INTRODUCTION

Read this manual carefully to learn how to operate and

service your machine correctly. Failure to do so could re-

sult in personal injury or machine damage.

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.

• SI Units (International System of Units) are used in this

manual.

For reference MKS system units and English units are

also indicated in parentheses after the SI units.

Example : 24.5 MPa (250 kgf/cm2, 3560 psi)

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 deal-

er 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 clean-

ness 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 pro-

gram 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 war-

ranty 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 COUN-

TRY. PLEASE DO NOT EXPORT OR OPERATE THIS MA-

CHINE OUTSIDE OF THE COUNTRY OF ITS INTENDED

USE UNTIL SUCH COMPLIANCE HAS BEEN CONFIRMED.

PLEASE CONTACT HITACHI CONSTRUCTION MACHIN-

ERY CO., LTD. OR ANY OF OUR AUTHORIZED DISTRIBU-

TOR OR DEALER IF YOU HAVE ANY QUESTIONS CON-

CERNING COMPLIANCE.

All information, illustrations and specifications in this manual are based on the latest product information available at the
