ATTACHMENTS AND OPTIONS - GENERAL INFORMATION
ATTACHMENTS AND OPTIONS - GENERAL
SAFETY FIRST
If attachments or options other than those authorized by Komatsu are installed, this will not only affect the life of
the machine, but will also cause problems with safety.
When installing attachments not listed in this Operation and Maintenance Manual, contact your Komatsu distribu-
tor first.
If you do not contact Komatsu, we cannot accept any responsibility for any accidents or failures.
General precautions
Attachments are powerful tools. To prevent serious injury or damage, use the attachment correctly.
Read the instruction manual for the attachment thoroughly, and do not use this attachment unless you
are sure that you have understood the guides completely.
If you lose the instruction manual, always ask the manufacturer or attachment sales company for a
new copy.
Depending on the attachment, install the necessary front guard to the machine.
Depending on the attachment, the impact noise may make it difficult for fellow workers to transmit
instructions for the operation. Before starting operation, decide a leader and determine the signals to
be used.
Do not carry out swinging operations to the side with a heavy load on the attachment. This is particu-
larly dangerous on slopes.
Compared with a machine equipped with a bucket, a machine equipped with a breaker has a heavy
load at the front of the work equipment and is unstable. To avoid the danger of tipping over, do not
carry out operations with the attachment swung to the side.
When an attachment is installed, the swing range and center of gravity of the machine are different,
and the machine may move in an unexpected way. Be sure that you understand the condition of the
machine properly.
Before starting operations, set up a fence around the machine to prevent people from entering.
Never operate the machine when there are people near the machine.
To prevent serious accidents caused by misoperation, do not put your foot on the pedal except when
operating the pedal.
Precautions for removal and installation operations
When removing or installing the attachment always do as follows to ensure safety in the operation.
Carry out the removal and installation operation on firm, level ground.
When carrying out the operation with two or more workers, determine the signals and follow these
during the operation.
Always use a crane when you lift or carrying heavy objects (more than 25 kg (55.1 lb)).
When removing heavy components, always support the component before removing it.
When lifting with a crane, be particularly careful about the position of the center of gravity.
It is dangerous to carry out operations with a load left raised by a crane. Always prepare a stand and
ensure that the condition is safe.
When leaving an attachment removed or when installing the attachment, make sure that it is in a sta-
ble condition and cannot fall over.
Never go under a load raised by a crane.
Stay in a safe place where there is no danger if the load should fall.
NOTICE
Qualifications are required to operate a crane. Never allow the crane to be operated by an unqualified per-
son.
For details of removal and installation operations, contact your Komatsu distributor.
