WARNING/CAUTION & INSTRUCTION LABELS

Become familiar with and inform users about the warning and instruction labels on the back of the blade.

NOTE: If labels are missing or cannot be read, see your sales outlet.

April 1, 2006 4 Lit. No. B64090, Rev. 00

WARNING

Crush hazard.

Keep feet clear.

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.

CAUTION

Read Owner's Manual before operating or servicing snowplow.

CAUTION

Transport speed should not exceed 45 mph. Reduce speed under adverse travel conditions.

CAUTION

Plowing speed should not exceed 10 mph.

CAUTION

See your BLIZZARD® outlet for application recommendations.

CAUTION

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

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

Remove blade assembly before placing vehicle on hoist.

HYDRAULIC SAFETY

WARNING

Hydraulic fluid under pressure can cause skin injection injury. If you are injured by hydraulic fluid, 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 electrical and hydraulic systems contain several automotive blade-style 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 fire.

Lit. No. B64090, Rev. 00 5 April 1, 2006

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-fitting 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.

FIRE AND EXPLOSION

WARNING

Gasoline is highly flammable and gasoline vapor is explosive. Never smoke while working on vehicle. Keep all open flames away from gasoline tank and lines. Wipe up any spilled gasoline immediately.

BATTERY SAFETY

CAUTION

Batteries normally produce explosive gases which can cause personal injury. Therefore, do not allow flames, 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.

NOISE

Airborne noise emission during use is below 70 dB(A) for the snowplow operator.

Be careful when using gasoline. Do not use gasoline to clean parts. Store only in approved containers away from sources of heat or flame.

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.

April 1, 2006 6 Lit. No. B64090, Rev. 00

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 plow blade into an infinite number of plowing positions. Review the illustrations below for instruction on maneuvering your snowplow.

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 "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, or pushing the "U" button on the touchpad will lift your straight blade off of the ground. To stop raising the plow, 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 plow, 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 plow, 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.

UNPACKING & INSPECTION

Blizzard Model 800 HD

060216650000B0800

Serial Number

Model

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 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.

Serial Number Labels

The serial number label on the back of the blade (driver side) contains important information about the snowplow. The serial number is displayed directly above the bar code, and the model information is above the serial number. The first six digits in the serial number represent the manufacture date of the snowplow. This date is formatted "yymmdd", in the example below, the manufacture date would be February 16, 2006. A similar label can also be found on the hydraulic unit. The manufacture date is, again, the first six digits of the serial number. Be sure to note both serial numbers in the area at the bottom of the preceding column.

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

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"-18 x 9/16"-18 90° adjustable elbow O.R.B. 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 over tighten the hose connections. Route both hoses over the TOP of each cylinder. This will prevent them from hanging or being pinched. Tighten fittings and hoses per torque chart.

5. Remove 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 (B60272) to the driver’s side port (base end) and one 9/16"-18 x 9/16"-18 male O.R.B. connector adapter (B60007) to the passenger’s side port (rod end). Once the adapters have been installed on the cylinder, connect the hydraulic hoses. Tighten fittings and hoses per torque chart.

NOTE: Position the 45° fitting 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 plow.

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 fittings and hoses per torque chart.

MOLDBOARD & A-FRAME ASSEMBLY

7. Assemble the manifold. The manifold, pump and coil harness have been connected at the factory; however, the manifold contains several components that you will need to install prior to securing the assembly to the A-frame. Each of the hose ports on the manifold is covered with stretch wrap. Remove the wrap and install the appropriate fitting in its respective port. Tighten fittings and hoses per torque chart.

8. Align the mount holes in the pump with the holes in the hinged bracket, located on the A-frame.

NOTE: Before mounting the pump, angle the hinged bracket as needed and tighten the bracket hardware to lock it in place.

Secure with 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 3/8"-16 x 1-3/4" threaded stud with 3/8"-16 locknut through the bottom mount hole in the bracket and into the pump. The threaded stud should bottom out in the pump.

NOTE: 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.

NOTE: A medium strength thread-locking compound should be used on both of the pump mount fasteners.

NOTE: The arrows shown on the manifold illustration indicate the direction the 90° adapters should be positioned to receive the hydraulic hoses.

NOTE: DO NOT let any foreign objects enter into the open ports. The valves can become contaminated and greatly hinder the plow’s performance. Torque to proper specifications.

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.

9. Connect the hydraulic hoses to their respective adapters on the manifold. Hose P/N B60091 Ports #1 & #2, Hose P/N B60273 Port #3 and Hose P/N B60274 Port #4. Tighten hoses per torque chart.

NOTE: Both lift cylinder hoses 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.
