Stability
Machine stability is based on two (2) conditions which are
called FORWARD and BACKWARD stability. The machine’s
position of least FORWARD stability is shown in (See Figure
4-2.), and its position of least BACKWARD stability is shown
in (See Figure 4-3.)
TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD
MACHINE OR OPERATE THE MACHINE ON A SURFACE OUT-OF-LEVEL
MORE THAN THE RATED 3 DEGEES.
4.3 CAPACITY SELECT
The Boom Control System allows the operator to select opera-
tion in a 500 pound (230 kg) capacity restriction envelope or a
1000 pound (450 kg) capacity restriction envelope. The opera-
tor selects the desired capacity restriction by positioning the
Capacity Select switch on the platform console. The Capacity
Indicator shows the capacity selected, and both capacity lights
will flash and an alarm sound if the platform is out of the
selected capacity range.
NOTE: Operation in the 1000 pound (450 kg) envelope requires
the jib to be fixed in the centered position.
