Operator Presence Footswitch
An integral part of the Platform Control system is the

Presence Footswitch to allow operation of the Platform
Controls.
NOTE: In order to activate the Platform Controls the red
Emergency Stop button must be pulled to activate
the radio remote transmitter.
If a platform function is not activated within 10 seconds, the
platform controls are deactivated. The operator must step off
the operator presence footswitch, then depress it again to
activate the platform controls. (Reference Figure 5-8).
Operator Feedback Screen
The LCD screen on the platform controls aides in operation
by displaying important information that can be toggled to
monitor the current configuration of the controls and the
operating state of the aerial lift. Figure 5-9 shows a sample
screen with the various icons that can be displayed in real
time on the screen and how to interpret this information.
DANGER
To avoid serious injury Do Not remove modify or disable
the operator presence footswitch by blocking or any other
means. Always keep work platform floor clean and free of
debris which may interfere with operator presence
Footswitch operation.
