WARNING: Before removing hydraulic
lines or components, relieve pressure in
the hydraulic system. With the truck off,
open the truck auxiliary control valves
several times in both directions.
There are six potential problems that could affect the fork
positioning function:
• Bent arm bars.
• Incorrect hydraulic pressure or flow from lift truck.
• Defective gas cylinders.
• External leaks.
• Defective solenoid coil or valve (if equipped).
• Worn/defective cartridge valves or cylinder seals.
4.3-1 Fork Position Circuit Test
1 Check the truck pressure at the carriage hose
terminal. Pressure must be within 100 psi (7 bar) of
the specifications in the truck service manual. TRUCK
PRESSURE MUST NOT EXCEED 2600 psi (180 bar).
See Section 6.1 for recommended operating pressure.
2 Check the flow volume at the carriage hose terminal.
See Section 6.1 for recommended flow volume.
3 Spread the forks and check that the inner forks remain
in contact with the outer forks until reaching their stops.
If they do not, the gas cylinders or spring cylinders are
faulty. Replace the gas cylinders (see Section 5.7-2 or
3) or spring cylinders (see Section 5.7-5).
4 Spread the forks fully and hold the lever in the OPEN
position for 2 seconds. Release the lever and check for
external leaks at fittings, hoses, valve and manifold.
5 Press the solenoid button (if equipped) and listen for a
‘click’ at the solenoid valve. If no sound is heard, check
the fuse, wiring and coil (see Section 4.5).
IMPORTANT: Solenoid-operated valves must be
plumbed so that the solenoid is energized during the
fork positioning function.
6 Open and close the forks fully. If the arms move at
different speeds, the flow divider/combiner cartridge
may be faulty. Replace the cartridge.
7 Turn the truck off and connect a 3500 psi (240 bar)
pressure gauge to the TEST port on the main valve.
8 Start the truck and close the forks fully. Hold the lever in
the CLOSE position for a few seconds.
9 Release the lever and watch the pressure gauge:
• If the pressure drop is less than 150 psi (10 bar)
initially, and additional drop does not exceed 25 psi
(2 bar) per minute, the problem is not hydraulic (see
Section 4.1-3).
• If the pressure drop is more than above, the check
valve cartridge may be faulty. Replace the
cartridge.
10 Close the forks fully and hold the lever in the CLOSE
position for a few seconds. If the pressure still drops as
before, the cylinders are at fault and must be serviced

valves several times in both directions.
4.4 Sideshift Function
There are five potential problems that could affect the
sideshifting function:
• Inadequate sideshifter upper bearing lubrication or
worn bearings (see Section 5.7-1).
• Incorrect hydraulic pressure or flow from lift truck.
• External leaks.
• Lower mounting hooks installed incorrectly (see
Section 5.1 Step 6).
• Worn or defective cylinder seals.
4.4-1 Sideshift Circuit Test
1 Check the truck pressure at the carriage hose terminal.
Pressure must be within 100 psi (7 bar) of that specified
in the truck service manual. TRUCK PRESSURE
MUST NOT EXCEED 2600 psi (180 bar). See Section
6.1 for recommended operating pressure.
2 Check the flow volume at the carriage hose terminal.
See Section 6.1 for recommended flow volume.
3 Sideshift left or right fully, holding the lever in the
SIDESHIFT position for a few seconds. Release the
lever and check for external leaks at fittings, hoses,
valve and manifold.
4 Press the solenoid button (if equipped) and listen for a
‘click’ at the solenoid valve. If no sound is heard, check
the fuse, wiring and coil (see Section 4.5).
IMPORTANT: Solenoid-operated valves must be
plumbed so that the solenoid is energized during the
fork positioning (not sideshifting) function.
5 Turn the truck off and relieve system pressure.
Disconnect the SIDESHIFT RIGHT supply hose from
the sideshift cylinder. Plug the hose end. Install a drain
hose from the cylinder fitting to a catch bucket.
6 Start the truck. Actuate the SIDESHIFT LEFT lever for 5
seconds.
• If there is substantial hydraulic flow out of the drain
hose, the sideshift cylinder is faulty and requires
service (see Section 5.3).
• If there is no hydraulic flow out of the hose, the
problem is not hydraulic (see Section 4.1-3).

4.5 Electrical Circuit
(Solenoid-equipped attachments)
Use the schematic shown and follow the steps below.
1 Check the control knob circuit fuse. Replace if
necessary.
2 Check for loose electrical connections at the truck
ignition switch, control knob button, solenoid coil
terminals and diode.
3 Remove the diode from the solenoid coil terminal. Test
with an ohmmeter for high resistance in one direction
and no resistance in the other direction. If there is no
resistance in both directions, replace the diode.
NOTE: When replacing the diode, the banded end
must be connected to the coil and wiring as shown.
4 Disconnect the electrical leads from the solenoid coil
terminals. Use a voltmeter to take a current reading
at the electrical lead terminals when the button is
depressed.
• If there is no current to the solenoid, troubleshoot
the electrical circuit for shorts.
• If there is current to the solenoid, test for coil
continuity.
5 Test for coil continuity by placing an ohmmeter test lead
on each solenoid coil terminal (ohmmeter on Rx1 scale).
• If there is an ohmmeter reading, the coil is good.
• If the coil is good, but the solenoid does not ‘click’
when the control button is depressed, the solenoid
cartridge may be jammed.
• If there is no ohmmeter reading, the coil is defective
and should be replaced.
