Step 1:
1. Lubricate all threads and O-Rings with hydraulic fluid before installing fittings
into manifold valve. All ports are ¾-16 SAE straight thread. Do not use
Teflon tape or pipe dope.
2. Install Female ISO quick couplers in ports 1A, 1B, 2A and 2B.
3. Install Male ISO tips to eccentric fittings
4. Install Male tip/eccentric fitting has a unit onto the manifold body ports P1
and P2 with the jam nut towards the valve. Do not tighten until you adjust
the spacing to fit your tractors SVC port
Step 2:
Install manifold valve assembly into your tractor’s
remote outlet:
1. Adjust male tips and insert into the remote outlet
2. Push valve firmly into place using the SCV release
lever where necessary.
3. Tighten jam nuts to 35 ft-lbs once valve is seated
in SCV
Connects to ISO Male Tip
This end connects to manifold
ports P1 and P2
Install directly to Tractor’s SCV or
Remote outlet

Step 3:
Mount Control Switch to or near the SCV lever that controls the SCV valve
the manifold is plugged into.
1. Route grey cable with the 2 connectors
to the manifold
2. Connect the Green and Black wired
connector to the Circuit 1 solenoid,
Labeled SV1
3. Connect the Red and White wired
connector to Circuit 2 solenoid, Labeled
SV2
4. Attach the red power wire to a keyed
power source that is “hot” only when the
engine is running, such as an accessory
terminal.
5. Attach the black wire to a clean metallic
surface, for a metal to metal ground.
Operation (Switch Box Control):
The switchbox contains two switches, the large lighted Rocker switch at the top of
the box selects circuit 1 or circuit 2. Press the switch to the left to operate circuit 1
or to the right to operate circuit 2. Once the circuit is selected, the tractor remote
lever directs flow of oil.
The Red Push Button toggle switch on the side of the switchbox allows you to
“combine” 1 and 2, so you can operate both circuits simultaneously. The valve is
designed be run continuously or intermittently.

Notes:
WARNING: DO NOT LOOSEN OR REMOVE ANY FITTINGS, COUPLERS OR VALVE
CARTRIDGES WHILE THE SYSTEM IS UNDER PRESSURE OR WHILE A LOAD IS
BEING HELD UP BY THE VALVE.
Pressure and return are determined by the position of the tractor lever
Must be used with the tractor remote outlet. Valve does not control, but selects
circuit.
Troubleshooting:
The valve will
not work
 Low or no
voltage between
the coil terminal
and top coil nut
 Not properly
grounded
 Use a voltmeter to check between the coil
terminal and the outlet. There should be at
least 11 volts
 Check coils for magnification. To check, place
a small metal object on top of the coil nut.
 Check ground connection. Ensure there is
metal to metal contact for a secure ground.
Valve was
previously
working
 Blown Fuse
 Damaged Wire
 Bad Switch
 Check hydraulic connections to see if it was
installed correctly. See installation guide for
proper instructions.

Inspect tips and couplers for proper mating
Only one of
the two
circuits is
working
 Coil may be bad
 Cartridge may
be
contaminated
 Exchange wires between the working coil and
the non-working circuits
 If problem persists exchange coils from circuit
one to circuit two
 If problem changes to opposite circuit, the coil
may be bad and need to be replaced.
 If the problem remains on the same circuit,
exchange the cartridge from circuit one to
circuit two. If the problem changes to the
opposite circuit, the cartridge may be some
contamination.
 Visually inspect the cartridge, if no
contamination is found the cartridge could be
bad and need to be replaced.
