8. Unscrew the cap from the test point and attach a pressure gauge - capable of
reading pressure up to 300 bar (4400 PSI).
9. Exit the area between the left-hand and right-hand platforms behind the mast.
Ensure all surfaces are clean and dry and take great care to avoid slipping!
10. 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.
11. Press the accelerator pedal down fully 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).
12. The reading on the pressure gauge indicates the pressure setting on one
particular port on the valve chest.
Example: To check the lift pressure, raise the mast to full height. Press the
accelerator pedal down fully and pull the lift lever back. The pressure gauge will
display the setting on the lift port.
Example: To check the mast reach extend pressure, raise the forks off the ground
then extend the mast reach out as far as it will go. Fully depress the accelerator
pedal and push the reach lever forward. The pressure gauge will display the setting
on the reach extend port.
The valve chest pressure readings should be in line with those given in the following
tables.
