SAFETY
SAFETY PRECAUTIONS
Improper installation and operation could cause personal injury, and/or equipment and property damage. Read and understand labels and the
Owner's Manual before installing, operating or making adjustments.
WARNING
Lower blade when vehicle is parked.
Temperature changes could change hydraulic pressure, causing the blade to drop unexpectedly or damaging hydraulic components. Failure to do this could result in serious personal injury.
WARNING
You can die or be seriously injured. Keep hands and feet away from hitch mechanism and snowplow blade when operating the
POWER HITCH™ arm. The action of the arm moves the snowplow toward the vehicle and into position for proper attachment.
WARNING
The driver shall keep bystanders clear of the blade when it is being raised, lowered or angled. Do not stand between the vehicle and the blade or within 8 feet of a moving blade. A moving or falling blade could cause personal injury.
WARNING
Do not exceed GVWR or GAWR including the blade and ballast. The rating label is found on the driver-side vehicle door cornerpost.
WARNING
To prevent accidental movement of the blade, always turn the ON/OFF switch to OFF whenever the snowplow is not in use. The control indicator light (touchpad only) will turn off.
WARNING
Remove blade assembly before placing vehicle on hoist.
CAUTION
Read Owner's Manual before operating or servicing snowplow.
CAUTION
Transport speed should not exceed 45 mph.
Further reduce speed under adverse travel conditions.
CAUTION
Plowing speed should not exceed 10 mph.
CAUTION
See your BLIZZARD ® outlet for application recommendations.
HYDRAULIC SAFETY
WARNING
Hydraulic fl uid under pressure can cause skin injection injury. If you are injured by hydraulic fl uid, get medical attention immediately.
• Always inspect hydraulic components and hoses before using. Replace any damaged or worn parts immediately.
• If you suspect a hose leak, DO NOT use your hand to locate it. Use a piece of cardboard or wood.
FUSES
The snowplow electrical and hydraulic systems contain several blade-style automotive fuses. If a problem should occur and fuse replacement is necessary, the replacement fuse must be of the same type and amperage rating as the original. Installing a fuse with a higher rating can damage the system and could start a fi re. Fuse Replacement, including fuse ratings and locations, is located in the Maintenance
Section of this Owner's Manual.
Lit. No. B64090, Rev. 05 5 March 1, 2009
SAFETY
PERSONAL SAFETY
• Remove ignition key and put the vehicle in park or in gear to prevent others from starting the vehicle during installation or service.
• Wear only snug-fi tting clothing while working on your vehicle or snowplow.
• Do not wear jewelry or a necktie, and secure long hair.
• Wear safety goggles to protect your eyes from battery acid, gasoline, dirt and dust.
• Avoid touching hot surfaces such as the engine, radiator, hoses and exhaust pipes.
• Always have a fi re extinguisher rated BC handy, for fl ammable liquids and electrical fi res.
FIRE AND EXPLOSION
VENTILATION
WARNING
Vehicle exhaust contains lethal fumes.
Breathing these fumes, even in low concentrations, can cause death. Never operate a vehicle in an enclosed area without venting exhaust to the outside.
BATTERY SAFETY
CAUTION
Batteries normally produce explosive gases which can cause personal injury. Therefore, do not allow fl ames, sparks or lit tobacco to come near the battery. When charging or working near a battery, always cover your face and protect your eyes, and also provide ventilation.
Batteries contain sulfuric acid which burns skin, eyes and clothing.
Disconnect the battery before removing or replacing any electrical components.
WARNING
Gasoline is highly fl ammable and gasoline vapor is explosive. Never smoke while working on vehicle. Keep all open fl ames away from gasoline tank and lines. Wipe up any spilled gasoline immediately.
Be careful when using gasoline. Do not use gasoline to clean parts. Store only in approved containers away from sources of heat or fl ame.
CELL PHONES
A driver's fi rst responsibility is the safe operation of the vehicle. The most important thing you can do to prevent a crash is to avoid distractions and pay attention to the road. Wait until it is safe to operate
Mobile Communication equipment such as cell phones or two-way radios.
NOISE
Airborne noise emission during use is below 70 dB(A) for the snowplow operator.
Lit. No. B64090, Rev. 05 6 March 1, 2009
VEHICLE APPLICATION INFORMATION
CAUTION
See your BLIZZARD ® outlet for specifi c vehicle application recommendations before installation. The Undercarriage Selection
Guide has specifi c vehicle and snowplow requirements.
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 cornerpost of the vehicle) and the front and rear weight distribution ratio. In some cases, rear ballast may be required to comply with these requirements.
• BLIZZARD Undercarriage Selection Guide is based on available vehicle capacity for snowplow equipment on a representative vehicle equipped with options commonly used for snowplowing and with 300 lb of front seat occupant weight.
• Weights of front seat occupants can be adjusted above 300 lb but vehicle with snowplow must not exceed vehicle GVWR or GAWR.
• In some cases there may be additional limitations and requirements.
• Installation, modifi cation and addition of accessories must comply with published
BLIZZARD recommendations and instructions.
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 confi gured must be weighed.
BALLAST REQUIREMENTS
Position and secure ballast as close to the tailgate
as possible.
Ballast (additional weight) is an important part of qualifying vehicles for snowplow eligibility. Rear ballast must be used when necessary to remain in compliance with axle ratings and ratios as specifi ed by the vehicle manufacturer.
If ballast is required, it is important that it be secured properly behind the rear axle. A ballast retainer kit is available from your BLIZZARD outlet, PN 62849.
NOTE: The ballast retainer kit is for snowplow vehicles requiring ballast. See your BLIZZARD outlet for the correct amount of ballast required.
Include the weight of the retainer as part of the ballast requirement. Sand bags are recommended for use as ballast.
NOTE: Ballast recommended and its weight calculations assume the entire width of the bed is fi lled as close to tailgate as possible.
Lit. No. B64090, Rev. 05 7 March 1, 2009
OPERATION
Your snowplow is the most advanced and versatile straight blade on the market. The easy-to-use controls allow you to automatically adjust the snowplow blade into an infi nite number of plowing positions. Review the illustrations below for instruction on maneuvering your snowplow.
A.
B.
C.
A. Lowered or Float Position
Pushing the joystick forward, toward the
"Lower/Float" designation on the label, or pushing the D button on the touchpad will lower your straight blade to the ground. Pushing and momentarily holding the control in this position will allow the snowplow to "fl oat," 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, or pushing the U button on the touchpad will lift your straight blade off of the ground. To stop raising the snowplow, simply return the joystick to its "neutral" or center position or release the touchpad button. The snowplow has reached its maximum raised position when the blade stops lifting.
C. Angled Right Position
To angle your straight blade to the right, position the joystick toward the "R" on the label or push the R button on the touchpad. To stop angling the snowplow, return the joystick to its "neutral" or center position or release the touchpad button.
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 or push the L button on the touchpad. To stop angling the snowplow, return the joystick to its "neutral" or center position or release the touchpad button.
The snowplow has reached its maximum angled position when the blade stops moving to the left side.
NOTE: To prevent premature failure of the power contactor (solenoid), return the joystick to its neutral (center) position or release the touchpad button immediately after the blade reaches the limit of any position. Continuing to hold the control after the blade has reached the limit of movement in any position will reduce the life of the solenoid.

3. 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 a 3/4" x 5" clevis pin (B41051) and a
1/4" x 1-1/2" cotter pin (B61357). Extend each cylinder rod until the cylinder base mounting hole aligns with the hole on the A-frame angle cylinder bracket. Insert another clevis pin and secure it with a cotter pin.
4. Remove the dust cap from both of the hydraulic angle cylinder ports and attach one 9/16" 90° adjustable elbow ORB adapter (B60005) to each port. Each adapter should be angled toward the top of the moldboard. Connect one
3/8" x 24" hydraulic hose (B60091) to each angle cylinder adapter. Be careful not to overtighten the hose connections. Route both hoses over the
TOP of each cylinder. This will prevent them from hanging or being pinched. Tighten fi ttings and hoses per torque chart.
5. Remove the plastic dust caps from the hydraulic lift cylinder ports. Attach one 9/16" 45° adjustable elbow ORB adapter (B60272) to the driver-side port (base end) and one 9/16" x 9/16" male ORB connector adapter (B60007) to the passengerside port (rod end). Once the adapters have been installed on the cylinder, connect the hydraulic hoses. Tighten fi ttings and hoses per torque chart.
NOTE: Position the 45° fi tting in the cylinder port so 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 snowplow.
The 45° adapter receives a 3/8" x 17" hydraulic hose (B60273). 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 (B60274). Connect 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. Tighten fi ttings and hoses per torque chart.

Before drilling any holes, check the selected area for wires, hoses or other obstructions.
1. With the large plug on the electrical harness placed near the tow hook, under the bumper, route the harness over the driver-side fender well and to the fi re wall. Insert the connector end of the harness through an existing hole in the fi re wall and into the vehicle cab. If an access hole does not exist, drill an appropriately sized hole through the fi re wall in a convenient location away from sharp edges and hot or moving parts.
NOTE: Keep the snowplow plug and vehicle connector pins lubricated with a liberal amount of dielectric grease. Always replace the protective weather caps when the snowplow is disconnected from the vehicle.
the eyelet terminal onto it. Attach the eyelet to the remaining small terminal on the contactor. Secure it with the hardware provided on the solenoid.
NOTE: Do not fasten the 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.
3. Connect the vehicle harness ground wire to the
NEGATIVE (–) terminal on the vehicle's battery.
Cut the wire to length, and strip the end of the wire. Crimp and solder a 3/8" ring terminal on the wire.
NOTE: The harness should be secured to the vehicle prior to taking the necessary measurement.
2. Attach the power contactor (solenoid) to the driver-side wheel well or engine fan guard using
#12 x 3/4" self-drilling screws.
NOTE: Some model vehicles provide mounting locations for accessory components.
Always mount the solenoid with the terminals facing up, for extended solenoid life. Connect the 24" black ground wire to either small terminal on the solenoid and attach the opposite end to the vehicle with a self-drilling screw. Cut the brown/white pump activation wire on the harness to length. Strip the end of the harness, and crimp

7. Remove the front signal lamp assembly from both sides of the vehicle. On the driver's side, feed the violet (turn lamp) and gray (run lamp) wires from the main lighting harness through the opening in the signal lamp housing. Use a test light or ohmmeter to determine the proper wires in the vehicle's electrical system to splice into. Position one end of the turn or run lamp wire into the splice lock connector, and attach the vehicle wire into the opposite side. Complete the splice by pinching both wires together and locking the connector.
Repeat the splice procedure for the remaining wire.
8. Repeat Step 7 for passenger's side using the pink
(turn lamp) and gray (run lamp) wires.
9. Connect the vehicle headlamps to the main lighting harness using a light conversion harness kit. Due to differences in the construction of the kits, and the various make and model vehicles
BLIZZARD ® snowplows are installed on, a light conversion kit is not packaged with your snowplow. Contact your local BLIZZARD dealer to obtain the appropriate conversion harness kit for your vehicle.
10. Secure the braided harness to the vehicle.
Safely route all harnesses around the engine components and attach them to the vehicle with cable ties. Extend the snowplow headlamp connectors, from the main lighting harness, through the grille of the vehicle and position the harness power plug and weather cap near the bumper. Cable tie the plug to the vehicle bumper or tow hook to keep the harness from hanging too low.
CAUTION

Check the hydraulic fl uid level. Fill with fl uid to 3/4" from the top of the reservoir. Do not exceed this level. Never mix different types of fl uid.
Remove and properly discard the fl uid from the pump reservoir. Clean the pump fi lter and replace the hydraulic fl uid to within 3/4" from the top of the reservoir. Changing the fl uid annually will prolong the life of your pump and manifold. Never mix different types of hydraulic fl uid.
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.
Clean snow and ice build-up from the pump and manifold cover.
Pressure wash and dry the entire snowplow prior to storing.
Cover the snowplow with a tarp if stored outside. This will protect your snowplow from sun fading and inclement weather which can lead to accelerated corrosion.

** Amperage Draw specifi cations are based on snowplow lift operation, at a shop temperature of 65°F, using
BLIZZARD ® Rapid Action Hydraulic Fluid. Amperage will vary with temperature, fl uid viscosity and meter accuracy.
Deadheading a snowplow function will result in signifi cantly increased amperage.
Lit. No. B64090, Rev. 05 35 March 1, 2009
TROUBLESHOOTING
Pump will not run.
Pump will not run, power to the solenoid.
Problem
Pump will not run with power to the solenoid. Brown/white activation wire and ground are properly connected.
Snowplow harness may not be properly connected to the vehicle harness.
Power or ground cables to the battery, pump or solenoid may not be properly connected.
The black ground wire and brown/white activation wire on the solenoid are not properly connected.
Cause
The red, hot wire to the pump motor is not properly connected.
Pump will not turn OFF. Do not allow the pump motor to run continuously. Unplug the harness until the solenoid can be tested or a BLIZZARD the problem.
® outlet can diagnose
Solenoid may be damaged.
Short in the control or wire harness.
Solution
Verify the harnesses are properly connected.
Properly connect all cables. Clean and lubricate with dielectric grease. If power does not resume, check the continuity of all cables to fi nd the break.
Properly connect both cables. Test for power by initiating any control function except FLOAT. NOTE:
The POWER rocker switch must be in the "ON" position to properly test any snowplow function.
If the solenoid is grounded and no power exists, diagnose the snowplow and truck harnesses.
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 the pump.
Replace the pump motor if it is receiving power.
Disconnect the brown/white activation wire from the solenoid. If the problem is not resolved, replace the solenoid.
Disconnect the control in the cab. If the pump turns
OFF, there is a short in the electrical system.
Fluid level in the pump reservoir is low. Fluid is leaking.
Add fl uid to within 3/4" from the top of the tank.
Check for leaks around the pump, manifold and cylinders.
Pump runs but snowplow functions are slow.
System pressure may be set too low. Increasing the pressure excessively will increase the amperage draw. This could damage the vehicle 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.
A-frame latch will not move.
Amperage from the vehicle's alternator is too low.
Pump fi lter may be clogged.
Draw latch is binding the A-frame latch.
Repair or replace vehicle alternator. System amperage draw is 135A (145A for 760LT) at
1500 psi.
Remove the pump tank and thoroughly clean the fi lter.
Lower the draw latch to relieve binding on the
A-frame latch and reposition the A-frame latch as needed.
Connect the power connector from the control to the vehicle harness.
Snowplow will not lift. Pump works properly.
Control station in the cab may not be properly connected.
A-frame latch is in the (down) locked position.
Diode loop harness may be corroded or could have failed.
Lift the A-frame latch into the raised position.
Clean diode loop harness thoroughly and/or replace.
Coils on the manifold may be damaged.
Remove the S6 coil from the cartridge valve.
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.
Lit. No. B64090, Rev. 05 36 March 1, 2009
TROUBLESHOOTING
Snowplow will not angle, pump works.
Problem
Snowplow will not lift with magnifi cation to the S6 coil.
Snowplow will not stay angled when plowing.
Snowplow lowers too slowly.
Snowplow drops sporadically.
Headlamps will not switch from the vehicle to the snowplow.
Cause
Hydraulic lock in the manifold.
This occurs if the voltage is too low on the coils–should be
10 volts.
Solution
Loosen cartridge valve S6 to relieve pressure and retighten. DO NOT OVERTIGHTEN! Valves should be torqued to a maximum of 24 ft-lb.
Solenoid cartridge valve may be contaminated.
Remove any foreign objects that may be obstructing proper valve operation. Replace if not operating properly after cleaning.
The angle pressure relief valve is set too low. NOTE: Increasing the pressure relief valve will cause damage to your snowplow. Do not set the pressure relief greater than
3000 psi.
Review all probable causes above.
Check the pressure relief by testing the valve inline with the cylinder. Attach a tee fi tting to the angle cylinder hydraulic adapter and connect the hose and pressure gauge to the tee. NOTE: The setting should not exceed 3000 psi.
NOTE: Verify coils S3 and S4 for angle functions.
Variable fl ow control valve is not adjusted properly.
Review all probable causes for snowplow will not lift.
WARNING: Snowplow can fall suddenly. You can die or be seriously injured. Drop snowplow to ground before adjusting fl ow control.
Turn fl ow control valve counterclockwise in small increments and test.
Verify S5 coil (fl oat) or S5 and S8 coils (disconnect) for magnetism.
Variable fl ow control valve is opened too far.
No power or ground to the headlamp relay.
WARNING: Snowplow can fall suddenly. You can die or be seriously injured. Drop snowplow to ground before adjusting fl ow control.
Turn clockwise 1/16 turn and test.
Verify the headlamp/ground relay connector is connected. If the connector is properly attached replace the headlamp relay(s).
