not fully lower to the ground when
the recovery mode is completed.
Failure to use only suitable
equipment and/or practices to
allow the operator to safely exit
the platform could result in death
or serious injury.

The Recovery mode allows the platform to be
lowered in the event the operator in the platform is
unable to lower the platform using the platform
controls, system failure or emergency situations.
The recovery sequence will automatically retract
the primary boom and then lower the primary boom

at the platform controls to exit the platform.

Remove the key from the main key switch and
insert the key into the service bypass/recovery
key switch.
2 Turn and hold the service bypass/recovery key
switch to the recovery position. The switch must
be held in the recovery position.
Result: The auxiliary power unit will turn on and
the boom will begin the following recovery
sequence.
· The primary boom will retract
· The primary boom will lower
Note: The key switch must be held in the recovery
position until the recovery sequence is complete or
until the operator in the platform can safely exit the
platform.
Note: If any boom safety limit switches are faulty,
the boom will only retract and not lower and the
operator will need to be recovered from that point.
Note: If the Recovery function has been used, this
may indicate there may be faults with the machine.
Tag and remove the machine from service until the
