Test the Platform Overload
System - ALC1000 Models
Genie specifications require that this procedure be
performed annually OR when the machine fails to
lift the maximum rated load.
Testing the platform overload system regularly is
essential to safe machine operation. Continued
use of an improperly operating platform overload
system could result in the system not sensing an
overloaded platform condition. Machine stability
could be compromised resulting in the machine
tipping over.
This maintenance procedure applies to the
following models:
S-100, S-105, S-120, S-125, S-
100HD, S-120HD, SX-150 (to SX150H-611), SX-
180 (to SX180H-744), Z-80/60, Z-135/70 and ZX-
135/70 (to ZX135H-4000).
Note: Perform this procedure with the boom fully
retracted and in the stowed position and with the
machine on a firm, level surface.
1 Remove all weight, tools, accessories and
equipment from the platform.
Note: Failure to remove all weight, tools and
accessories from the platform will result in an
inaccurate test.
2 Turn the key switch to ground control and pull
out the red Emergency Stop button to the on
position at both the ground and platform
controls. Start the engine from the ground
controls and level the platform. Do not turn
the engine off.
3 Determine the maximum platform capacity.
Refer to the machine serial plate.
