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 Extend-A-Reach have
a blue and a red light only. When moving the plat-
form from one capacity area to another, one light will
go out and another will come on indicating the cor-
rect capacity for that area. A steady red light indi-
cates 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 supplies) 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.
3.4 PLACARDS AND DECALS
Read and understand all placards and decals. Do not
operate any machine on which DANGER, WARNING,
CAUTION, or INSTRUCTION PLACARDS OR DECALS
ARE MISSING OR ILLEGIBLE. Replace placards and
decals if damaged, missing, or illegible.
Decals are made of Lexan Pressure Sensitive Adhesive
with a protective film on the front. Remove the damaged
decal and thoroughly clean the surface before installing a
new decal. Simply peel off the backing and press the
decal on to the surface.
NOTE: Placards and Decals can be ordered by using the
part numbers located by each placard or decal. See
Figure 3-5., Caution, Danger, Warning Decal Loca-
tion - Sheet 1 of 2 and Figure 3-6., Caution, Danger,
Warning Decal Location - Sheet 2 of 2.
