INTRODUCTION
Read this manual carefully to learn how to operate and
service your machine correctly. Failure to do so could
result in personal injury and/or machine damage.
This standard specification machine can be operated
under the following conditions without being modified.
Atmospheric Temperature: -20 °C to 50 °C (-4 °F to 122 °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 authorized 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.
• 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, 3550 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 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 or ASTM D-975 which contents 15 ppm or lower
sulfur.
Also use fuel that complies with solid contamination level
of class 18/16/13 of ISO4406-1999 (solid contamination
includes dust). If the fuel specified above is not used,
exhaust gas that exceeds the regulation values may be
discharged, causing serious problem on the engine.
Consult your authorized dealer.
