How to Test the Function Pump
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications,
Hydraulic Hose and Fitting Torque
Specifications.
1 Tag, disconnect and plug the high pressure
hydraulic hose from the function pump.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
2 Connect a 0 to 5000 psi / 0 to 350 bar
pressure gauge to the high pressure port on
the pump.
3 Turn the key switch to ground control and pull
out the red Emergency Stop button to the on
position at both the ground and platform
controls.
4 Hold the function enable switch to either side
and activate any boom function from the
ground controls.
Result: The pressure gauge reads 3000 psi /
206 bar, immediately stop. The pump is good.
Result: The pressure fails to reach 3000 psi /
206 bar, the pump is faulty and will need to be
serviced or replaced.
Component damage hazard.
Hydraulic pressure in excess of
3000 psi / 206 bar may result in
severe component damage.
5 Remove the pressure gauge and install the
hydraulic hose.
