11. EXPLANATION OF COMPONENTS 11.18 PRECAUTIONS WHEN HANDLING ACCUMULATOR WARNING 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. If any problem or failure occurs with the accumulator, please contact your Komatsu distributor immediately. The gas must be charged only by a serviceman from your Komatsu distributor or by a person licensed to handle high- pressure gas. Do not strike or bring any flame or heat close to the accumulator when it is charged with gas. Do not make any hole or weld any boss to the accumulator.
Always release the gas before disposing of the accumulator or disassembling it for maintenance. Use the air bleed valve to release the gas. Every 2000 hours or once a year, please contact your Komatsu distributor to have the gas pressure checked. The accumulator for the brake is installed on the side of the brake component box on the left side of the rear frame. The accumulator for the PPC valve is installed to the right inside under the center platform. When handling the accumulators, be extremely careful. 2-32
