Platform Overload System
How to Calibrate the Platform
Overload System
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.
