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 Turn the key switch to platform control and pull
out the red Emergency Stop button to the on
position at both the ground and platform
controls.
2 Determine the maximum platform capacity.
Refer to the machine serial plate.
3 Using a suitable lifting device, place an
appropriate test weight equal to the maximum
platform capacity in the center of the platform
floor.
Result: The diagnostic display at the ground
controls will show two flat bars and a blinking
light, indicating a normal condition, and the
diagnostic display at the platform controls will
show the battery condition. Refer to Repair
procedure 1-3, How to Determine the Battery
Voltage.
Result: The diagnostic display will show 'OL' at
both the ground and platform controls. The
platform overload system is not operating
properly. See D-1, Calibrate the Platform
Overload System (if equipped).
4 Add an additional weight to the platform not to
exceed 20% of the maximum rated load. Refer
to the machine serial plate.
Result: The diagnostic display will show 'OL' at
both the ground and platform controls. The
platform overload system is operating properly.
Result: The diagnostic display at the ground
controls will show two flat bars and a blinking
light and the diagnostic display at the platform
controls will show the battery condition. The
platform overload system is not operating
properly. See D-1, Calibrate the Platform
Overload System (if equipped).
5 Test all machine functions from the platform
controls.
Result: All platform control functions should not
operate.
