Main Function Pump
How to Test the Main Function
Pump
1 Disconnect and plug the high pressure
hydraulic hose from the main 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 lift up
the Emergency Stop Switch cover at the
ground controls and move the switch to the
ON
position.
4 Activate the function enable switch any lift
function from the ground controls.
Result: If the pressure gauge reads 2000 psi
(137.9 bar), immediately stop. The pump is
good.
Result: If pressure fails to reach 2000 psi
(137.9 bar), the internal relief valve setting is
incorrect or the pump is bad and will need to be
serviced or replaced.
5 Remove the pressure gauge and reconnect the
hydraulic hose.
How to Remove the Main
Function Pump
