★
Heavy optional equipment probably re-
quires a larger space for swinging op-
eration. There might be the danger of
impacting other objects if the swinging
range has not been calculated accu-
rately. A larger space must be prepared
before performing the swinging opera-
tion.
★
When the lifting of heavy optional
equipment is held, the distance mov-
ing downward is relatively longer due
to gravity. In this case, it should be
lowered to the ground instead of being
held in air.
★
Never swing, lower or stop your ma-
chine suddenly in order to prevent it
from tipping over.
★
Never extend or retract the boom cylin-
der suddenly in order to prevent impact
that may cause the machine to tip.
