GENERAL
Cautions on working on the machine
L3A005
• When performing maintenance on the machine,
clean up the foot area and strictly observe the
following so as not to fall:
• Do not spill oil or grease.
• Do not leave tools laying around.
• When walking, watch your step.
• Never jump off the machine. Use the steps and
handrails when climbing on and off the machine,
and always support your body at three points with
your hands and feet.
• Use protective equipment as required by job conditions.
Use caution when fueling
Handling of hoses
Fuel, oil or hydraulic fluid leaks can cause a fire.
• Do not twist, bend or hit the hoses.
• Never use twisted, bent or cracked hoses, tubes and
pipes. They may burst.
• Retighten loose connections.
Be careful with hot and pressurized
components
Stop the engine and allow the machine to cool down
before performing inspection and maintenance.
• The engine, muffler, radiator, hydraulic lines, sliding parts and many other parts of the machine are
hot directly after the engine is stopped. Touching
these parts will cause burns.
• The engine coolant, oil and hydraulic fluid are also
hot and under high pressure.
Be careful when loosening caps and plugs. Working on the machine under these conditions could
result in burns or injuries due to the hot oil spurting
out.
• Do not smoke or permit open flames while fueling
or near fueling operations.
• Never remove the fuel cap or refuel with the engine
running or hot. Never allow fuel to spill on hot
machine components.
• Maintain control of the fuel filler nozzle when
filling the tank.
• Do not fill the fuel tank to capacity. Allow room for
expansion.
• Clean up spilled fuel immediately.
• Tighten the fuel tank cap securely. Should the fuel
cap be lost, replace it only with the original
manufacturer’s approved cap. Use of a non-approved cap without proper venting may result in
pressurization of the tank.
• Never use fuel for cleaning purposes.
• Use the correct fuel grade for the operating season.
Be careful with hot cooling systems
Do not remove the radiator cap or drain plugs when
the coolant is hot. Stop the engine, let the engine and
radiator cool and loosen the radiator cap or drain plugs
slowly.
I-6REV. 1

GENERAL
Be careful with fluids under pressure
Pressure can be maintained in the hydraulic circuit
long after the engine has been shut down.
• Release all pressure before working on the hydraulic system.
• Hydraulic fluid under pressure can penetrate the
skin or eyes and cause injury, blindness or death.
Fluid escaping from a small hole can be almost
invisible. Wear a safety goggles and heavy gloves
and use a piece of cardboard or wood to search for
suspected leaks.
If fluid is injected into the skin, it must be removed
within a few hours by a doctor familiar with this
type of injury.
Release all pressure before working on
the hydraulic system
Oil may spurt out if caps or filters are removed or
pipes disconnected before releasing the pressure in
the hydraulic system.
• Gradually loosen the vent plug to relieve tank
pressure.
• Move all the control levers and pedals several
times in all directions to release the pressure from
the working equipment circuitry. (For link type
controls)
• When removing plugs or screws or disconnecting
hoses, stand to the side and loosen slowly to gradually release the internal pressure before removing.
High pressure nitrogen gas is enclosed in the accumulator and incorrect handling could possibly bring
about serious injury due to explosion. The following
matters should be strictly observed:
• Do not disassemble.
• Do not bring close to fire or throw into a fire.
• Do not make hole, weld, or fuse.
• Do not subject to shock such as hitting or rolling.
• At time of disposal, it will be necessary to release
the enclosed gas. Please contact a Takeuchi sales or
service agent.
Be careful with grease under pressure
E3A6201
The track adjuster contains highly pressurized grease.
If the tension is adjusted without following the prescribed procedure, the grease discharge valve may fly
off, resulting in injury.
• Loosen the grease discharge valve slowly. Do not
unfasten it more than one full turn.
• Do not put your face, arms, legs or body in front of
the grease discharge valve.
Disconnect the battery
Handling of the Accumulator
Disconnect the battery before working on the electrical system or doing any welding. Remove the negative (–) battery cable first. When reconnecting the
battery, connect the negative (–) battery cable last.

GENERAL
Avoid battery hazards
• Batteries contain sulfuric acid which will damage
eyes or skin on contact.
• If acid contacts eyes, flush immediately with
clean water and get prompt medical attention.
• If acid is accidentally swallowed, drink large
quantities of water or milk and call a physician
immediately.
• If acid contacts skin or clothing, wash off imme-
diately with clean water.
• Wear safety glasses and gloves when working with
batteries.
• Batteries generate flammable and explosive gases.
Keep arcs, sparks, flames and lighted tobacco
away.
• Use a flashlight to check battery electrolyte level.
• Stop the engine and shut off electrical equipment
while inspecting or handling the battery.
• Do not short circuit the battery posts with metal
items.
• Always unfasten the negative (–) battery cable first
when disconnecting the battery cable. Always connect the negative (–) battery cable last when fastening the battery cable.
• Loose battery terminals may result in sparks. Be
sure to fasten terminals tightly.
• Make sure the vent caps are tightened securely.
• Do not charge a battery or jump-start the engine if
the battery is frozen. Warm to 15°C (60°F) or the
battery may explode.
Checks after maintenance
• Gradually raise the engine speed from a low idle to
maximum speed and check that no oil or air is
leaking from serviced parts.
• Move the controls and check that the machine is
operating properly.
Disposing of wastes
• Funnel spent fluids from the machine into containers. Disposing of fluids improperly destroys the
environment.
• Follow the prescribed regulations when disposing
of oil, fuel, engine coolant, refrigerant, solvents,
filters, batteries or other harmful substances.
Have a Takeuchi service agent repair
welding cracks or other damage
Ask a Takeuchi service agent to repair any welding
problems which are detected. If not feasible, make
sure the welding is done by a qualified person in a
properly equipped workplace.
Safety signs
• Keep all safety signs clean and legible.
• Replace all missing, illegible or damaged safety
and warning signs.

GENERAL
CAUTIONS DURING DISASSEMBLY AND
ASSEMBLY
1. Clean the machine before disassembly operation.
2. Before disassembly, check the machine condi-
tions and record them.
• Model, Machine Serial Number, Hourmeter
• Reason for Repairs, Repair History
• Dirtiness of Filters
• Fuel and Oil Conditions
• Damage to each parts, etc.
3. To make reassembly operations easy, make match-
ing marks at the necessary points.
4. Clean all disassembled parts and new parts, then
arrange them in the proper sequence.
5. Be sure to replace all seals and cotter pins, etc.,
with new parts.
6. Keep parts which should not come in contact with
oil and water separate from parts with oil on them.
• Electrical Parts, Rubber, V-Belts, etc.
CAUTIONS DURING REMOVAL AND
INSTALLATION OF THE HYDRAULIC UNITS
1. Make sure that the temperature of the hydraulic
oil has dropped.
2. To prevent a loss of flow of the hydraulic oil, the
residual pressure in the piping and the internal
pressure in the hydraulic tank should be released.
3. Be sure to install caps or plugs on all openings in
the hydraulic unit to prevent dirt from getting into
the unit through the openings.
PLUG
PLUG
7. When installing bearings, bushings and oil seals,
as a rule, use a press. When a hammer, etc., is
used, it leaves bruises.
8. Wipe all joining surfaces clean so that there is no
dirt or dust adhering to them.
9. Wrap seal tape from the front end, Wrapping it
tight and leaving 1 or 2 threads bare, Overlap the
tape by about 10 mm.
SEALING TAPE
LEAVE 1 OR 2 THREAD MARGIN
4. It is easy to mistake hydraulic oil adhering to the
hydraulic unit for an oil leak, so wipe the unit off
thoroughly.
5. Be sure that no damage is done to the plating on
the rod in the hydraulic cylinder.
6. As a rule, removal and installation of the hydraulic cylinder should be done with the rod fully
retracted.
7. Be sure to bleed the air after replacing the hydraulic oil or removing any of the hydraulic devices.
“III. Machine Configuration, Hydraulic System”
10. When fitting the snap rings, the bigger, rounder
side of their circumferences should face the mating surfaces.

GENERAL
CAUTIONS DURING REMOVAL AND
INSTALLATION OF PIPING
1. When hydraulic hoses are installed, tighten them
once to the prescribed torque, then loosen them
slightly and retighten them to the prescribed
torque.
• Tighten the fittings after the installation sur-
faces fit snugly together.
• Pieces wrapped with seal tape are excluded.
2. Use 2 spanners, each on an opposite side, to
remove and tighten fittings so that the hoses or
steel pipes are not twisted.
HANDLING OF SEALS
1. Clean the grooves for O-rings and if there is any
burr, etc., remove it.

2. Be careful not to twist O-rings. If an O-ring is
twisted, remove the twist with the fingertips.
3. During insertion, be careful not to damage the
seal.
3. After installation of hydraulic hoses or steel pipes,
apply the maximum working pressure 5 or 6 times
and confirm that there is no leakage.
4. Handling of Floating Seals
• Wipe all oil off the O-ring and housing of the
floating seal.
• When assembling, apply a thin coating of gear
oil to the contact surface of the housing.
• After assembly, turn the seal 2 or 3 times to get
it to fit snugly.
5. Apply grease to the lip of the oil seal.
• This is to prevent wear when it is first started up
after assembly.

In regard to Standard Values and Allowable Values
The terms used in the items “Servicing Standards” and “Standards for Judging Performance” have the following
meanings.
Standard Value .........This indicates the standard value for the new machine at the time of shipping from the factory.
It should be used as the target value for maintenance work after operation.
Allowable Value....... The dimensions of parts change during use because of wear and deformation. Also, the
performance of pumps, motors, and other hydraulic equipment drops, and this is the
estimated value indicating the use limit for the respective part. It is decided under reference
to the standard at the time of shipping, the results of various tests, etc. As the use conditions,
the degree of repairs, etc., differ for each machine, these should be combined and used as
reference for servicing standards and standards for judging performance.
* Do not use the standard values and the allowable values as standards for customer claims.
