SNOWPLOW ASSEMBLY
1.
Attach the chain lift to the upper lift frame and lift cylinder using two 7/8"x3.25" clevis pins and cotter pins.
2.
Attach the moldboard (2) to the lift frame using the trip pin hardware kit (3) as shown. Check that the mold-
board rotates freely around the trip pins.
3.
Install the two trip springs (4) using the trip spring hardware kit (5) as shown. Tension the springs until the coils
are approximately .030 apart. A playing card serves as an adequate measuring device. It is important that all
springs be at the same tension.
4.
Grease all greasable fittings (trip pins and king bolt).
VEHICLE SPECIFIC MOUNT INSTALLATION
1.
Mount the undercarriage as shown in the undercarriage installation instructions. As with the plow, all the fas-
teners should be checked on a regular basis.
CAUTION
For safety reasons, the blade drops very slowly on the plow as shipped. To adjust the drop speed of the blade
use a flat blade screwdriver and turn the lowering speed adjustment on the front of the hydraulic power unit
counter clockwise. Turn it clockwise to slow the blade drop speed. Do this only while the blade is dropped,
and tighten the jam nut after adjusting.
HARNESS INSTALLATION
The plow side control harness has been preinstalled. The truck side control harness is routed through the
grill, by the battery, and through the firewall to the controller. It is preferable when possible to keep the plow
connector on the drivers side to make mount/dismount easier and faster.
1.
Route the CONTROL HARNESS through the truck grill, by the battery, and through the firewall. Some trucks will
require drilling a ø1.50" hole through the firewall, while some will have holes provided (usually plugged). Check your
truck Owner’s Manual for details. If the hole is drilled it is critical that a grommet be used to prevent damage to the
wire harness.
2.
Mount the MOTOR RELAY in a convenient and secure location on the battery side of the vehicle using the includ-
ed self tapping screws.
3.
The small RED WIRE from the CONTROL HARNESS is connected to a small terminal of the MOTOR RELAY.
4.
The small BLACK WIRE from the CONTROL HARNESS has two leads – one is connected to the other small ter-
minal of the MOTOR RELAY. The other is connected directly to vehicle/chassis ground.
5.
The large (4 gage) BLACK WIRE on the CONTROL HARNESS must be connected directly to the NEGATIVE (-)
battery terminal. A BATTERY TERMINAL ADAPTER may be required.
6.
The large (4 gage) RED WIRE on the CONTROL HARNESS is connected to one of the large terminals on the
MOTOR RELAY.
7.
The shorter red BATTERY CABLE is used to connect the other large terminal of the MOTOR RELAY with the
POSITIVE (+) terminal on the battery. A BATTERY TERMINAL ADAPTER may be required.
8.
The CONTROLLER CONNECTOR is routed through the firewall. Wait to complete RELAY HARNESS installa-
tion before further steps.
9.
Connect the handheld controller and locate in a convenient location for the operator using the included
mounting bracket or Velcro.
10.
Male spade connectors on the BLACK and RED/WHITE wires are not used in this application and should be
taped/covered.
