NOTE: One of the capacity indicator lights should be illumi-
nated at all times during operation. If no capacity
lights are on, a bulb could be burned out. Operation
of the machine must be halted until the lights are
working properly.
Check the capacity decal in the platform and at the
ground control station for the machines operating
capacity(s).
27. Capacity Indicator and Exceeding Operating Radius
Indicator
The capacity indicator and exceeding operating
radius indicators display to the operator the maxi-
mum rated platform capacity and the maximum
radius for that capacity using different colored lights.
The operator must not exceed the rated capacity or
the maximum radius for the load (personnel, tools,
and supplies) shown on the indicator.
A light for each different capacity is used; blue indi-
cates operating within maximum capacity range, yel-
low indicates operating within reduced capacity
range. Models equipped with a jib have a blue and a
red light only. When moving the platform from one
capacity area to another, one light will go out and
another will come on indicating the correct capacity
for that area. A steady red light indicates you have
exceeded the machines operating radius. You must
immediately stop and ‘’LIFT UP’’ or ‘’TELE IN’’ until
the red light goes out. A blinking red light and a
buzzer sounding indicates you have exceeded the
platform load capacity (personnel, tools, and sup-
plies) and maximum radius. You must immediately
stop all functions and then ‘’LIFT UP’’ or ‘’TELE IN’’
until the red light goes out and the buzzer stops.
Check to make sure the load in the platform does
not exceed the rated capacity.
28. Broken Extend Chain Indicator
The broken extend chain indicator lights in the event
of a broken or lose extend chain in the boom.
