BEFORE READING THIS MANUAL

This  manual  gives  details  of  the  operation  and  methods  of  inspection  and  maintenance  for  this  machine  that
must be obeyed in order to use the machine safely. Most accidents are caused by the failure to follow funda-
mental safety rules for the operation and maintenance of machines.
Read, understand and follow all precautions and warnings in this manual and on the machine before performing
operation and maintenance. Failure to do so may result in serious injury or death.
Komatsu  cannot  predict  every  circumstance  that  might  involve  a  potential  hazard  when  the  machine  is  used.
Therefore, the safety messages in this manual and on the machine may not include all possible safety precau-
tions.
If you perform 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 the prohibited uses or actions described in this manual. It is dangerous to perform im-
proper operation and maintenance of the machine. It may cause serious injury or death.
If you sell the machine, be sure to give this manual to the new owner together with the machine.
Always keep this Operation and Maintenance Manual in the indicated location so that all relevant personnel can
read it at any time.
Keep  it  in  the  magazine  box  on  the  left  side  of  the  operator's
seat.

If this manual is lost or damaged, contact Komatsu or your Komatsu distributor and tell them about the machine
model name and the serial No. immediately to arrange for its replacement.
For details regarding the machine model name and the serial No., see the machine serial No. plate. In order to
arrange the proper Operation and Maintenance Manual, you will need to provide the machine model name and
the serial No.
This manual uses the International System of 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 its publication. Continuing improvements in the design of this machine may lead to
additional changes that are not reflected in this manual. If there is any question or suggestion, consult your Ko-
matsu distributor.
The numbers in the illustrations correspond to the numbers in ( ) in the text. (Example: 1 → (1))
Komatsu delivers machines that comply with all applicable regulations and standards of the country to which it
has been shipped. If this machine 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 regulations of your country, consult your Komatsu distributor before
operating the machine.
