• 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

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.

ground, and stop the engine.

2. Open the right side cover.

3. Loosen the wing bolt (1).

4. Turn the selector valve lever (2) to change

the pattern.

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.
