How to Use the Bypass Mode
Tip-over hazard. Operating the
machine outside of the operating
envelope while in 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 Bypass mode, make sure
you understand the fault code or issue affecting the
operation of the machine to be sure the use of
bypass is required.
The Bypass mode will allow the platform to be
manually leveled when an out-of-level 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 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.

3 Turn the bypass/recovery key switch to the
bypass position.
4 Using auxiliary power, operate the ground
control buttons to level the platform.
