Platform Control Indicator Panel
(See Figure 3-5., Platform Control Indicator Panel)
NOTE: The platform control indicator panel uses different shaped
symbols to alert the operator to different types of opera-
tional situations that could arise. The meaning of those
symbols are explained below.

This illuminator indicates that the chassis is on a slope.
An alarm will also sound when the chassis is on a slope
and the boom is above horizontal. If lit when boom is
raised or extended, retract and lower to below horizontal
then reposition machine so that it is level before continu-
ing operation. If the boom is above horizontal and the
machine is on a slope, the tilt alarm warning light will illu-
minate and an alarm will sound and CREEP is automati-
cally activated.
IF TILT WARNING LIGHT IS ILLUMINATED WHEN BOOM IS RAISED OR
EXTENDED, RETRACT AND LOWER TO BELOW HORIZONTAL THEN
REPOSITION MACHINE SO THAT IT IS LEVEL BEFORE EXTENDING
BOOM OR RAISING BOOM ABOVE HORIZONTAL.
