INSTRUMENT PANEL
Control Symbols
The operator must understand the function and oper-
ation of each instrument and control. Many control
functions are identified with international symbols
that the operator should learn to recognize immedi-
ately. This knowledge is essential for proper and safe
operation.
Items that are marked optional do not apply to every
truck.
The following symbols are general indicators and
may appear in multiple locations and combinations
on the instrument panel.
Most switches have two LED lights inside them, one
amber and one green in color. The amber is located
in the top portion of the switch and indicates that
function has been activated. The green LED is
located in the lower portion of the switch and indi-
cates that function has not been activated.
• To activate a function, push on the top portion of
the switch. At this time, the amber LED will be
illuminated, and the green LED will be OFF.
• To de-activate a function, push on the lower
portion of the switch. At this time, the green LED
will be illuminated, and the amber LED will be
OFF.
NOTE: The green LED light in the hazard light
switch, head light switch and the ladder light switch
will be illuminated when battery power is connected
to the truck. The LED lights in the other switches will
illuminate when the key switch is turned to the ON
position.
