SAFETY
WARNING: Failure to follow these safety precautions may lead to a serious accident.
For work in mines, quarries, demolition, tunnels or other
●
places where there is danger of falling rocks, put FOPS (fall-
ing object protective structure) in place. Also, place a lami-
nate coating sheet over the windshield.
The above comments are made with regards to typical working
conditions. By all means you should put on other guards if
required by conditions at your particular site.
For details of safety guards, please contact your Komatsu distrib-
utor.
Also, even for other types of work, if there is any danger of being
hit by falling or flying objects or of objects entering the operator's
cab, select and install a guard that matches the working condi-
tions.

Be sure to close the front window before commencing work.
When carrying out the above operations, make sure to keep all
persons other than the operator outside the range of falling or fly-
ing objects. Be particularly sure to maintain a proper distance
when carrying out shear operations.
PRECAUTIONS FOR ATTACHMENTS
When installing and using an optional attachment, read the
●
instruction manual for the attachment and the information
related to attachments in this manual.
Do not use attachments that are not authorised by Komatsu
●
or your Komatsu distributor. Use of unauthorised attachments
could create a safety problem and adversely affect the proper
operation and useful life of the machine.
Any injuries, accidents, product failures resulting from the use
●
of unauthorised attachments will not be the responsibility of
Komatsu.
MACHINES WITH ACCUMULATOR
On machines equipped with an accumulator, for a short time after
the engine is stopped, the work equipment will lower under its
own weight when the work equipment control lever is shifted to
LOWER. After the engine is stopped, raise safety lock lever to the
LOCK position.
When releasing the pressure inside the work equipment circuit on
machines equipped with an accumulator, follow the procedure
given in the inspection and maintenance section.
Method of releasing pressure, see "HANDLING ACCUMU-
LATORS (144)"
The accumulator is filled with high-pressure nitrogen gas, and it is
extremely dangerous if it is handled in the wrong way. Always
observe the following precautions.
