WARNING: Failure to follow these safety precautions may lead to a serious accident. SAFETY The ROPS (Roll Over Protective Structure) must never be removed when operating the machine. 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 ROPS fulfills all the regulations and standards for all countries, but if it is rebuilt without authorization or is damaged when the machine rolls over, the strength may drop and not be able to fulfill its function properly. It can only display its performance if it is repaired or modified in the specified way.
When modifying or repairing the ROPS, always contact your Komatsu America International Company distributor. Even if the ROPS is installed, it cannot show its full effect if the operator does not fasten the seat belt properly. Always fasten the seat belt when operating. 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. Method of releasing the pressure or charging with gas 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 holes or bring any flame or heat close to the accumulator. Do not weld any bosses to the accumulator. The gas must be released before disposing of the accumulator, so please ask your distributor to do this.
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. Remove all dirt from the surface of the windows and lights to ensure that you can see well. Adjust the side mirror so that you can see clearly from the operators seat, and always keep the surface of the mirror clean. If any glass is broken, replace it with a new part. Check that the head lamps and working lamps light up properly.
