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.
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.
7/16" Hydraulic Lift / Lower Cylinder 7/16" The draw latch consists of a series of interconnected plates and pins that attach to the A-frame and the hydraulic lift cylinder. Hex Head Cap Screw (3/4"-10 x 4-1/2") or (3/4"-10 x 4") for 700LD & 760LD only Draw Pin To mount the straight blade, the A-frame latch should be lowered over the draw pin– this allows the draw latch to pull the plow into the undercarriage.
/16" 9/16" 9/16" 9/16" 90˚ Adjustable Elbow O.R.B. Adapter (Port #1) 7/16" Male Extra Long Elbow Adapter (Port #2) 9/16" 7/16" Male O.R.B. Connector Adapter & 90˚ Swivel Elbow Adapter (Ports #3 & #4) Note: The gray arrows shown on the manifold illustration above indicate the direction the 90˚ adapters should face to receive the hydraulic hoses.
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.
Electrical Assembly - Plow Harness 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.
A Electrical Assembly - Vehicle Harness B 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.
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.
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.
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.
Mounting & Dismounting Instructions Prior to operating your straight blade, review the Mounting & Dismounting Instructions label at the driver’s side rear of the moldboard (shown below). MOUNTING & DISMOUNTING INSTRUCTIONS TM A-Frame Latch Lock Pin MOUNTING 1. Position vehicle close to the plow and align mounting points on the undercarriage and A-frame. Verify that the plow kickstand is in the lowered position. Turn vehicle ignition off. 2.

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 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.
