TROUBLESHOOTING

PROBLEM
Plow functions will not work after all
connections are made or plow functions
are slow.
Plow functions start and terminate
suddenly.
Multiple valves function simultaneously.
Plow functions are reversed (i.e.
Driver's side wing extends when
passenger's side wing is activated from
the control.)
Both wings extend when the skid steer
hydraulics are turned on.
Plow angles only one way.
Wing will not stay angled when plowing.
Plow will not stay angled when plowing.
Wing will not move.
Wing will not move.
Plow will not angle.
Should your snowplow develop other problems not indicated, contact your local Dealer for technical assistance and/or
replacement parts.

CAUSE
S5 coil is not magnetizing.
Solenoid cartridge valve may be
contaminated or damaged. A bent or
over torqued cartridge will not allow the
valve to move freely inside of the
cartridge.
Skid steer hydraulic fluid flow is set to
variable flow.
Diodes may be corroded or damaged.
Wire harness may be damaged.
Hydraulic hoses are connected wrong
or coils and wiring are incorrect.
Pressure (P) and tank (T) hoses are
installed in the wrong position on the
skid steer.
Skid steer computer conflicts with
cylindrical connection.
The wing pressure relief valve is
contaminated.
The angle pressure relief valve is set
too low. NOTE: Increasing the pressure
relief valve will cause damage to your
plow. Do not set the pressure relief
greater than 3000PSI.
Control station, harness or cables may
be loose or improperly connected.
No power to the cartridge valve.
Coils are receiving power.
Solenoid cartridge may be
contaminated or damaged. A bent
cartridge will not allow the valve to
move freely inside of the cartridge.
Review all probable causes above.
SOLUTION
S5 coil should magnetize with each
function.
Determine a damaged cartridge valve
by reversing the driver's side and
passenger's side cartridge valves one at
a time. Replace valve if necessary.
For plow functions to work, the skid
steer hydraulic fluid flow should be set
to continuous flow. Review your skid
steer operation manual for proper flow
settings.
Clean diodes thoroughly and/or replace.
Verify harness is not damaged. Review
schematic(s) to troubleshoot
connection(s). Replace if needed.
Review the Hydraulic Valve &Hose Port
Identification Guide under the A-frame
cover for proper port locations and/or
place respective coils over correct
valves.
Review the skid steer operation manual
to determine the pressure and tank
connections.
Using a jumper wire, connect pin K to
pin L at the back of the cylindrical
connector (cylindrical connector only).
Test the wing pressure relief. Attach a
T-fitting with a fluid PSI gauge to the
base end of the wing cylinder. Pressure
relief should not be greater than
1700PSI (2800PSI for 8611SS) Replace
if less than 1500-1700PSI (2600-
2800PSI).
Follow the guidelines indicated above;
however, the PSI setting should not
exceed 3000PSI. NOTE: If the plow is
floating back when angled to the right,
adjust the left pressure relief valve and
vice versa.
Verify control station, harness and all
cables are securely connected. Clean if
necessary.
Verify S9 &S10 coils (passenger's side
slide box retract and extend) and S1
&S2 (driver's side slide box retract and
extend) are connected properly.
Diagnose the wire harness. Review all
wire harness schematics. If power is
present, review the next step.
Verify coils are magnetizing. Position a
screwdriver inside of the coil. When the
respective function is activated, the
screwdriver is drawn to the side of the
coil. If the coil is not drawn to the
screwdriver, replace the coil. If power is
present, review the next step.
Determine a damaged cartridge valve
by reversing the driver's side and
passenger's side cartridge valves.
Replace valve if necessary.
NOTE: Verify coils S3 & S4 for angle
functions.
