Warning!

Snowplow Operation

BLIZZARD

Your snowplow is the most advanced and versatile straight blade on the
market. The easy-to-use joystick control allows you to automatically adjust
the plow blade into an infinite number of plowing positions. Review the
illustrations below for instruction on maneuvering your snowplow.

WARNING

To prevent accidental plow activation, turn
POWER switch to the “OFF” position when
not in use.
BLZ 1017

A. Lowered or Float Position
Pushing the joystick forward, toward the “Lower/
Float” designation on the label, will lower your
straight blade to the ground. Pushing the joystick
ahead until the detent “locks” the control will allow
the snowplow to “float”, or follow the contour of
the ground when moving forward or backward.

B. Raised Position
Pulling the joystick back, toward the “Raise”
designation on the label, will lift your straight
blade off of the ground. To stop raising the plow,
simply return the joystick to its “neutral” or center
position. The snowplow has reached its maximum
raised position when the blade stops lifting –
return the joystick to its neutral position.

C. Angled Right Position
To angle your straight blade to the right, position
the joystick toward the “R” on the label. To stop
angling the plow, return the joystick to its “neutral”
or center position. The snowplow has reached its
maximum angled position when the blade stops
moving to the right side.

D. Angled Left Position
To angle your straight blade to the left, position
the joystick toward the “L” on the label. To stop
angling the plow, return the joystick to its “neutral”
or center position. The snowplow has reached its
maximum angled position when the blade stops
moving to the left side.

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

Assembly Instructions
Unpacking & Inspection
Date of Purchase

Dealer/Distributor

Your Blizzard straight blade 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 toll free at 1-888-680-8600.
Begin unpacking and inspection in the following order:

Telephone Number

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

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

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 three digits
and/or two letters in the the number indicated is
always the plow model 700LD, 760LD, 760 or 800
– and the entire seven (nine) digit number make
up the entire serial number. The shipping document is also attached to the end panel. Be sure to
retain this list for your records.

Unpacking & Inspection

Moldboard & A-Frame Assembly
1. Begin the moldboard assembly by positioning the PIVOT BEAM and
A-FRAME near the connecting points at the rear of the blade between
the two center support ribs. 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"-10 x 3" (2" shank) hex head cap screw
through each mounting hole and secure with a 3/4"-10 top lock nut.
Tighten each nut until it is snug with the pivot beam.

12-1/2"

CAUTION: Do not over tighten hex head nuts! Binding may
prohibit the pivot beam from moving properly on the plow.
Note: To aid in the remaining 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 (See the diagram to the right). Tighten both of the 1/2"-13
top lock nuts on the kickstand.
2. Position each ANGLE CYLINDER with the rod end of the cylinder
in the pivot beam and the hydraulic hose port facing away from the
A-frame. Secure the cylinder to the pivot beam with one 3/4" x 4-1/2"
CLEVIS PIN and one 1/4" x 1-1/2" HAMMERLOCK COTTER PIN.
Note: The hammerlock cotter pin will “lock” itself into place once the
head of the pin is struck. It is not necessary to bend the pin further
upon installation. 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.
3. 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. Note: All of the hydraulic adapters can be
found packaged with the manifold assembly. Reference the table on
page 33 for proper torque specifications. Each adapter should be
angled toward the top of the moldboard. Connect the 3/8" x 24" hydraulic
hose, labeled #1, to the driver’s side angle cylinder adapter. Attach the
3/8" x 24" hydraulic hose, identified by a #2, to the passenger’s side
angle cylinder adapter. Be careful not to overtighten the hose connections. Route both hoses over the top of each angle cylinder.
4. Next, remove both of the plastic dust caps from the HYDRAULIC
LIFT CYLINDER ports. Attach one 7/16"-20 x 7/16"-20 45˚ ADJUSTABLE ELBOW O.R.B. ADAPTER to the driver’s side port and one
7/16"-20 x 7/16"-20 MALE O.R.B. CONNECTOR ADAPTER to the
passenger’s side port. Once the adapters have been installed on the
cylinder, connect the HYDRAULIC HOSES. Note: Position the fittings
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 on the driver’s side of the
cylinder receives a 1/4" x 17" hose identified by a label containing the
number 3. Connect the 45˚ angle on the hose to the hydraulic adapter
on the cylinder. The male connector adapter on the passenger’s side
of the cylinder receives a 1/4" x 15" hose identified by a label containing the number 4. Tighten the 45˚ end of the hose to the hydraulic

Kickstand

The kickstand is mounted 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. The proper
height of your snowplow mounting points to level
ground should be set at 12-1/2".

5. Begin the draw latch installation by first removing the DRAW LATCH
MOUNT PIN & SPACER from the assembly. By removing this pin, the
INNER DRAW LATCH PLATES can swing free. Proceed to remove
the INNER DRAW LATCH PLATE LIFT CYLINDER MOUNT PIN.
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, we will shift our
attention to assembly of 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.
6. Each of the 4 HOSE PORTS on the HYDRAULIC MANIFOLD are
covered with stretch wrap. Remove the wrap and install the appropriate
fitting (illustrated on page7) 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 7).

7. 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.

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

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 the wire lead coils.
Doing so can cause a solenoid cartridge to bend, causing
the cartridge to stick when activated.
Moldboard & A-frame Assembly (cont.)

Apply Loctite®
To Pump Mount
Hardware Upon
Installation

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.
8. Once the pump and manifold assembly is in place, connect the
hydraulic hoses to their respective adapters on the manifold. Remember,
the labeling on the hydraulic hoses correspond with the stamped
numbers on the manifold.
Begin installing the hoses with the driver’s side raise cylinder hose (#3).
Attach the straight end of the hose to the 7/16"-20 x 9/16"-18 90˚
swivel elbow adapter on the manifold. Connect the passenger’s side
lower cylinder hose to Port #4. Loop the hose through the opening in
the A-frame and connect the straight end of the hose to the 7/16"-20
90˚ swivel elbow adapter. Run both angle cylinder hoses (#1 and #2)
over the A-frame angle and to their respective manifold ports. Note:
The lift cylinder hoses should be routed through the triangular openings
in the A-frame.

Use Loctite® on
Manifold Mount
Hardware

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" 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).

9. 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" 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 Aframe 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.
10. 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 5" 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.
11. 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 provided
at the top of the outside 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!

1. Begin the electrical assembly by connecting the RED POWER WIRE
from the PLOW ELECTRICAL HARNESS to the PUMP motor terminal
stud using the hardware provided on the pump.
2. Place one 3/8" INTERNAL/EXTERNAL TOOTH LOCK WASHER, the
BLACK GROUND WIRE (from the harness) and the RED GROUND
WIRE on the COIL WIRE HARNESS (from the manifold) over the
tapped hole on the pump and secure the ground using one 3/8"-16 x
3/4" hex head cap screw.
3. Remove the hex jam nut and external tooth lock washer from the
POWER HITCH CONNECT/DISCONNECT TOGGLE SWITCH and
insert it through the back of the mounting bracket on the A-frame. Align
the notch in the key washer on the switch to the notch on the bracket.
Replace the lock washer and jam nut and tighten until the switch is
firmly in place. Next, attach the connector on the plow harness to the
switch. Note: Use caution when making the connection. Switches can
break if done forcefully.
4. Continue the harness installation by connecting the PLASTIC FEMALE
ELECTRICAL CONNECTOR on the harness to the PLASTIC MALE
ELECTRICAL CONNECTOR found on the coil wire harness.
5. Finalize the harness installation by sliding the DIODE PACK over the
diode pack mount bracket located behind the connect/disconnect toggle
switch. Position the wire harness braid in the notch on the switch
bracket and secure it with a cable tie.The diode pack mount bracket
contains an extra hole for a cable tie. Use it to secure the diode pack.

The draw latch toggle switch installs through the
rear of the bracket with the protective hood. Align
the key washer with the slot cut in the bracket to
prevent the switch from turning. Secure the
switch with the hardware provided. Note: Use the
square notch in the bracket (below the protective
hood) to position the braided harness. Use another
cable tie to hold the harness against the bracket.

6. To install the PUMP & MANIFOLD COVER, align the notches in the
cover with the welded bolts on the A-frame brackets. Secure the cover
with two 3/8" FLANGED WING NUTS. Verify the cover is positioned
over the protective toggle switch hood. Pop the front of the cover on
the threaded stud and secure it with the remaining wing nut.
Congratulations! You have just completed building the finest snowplow
available! However, the vehicle wire harness still needs to be installed.
That is the focus of the second half of the electrical assembly instruction.

Electrical Assembly - Vehicle Harness

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.
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. 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 harness 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 9 TERMINALS, from the main lighting harness, into the
HEADLIGHT RELAY. See the illustration to the left. Connect the
GREEN & YELLOW wire, from the vehicle harness with the molded
power plug, to the remaining spade on the relay. Securely mount the
relay to the vehicle with the terminals facing down. Installing the relay
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 (see list to the right), 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. Find an accessible location for the PLOW HEADLIGHT TOGGLE SWITCH & BRACKET under the dashboard. Install
the headlight bracket using two self-drilling screws. Insert the toggle
switch through the bracket and secure it with the hardware provided.
Use the MALE 2-PIN POWER CONNECTOR to connect the toggle
switch to the vehicle wire harness.
First, insert the 24" GREEN/YELLOW GROUND LEAD into the
FEMALE 2-PIN POWER CONNECTOR (on the vehicle wire harness).
This lead should be grounded to the vehicle. Next, plug both of the
SWITCH LEADS into the toggle switch. Note: Both terminals should
be inserted into the spades on the same side of the switch. One
terminal should be positioned in the middle spade. See the illustration
to the right and on page 32. Plug both 2-pin power connectors together.

Insert one terminal into
the middle spade.

Remaining terminal connects
to either spade on the SAME
side of the switch.

Elec. Assem. - Vehicle Harness (Cont.)

12. Connect the RED POWER WIRE (with 10 AMP FUSE) to a switched
power source with a minimum of 10 amps. Note: The red power wire
MUST be fused and switched on and off with ignition. Secure all loose
wires under the dash.

Dome
Plug

Apply a thin bead of silicone around the inside
perimeter of the polyethylene dome plugs prior to
capping the light tower ends. The silicone will
help retain the dome plug inside of the headlight
mount tube.

13. Next, install the LIGHT TOWER. Position the tower arms into the
receiving pockets located on the undercarriage push beam. Align the
mounting holes in the light tower with those on the push beam and
insert two 1/2"-13 x 1-1/4" hex head cap screws. Secure the screws
with 1/2" washers and top lock nuts. See your local Blizzard Dealer
for complete installation instructions for your vehicle undercarriage.
14. 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 1/2" split lock washer and hex nut. Note: All snowplows are shipped with two BLACK DOME PLUGS that install at
either end of the light tower. For secure placement, apply a bead of
silicone around the perimeter of the plug prior to installation on 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.
15. Align the four mount holes on the JOYSTICK CONTROL with the
holes located on the JOYSTICK BENCH MOUNT PEDESTAL. Note:
The radius on the pedestal should face the dashboard. Secure the
joystick to the pedestal with four 8-32 x 3/4" machine screws provided.
Next, slide the VELCRO® STRAP through the slots cut in the pedestal.
The metal D-RING should be located on the side opposite of the radius.
Wrap the strap around the bench and fasten. Finally, connect the
white power connector from the vehicle wire harness to the connector
on the control station. The power switch on the joystick should be in
the “OFF” position.

Emergency 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 the emergency hitch pin. 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 shown in this illustration.

Testing The Snowplow

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.

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. Turn the POWER
SWITCH on the joystick in the cab to the “ON” position and turn the
vehicle ignition switch on. You now have power to the snowplow. Once
all of the hydraulic functions have been executed, the system will have
been filled with approximately 3 to 3-1/2 quarts of hydraulic oil.

2. Raise the DRAW LATCH on the snowplow by pushing and holding 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 draw latch will lower.
Refill the reservoir until the fluid is 3/4" from the top of the tank.
3. Position the vehicle such that the draw latch 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 14). Move the snowplow in position
by activating the draw latch connect switch and release.
WARNING: Always use caution when operating the draw
latch 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 warning may result in serious injury or death.
The draw latch 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 locked 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
power supply on the joystick should be in the “ON” position. Next, raise
the plow to its maximum height by pulling back (“RAISE”) on the joystick. Angle the snowplow to the left by moving the joystick toward the
“L” (left angle) on the label. If the plow function is slow or delayed, the
hydraulic fluid is filling the cylinder and replacing the air in the system.
Continue testing the remaining joystick 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.

Your Blizzard Straight Blade snowplow will use
approximately 3 to 3-1/2 quarts of Blizzard Rapid
Action Hydraulic Oil. Note: The part 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). See your local Authorized
Blizzard Dealer for price and availability.

Your Blizzard straight blade 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 33.
2. All hydraulic hoses and hydraulic hose adapters for wear and leaks.
See the recommended hydraulic adapter torque values on page 33.
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. A NLGI Grade 2 multipurpose 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. 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 35 for additional instructions.
11. 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.

1. Verify the port, O-ring, sealing surfaces, and threads are
clean and free of damage.

2. Lubricate 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 turns 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.
Sizes -02 through -08 are less tolerant to overtorque abuse. This will reduce the clamping force
resulting in loss of seal and reduction in flow.

2. Lubricate the threads and the O-ring with 10W hydraulic oil.
3. For an adjustable O.R.B., completely back-off the lock nut
and the washer.
4. Hand tighten the fitting until it contacts the port spotface.
Point the elbow or tee in the desired direction and hold.
5. Proceed to tighten to the proper specified torque value.
Note: Torque values specified are for threads lubricated
with 10W hydraulic oil.

Torque Specifications

Troubleshooting Guide
Prior to diagnosing your straight blade, 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

Pump will not run.

Plow wire harness may not be properly connected to the
vehicle wire harness.

Verify the wire harnesses are properly connected.
Review the instruction on pages 9-12.

Power or ground cables to the battery, pump or solenoid
may not be properly connected.

Properly connect all cables. Clean and lubricate with
dielectric grease. If power does not resume, check the
continuity of all cables to find the break.

Pump will not run, power to the solenoid.

The black ground wire and brown/white activation wire on
the solenoid are not properly connected.

Properly connect both cables. Test for power by initiating any joystick function except the float. Note: The
POWER rocker switch must be in the “ON” position to
properly test any plow function. If the solenoid is
grounded and no power exists, diagnose the plow &
truck wire harnesses.

Pump will not run with power to the solenoid.
Brown/white activation wire and ground are
properly connected.

The red, hot wire to the pump motor is not properly
connected.

Connect red wire and check the black ground wire. If
problem is not resolved, the solenoid could be inoperable or the pump motor may be worn. Replace the
solenoid if there is no power to it. Replace the pump
motor if it is receiving power.

Pump will not turn off. Do not allow the pump
motor to continuously run. Unplug both of the
harnesses until the pump can be tested or a
Blizzard Dealer can diagnose the problem.

Solenoid may be damaged.

Disconnect the brown/white activation wire from the
solenoid. If the problem is not resolved, replace the
solenoid.

Short in the joystick control or wire harness.

Disconnect the joystick in the cab. If the solenoid turns
off, there is a short in the electrical system.

Fluid level in the pump reservoir is low. Fluid is leaking.

Add fluid to within 3/4” from the top of the tank. Check
for leaks around the pump, manifold and cylinders.

System pressure may be set too low. Increasing the
pressure excessively will increase the amperage draw.
This could damage the vehicle wire harness.

Adjust the pressure. Remove the hex cap on top of the
pump and turn the screw clockwise. Proper system
pressure should be set at 2400 PSI. Test functions and
repeat procedure as needed.

Amperage from the vehicle’s alternator is too low.

Repair or replace vehicle alternator. System amperage
draw is 150 Amps at 1500 PSI.

Pump filter may be clogged.

Remove the pump tank and thoroughly clean the filter.

A-frame latch will not move.

Draw latch is binding the A-frame latch.

Lower the draw latch to relieve binding on the A-frame
latch and reposition the A-frame latch as needed.

Plow will not lift. Pump works properly.

Control station in the cab may not be properly connected.

Connect the power connector from the control to the
vehicle wire harness.

A-frame latch is in the (down) locked position.

Lift the A-frame latch into the raised position.

Diode pack may be corroded or could have failed.

Clean diode pack thoroughly and/or replace.

Pump runs but plow functions are slow.

Troubleshooting Guide (1 of 2)

Problem

Probable Cause(s)

Suggested Remedy

Plow will not lift. Pump works properly.
(Continued from page 34.)

Coils on the manifold may be damaged.

Remove both S6 & S7 coils from the cartridge valves.
Position a screwdriver inside of the coil and push the
draw latch connect/disconnect toggle switch upward.
The screwdriver should be magnetically drawn to the coil.
Replace the coil if there is no action.

Plow will not lift with magnification to the
S6 & S7 coils.

Hydraulic lock in the manifold. This occurs if the voltage is
too low on the coils – should be 11.8 volts.

Loosen cartridge valve S6 or S7 to relieve pressure and
retighten. DO NOT OVERTIGHTEN! Valves should be
torqued to a maximum of 24 ft. lbs.

Solenoid cartridge valve may be contaminated.

Remove any foreign objects that may be obstructing
proper valve operation. Replace if not operating properly
after cleaning.

Plow will not stay angled when plowing.

The angle pressure relief valve is set too low.
NOTE: Increasing the pressure relief valve will cause
damage to your plow. Do not set the pressure relief
greater than 3000 PSI (See illustration below)

Check the pressure relief by testing the valve inline with
the cylinder. Attach a tee fitting to the angle cylinder
hydraulic adapter and connect the hose and pressure
gauge to the tee. Push the plow against a solid object
and record the pressure reading. Note: The setting should
not exceed 3000 PSI.

Plow will not angle, pump works.

Review all probable causes above.

NOTE: Verify solenoids S3 & S4 for angle functions.

Plow lowers too slow.

Variable flow control valve is not adjusted properly.
(See illustration below)

Turn flow control valve counterclockwise in small increments and test. NOTE: Never make adjustments when
the plow is in the raised position! Fluid pressure will make
the valve difficult to adjust and serious injury or death can
occur from a falling plow.

Plow drops sporadically.

Variable flow control valve is opened too far.

Turn clockwise 1/16 of a turn and test. See warning above.

Headlights will not switch from the vehicle to
the snowplow.

No power or ground to the headlight relay.

Verify green/yellow (G/Y) wire for the ground is connected.
Verify black/white (BK/W) wire for the power is connected.
If both are connected properly, replace the headlight relay.

Should your snowplow develop other problems not indicated in the Troubleshooting Guide, contact your local dealer for technical assistance and/or replacement parts.
