SAFETY

PRECAUTIONS ON MAINTENANCE

Cautions when refueling

Handling of hoses

Oil leak or fuel leak can cause a fire.

• Do not twist, bend or hit the hoses.

• Never use twisted, bent or cracked pipes,

tubes or hoses; otherwise, they may burst.

• Retighten loose connection.

Be careful with hot and pressurized

components

• Do not smoke or permit open flames while

fueling or near fueling operations.

• Never remove the fuel cap or add fuel

when the engine is running or still hot. Do

not spill fuel on the hot surface of the

machine.

• Fill the fuel tank in a well ventilated place.

• Do not fill the fuel tank to capacity. Allow

room for oil expansion.

• Clean up spilled fuel immediately.

• Securely tighten the fuel filler cap. If the fuel

• The engine coolant, hydraulic oil and other

oils are also hot and under high pressure.

Be careful not to touch the hydraulic oil

when loosening the cap or plug. Working

on the machine under these conditions

could result in burns or injuries due to the

hot oil spurting out.

1-32

SAFETY

PRECAUTIONS ON MAINTENANCE

Be careful with hot cooling systems

Be careful with oil internal pressure

Pressure is maintained in the hydraulic circuit

long after the engine has been shut down.

• Completely relieve the internal pressure

before performing maintenance work.

Do not remove the radiator cap or the drain

plug when the cooling water is hot. Stop the

engine and wait until the engine and the

cooling water cool. Then, slowly loosen the

radiator cap to release the internal pressure

and remove it.

• The hydraulic oil is high enough pressure to

penetrate the skin or eyes and cause

serious injury, blindness or death.

Remember that the hydraulic oil escaping

from a small hole is almost invisible. When

checking for leaks, wear protective goggle

and thick gloves, and use a paperboard or

plywood to keep your skin from oil

spurting.

If oil penetrates the skin, it must be

surgically removed within a few hours by a

doctor familiar with this type of injury.

SAFETY

PRECAUTIONS ON MAINTENANCE

Disconnect the battery wiring

• Do not charge a battery or jump-start the

engine if the battery is frozen; otherwise it

may explode. Warm the frozen battery to

15°C (60°F) before use.

• Do not use the battery when the fluid level

is below the lower level limit. Doing so will

hasten the deterioration of the internal

portions of the battery and shorten the

battery life. It also can cause rupturing

(explosion).

• Do not add the distilled water above the

upper level limit. Doing so could cause the

fluid to leak. This fluid can cause skin

not clean with a dry cloth; otherwise it

could cause static electricity to build up,

resulting in ignition or explosion.

Use caution when handling batteries

• Batteries contain sulfuric acid which will

damage the eyes or skin in case of

contact.

· If eye contact occurs, flush immediately

with clean water and get prompt medical

attention.

· If accidentally swallowed, drink large

quantities of water or milk and call a

physician immediately.

· If acid contacts skin or clothing, wash off

immediately with a lot of water.

• Wear protective goggle and gloves when

working with batteries.

• Batteries generate flammable hydrogen

gas which may explode. Keep away from

flame, sparks, fire or lighted cigarettes.

• When checking the level of the battery

fluid, use a flashlight.

• Be sure to stop the engine by turning off

the starter switch before inspecting or

handling the battery.

• Be careful not to let metal tools or any

metal objects come into contact with the

battery terminals and cause a short circuit.

• Loose battery terminals may result in

sparks. Be sure to fasten terminals tightly.

• Make sure the battery caps are tightened

securely.

SAFETY SIGNS (DECALS)

For the safety of the operator and the personnel working around the site, safety signs (decals)

are placed at certain locations on the machine as shown below. Walk around the machine with

this manual, and check the content and location of these safety signs. Review these signs and

the operating instructions in this manual with your machine operators.

• Keep the signs clean and legible. If any of the safety labels is peeling or damaged and

becomes difficult to read, replace it with a new one. Please include your product serial

number when ordering a new sign from the Takeuchi service agent.

• When a part/unit to which a safety sign is attached is replenished, a new sign must be

attached to the new part/unit.
