Platform Overload System (if
equipped)
How to Calibrate the Platform
Overload System
Perform this procedure with the machine in the
stowed position and on a firm, level surface that is
free of obstructions.
Personnel are not allowed in the platform while
calibrating the platform overload system.
Perform this procedure in an environment that
allows the platform to be fully raised. Models rated
for indoor use only, should be calibrated inside a
facility with enough ceiling height to fully raise the
platform. If the facility height is not suitable to fully
raise the platform, then an indoor only rated model
may be calibrated outdoors if wind speeds are less
then 28 mph / 12.5 m/s. Only use flat weights
while calibrating indoor only rated machines,
outdoors.
Perform this procedure after confirming that the
platform height sensor is not damaged and
functions correctly.
There are two options to the platform overload
calibration procedure in this section, Full Load
Calibration and No Load Calibration. Full Load
Calibration has two steps requiring calibration with
and without rated load in the platform. No Load
Calibration does not require rated load in the
platform.
Note: No Load Calibration can be completed stand
alone to fulfill the C-2 overload calibration
requirements, if the machine has completed the
Full Load Calibration procedure.
Note: If a new Ground Controller is installed on a
machine, the Full Load Calibration procedure is
required to maintain rated load platform capacity.
If a No Load Calibration is performed, machine
lifting performance will be significantly reduced.
Note: Ambient temperature must be above 32°F /
0°C before calibrating the Platform Overload
System.
Note: To calibrate the platform overload system,
follow the menu structure indicated on the ground
control LCD display.
