DO NOT PLACE LOADS IN THE PLATFORM TO CAUSE AN OVER-
LOAD. IF AN OVERLOAD CONDITION IS REACHED, IMMEDIATELY
STOP OPERATION, REMOVE EXCESS LOAD, AND RETRACT THE
UPPER BOOM AND LOWER THE PLATFORM TO THE GROUND.
NO FUNCTIO NS ARE CUT OUT BY THIS SYSTEM. IF THE
MACHINE IS OVERLOADED, HAVE THE MACHINE INSPECTED BY
A QUALIFIED PERSON BEFORE RESUMING OPERATION. FAIL-

The Load Sensing System consists of load cells mounted
beneath the platform and a display unit mounted on the
platform next to the control console. The system acts as a
load sensing device which sounds a warning when an
overload condition is being reached or when an overload
condition is occurring. The Load Sensing System only
operates when the platform control console is powered.
