Test the Platform Overload
System (if equipped)
Genie specifications require that this procedure
be performed every 500 hours or six months,
whichever comes first 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.
1 Disconnect the platform controls from the
machine at the platform.
2 Open the side covers at the ground controls side
of the machine.
3 Locate the Electronic Control Module (ECM) wire
harness 6 pin connector to platform controls
connection below and behind the control box.
4 Securely connect the platform controls to the
ECM wire harness.
5 Tag and disconnect the platform controls wire
harness from the ECM wire harness.
6 Securely connect the platform controls to the
ECM wire harness..
