The charge pressure should measure between 20 - 28 bar (290 – 406 PSI).
5.4: Valve Chest Pressure Settings
In order to check the valve chest pressure settings, the following steps should
be taken:
Attach a pressure gauge to the test
point on the valve chest as illustrated
opposite.
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 push/pull the lever on the section
to be tested (in the example of testing
the tilt back pressure the lever will be
pulled 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 push the tilt lever forward. The pressure gauge
will display the setting on the tilt forward port.
Port "G"
Warning
Ensure that the Machine is switched off until the pressure gauge has been
attached and the hose bunged before trying to read the charge pressure.
