• We will not be held responsible for any
injuries, accidents or damage to its
products caused by the use by a non-
approved attachment.
• Select a firm, level work area. Also, be
sure to park in a well ventilated place.
• Clear obstacles and dangerous objects,
and clean up spilled fuel immediately.
• When hoisting, be sure to designate a
person to act as a signalman.
Follow the instructions of the signalman
regarding the procedure and measures.
• When it is necessary to temporally
place a heavy object or an attachment
on the ground during removal or
installation, be sure to place it in a
stable position.
• Keep everyone out of the area when
hoisting. There is a hazard of objects
falling or contacting with people in the
area.
• Use a crane to move heavy objects (25
kg (55 lb.) or greater).
• Before removing a heavy object, be sure
to put a support to it. When lifting with a
crane, pay attention to the center of
gravity of the load to keep the machine
in balance.
• Do not operate the machine while the
load is lifted by a crane stand.

REPLACING THE HYDRAULIC OIL
REGULARLY
When a hydraulic breaker is used, the oil
deteriorates more quickly than that used for
a usual operation. Be sure to replace the
hydraulic oil and the return filter elements.
• Failure to replace these in time can lead to
damage to the machine and the breaker

life of the hydraulic systems, be sure to

Mixing mineral oil with biodegradable oil will
result in a decrease of the hydraulic oil’s
performance as well as a decrease in
biodegradability and safety. The hydraulic oil
system must be flushed as described below
before supplying the biodegradable oil. This
operation is dangerous and requires
experience. Have it performed by a Takeuchi
sales or service outlet.
