Platform Overload System (if
equipped)
The platform overload system is designed to
prevent the machine from continuing to operate
when the load in the platform exceeds maximum
rated capacity. Refer to the machine serial label for
maximum capacity information.
If maximum platform capacity is exceeded, the
alarm will sound and the platform overload indicator
lights will flash at the platform control and
"PLATFORM OVERLOAD" will display on the LCD
screen at the ground control. The ground and
platform controls will become disabled. Before
normal machine operation can continue, the excess
load will need to be removed from the platform.
If the excess load cannot be removed or if the
operator at the platform controls is unable to correct
the overloaded condition, another person at the
ground controls can operate the machine using
auxiliary power. There will be limited control of
boom functions from the ground controls when
using auxiliary power. Auxiliary power can be used
to correct the overloaded platform condition in order
to resume normal, safe operation of the machine.
Note: The engine must be turned off to use auxiliary
power.
Note: Software versions 1.03 and lower. All
ground control functions will not operate with
auxiliary control. Refer to Repair Procedure, How to
Determine the Revision Level.
Note: Recovery mode must be used. Refer to
Repair Procedure, Bypass / Recovery Keyswitch.
Note: Software versions 1.04 and higher. All
ground control functions will operate from auxiliary
control. Refer to Repair Procedure, How to
Determine the Revision Level.

How to Calibrate the Platform
Overload System (if equipped)
Proper calibration of the platform overload system
is essential to safe machine operation. Continued
use of an improperly calibrated platform overload
system could result in the system failing to sense an
overloaded platform. The stability of the machine is
compromised and it could tip over.
Note: Perform this procedure with the machine on a
firm, level surface.
1 Turn the key switch to platform control. Start
the engine and level the platform.
2 Determine the maximum platform capacity.
Refer to the machine serial plate.
3 Remove all weight, tools and accessories from
the platform.
Note: Failure to remove all weight, tools and
accessories from the platform will result in an
incorrect calibration.
4 Using a suitable lifting device, place a test
weight equal to the maximum platform
capacity at the center of the platform floor.
