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.

ATTACHMENT COMBINATION TABLE
ATTACHMENT COMBINATION TABLE
The table below shows which bucket should be installed when the machine is using a
standard arm, middle arm or long arm. Select a proper bucket by following the table.
• Consult with Takeuchi before installing an optional attachment.
• Do not use any attachments not approved by Takeuchi. Doing so may cause safety
problems. Or, it may adversely affect the machine’s operation or service life.
• We will not be held responsible for any injuries, accidents or damage to its products
caused by the use by a non-approved attachment.
• The swing stopper must be installed when a bucket wider than a 640W (standard)
bucket is installed. Failure to do so may result in the bucket hitting the machine body.

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.

REPLACING THE HYDRAULIC OIL WITH
BIODEGRADABLE OIL
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.
Flushing
To be performed by a Takeuchi sales or
service outlet
1. Drain the hydraulic oil (mineral oil) from the
hydraulic oil tank and clean the inside of
the tank and suction strainer.
Refer to “Replacing the hydraulic oil and
cleaning the suction strainer”.
2. Remove the cylinder hoses and drain the
hydraulic oil (mineral oil) from inside the
cylinders.
3. Supply new biodegradable oil to the
hydraulic oil tank.
