Service Override Mode
The Electronic Control Module (ECM) is
programmed with a Service Override mode.
Service Override mode is only indented for certain
circumstances and is not part of the normal
machine operation. Service Override mode should
only be accessed by trained personal to repair
faults and/ or a malfunctioning machine.
Note: Service Override mode can only be entered
at the ground controls and is intended to allow the
platform to be raised or lowered. Once the platform
has reached the maximum allowable height, the
system will exit Service Override mode. Repeat this
procedure to lower the platform.
Note: When in Service Override mode, an audible
alarm will sound.
Note: Before entering Service Override mode, fault
codes or the malfunction affecting the operation of
the machine should be fully understood to ensure
Service Override mode is required.
Note: Perform this operation on a firm, level
surface and if equipped, with the outriggers auto
leveled or fully retracted.
Tip-over hazard. Operating the
machine on a surface that is not
level while in Service Override
mode will result in death or
serious injury. Follow proper
operating procedures and safety
precautions. Do not use Service
Override mode if you are not
trained and familiar with the
operation of the machine.
