SECTION 3 - MACHINE CONTROLS AND INDICATORS
NOTE: When positioned to Manual, boom functions will be stopped
when the envelope limits are reached. When this occurs, operate
a different function or select the automatic position.
NOTE:
Depending upon the angle of the chassis and the angle of the
boom, swing left or swing right may be disallowed while in the
Manual mode. The BCS light will illuminate and further attempts
to swing in the disallowed direction will cause the BCS to flash.
When this occurs the only choices are to swing in the opposite
