Calibrate 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.
Calibrating 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.
The platform overload system is designed to
prevent machine operation in the event the
platform is overloaded. Models equipped with the
platform overload option are provided with two
additional machine control components: the
overload pressure transducer and the platform
height sensor.
The overload pressure transducer, located at the
barrel-end of the lift cylinder, is used to determine
the pressure inside the lift cylinder.
The platform height sensor, located at the steer
end of the chassis, battery side, is used to
determine the height of the platform.
The overload pressure transducer and the platform
height sensor provide the ECM with necessary
information to determine the load in the platform.
Note: The overload system will not measure loads
at, or below the height of the Down Limit Switch.
Refer to Repair Procedure 9-10, How to Calibrate
the Platform Overload System (if equipped).
