Function Pump
The hydraulic pump is attached to the motor which
makes up the hydraulic power unit.
How to Test the Hydraulic Pump
When removing a hose assembly or fitting, the
fitting and/or hose end must be torqued to
specification during installation.
Refer to Section 2,
Hydraulic Hose and Fitting
Torque Specifications.
1 Tag, disconnect and plug the high pressure
hydraulic hose from the hydraulic 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 Activate the platform up function from the
ground controls.
Result: If the pressure gauge reads
3200 psi / 221 bar, immediately stop. The pump
is good.
Result: If pressure fails to reach
3200 psi / 221 bar, the pump is bad and will
need to be serviced or replaced.
Component damage hazard.
There is no relief valve in the
hydraulic pump and the pump can
be damaged if the pressure is
allowed to exceed
3200 psi / 221 bar. When testing
the pump, activate the pump in
one second intervals until
3200 psi / 221 bar is confirmed.
Do not over-pressurize the pump.
5 Remove the pressure gauge and reconnect the
hydraulic hose. Torque to specification.
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.
