OPERATIONAL TESTS AND ADJUSTMENTS
BLADE DROP SPEED ADJUSTMENT
NOTE: The quill on the top rear of the valve
manifold (see diagram) adjusts blade drop
speed. Turning quill too far in can slow raise
time and cause battery drain.
• Turn quill IN (clockwise) to decrease drop speed.
COUPLING LUG HEIGHT CHECK
1. Mount plow to vehicle. (See label on back of blade
or Owner’s Manual for mounting instructions.) Add
recommended ballast as found in Selection Guide.
2. Lift plow and move vehicle a minimum of 10 feet.
3. With the blade on a level surface:
• slack in lift chain
• rear ballast located behind rear wheels
• the center of the coupling holes (hitch pin shaft)
to level surface should measure 9-1/2" to 10-1/2".
• Turn quill OUT (counterclockwise) to increase
drop speed.
To obtain height, both Coupling Lugs and Link Arms
may be turned over to change height 1".
Quill
FINAL INSPECTION
1. Make sure all fasteners and hydraulic and
electrical connections are tight.
2. Check ram packing nuts for oil leakage. If
excessive leakage is observed, tighten the packing
nut 1/4 turn after you feel the nut contact the
packing.
NOTE: Do not over tighten packing nuts. Over
tightening affects cylinder operation and
shortens the life of the packing. A short period
of normal operation will allow chevron packings
to become saturated, and leakage will normally
stop. A small amount of leakage is necessary to
properly lubricate the cylinder rod.
Lit. No. 63244
NOTE: Coupling height must be 9-1/2" minimum
to allow stand to be pinned to frame.
4. Adjust chain slack with plow mounted to vehicle
and lift channel pushed all the way down. To adjust,
remove chain from hook, straighten chain and pull
tight. Rehook it to the lift channel. After chain is
hooked, it will have the correct amount of slack for
blade “float”. DO NOT remove chain from lift channel
when removing plow from vehicle.

OPERATIONAL TESTS AND ADJUSTMENTS
VEHICLE LIGHTING CHECK
Turn signals and parking lamps
2. Connect plow plug to vehicle harness connector.
Raise plow and aim plow headlamps according to
SAE J599 Lighting Inspection Code (See Service
Bulletin SP 608) and any state or local
regulations.
Parking lamps ON
• Both vehicle and plow parking lamps should be
on at the same time.
3. Check aim of vehicle headlamps with plow
removed.
1. Check the operation of vehicle and plow lights with
plow mounted to vehicle and all harnesses
connected.
Right turn signal ON
• Both vehicle and plow right turn signal lamps
should flash at the same time.
Left turn signal ON
• Both vehicle and plow left turn signal lamps
should flash at the same time.
Headlamps
4. When plow is removed from the vehicle, install plug
covers on vehicle harness connectors and insert
the plow plugs into the boot on the hydraulic unit.
After using the snowplow for 5-10 hours, retorque
all mount assembly fasteners.
Move vehicle headlamp switch to the ON position.
Connecting and disconnecting the 9-pin plow plug
from the vehicle harness connector should switch
between vehicle and plow headlamps as follows:
9-pin plow plug DISCONNECTED
• Vehicle headlamps should be on.
• Plow headlamps should be off.
9-pin plow plug CONNECTED
• Plow headlamps should be on.
• Vehicle headlamps should be off.
Dimmer switch should dim whichever headlamps are
operating. The high beam indicator on the dash
should light when either set of headlamps is on high
beam.
Solenoid Control or CabCommand Control
The control indicator light should light whenever the
control ON/OFF switch and the ignition (key)
switches are both turned ON. The plow plugs do not
need to be connected to the vehicle harness
connectors.
