Test the Platform Overload
System (if equipped)
Note: Genie specifications require that this
procedure be performed every 500 hours or six
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.
Note: Perform this procedure with the machine on a
firm, level surface.
1 Turn the key switch to platform control.
2 Level the platform from the platform controls.
3 Determine the maximum platform capacity.
Refer to the machine serial plate.
4 Using a suitable lifting device, place an
appropriate test weight equal to that of the
maximum platform capacity in one of the
locations shown.
Result: The platform overload indicator light
should be off at both the ground and platform
controls.
5 Carefully move the test weight to each
remaining location.
Result: The platform overload indicator light
should be off at both the ground and platform
controls.
6 Add an additional 10 lbs / 4.5 kg of weight to
overload the platform.
Result: The alarm should be sounding.
The platform overload indicator light should be
flashing at both the ground and platform
controls.
Result: If the alarm does not sound and the
platform overload indicator light does not come
on with the test weights in any of the platform
locations, the platform overload system needs
to be calibrated. See D-5,
Calibrate the
Platform Overload System .
Note: There may be an approximate 2 second delay
before the overload indicator light turns on and the
alarm sounds.
