6.4: Hydraulic Functions Pressure Settings
In order to check the hydraulic functions pressure settings, the following steps
should be taken:
Ensure the engine is switched off and the park brake applied.
Attach a pressure gauge to the gauge port on the steering and
hydraulic functions pump as indicated in the diagram below.
Start the engine.
Using the joystick in the cab fully extend or retract the cylinder(s) of the
function to be tested. For example when checking the tilt-back pressure
the mast must be tilted back as far as it will go.
Fully depress the accelerator pedal and use the joystick to operate the
function being tested (in the example of testing the tilt back pressure
scroll the tilt scroll wheel back).
The reading on the gauge indicates the pressure setting on one
particular port on the valve chest.
Example: To check the tilt forward pressure tilt the mast forward as far
as it will go. Fully depress the accelerator pedal and scroll the tilt scroll
wheel forward. The pressure gauge will display the setting on the tilt
forward port.
