Intelligent Floating Boom Control (If Equipped)
NOTE:
1.
The boom operating joystick must be in
"NEUTRAL" position before operating the
Intelligent Floating Boom mode selector switch.
2.
If the tracks are raised up, do not select and use
the Intelligent Floating Boom mode. This could
cause the tracks to suddenly lower resulting in
death or serious injury.
3.
When the boom operating joystick is in boom
lowering position and the bucket or other
attachment is in contact with the ground, do not
use Intelligent Floating Boom mode (temporary
reset button). If the tracks are raised and the
Intelligent Floating Boom mode has been
selected, pressing the temporary reset button
can cause a tip over when the boom lowering
control is activated at the same time.
See "Intelligent Floating Boom Switch (If Equipped)"
on page 2-18 for further information.
Intelligent Floating Boom Mode
The boom can move freely "UP" and "DOWN" when any
external force up or down is applied to the boom. Applications
like using a breaker attachment, leveling, or stone gathering are
easier and more convenient.
Operating a Breaker
The boom can freely move "DOWN". The breaker can be
operated with only the weight of the work group on the front
without additional force, resulting in less shock and vibration,
and extended service life of the breaker. The breaker will remain
in constant contact with the object.
WARNING
AVOID DEATH OR SERIOUS INJURY
•
Activating the Intelligent Floating Boom Control with
the tracks raised up can cause the machine to drop
suddenly.
•
Do not activate Intelligent Floating Boom Control when
tracks are raised.
•
Do not raise tracks when control is activated.
