Checklist C Procedures; Calibrate The Platform Overload System (If Equipped) - Genie GR-20J Service Manual

Section 3 • Scheduled Maintenance Procedures
Checklist C Procedure
C-1
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
overload pressure sensors.
3 - 24
Models equipped with the platform overload option
are provided with additional machine components:
an adjustable spring-loaded subassembly, a limit
switch harness, an electronic module which
receives the overload signal and interrupts power,
and an audio/visual warning indication to alert the
operator of the overload.
Refer to Repair Procedure 2-2, How to Calibrate
the Platform Overload System (if equipped).
