GENERAL PRECAUTIONS SAFETY WARNING: For reasons of safety, always follow these safety precautions.. 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. (B) (C) Be sure to close the front window before commencing work. AB30052C 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, set the PPC lock switch to the off position (and also lock the attachment pedal with the lock pin). 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 THE ACCUMULATOR” on page 103. 22 (B): Top guard (C): Front guard (I)
