Hydraulic Pressure Settings
The hydraulic system has three pressure settings which have to be set as follows:
(2)
MAIN SYSTEM RELIEF
PRESSURE TEST POINT
(1)
OVERCENTRE VALVE
(3)
LIFT PRESSURE
Before any testing is carried out run the engine and hydraulic system to warm the hydraulic oil to 80°C ( 176°F ).
All pressure setting are performed with the engine running at full speed (3600 rpm).
OVER CENTRE VALVE
Connect an accurate pressure gauge with a range 0-300 bar ( 0-4300 PSI ) to the test point.
The pressure should be set at: 32 bar (460 PSI) for Series 5 machine
41 bar (600 PSI) for Series 6 machine
NOTE: If adjustment is required slacken off the lock nut and using a 5mm hex key wind in the screw to
increase the pressure or back off the screw to reduce the pressure. Retighten the lock nut when
adjustments are complete.
(2) MAIN SYSTEM RELIEF PRESSURE
Connect an accurate pressure gauge with a range 0-300 bar ( 0-4300 PSI ) to the test point.
Check the pressure while pulling the tilt control lever at the end of the rams stroke.
The pressure should be set at 203 bar (2950 PSI) .
NOTE: If adjustment is necessary slacken off the lock nut and wind in the screw to increase the pressure
or back off the screw to reduce the pressure. Retighten the lock nut when adjustments are complete.
LIFT PRESSURE
Connect an accurate pressure gauge with a range 0-300 bar ( 0-4300 PSI ) to the test point.
Check the pressure while pulling the boom control lever at the end of the rams stroke (boom fully
risen).
The pressure should be set at 165 bar (2400 PSI).
NOTE: If adjustment is necessary unscrew and remove the cap lock nut and wind in the screw using a
screw driver to increase the pressure or back off the screw to reduce the pressure. Refit
and tighten
the lock nut when adjustments are complete.
