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. 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 manual should be considered a permanent part of your machine and should remain with the machine when you sell it. 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. 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/cm 2 , 3560 psi) Right-hand and left-hand sides are determined by facing in the direction of forward travel. 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. 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.
