MOLDBOARD & A-FRAME ASSEMBLY 1. Position the pivot beam and A-frame near the connecting points at the rear of the blade between the two center support ribs. Insert one 3/4" Dia. x 3" clevis pin through each mounting hole and secure with 1/4" Dia. x 1-1/2" cotter pin. NOTE: Mount the kickstand to the end of the pivot beam (driver’s side) using the 1/2"-13 x 4-1/2" bolt provided. The spring, bushing and lock nut are located on the inside of the pivot beam. Review the diagram to the right.
MOLDBOARD & A-FRAME ASSEMBLY 5. Remove the draw latch mount pin, spacer & cotter pin from the draw latch assembly. By removing this pin, the inner draw latch plates can swing free. Remove the inner draw latch plate lift cyl. 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.
MOLDBOARD & A-FRAME ASSEMBLY 7. 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. Appl y Loctite 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 coils.

ELECTRICAL-VEHICLE SIDE CAUTION: Always attach the vehicle 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. INSTALLATION INSTRUCTIONS 1. Insert the connector end of the harness through the driver’s side firewall access panel into the vehicle cab. Loosely position the remaining portion of the harness over the driver’s side fender well and place the plug end of the harness near the bumper.
ELECTRICAL-VEHICLE SIDE 10. Install the remainder of the vehicle wire harness to the interior of the cab. Find an accessible location for the plow headlight toggle switch & bracket under the dashboard. Install the headlight bracket using two selfdrilling screws. Insert the toggle switch through the bracket and secure it with the hardware provided. 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.

POWER HITCH™ INSTRUCTIONS Prior to operating your straight blade snowplow, review the Mounting and Dismounting Instructions label on the back of the driver’s side moldboard. NOTE: If at any time the Mounting and Dismounting Instructions label, or any other label attached to your snowplow become illegible, promptly replace them.
TESTING YOUR PLOW 1. Fill the hydraulic pump reservoir with BLIZZARD SNOWPLOW RAPID ACTION HYDRAULIC OIL until it is approximately 3/4" from the top of the tank. Replace the cap on the reservoir. Remove the weather caps from each of the plow and vehicle harnesses and connect the plugs. 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.
TESTING YOUR PLOW 4. Return to the interior of the vehicle. The system power on the control station should be in the “ON” position. Raise the plow to its maximum height by pulling the joystick back (or down). 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. Test the remaining functions of the snowplow.
MAINTENANCE MAINTENANCE Check fasteners for tightness. Torque to specifications. Check hoses for wear and leaks. Check cylinders for leaks; inspect rod ends for corrosion & pitting Lubricate all exposed cylinder rod ends with liquid white lithium grease to prevent corrosion. Check cutting edges and plow shoes for wear. NOTE: Do not discard plow shoe washers, these should be retained for different shoe adjustments. Clean and lubricate all electrical plugs and connections with dielectric grease.
TROUBLESHOOTING PROBLEM CAUSE Plow harness may not be properly connected to the vehicle harness. Pump will not run. Power or ground cables to the battery, pump or solenoid may not be properly connected. Pump will not run, power to the solenoid. The black ground wire and brown/white activation wire on the solenoid are not properly connected. Pump will not run with power to the solenoid. Brown/white activation wire and ground are properly connected.
TROUBLESHOOTING PROBLEM Plow will not lift. Pump works properly. Plow will not lift with magnification to the S6 coil. CAUSE Coils on the manifold may be damaged. Hydraulic lock in the manifold. This occurs if the voltage is too low on the coils –should be 11.8 volts. Solenoid cartridge valve may be contaminated. 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.
