Service Bypass/Recovery
Key Switch
The ground control box contains two key switches.
The main key switch towards the top of the control
box is for selection of ground or platform controls.
The key switch at the bottom of the control box is
the Service Bypass/Recovery key switch. Service
Bypass and Recovery modes are only intended for
certain circumstances and are not part of normal
machine operation. If either the Service Bypass or
the Recovery function is required, this indicates
there may be faults with the machine. Contact
trained personnel immediately.
Service Bypass is used for a platform out-of-
envelope condition and certain service situations.
Recovery is only to be used as a last attempt to
lower the platform when the operator in the
platform is unable to do so, system failure or in
emergency situations.

How to Use the Service Bypass
Mode
Tip-over hazard. Operating the
machine outside of the operating
envelope while in Service Bypass
mode will result in death or serious
injury if proper operating
procedures and safety precautions
are not followed. Do not use this
mode if you are not trained and
familiar with the operating
envelope of the machine.
Note: Before using the Service Bypass mode,
make sure you understand the fault code or issue
affecting the operation of the machine to be sure
the use of service bypass is required.
The Service Bypass mode will allow the platform to
be manually leveled when an out-of-envelope
condition exists. In the event that the platform
angle is greater than 10° from level, the boom
angle and platform level functions are disabled.
Use of the Service Bypass mode will allow the
platform to be manually adjusted to within the
normal operating envelope, ±4.5°. Only auxiliary
power can be used to correct an out of level
platform fault.
