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" DIA. x 3" CLEVIS PIN through each mounting hole and secure them with one 1/4" DIA. x 1-1/2" COTTER PIN.
Printed Label All of the hoses shipped with the snowplow contain a printed label (with a part number) applied to the hose. Install the following hoses to their respective ports on the manifold: Hose P/N 60294 Hose P/N 60296 Hose P/N 60293 Hose P/N 60295 Port #1 Port #2 Port #3 Port #4 6. Begin the draw latch installation by first removing the DRAW LATCH MOUNT PIN, SPACER & COTTER PIN from the assembly. By removing this pin, the INNER DRAW LATCH PLATES can swing free.
Installing The Manifold Adapters 7/16" 9/16" 90˚ Adjustable Elbow O.R.B. Adapter (Ports #1, #3 & #4) 2 There are a total of 4 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 33 for proper torque specifications.
Use Loctite ® On All 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 all threaded fasteners and the threads in the pump and manifold. Both the pump and manifold receive two 3/8"-16 x 1-1/4" hex cap screws—one on each side of the A-frame and two into the pump.
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. Note: The red power wire contains an end ring terminal too large for the pump motor stud. Remove the end ring terminal from the harness and replace it with the 1/4" DIA. END RING TERMINAL located on the pump motor terminal stud. 2.
Electrical Assembly - Vehicle Harness B A C D Heavy-Duty Power Contactor (Solenoid) There are four wires that need to be attached to the power contactor: (A) Red Power Battery Wire (B) Vehicle Wire Harness Red Power Wire (C) 24" Black Ground Wire (D) Brown/White Pump Solenoid Activation Wire 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.
6. Plug the HEADLIGHT GROUND/RELAY (BLACK & GREEN/YELLOW) CONNECTOR, from the vehicle wire harness, into the connector on the main lighting harness. With the connection made, 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.
Insert one terminal into the middle spade. Remaining terminal connects to either spade on the SAME side of the switch. 12. Find an accessible location under the dashboard for the PLOW HEADLIGHT TOGGLE SWITCH & BRACKET. 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.
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 1-1/2 to 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. Push and hold the toggle switch on the A-frame upward into the “CONNECT” position.
Power Hitch™ Instruction Prior to operating your straight blade, review the Mounting & Dismounting Instructions label at the driver’s side rear of the moldboard (shown below).

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 with magnification to the S6 coil. 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 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.
