Plow Assembly & Adjustments
Nite Saber LED LightsNite Saber LED Lights
See seperate Nite Saber LED instructions for further information.
Mount the lights as shown below.
Connect both male ends from the snow plow light to the female ends on
the Plow Side Harness. Ensure all wiring harnesses are secured against the
lift frame.
Check snow plow lights and blinkers to ensure proper operation. If operat-
ing in reverse (i.e. driver side blinking instead of passenger side), reverse the
harness connections.
Note: All electrical connections should have both ends coated with a dielec-
tric grease (Meyer Part # 15632) prior to nal installation. This will ensure a
good connection and help in preventing corrosion.

Attach Eye Bolts to Moldboard and Trip Springs to Pivot Bar, making
certain locknuts are positioned as shown below.
Make certain each Eye Bolt is in a vertical position as shown below so that
the Eye Bolt and Trip Spring hinge properly when the Moldboard trips.
Note: Proper tension is attained when the Trip Spring coils just begin to
seperate and then tightening top locknut four additional turns. Tighten
bottom locknut to secure Eye Boilt in positiion.
Install Eye Bolt Caps over exposed threads.

Plow Assembly & Adjustments
Lift ChainsLift Chains
Attach the Lift Chain to the Lift Arm through the two hooks on the lift
arm. Adjust the lift chain at the lift arm so that there are 2-3 links of slack.
This ensures that the plow blade will lift fully and be able to follow the
ground contour while plowing.
Drop Speed AdjustmentDrop Speed Adjustment
Drop Speed Adjustment: Loosen jam nut and turn knob clockwise to slow
the drop of the plow and counter clockwise to speed the drop of the plow.
Tighten jam nut.
Drop Speed Adjustment
