1. Before returning to normal use, install the pin in work-
ing position (1) .
2. When you use the hydraulic breaker, make sure that
the telescopic dipper is retracted and the pin is in work-
ing position
(1) .
NOTE: Figure A applies to models 580T/580ST with
overlapping cylinder boom, 590ST, and 695ST. Figure
B applies to models 580T/580ST with in-line cylinder
boom.
3. When using a toothed bucket to break hard ground,
avoid extending the dipper beyond 60 m ( 1.96 ft ).
4. When digging in wet soil or mud and the bucket needs
to be cleaned, do not knock the bucket against the
ground with the dipper extended.
5. Avoid overloading the attachment by using a bucket
which is too big in harsh working conditions, as this
will reduce the useful life of the machine.
6. Do not bottom-out the swing cylinder with the dipper
extended.
7. For safety reasons, when working on sloping ground,
do not swing the boom to dump the bucket contents
on the side sloping down.
NOTICE: Make sure that the rear windows are closed.
Always wear your seat belt for protection in the event
of the machine overturning. Never try to jump from the
machine and always remain in the cab.
8. When operating with the dipper fully extended, ensure
that the bucket does not receive a sharp impact which
will cause distortion of the cylinder rod.
