TROUBLESHOOTING

If the Battery Goes Dead

Connecting the jumper cables

IMPORTANT: Set the starter keys of both
the rescue vehicle and problem vehicle
to the OFF position.

1. Connect the clip of jumper cable (R) to

the problem vehicle’s “+” terminal.

2. Connect the other clip of jumper cable (R)

to the rescue vehicle’s “+” terminal.

3. Connect the clip of jumper cable (B) to

the rescue vehicle’s “–” terminal.

4. Connect the other clip of jumper cable (B)

to the problem vehicle’s engine block.
Connect the clip as far from the battery as
possible.

Starting the engine
1. Check that the clips are securely

connected to the terminals.

2. Start the rescue vehicle’s engine and run

it at high speed.

3. Start the problem vehicle’s engine.

The following symptoms indicate that the
battery is dead:

The starter motor does not turn or turns
weakly, and the engine does not start.

The horn is weak.

Procedure
Use jumper cables and start the engine using
the rescue vehicle’s battery.

WARNING

Use jumper cables only in the
recommended manner. Improper use
of jumper cables can result in battery
explosion or unexpected machine
motion.
• Do not let the problem vehicle and

rescue vehicle touch each other.

• Do not let the “+” and “–” clips of the

jumper cables touch each other.

• Connect the jumper cables to the “+”

terminals first, and disconnect them
from the “–” terminals (ground) first.

• Connect the final clip of the jumper

cable to a point as far away from the
battery as possible.

Use safety glasses when using jumper
cables to start the machine.

IMPORTANT: Use jumper cables and
clips of a size suited to the battery’s
capacity. Do not used damaged or
corroded jumper cables and clips.
IMPORTANT: The rescue vehicle’s
battery must have the same capacity as
the problem vehicle’s battery.
IMPORTANT: Connect the clips securely.

TROUBLESHOOTING

Bleeding the Air from the Fuel
System

1. Supply fuel.

2. Turn the starter key to the ON position and

hold it there for about 20 seconds.
The automatic air bleeder bleeds the air
from the fuel system.

Supplement: Air in the fuel system can
make it difficult to start the engine and cause
engine problems. Also bleed the air when
the fuel tank is emptied or air in the fuel
system.

Disconnecting the jumper cables
Once the engine starts, disconnect the
jumper cables following the connection
procedure in reverse order.

1. Disconnect the clip of jumper cable (B)

from the problem vehicle’s engine block.

2. Disconnect the other clip of jumper cable

(B) from the rescue vehicle’s “–” terminal.

3. Disconnect the clip of jumper cable (R)

from the rescue vehicle’s “+” terminal.

4. Disconnect the other clip of jumper cable

(R) from the problem vehicle’s “+” terminal.

Recharging
Have a Takeuchi sales or service outlet
recharge batteries that have gone dead.

To Lower the Boom

1. Loosen the bolts and remove cover (1).

2. Put mark (M) on the plug of the port relief

valve (2) and set screw (3).

3. Gripping the set screw (3) with a

hexagonal wrench so that it does not turn
together with the lock nut (4), loosen the
lock nut (4).

4. Turn the set screw (3) slowly one turn to

lower the boom.

5. Check for safety and machine stability.
6. Turn the set screw (3) back to its original

position.

7. Gripping the set screw (3) with a

hexagonal wrench so that it does not turn
together with the lock nut (4), tighten the
lock nut (4).
Tightening torque:

27 to 31 N·m (20 to 23 ft-lb.)

8. Reinstall the cover (1).

If the hoe attachment must be lowered to
the ground while the engine is stopped, use
the following procedure to do so.
This operation is dangerous and requires
experience. Have it performed by a Takeuchi
sales or service outlet.

When equipped with accumulator (option):

Towing

WARNING

When towing, selecting the wrong wire
rope, inspecting improperly, or towing in
the wrong way could lead to accidents
resulting in serious injury or death.

The wire rope breaking or coming
detached could be extremely
dangerous. Use a wire rope suited for
the required towing force.

Do not use a wire rope that is kinked,
twisted or otherwise damaged.

Do not apply strong loads abruptly to
the wire rope.

Use safety gloves when handling the
wire rope.

Make sure there is an operator on the
machine being towed as well as on the
machine that is towing.

Never tow on slopes.

Do not let anyone near the wire rope
while towing.

Towing the Machine
Use the procedure described below to tow
heavy objects or the machine itself if it should
get stuck in the mud and not be able to get
out on its own.

1. Fasten the wire rope to the frame.
2. Place splints or other objects between the

wire rope and frame to prevent the
machine and wire rope from getting
damaged.

3. Move the machine to tauten the wire rope.
4. Move the machine slowly and tow.

Using the light load towing hole

IMPORTANT: Be sure to follow all the
steps below closely when using the light
load towing hole to tow. Failure to heed
even one of the steps may cause damage
to the light load towing hole or other parts
of the frame.

Maximum pulling force:

43200 N (9700 lb) or less

1. Attach the wire rope to the shackle (1).
2. Fasten the shackle (1) to the light load

towing hole (2).

3. Attach the wire rope to the object to be

towed.

4. Make the wire rope horizontal and line up

straight with the travel frame.

5. Move the machine to tauten the wire rope.
6. Move the machine slowly and tow.
