Tag, disconnect and plug the high pressure
hydraulic hose from the auxiliary 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.

Connect a 0 to 5000 psi / 0 to 350 bar
pressure gauge to the high pressure port on
the pump.

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.

Result: The pressure fails to reach 2800 psi
/193 bar, the pump is faulty and will need to be
serviced or replaced.
