Checklist C Procedures

C-1
Grease the Platform Overload
Mechanism (if equipped)
Genie specifications require
that this procedure be performed
every 500 hours or 6 months,
whichever comes first. Perform
this procedure more often if dusty
conditions exist.
Application of lubrication to the platform overload
mechanism is essential to safe machine operation.
Continued use of an improperly greased platform
overload mechanism could result in the system not
sensing an overloaded platform condition and will
result in component damage.
1 Locate the grease fittings on each pivot pin of
the platform overload assembly.
2 Thoroughly pump grease into each grease
fitting.

C-2
Test the Platform Overload
System (if equipped)
Genie specifications require that
this procedure be performed every
500 hours or 6 months, whichever
comes first.
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.
Perform this procedure with the
machine on a firm, level surface.
1 At the ground controls, extend the outriggers
until the axle is off the ground and the machine
is level.
2 Release the boom hold down latch.
3 Turn the key switch to platform control.
4 Level the platform.
5 Determine the maximum platform capacity.
Refer to the machine serial plate.
6 Using a suitable lifting device, place an
appropriate test weight equal to that of the
maximum platform capacity in the center of the
platform floor.
Result: The platform overload indicator light
should be off at both the ground and platform
controls.
