IF THE BATTERY GOES DEAD
Disconnecting the jumper cables
Once the dead machine is successfully
running, remove the jumper cables by
following the same steps as for connection in
the reverse order.
1. Disconnect the clip of jumper cable (B)
from the engine block of the dead
machine.
2. Disconnect the other clip of jumper cable
(B) from the negative (-) battery terminal of
the booster vehicle.
3. Disconnect the clip of jumper cable (R)
from the positive (+) battery terminal of the
booster vehicle.
4. Disconnect the clip of jumper cable (R)
from the positive (+) battery terminal of the
dead machine.

Note: Fusible links are large type fuses used
in high current applications. Like a regular

• Before removing a heavy object, be sure
to put a support to it. When lifting with a

There is no need to flush the hydraulic oil

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
5-43.
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”.
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.
