Replace any damaged hose.
• All electrical connections for corrosion – apply dielectric grease as required
• Cutting edge wear
• Plow shoe wear
• Greasable fittings (2x trip pins and king pin)
HYDRAULIC SYSTEM
• All SnowDogg plows use SnowDogg brand Low-Temperature Hydraulic Fluid (P/N 16150010) available
from SnowDogg dealers.
• The reservoir should be filled through to top port until oil reaches the top port.
• Recheck and tighten all fittings and valves every season or as necessary. Vibration due to normal use
can cause fittings to loosen.
• Loctite or Teflon tape should not be used on any fittings or hoses. The only plugs where pipe sealant
may be used are the reservoir plugs.
• The reservoir should be drained and refilled every season to ensure that the oil remains free of water
and contanimants. If contaminants are known to be present, it is recommended that the reservoir be
removed and cleaned.
With proper maintenance and care your SnowDogg plow will provide years of trouble free service!

LIGHTING SCHEMATIC
PROPER OPERATION OF LIGHTS
Plow Parking Lights: On simultaneously with the Truck Parking Lights
Plow Turn Signals: On simultaneously with the Truck Turn signals / isolated by relays
Plow Headlights: On INSTEAD of Truck headlights. Truck and Plow headlights should NEVER be on at the same time.
NOTE
If the red/white wire is hooked straight to battery +12V, it will draw current at all times, draining the battery.
NOTE
Full schematics and pin out information can be found online at www.snowdoggplows.com
under Tech Support in the 16992900 service manual.
METHOD OF OPERATION
Headlights
The SnowDogg relay isolation module diverts switched power or ground for the plow high and low beams from the truck
harness to the snowplow lights when the plow is connected. There is no additional draw from the plow lights. The plow
headlights common uses the vehicle headlight harness common (+12V or ground) which is supplied through the light gray
wire. When the plow is disconnected power flows through the relay common to normally closed contacts to the truck headlights.

PLOWING TIPS
• Know the area you are plowing. Be aware of all hidden obstacles (pipes, drains, berms, etc.)
• Plow with the storm, do not let snow accumulate
• Always lower the plow blade when parking to minimize the risk of the plow dropping and to reduce the
load on the truck suspension.
• When transporting the plow – monitor coolant temperature. If the truck is running hot, adjust the plow
position to allow additional airflow to the radiator.
• Plowing at high speeds increases the potential for damage to your plow AND your truck
