Snowplow Operation 03

Snowplow Operation

Your Blizzard Power Plow snowplow is the most advanced and versatile
snowplow on the market. The easy to use controls allow you to automat­ically adjust the plow blade and wings into an infinite number of plowing
positions. Review the illustrations below to determine the best position for
your plowing needs.

A.

B.

C.

D.

A. Compact Position (8'-6" Blade Width)

•Primary position when transporting
the snowplow

•For use in heavy snow conditions with poor
visibility, initial clearing and tight quarters

• Ideal application: Residential driveways,

small roads

B. WidePass™ Position (11'-3" Blade Width)

•Primary position for clearing large surfaces

•For use in light snow conditions with good
visibility, final clearing and clean-up

• Ideal application: Large parking lots,

widening roadways

C. BucketBlade™ Position (9'-10" Blade Width)

•Primary position for transporting snow

•For use in initial clearing with decent visibility,
transporting large volumes of snow, final
clean-up

• Ideal application: Roadway intersections

D. WidePass™ Position Angled with

Wing Forward

•Primary position for accelerated angled plowing

•For use in directional plowing, cornering,
diverting snow away from objects or buildings

• Ideal application: Plowing adjacent to buildings,

driveway/road intersections

***** IMPORTANT *****
To prevent premature failure of the power
contactor (solenoid), initiate the plow function
and return the rocker switch and/or joystick to
its neutral or center position. DO NOT hold a
rocker switch and/or joystick in any position
that allows the pump to continuously run
after the main blade or wing has reached its
maximum degree of movement. This will
reduce the useful life of the solenoid.

04 Unpacking & Inspection

Assembly Instructions

Unpacking & Inspection

Your Blizzard Power Plow snowplow has been packaged to withstand
transit and weather related damage. Fully inspect all components upon
receipt of your plow. In the event of shipping damage or missing parts,
immediately contact our Customer Service Department at 1-888-680-8600.

Begin unpacking and inspection in the following order:

1. Remove the shipping document from the end panel of the pallet wrap.
Retain all documentation for your records.

2. All wood framing and polyethylene material should be removed from
the pallet for easy access to the snowplow.

3. Due to the odd shaped components and size of several assembly
parts, various cable ties and corrugated material are used for scratch
resistance and package orientation. Please remove these items prior
to assembly.

4. Place the main blade assembly on a flat, level surface.

Once you have inspected all parts and removed all packaging materials,
your snowplow is ready to be fully assembled.

Pallet Wrap End Panel

The tear resistant woven polyethylene pallet wrap
contains a moisture barrier to help protect all
packaged components and keep out the most
inclement weather during shipping and storage.
The end panel of the pallet cover contains impor­tant information regarding the snowplow model
and the plow’s serial number. Both of these num­bers are given together.The first four digits of the
number indicated is always the plow model –
8611 and the entire number sequence make up
the serial number. The shipping document is also
attached to the end panel. Be sure to retain this
list for your records.

Moldboard & A-frame Assembly 05

Moldboard & A-Frame Assembly

1. Begin the moldboard assembly by first removing each dust cap from
both of the SLIDE BOX CYLINDERS located at the center/rear of the
MOLDBOARD. Attach one 7/16"-20 x 9/16"-18 MALE O.R.B. CON­NECTOR to each of the retract ports (#7 & #10) and one 9/16"-18 x
9/16"-18 MALE O.R.B. CONNECTOR to each of the extend ports (#8
& #9). Review the diagram below. Note: All of the hydraulic adapters

can be found packaged with the manifold assembly. Reference the
table on page 20 for proper torque specifications.

2. Connect the hoses to each of the hydraulic adapters on the cylinders.
Por ts #7 & #10 receive a 1/4" x 36" HYDRAULIC HOSE (P/N 60019).

Note: Review the label on each hose for the appropriate part number.

Por ts #8 & #9 receive a 3/8" x 36" HYDRAULIC HOSE (P/N 60224).

3. Next, position the PIVOT BEAM and the A-FRAME, near the mount
locations at the rear of the blade, between the two center support ribs.
Place the right and left group of hydraulic hoses (connected to the slide
box cylinders) through the 1-1/2" diameter rubber grommet openings
in the front face of the pivot beam. See the diagram to the right.

4. Position the pivot beam between the two support ribs until the con­necting points on the beam align with those on the plow. Insert one
3/4" DIA. x 3" CLEVIS PIN through each mounting hole and secure
them with one 1/4" DIA. x 1-1/2" COTTER PIN.

Note: Mount the kickstand to the end of the pivot beam (driver’s side)
using the 1/2"-13 x 4-1/2" bolt provided. The spring, bushing and lock
nut locate on the inside of the pivot beam. Review the diagram to the
right and on page 26. Upon installation, rotate the spring loaded kick­stand clockwise until it locks into place. Adjust the foot on the stand
arm so the height of the A-frame, at its mount points, is 12-1/2" to
level ground.Tighten both of the 1/2"-13 top lock nuts on the kickstand.

Note: To prevent the kickstand from hitting the ground before the
snowplow cutting edges, causing stress on the kickstand lock pin,
adjust the kickstand foot approximately 1/8" short of level ground.
This procedure will provide clearance for the kickstand when the
snowplow is lowered with the kickstand in the down position.

5. Position each ANGLE CYLINDER with the rod end of the cylinder
in the pivot beam and the hydraulic hose port facing away from the

The kickstand mounts to the side of the pivot
beam with one 1/2"-13 x 4-1/2" hex cap screw
and top lock nut. To pivot the kickstand, simply
pull the spring loaded leg out and rotate it until
the pin locks into place. The kickstand also has
an adjustable foot that can be moved to accom­modate varying vehicle heights. Adjust the kick­stand foot approximately 1/8" short of level ground.
This will prevent the kickstand from hitting the
ground before the plow cutting edges. The proper
height of your snowplow mounting points to level
ground should be set at 12-1/2".

Feed each group of hoses (two per side) through
the grommets in the pivot beam and up through
the openings in the A-frame. Positioning the hoses
through the pivot beam supports the hoses while
the snowplow is in use and prevents them from
dragging on the ground.

06 Moldboard & A-frame Assembly (continued)

A-frame. Secure the cylinder to the pivot beam with one 3/4" x 5"
CLEVIS PIN and one 1/4" x 1-1/2" cotter pin. Extend each cylinder
rod until the cylinder base mounting hole aligns with the hole on the
A-frame angle cylinder bracket. At this point, insert another clevis pin
and secure it with a cotter pin. Repeat the same installation for the
opposite angle cylinder.

6. Remove each dust cap from both of the hydraulic angle cylinder ports
and attach one 9/16"-18 x 9/16"-18 90˚ ADJUSTABLE ELBOW O.R.B.
ADAPTER to each port. Each adapter should be angled toward the
top of the moldboard. Connect one 3/8" x 26" hydraulic hose (P/N

60223) to each angle cylinder adapter. Be careful not to overtighten
the hose connections. Route both hoses over the TOP of each angle
cylinder. This will prevent them from hanging or being pinched.

7. Next, remove both of the plastic dust caps from the HYDRAULIC
LIFT CYLINDER ports. Attach one 9/16"-18 x 9/16"-18 45˚ ADJUST­ABLE ELBOW O.R.B. ADAPTER to the driver’s side port (base end)
and one 9/16"-18 x 9/16"-18 MALE O.R.B. CONNECTOR ADAPTER
to the passenger’s side port (rod end). Once the adapters have been
installed on the cylinder, connect the hydraulic hoses. Note: Position

the 45˚ fitting in the cylinder port such that the hoses install directly
in the center of the A-frame access holes. A hose installed too close
to the edge of the opening may work itself free with the operation of
the lift cylinder and/or movement of the plow. The 45˚ adapter receives

a 3/8" x 17" hydraulic hose (P/N 60273). Connect the 45˚ angle on the
hose to the hydraulic adapter on the cylinder. The male connector
adapter receives a 3/8" x 15" hydraulic hose (P/N 60274).Tighten the
45˚ end of the hose to the hydraulic adapter on the cylinder. Both
hoses should be routed through the triangular openings in the A-frame.

Position the plates on either side of the lift/lower cylinder rod and insert
the pin through the plates and cylinder rod. With the cylinder connected
to the inner draw latch plates, rotate the draw latch assembly toward
the draw latch mount holes on the A-frame. Align the holes in the outer
draw latch plate with those of the inner draw latch plates and the
A-frame. Note: The A-FRAME LATCH, located at the rear center of

the A-frame, should be raised up to insert the draw latch mount pin.
Pull the A-FRAME LATCH PULL PIN out and rotate the latch counter­clockwise if it is locked into position.Secure the assembly to the A-frame

by replacing the draw latch mount pin and spacer. Reset the A-frame
latch so the A-frame latch pull pin locks into place.

Once you have completed the draw latch installation, proceed to assemble
the manifold. The manifold, pump and coil harness have been joined
together at the factory; however, the manifold contains several components
that you will need to install prior to securing the assembly to the A-frame.

9. Each of the 8 HOSE PORTS on the HYDRAULIC MANIFOLD are
covered with stretch wrap. Remove the wrap and install the appropriate
fitting (illustrated below) in its respective port.

Note: All ports are identified by a stamped number on the manifold.
The numbers also identify the hydraulic functions, which can be ref­erenced on the label under the hydraulic pump and manifold cover
(see illustration on page 8).

Note: The gray arrows shown on the manifold illustration below
indicate the direction the 90˚ adapters should face to receive the
hydraulic hoses.

Hose P/N 60273 Port #3
Hose P/N 60274 Port #4
Hose P/N 60019 Ports #7 & #10*
Hose P/N 60224 Ports #8 & #9*
Note: See diagram on page 8.

Installing The Manifold Adapters

There are a total of 18 hydraulic adapters to
install. All of the adapters can be found packaged
with the manifold assembly. Remove the protective
stretch wrap from the manifold in a clean area.
DO NOT let any foreign objects enter into the
open ports. The valves can become contaminated
and greatly hinder the plow’s performance.
Review the table on page 20 for proper torque
specifications.

08 Moldboard & A-frame Assembly (continued)

10. Next, align the mount holes in the pump with the holes in the hinged
bracket, located on the A-frame. Note: To help facilitate the pump mount,

first angle the hinged bracket as needed and tighten the bracket
hardware, locking it in place.

CAUTION:When installing the manifold between the mount
brackets on the A-frame, hold the manifold at the sides of
the block. Never handle the manifold by coils. Doing so can
cause a solenoid cartridge to bend, causing the cartridge
to stick when activated.

Secure one 3/8"-16 x 3/4" hex head cap screw and 3/8" flat washer
through the top mount hole in the bracket and into the pump. Insert
one 3/8"-16 x 1-3/4" threaded stud and 3/8"-16 jam nylon insert lock
nut through the bottom mount hole in the bracket and into the pump.
The threaded stud should bottom out in the pump. Note: A medium

strength threadlocker, such as Loctite® 242® should be used on both
of the pump mount fasteners.This will help prevent the fasteners from
working free.

11. Once the pump and manifold assembly is in place, connect the
hydraulic hoses to their respective adapters on the manifold. Review
the label under the pump cover to identify which hoses connect to
each port. Note: All hoses, except #1 & #2 (angle cylinders) should

be routed through the triangular openings in the A-frame. Position
these hoses over the A-frame angle and to their respective manifold
ports. Note the positions for the rod- and base-end slide box hoses.

The hoses that operate the retract functions (rod) of the cylinders are
closest to the base of each cylinder. Likewise, the hoses that operate
the extend functions (base) of the cylinders are closest to the rod of
each cylinder. Review the diagram on page 5 and the hose installation
list on page 7.

When installing the manifold between the mount
brackets on the A-frame, DO NOT handle the
manifold by the coils. The solenoid cartridges
can bend, causing them to stick when activated.
Always carry the manifold by the sides of the
aluminum block.

A medium strength threadlocker, such as Loctite®
242®, should be used to properly secure the
mount hardware for the pump and manifold. This
will help prevent the hardware from working free
from vibration and plow use. Apply a liberal
amount of threadlocker to both threaded fasten­ers and the threads in the pump (top diagram).
The manifold receives two 3/8"-16 x 1-1/4" hex cap
screws— one on each side of the A-frame. Like­wise, use threadlocker on these fasteners and
the tapped holes in the manifold (bottom diagram).

12. Next, secure the manifold to the A-frame. Remove both 3/8" flat
washers, 3/8" split lock washers and 3/8"-16 x 1-1/4" hex head cap
screws from the manifold and align the mount holes with the A-frame
brackets. Position the DIODE PACK MOUNT BRACKET against the
outside of the A-frame bracket on the driver’s side. Note: Both of the
prongs should be facing up. Align the outside hole on the diode bracket
with the holes on the A-frame and manifold. Properly replace and
tighten all hardware. Note: A medium strength threadlocker, such as

Loctite® 242® should be used to secure the manifold mount fasteners.

13. Hook each EXTENSION SPRING to the receiving holes located on
the pivot beam and connect the opposite end of the spring to their
respective SPADE BOLTS. Install the 5/8"-11 x 6-3/8" spade bolts
through the EXTENSION SPRING MOUNTING ANGLE on the top rear
of the blade. Secure each spade bolt by placing one 5/8" flat washer
on the bolt and thread one 5/8"-11 nylon insert lock nut. Tighten each
lock nut until a piece of paper can pass between the 3th & 4th coils
on the spring.

14. Install the flexible BLADE GUIDES at each end of the moldboard.
Insert the 5/16"-18 x 1" hex head cap screw through the holes at the
top of the wing reinforcement rib. Tighten all screws using the nylon
insert lock nuts provided.

Congratulations! You have successfully completed half of the installation.
Don’t quit now, you’re nearly out of the garage!

Electrical Assembly - Vehicle Harness

CAUTION: Always perform the vehicle wire harness assem­bly with the vehicle off and the keys out of the ignition. Use
caution when testing the electrical wires for the vehicle’s
headlight functions.

1. Begin the installation of the electrical harness under the hood. Insert
the WHITE POWER CONNECTOR & RED POWER WIRE (with FUSE)
end of the harness through the driver’s side fire wall access panel into
the vehicle cab.Note:You may need to widen an opening or cut access
to the cab interior to facilitate the assembly. Loosely position the
remaining portion of the harness over the driver’s side fender well and
place the MOLDED RUBBER POWER CONNECTOR near the bumper.

Note: Keep the plow and vehicle rubber power connector pins lubri­cated with a liberal amount of dielectric grease. Always replace the
protective RUBBER WEATHER CAPS when the plow is disconnected
from the vehicle.

2. Next, attach the POWER CONTACTOR (SOLENOID) to the driver’s
side wheel well or engine fan guard using two 12-14 x 3/4" hex washer
self-drilling screws. Note: Some model vehicles provide mounting

locations for accessory components. Always mount the solenoid with
the terminals facing up.This will extend the useful life of the solenoid.

Connect the 24" BLACK GROUND WIRE to either small terminal on
the solenoid and attach the opposite end to the vehicle with one hex
washer self-drilling screw. Locate the BROWN/WHITE PUMP SOLE­NOID ACTIVATION WIRE on the wire harness and position the eyelet
over the remaining small terminal on the contactor. Secure it with the
hardware provided on the solenoid.

3. Proceed to connect the BLACK VEHICLE WIRE HARNESS GROUND
WIRE to the negative terminal on the vehicle’s battery. Cut the wire to
length and crimp a 3/8" DIA. END RING TERMINAL on the wire. It is
also recommended that the ring terminal be soldered. Note: The har-

ness should be secured to the vehicle prior to taking the necessary
measurement. Measure the distance needed for the RED POWER

WIRE to reach the solenoid and properly secure an end ring terminal
to it. Connect the power wire to either large terminal on the solenoid.

CAUTION: Do not fasten the wire harness to areas that come
in contact with moving engine parts or possess extreme
heat.The harness could become tangled and/or melt causing
electrical failure and vehicle damage.

4. Attach and solder an end ring terminal to both ends of the remaining
length of the red 4 gauge wire. Connect one end of the wire to the
open terminal on the solenoid and the remaining end to the positive
terminal on the battery.

5. With the vehicle harness secured to the truck, position the MAIN
LIGHTING HARNESS such that both of the large, gray VEHICLE
HEADLIGHT CONNECTORS are near the truck headlights and the
smaller, black PLOW HEADLIGHT CONNECTORS are near the grill
of the vehicle.

6. Plug the 3 TERMINALS (GREEN/YELLOW WIRES), from the vehicle
wire harness, into the BLACK HEADLIGHT RELAY RECEPTACLES
on the main lighting harness. Remove the white secondary lock from
each receptacle, plug one terminal into the remaining position on each
receptacle and reposition the secondary lock. With the terminals in
place, plug each HEADLIGHT RELAY into the receptacles. Securely
mount the receptacles to the vehicle with the terminal wires facing
down and the relays facing up. Installing the relays in this position will
allow moisture to drain from the relay.

7. Next, remove the front directional light assembly on the driver’s side
of the vehicle. Feed the VIOLET, turn light wire and GRAY, run light wire
from the main lighting harness through the opening in the directional
light housing. At this point, use a test light or ohm meter to determine
the proper wires in the vehicle’s electrical system to splice into. Once
you have identified the proper wires, position one end of the turn or
run light wire into a SPLICE LOCK CONNECTOR provided. Attach
the vehicle wire to the opposite side of the splice lock connector.
Complete the splice by pinching both wires together and locking the
connector. Repeat the splice procedure for the remaining wire. The
passenger’s side directional light assembly requires the same instal­lation; however, only one wire, the PINK, turn light, needs to be spliced.

8. Connect the vehicle headlights to the main lighting harness using a
HEADLIGHT ADAPTER KIT. Due to differences in the construction
of the adapter kits, and the various make and model vehicles Blizzard
snowplows are installed on, a headlight adapter kit is not packaged
with your snowplow. Contact your local Blizzard dealer to obtain the
appropriate adapter for your vehicle.

9. Begin the adapter kit installation by removing the existing vehicle head­light connector from the headlight. Attach the HEADLIGHT ADAPTER
CONNECTOR to the existing vehicle headlight connector. Next, plug
the BLACK, FIVE-PIN CONNECTOR on the headlight adapter into
the gray, five-pin connector on the vehicle wire harness. Lastly, plug the
HEADLIGHT ADAPTER CONNECTOR into the vehicle headlight re­ceptacle. Note: If more than one plug is present, match the colors of

each connector (ie gray to gray, black to black, Chevrolet daylight run­ning is clear to gray). Repeat the installation for the opposite headlight.

10. Once the headlight adapter connections are completed, proceed to
secure the braided harness to the vehicle. Safely route all harness
lengths around the engine components and attach them to the vehicle
with cable ties. Extend the PLOW HEADLIGHT CONNECTORS, from
the main lighting harness, through the grill of the vehicle and position
the HARNESS POWER PLUG and WEATHER CAP near the bumper.
Cable tie the power plug to the vehicle bumper or tow hook to keep
the harness from hanging too low.

11. Return to the driver’s side cab interior to install the remainder of the
vehicle wire harness. Connect the RED POWER WIRE (with 15 AMP
FUSE) to a switched power source with a minimum of 15 amps. Note:

The red power wire MUST be fused and switched on and off with
ignition. Secure all loose wires under the dash.

Snowplow Hitch Pin
& Hair Pin Cotter

In the event you should lose hydraulic power while
snowplowing, raise the snowplow into a pile of
snow and insert one of the two hitch pins provided
with your plow.The pin will lock the plow in a tem­porary raised position until proper service can be
performed to restore hydraulic power. Note: For
clarity, the draw latch is not illustrated.

The vehicle wire harness is packaged with three
12V quick connect, sealed headlight relays. The
relays install into the black receptacles located on
the main lighting harness. Review the diagram on
page 32.

Electrical Assembly - Vehicle Harness (cont.) 13

12. Next, install the LIGHT TOWER. Position the tower arms into the
receiving pockets located on the undercarriage. Each pocket has a
lock pin that secures both light tower arms. Pull out and twist each
handle to temporarily unlock the pins. Place the light tower into the
pockets and relock the pins. See your local Blizzard dealer for com­plete installation instructions for your vehicle undercarriage.

13. Proceed to install the PLOW HEADLIGHTS. Align one HEADLIGHT
BALL STUD MOUNT ADAPTER on the light tower tube with the
mounting hole and insert the threaded stud through each. Secure the
headlight with one 7/16" external tooth lock washer and hex nut.

Note: All snowplows are shipped with two BLACK VINYL CAPS that
install at either end of the light tower. Connect the terminals from the

plow lights to the terminals on the main lighting harness. Repeat the
installation for the opposite headlight.

14. Next, position the ROCKER SWITCH CONTROL STATION on the front
radius of the seat. Wrap the VELCRO® STRAP around the bench,
through the 2" metal D-ring and fasten. Finally, connect the white
power connector from the vehicle wire harness to the connector on
the control station. The power switch should be in the “MIDDLE” or
“OFF” position. Note: The operation of the draw latch can only be

controlled when the power switch is located in the “UP” position and
the “RAISE/LOWER” rocker switch is in the neutral or center position.
See the diagram below.

This completes the electrical assembly installation for the vehicle wire
harness and main lighting harness. You are now ready to perform all of
the test functions on the snowplow.

14 Testing The Snowplow

Your Blizzard Power Plow snowplow will use
approximately 4 quarts of Blizzard Rapid Action
Hydraulic Oil. Note: The par t number issued on

the quart bottle label has been changed to P/N

63070. Blizzard hydraulic oil is also available by

the case (P/N 63071), gallon (P/N 63072) or gallon
case (P/N 63069). See your local authorized
Blizzard dealer for price and availability.

Testing The Snowplow

1. Fill the HYDRAULIC PUMP FLUID RESERVOIR with BLIZZARD
SNOWPLOW RAPID ACTION HYDRAULIC OIL (P/N 63070) until it
is approximately 3/4" from the top of the tank. Replace the cap on the
reservoir. Proceed to remove the weather caps from each of the plow
and vehicle wire harnesses and connect the plugs. Start the vehicle
and turn the POWER SWITCH on the control station in the cab to the
“ON” position.You now have power to the snowplow. Once all of the
hydraulic functions have been executed, the system will have been
filled with approximately 4 to 4-1/2 quarts of hydraulic oil.

2. To raise the POWER HITCH on the snowplow, turn the power switch on
the control station to the “UP” or “ON” position. Note: The “RAISE/
LOWER” rocker switch must be in the neutral or center position for the
Power Hitch to operate. Push and hold the toggle switch on the A-frame
upward into the “CONNECT” position. Notice the action of the fluid in
the reservoir. By activating the initial hydraulic function, the fluid begins
to fill the system. Push and hold the toggle switch in the “DISCONNECT”
position, the Power Hitch will lower. Refill the reservoir until the fluid
is approximately 3/4" from the top of the tank.

3. Position the vehicle such that the Power Hitch is below the push beam
and the mounting points on the A-frame are in line with the mounting
points on the undercarriage. Pull out the A-FRAME LATCH PIN and
rotate the A-FRAME LATCH clockwise until the latch is resting on the
DRAW PIN (See diagram on page 16). Move the snowplow in position
by activating the Power Hitch connect switch and release.

WARNING: Always use caution when operating the Power
Hitch CONNECT/DISCONNECT switch. Keep your hands and
feet away from the operation of the draw latch and the main
blade. The action of the draw latch moves the snowplow in
position for proper attachment to the vehicle. Failure to
follow this caution may result in serious injury or death.

The Power Hitch will raise until it hits the push beam and the DRAW
LATCH FINGERS will pull the plow into the vehicle. The mounting
points on the plow and vehicle are now positively aligned. Rotate the
A-frame latch counterclockwise until the latch is in the raised position.

Note: The A-frame latch pin should always lock in place. Do not set
the pin past the lock point on the A-frame. Insert the two HITCH PINS

through the mounting holes on the A-frame and secure each with one
hair pin cotter.The snowplow is now securely mounted to the vehicle.

4. Return to the interior of the vehicle. With the plow securely in place, you
can now execute the remaining functions of the snowplow. The system
power on the control station should be in the “ON” position. Next, raise
the plow to its maximum height by pushing and holding the “RAISE”
rocker switch on the control station. Initiate the driver’s side wing by
pushing and holding the “LEFT WING EXTEND” rocker switch until the
wing pivots forward. Notice the staggered pace the wing extends.The
hydraulic fluid is filling the hose and replacing the air in the system.

Testing The Snowplow (continued) 15

Push and hold the “LEFT WING RETRACT” rocker switch to return the
wing. Continue testing the remaining rocker switch functions. Monitor
the fluid level in the reservoir and fill to 3/4" from the top of the tank if
needed. Also, look for any hydraulic fluid leaks around the manifold,
pump, hydraulic hoses and all cylinders.

5. Lastly, check that the vehicle and plow headlights are in proper work­ing condition including the turn signals. If necessary, adjust the plow
headlight beams with the plow in the raised position.

Congratulations on a successful assembly and installation! Once all of the
blade and electrical functions have been tested your Blizzard Power Plow
snowplow is ready for action. Should you need additional support during
a plow assembly or undercarriage installation, contact your local authorized
Blizzard dealer.

18 Regular Maintenance

Regular Maintenance

Maintenance Schedule

Maintenance Performed Date

Your Blizzard Power Plow snowplow has been designed for years of rugged,
dependable service with low maintenance. To ensure proper working condition,
follow the maintenance guidelines below and on the next page.

CAUTION: Always follow the maintenance guidelines in a timely
fashion. Failure to observe maintenance guidelines may result in
poor snowplow operation, increased component wear or possibly
lead to part failure.

Routinely inspect the following items – perform maintenance as needed:

1. All fasteners, pins, nuts and bolts for tightness. See the recommended
maximum bolt torque chart on page 20.

2. All hydraulic hoses and hydraulic hose adapters for wear and leaks. See
the recommended hydraulic adapter torque values on page 20.

3. All cylinders for leaks; inspect rod ends for corrosion and pitting.

4. Cutting edges and plow shoes for wear. Do not discard plow shoe washers.
These should be retained for different shoe adjustments.

5. Clean and lubricate all electrical plugs, headlight connections, ground and
battery cables, solenoid connections and switch connections to prevent
corrosion. Apply dielectric grease for every 25 hours of snowplow use.You
may need to grease more frequently depending on your plowing environment.

6. Lubricate all pins and bushings to prevent corrosion and to maintain con­sistent operation, including the A-frame latch. The inner slide boxes should
also be lubricated to provide free travel. A NLGI Grade 2 multi-purpose
lithium complex grease with molybdenum (MPGM) is recommended for
lubrication.

7. Clean and cover deep scratches or exposed metal with Blizzard Snowplow
white (P/N 61219) or black (P/N 63073) touch-up paint. Contact your local
Blizzard dealer for availability.

8. Check the hydraulic oil level in the hydraulic pump fluid reservoir. Fill the
fluid to within 3/4" from the top of the reservoir. Do not exceed this level.
Never mix different types of fluids. Contact your local dealer for replace­ment Blizzard Snowplow Rapid Action Hydraulic Oil (P/N 63070).

9. Check the trip spring adjustment. Properly adjusted tension will allow a
sheet of paper to pass between the 3rd and 4th coils of the spring.

10. Each wing uses one extension spring to help return it from the forward or
scoop position. Adjust the tension on the installed spring as needed or
install and optional second extension spring for increased return speed.

11. To adjust the snowplow drop speed, use the variable flow control valve
(FC) on the manifold (see label under pump & manifold cover). Turn the
dial on the valve clockwise to decrease the drop speed. Turn the dial
counterclockwise to increase the drop speed. See the Troubleshooting
Guide on page 38 & 39 for additional instructions.

12. Do not allow snow and ice to build-up on the pump and manifold cover.
Excessive build-up may cause bumper damage when the plow is raised.

Storing Your Snowplow 19

Storing Your Snowplow

Placing Your Plow In Storage

1. Position your plow on a flat, level surface for storage. Follow the dis­mounting procedure illustrated on page 16.

2. Pressure wash and dry the entire snowplow prior to placing in storage.

3. Apply a liberal amount of dielectric grease to all electrical plugs and
connections. Clean and install all dust caps.

4. Lubricate all exposed hydraulic cylinder rod ends with liquid white
lithium grease to prevent corrosion.

5. Lubricate all pins and bushings to prevent corrosion and to maintain
consistent operation, including the A-frame latch and inner slide boxes.
A NLGI Grade 2 multipurpose lithium complex grease with molybdenum
(MPGM) is recommended for lubrication.

6. Clean and cover deep scratches or exposed metal with Blizzard Snow­plow white (P/N 61219) or black (P/N 63073) touch-up paint. Contact
your local Blizzard dealer for availability.

7. Remove and properly discard the fluid from the pump reservoir. Clean
the pump filter and replace the hydraulic oil to within 3/4" from the top
of the reservoir. Changing the fluid annually will prolong the life of your
pump and manifold. Never mix different types of hydraulic oil. Contact
your local dealer for replacement Blizzard Snowplow Rapid Action
Hydraulic Oil (P/N 63070).

8. Cover the snowplow with a tarp if stored outside. This will protect your
plow from sun fading and inclement weather which can lead to
accelerated corrosion.

Removing Your Plow From Storage

1. Perform all regular maintenance indicated on the previous page.

2. If you have not replaced the hydraulic oil in the pump reservoir, it is
strongly encouraged that you do so prior to operating your plow. Pro­longed storage could result in condensation build-up.

3. Follow the mounting procedure illustrated on page 16.

4. Once the plow has been properly mounted to the vehicle and all
electrical connections have been made, initiate all of the functions of
the snowplow. Monitor the fluid level in the reservoir and fill to 3/4" from
the top of the tank if needed.

5. Adjust the snowplow headlights as needed.

Annual Fluid Replacement

Type & Quantity of Fluid Replaced Date

1. Make sure the tubing and threads are clean.

2. Lubr icate the threads with 10W hydraulic oil.

3. Hand tighten the nut/sleeve to appox. 30 in-lbs.

4. Make alignment marks on the nut and fitting.

5. Proceed to tighten to tur ns or ft-lb values.

6. When fully tightened make a 2nd set of align­ment marks at the fully tightened position.

Note: Torque values specified are for threads
lubricated with 10W hydraulic oil.

Troubleshooting Guide

Prior to diagnosing your Power Plow snowplow, verify that all connectors (plow and vehicle wire harness plugs, headlight
adapters, control box, fused hot lead, draw latch switch, solenoid ground wire connection, coil wire lead harness, plow
headlight harnesses) are free of corrosion and are well lubricated with dielectric grease. Insuring that all connectors are
in good working order will save time in determining your snowplow’s service needs.

Problem Probable Cause(s) Suggested Remedy

Plow will not lift. Pump works properly. Coils on the manifold may be damaged. Remove the S6 coil from the cartridge valve. Position a
(Continued from page 37.) screwdriver inside of the coil and push the draw latch
