PRECAUTIONS FOR ATTACHMENTS 0 When installing and using an optional attachment, read the instruction manual for the attachment and the information related to attachments in this manual. 0 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.
0 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 safety lock lever to the lock 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 90. 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. 20
