¤ WARNING: Failure to follow these safety precautions may lead to a serious accident. 6. GENERAL PRECAUTIONS 1-9 PRECAUTIONS FOR ATTACHMENTS ‡ When installing and using optional parts or attachments, read the instruction manual for the attachment and the information related to attachments in this manual. ‡ Do not use attachments that are not authorized by Komatsu or your Komatsu distributor. Use of unauthorized attachments could create a safety problem and adversely affect the proper operation and useful life of the machine. ‡ Any injury, accidents, or product failures resulting from the use of unauthorized attachments will not be the responsibility of Komatsu.
ACCUMULATOR ‡ When leaving the machine, lower the work equipment (including any attachment) completely to the ground, set safety lock lever 1 to the LOCK position, and lock attachment control pedal with lock pin. ‡ When releasing the pressure from the control circuit of machines equipped with an accumulator, or when releasing the pressure of the charge gas, carry out the operation according to the instructions in the instruction manual for the accumulator. See METHOD OF RELEASING PRESSURE, CHARGING GAS, 11.19 HANDLING ACCUMULATOR. ‡ The accumulator is charged with high-pressure nitrogen gas, so it is extremely dangerous if it is handled mistakenly. Always observe the following precautions.
• Do not make any hole in the accumulator or bring any flame close. • Do not weld any boss to the accumulator. • When scrapping the accumulator, the charged gas must be released, so please contact your Komatsu distributor. INDOOR VENTILATION ‡ When starting the engine, or using fuel, flushing oil, or paint indoors or in areas with poor ventilation, always open the windows and doors to improve the ventilation and prevent the danger of gas poisoning. ‡ If the ventilation is still insufficient even when the windows and doors are opened, use a ventilation fan.
A0055060 CAB GLASS ‡ If the cab glass on the work equipment side should be broken, there is serious danger that you may come into direct contact with the work equipment. If the glass breaks, stop operations immediately and replace the glass.
