JOYSTICK CONTROL AND PARK BRAKE
PRESSURE TEST
STEP 86
If the forklift does not respond to the joystick
controller and the problem is not the pump or
cylinders, proceed to Step 93.
If the forklift does not respond to one of the joystick
controller commands, proceed to the next step.
If the park brake does not respond to the park brake
switch, proceed to Steps 94 and 95.
STEP 87
G0805131
Remove the supply hose from the hydraulic solenoid
(1) of the function to be tested. Install a 1000 psi (69
bar) pressure gauge and hose (2) between the
hydraulic solenoid (3) and the supply hose.
NOTE:
The hose must be long enough to observe
the pressure gauge from inside the cab or standing
clear of the forklift.
STEP 88
G0805077
Start the engine and run at 1000 RPM. The park
brake must be ON. Hold the joystick in the position of
the solenoid to be tested. (The example shown is
Boom RETRACT). The pressure gauge should read
350 psi (24 bar).
If the pressure is 350 psi (24 bar) but there is no
response to the joystick command, repair or replace
the control solenoid or the control valve section.
If the pressure is less than 350 psi (24 bar), proceed
to Step 95.
If the pressure is more than 350 psi (24 bar), proceed
to the next step.
STEP 89
Shut off the engine. Replace the flow divider. Repeat
Step 88.
STEP 90
G0805186
Shut off the engine. Remove the pressure gauge tee
adapter (1) from the solenoid port adapter (2). Install
a cap in the port adapter (2) and a plug (3) in the
gauge tee adapter (1).
