The function pump is a pressure compensated,

Genie Product Support to locate your local
authorized service center.
How to Remove 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
Locate the two hydraulic tank valves at the
hydraulic tank. Close the valves.
Component damage hazard.
The engine must not be started
with the hydraulic tank shut-off
valves in the closed position or
component damage will occur. If
the tank valves are closed,
remove the key from the key
switch and tag the machine to
inform personnel of the
condition.
2
Tag, disconnect and plug the function pump
hydraulic hoses. Cap the fittings on the 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.
3
Support the pump with a suitable lifting device.
4
Remove the two pump mounting fasteners.
Carefully remove the pump.
Component damage hazard. Be
sure to open the two hydraulic
tank valves and prime the pump
after installing the pump.
