HYDRAULIC BREAKER
For handling of the breaker, read the
hydraulic breaker’s manual, provided
separately.
HYDRAULIC BREAKER
Do not use the breaker when the crawler
width is narrowed!
• Always operate the machine with the
crawler width extended to 1500 mm
(59.1 in.) to maximize the machine
stability. If the machine is operated with
the crawler width narrowed 1100 mm
(43.3 in.), the machine may tip over due
to its poor stability.
• If the machine must be operated with
the narrowed crawler width 1100 mm
(43.3 in.), traveling should be done after
folding the hoe attachment, lowering the
boom to lower the center of gravity and
keeping the machine facing forward.
When an optional attachment, such as a
breaker, tilted bucket or clamshell, is
operated, be sure that the crawler width is
extended to 1500 mm (59.1 in.).
IMPORTANT: When installing an
attachment, make sure that it is
appropriate for the machine being used.
Contact your sales or service dealer for
advice on selecting attachments.
Cautions on operating
• Start the engine and run it at 75% of the
maximum speed.
• Pound with the chisel pressed
perpendicular to the surface to be
pounded.
• When pounding, press the chisel properly
against the object to be broken so as to
avoid pounding the air.
