6. GENERAL PRECAUTIONS WARNING: For reasons of safety, always follow these safety precautions. 1-6 PRECAUTIONS WHEN USING ROPS If ROPS is installed, do not operate the machine with the ROPS removed. The ROPS is installed to protect the operator if the machine should roll over. It is designed not only to support the load if the machine should roll over, but also to absorb the impact energy. ‡ The Komatsu ROPS fulfills all worldwide regulations and standards, but it is damaged by falling objects or by rolling over, its strength will be reduced and it will not be able to fulfill its function properly. In such a case, please contact your Komatsu distributor for advice on the method of repair.
Even if ROPS is installed, it can only provide proper protection if the operator wears the seat belt. Always fasten the seat belt when operating the machine. Seat belt © See “12.1.3 ADJUSTMENT BEFORE OPERATION”. 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 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 injuries, accidents, product failures resulting from the use of unauthorized attachments will not be the responsibility of Komatsu. PRECAUTIONS WHEN HANDLING ACCUMULATOR ‡ If the travel damper switch is turned ON when the machine is traveling or when the work equipment is raised, the hydraulic accumulator in the travel damper will instantaneously be connected with the lift cylinder bottom circuit. Be careful when doing this, because the oil will then flow in or out in the direction to balance the oil pressure at the accumulator and lift cylinder bottom, so the work equipment will move.
‡ When releasing the pressure or charging with gas for the work equipment circuit of machines equipped with an accumulator, be careful to follow the instructions given for handling the accumulator. ‡ The accumulator is charged with high-pressure nitrogen gas, which is extremely dangerous, so read the following items and be careful to handle the accumulator properly. ‡ Do not make any hole or bring any flame or heat close to the accumulator. ‡ Do not weld any boss to the accumulator. ‡ The gas must be released before disposing of the accumulator, so please ask your Komatsu distributor to do this.
VENTILATION FOR ENCLOSED AREAS ‡ If it is necessary to start the engine or if you handle fuel, flushing oil, or paint within an enclosed area or poorly venti- lated area, open the doors and windows to ensure that you provide adequate ventilation to prevent gas poisoning. ‡ If opening the doors and windows still does not provide ad- equate ventilation, set up fans.
