• 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 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 mounted when a bucket wider than a 500W bucket is

mounted. Failure to mount the swing stopper may result in the bucket hitting the

machine body.

HYDRAULIC BREAKER

Cautions on operating

HYDRAULIC BREAKER

For handling of the breaker, read the

hydraulic breaker’s manual, provided

separately.

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.

avoid pounding the air.

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.

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

hydraulic system. To improve the service

life of the hydraulic systems, be sure to

replace the hydraulic oil and return filter

element after the number of hours shown

on the diagram below.

• When replacing the hydraulic oil, clean the

suction strainer.

TRAVEL ALARM

Fuse layout and circuits protected

TRAVEL ALARM

The alarm sounds while the machine is

traveling and stops when the machine stops

traveling.

If the alarm does not sound when the

machine travels, the fuse may be blown.

Inspect the fuses.

If the fuse blows again soon after

replacement, then the electric system is

likely faulty. It may pose a fire hazard if

not properly repaired. Contact your sales

or service dealer for advice.

1. Turn the starter key to the OFF position to

stop the engine.

2. Open the fuse box cover (1).

3. Check for fuse.

4. If a fuse is blown, replace it with a spare

fuse of the same capacity.

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” on page

5-50.

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.

TAKEUCHI SECURITY SYSTEM

STARTING THE ENGINE

TAKEUCHI SECURITY SYSTEM

The Takeuchi Security System is a system

that allows only registered starter keys to be

used for starting the engine.

The engine cannot be started with any

unregistered or counterfeit starter keys. If a

registered starter key is lost or stolen, you

can set the system to delete the registered

key information, so that the lost or stolen key

cannot be used to start the engine. Although

machine theft cannot be completely

prevented, the system certainly helps reduce

the risk of theft.

The engine can be started using the normal

method with a registered BLACK key.

The engine cannot be started using the RED

STARTER KEY

master key.

Refer to Chapter 3, “Starting and stopping

the engine”.

If an attempt is made to start the engine

with an unregistered key:

There are two types of starter key, red and

black, which can be registered in the

Takeuchi Security System.

The red key is the master key. The black key

is the starting key.

If an unregistered starter key is turned from

the OFF to the ON (ACC) position, the

message “Authentication failure” appears

and the alarm starts sounding.

If this attempt is repeated five times in a row,

the horn sounds for two minutes, and the

engine cannot be started. The horn stops

when the key is turned to the OFF position.
