BEFORE READING THIS MANUAL
This manual gives details of the operation and methods of inspection and maintenance for this excavator that must
be obeyed in order to use the excavator safely. Most accidents are caused by the failure to follow fundamental
safety rules for the operation and maintenance of excavators.
Read, understand and follow all precautions and warnings in this manual and on the excavator before performing
operation and maintenance. Failure to do so may result in serious injury or death.
Komatsu cannot predict every circumstance that may involve a potential hazard when the excavator is used.
Therefore, the safety messages in this manual and on the excavator may not include all possible safety precau-
tions. If you carry out any operation, inspection or maintenance under conditions that are not described in this
manual, understand that it is your responsibility to take the necessary precautions to ensure safety. In no event
should you or others engage in prohibited uses or actions described in this manual. Improper operation and main-
tenance of the excavator can be hazardous and could result in serious injury or death.
If you sell the excavator, be sure to give this manual to the new owner together with the excavator.
This manual uses the international units (SI) for units of measurement. For reference, units that have been used in
the past are given in ( ).
The explanations, values, and illustrations in this manual have been prepared based on the latest information
available as of the date of publication. Continuing improvements in the design of this excavator may lead to addi-
tional changes that are not reflected in this manual. Consult Komatsu or your Komatsu distributor for the latest
available information concerning your excavator or with questions regarding information contained in this manual.
The numbers in circles in the illustrations correspond to the numbers in ( ) in the text. (For example: Komatsu delivers excavators that comply with all applicable regulations and standards of the country to which it has been shipped.
If the excavator has been purchased in another country, it may
lack certain safety devices and specifications that are necessary
for use in your country. If there is any question about whether
your product complies with the applicable standards and regula-
tions of your country, consult Komatsu or your Komatsu distributor
before operating the excavator.
Always keep the Operation and Maintenance Manual in the stor-
age space provided inside the operator’s cabin (see Fig.1-1) so that all relevant personnel can read it at any time. If this manual is
lost or damaged, contact your distributor immediately to arrange
for its replacement
