Lift Frame Side Plate Installation Procedure:

1. Install Mount Kit on vehicle referring to the Mount Kit installation instructions. Wire vehicle

referring to pages 7 & 8 for detailed Harness & Control System installation information.

2. With vehicle parked on level ground and properly ballasted for snow plow use, measure the

distance from the ground up to the centerline of the latch bar on the receiver as shown.

3. Once “X” dimension is determined, use the application chart below to determine which hole

locations to use when attaching the Lift Frame to the Side Plates

Important:

This is a general guideline to help make the assembly process easier. Due to great

variations in suspension, tires, age of vehicle etc. it may be necessary to change the

Side Plate positions after Plow assembly is attached to the vehicle.

Jack Adjustment Procedure:

With the Lift Cylinder & Jack fully retracted, top off the Pump Reservoir. It may be necessary to run the Jack

for 10 cycles as a break-in period. During the break-in period check carefully that the Jack RETRACTS

FULLY AGAINST THE BELLY PAN OF THE A-FRAME. If the Jack Leg Does Not retract fully, remove the A-

Frame Cover and manually adjust the tension on the Jack Return Spring using a 1 1/8” open end wrench.

The Jack Return Spring is located forward of the pump in the A-Frame pump cavity. A 3/4” hex nut holds

tension on the spring. If more tension is required, tighten the hex nut against the spring. When adjusting the

spring tension, use full turn increments and test the function of the jack leg after each turn. DO NOT over

tighten the return spring.

If “X” is 16 3/4” and Above use Top holes.

If “X” is between 15 3/4“ to 16 1/2“ use Center holes.

If “X” is below 15 1/2” use Bottom holes.

Side Plate Application Chart

Once vehicle Mount Kit and Harness installations are complete, raise the Plow Assembly to the same level as the

Mount Kit Receiver. To accomplish this, drive truck close to Plow Assembly and attach the Harness Plug. Put “in-

cab” Control System into the “float” position and raise the Plow Assembly using the A-Frame Jack Switch to align

the rear of the Lift Frame with the Mount Kit Receiver. If necessary, readjust the Side Plate positions.
