MANUAL BOOM OPERATION
Manual retraction, rotation and lowering functions
allow the aerial work platform to be moved and
lowered during hydraulic power interruption or
failure. In each instance, refer to Figure 3-7.
The following procedures for manual retraction,
rotation and lowering require a person on the ground
to operate the manual controls and hand pump.
The hydraulic hand pump is located in the pump
compartment. In case of a power failure, the hand
pump and selected hydraulic valve settings can be
used to manually retract the Telescoping boom or
rotate the boom turntable.
To begin manual retraction or rotation, turn
Proportional Valve counterclockwise until it stops,
and insert pump handle into the pump handle fitting.
