Test the Recovery System - ALC-
1000 Models
Genie specifications require that this procedure be
performed quarterly.
A properly functioning recovery system is essential
to safe machine operation. 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.
This maintenance procedure applies to the
following models:
S-100, S-105, S-120, S-125, S-
100HD, S-120HD, SX-105XC, SX-125XC, SX-
135XC, SX-150, SX-180, Z-80/60, Z-135/70 and
ZX-135/70.
Note: Perform this procedure with the machine on
a firm, level surface with the axles extended.
Note: Perform this procedure with all weight, tools,
equipment and personnel removed from the
platform.
Note: If any boom safety limit switches are
faulty, the primary boom will only retract and
not lower.
