Upper controls
The one-hand joystick control mounted on the side of the platform operates the aerial
device movement.
The functions operated are:

Upper boom “EXTEND/RETRACT”

Rotation “CLOCKWISE/COUNTERCLOCKWISE”

Lower boom “UP/DOWN”
In addition to providing for directional control of the aerial
device, the single handle controller has an interlock button
(trigger) fitted into the handle. The joystick trigger must be
depressed before any movement of the joystick handle.
The main control valve at the pedestal on the standard unit is adjusted to provide optimal
operation of the three (3) boom functions. Since, the standard "ON/OFF" joystick provides
"ON/OFF" displacement of the boom functions, then if the pump flow available is lower
than the demand, the boom speeds will be reduced according to the number of functions
activated simultaneously. Moreover, the flow will divert to the maximum flow of the less
demanding (easiest to operate) function first. If there is still some flow available, then the
next less demanding function will use the remaining flow.
Caution
The interlock button must be fully depressed before the controller handle is moved
in any direction. Releasing the interlock button before centering the control handle
may produce sudden and abrupt stopping of movement.
Testing the Interlock System
It is recommended that the interlock system be tested daily to assure that it is operating
properly. Testing can be easily accomplished by simply moving the single handle
controller without depressing the interlock button (trigger). If movement of the booms or
rotation occurs, the cause should be determined and the unit not operated until the
problem is corrected.
Caution
When testing the operation of the interlock system, the platform and booms should be
in such a position that no damage can result from unexpected unit movement.
