INTRODUCTION

Read this manual carefully to learn how to operate and

service your machine correctly. Failure to do so could result in personal injury or machine damage.

This standard specification machine can be operated under the following conditions without being modified. Atmospheric Temperature: −20 °C to 40 °C (−4 °F to 104 °F) Altitude: 0 m to 2000 m (0 ft to 6600 ft)

In case the machine is used under conditions other than described above, consult your nearest Hitachi dealer.

This manual should be considered a permanent part of your machine and should remain with the machine when you sell it.

This machine is of metric design. Measurements in this manual are metric. Use only metric hardware and tools as specified.

Right-hand and left-hand sides are determined by facing in the direction of forward travel.

Write product identification numbers in the Machine Numbers section. Accurately record all the numbers to help in tracing the machine should it be stolen. Your dealer also needs these numbers when you order parts. If this manual is kept on the machine, also file the identification numbers in a secure place off the machine.

Use only diesel fuel with quality specified in JIS K-2204, EN-590, ASTM D-975, GOST R52368 or GB252. Failure to use diesel fuel with quality as specified above may allow the engine to emit exhaust gas which cleanness can not conform to the requests in various relevant regulations. In addition, serious damage to the engine may result. Consult with your nearest Hitachi dealer for detailed information.

Warranty is provided as a part of Hitachi’s support program for customers who operate and maintain their equipment as described in this manual. The warranty is explained on the warranty certificate which you should have received from your dealer.

This warranty provides you the assurance that Hitachi will back its products where defects appear within the warranty period. In some circumstances, Hitachi also provides field improvements, often without charge to the customer, even if the product is out of warranty.

Should the equipment be abused, or modified to change its performance beyond the original factory specifications, the warranty will become void and field improvements may be denied.

Setting fuel delivery above specifications or otherwise overpowering machines will result in such action.

Only qualified, experienced operators officially licensed (according to local law) should be allowed to operate the machine. Moreover, only officially licensed personnel should be allowed to inspect and service the machine.

PRIOR TO OPERATING THIS MACHINE, INCLUDING SATELLITE COMMUNICATION SYSTEM, IN A COUNTRY OTHER THAN A COUNTRY OF ITS INTENDED USE, IT MAY BE NECESSARY TO MAKE MODIFICATIONS TO IT SO THAT IT COMPLIES WITH THE LOCAL REGULATORY STANDARDS (INCLUDING SAFETY STANDARDS) AND LEGAL REQUIREMENTS OF THAT PARTICULAR COUNTRY. PLEASE DO NOT EXPORT OR OPERATE THIS MACHINE OUTSIDE OF THE COUNTRY OF ITS INTENDED USE UNTIL SUCH COMPLIANCE HAS BEEN CONFIRMED. PLEASE CONTACT HITACHI CONSTRUCTION MACHINERY CO., LTD.

INVESTIGATE JOB SITE BEFOREHAND

•

When working at the edge of an excavation or on a road

shoulder, the machine could tip over, possibly resulting in serious injury or death.

• Investigate the configuration and ground conditions of the job site beforehand to prevent the machine from falling and to prevent the ground, stockpiles, or banks from collapsing.

• Make a work plan. Use machines appropriate to the work and job site.

• Reinforce ground, edges, and road shoulders as necessary. Keep the machine well back from the edges of excavations and road shoulders.

• When working on an incline or on a road shoulder, em

-

ploy a signal person as required.

• Confirm that your machine is equipped a FOPS cab before working in areas where the possibility of falling stones or debris exist.

• When the footing is weak, reinforce the ground before starting work.

• When working on frozen ground, be extremely alert. As ambient temperatures rise, footing becomes loose and slippery.

• Beware the possibility of fire when operating the machine near flammable objects such as dry grass.

•

Make sure the worksite has sufficient strength to firmly sup-

port the machine.

When working close to an excavation or at road shoulders,

operate the machine with the tracks positioned perpendicular to the cliff face with travel motors at the rear, so that the machine can more easily evacuate if the cliff face collapses.

•

If working on the bottom of a cliff or a high bank is required,

be sure to investigate the area first and confirm that no danger of the cliff or bank collapsing exists. If any possibility of cliff or bank collapsing exists, do not work on the area.

•

Soft ground may collapse when operating the machine on

it, possibly causing the machine to tip over. When working on soft ground is required, be sure to reinforce the ground first using large pieces of steel plates strong and firm enough to easily support the machine.

•

Note that there is always a possibility of machine tipping

over when working on rough terrain or on slopes. Prevent machine tipping over from occurring. When operating on rough terrain or on slopes:

• Reduce the engine speed.

• Select slow travel speed mode.

• Operate the machine slowly and be cautious with ma

-

chine movements.

PREVENT BURNS

Hot spraying fluids:

•

After operation, engine coolant is hot and under pressure.

Hot water or steam is contained in the engine, radiator and heater lines.

Skin contact with escaping hot water or steam can cause

severe burns.

• To avoid possible injury from hot spraying water. DO NOT remove the radiator cap until the engine is cool. When opening, turn the cap slowly to the stop. Allow all pressure to be released before removing the cap.

• The hydraulic oil tank is pressurized. Again, be sure to release all pressure before removing the cap.

Hot fluids and surfaces:

•

Engine oil, gear oil and hydraulic oil also become hot during

operation.

The engine, hoses, lines and other parts become hot as well.

• Wait for the oil and components to cool before starting any maintenance or inspection work.

505-E01B-0498

REPLACE RUBBER HOSES PERIODICALLY

•

Rubber hoses that contain flammable fluids under pressure

may break due to aging, fatigue, and abrasion. It is very difficult to gauge the extent of deterioration due to aging, fatigue, and abrasion of rubber hoses by inspection alone.

• Periodically replace the rubber hoses. (See the page of “Periodic replacement of parts” in the operator’s manual.)

•

Failure to periodically replace rubber hoses may cause a fire,

fluid injection into skin, or the front attachment to fall on a person nearby, which may result in severe burns, gangrene, or otherwise serious injury or death.
