WARNING
The accumulator is charged with high-pressure nitrogen gas, and improper operation may cause an ex-
plosion which will lead to serious injury or death. When handling, always observe the following.
• The pressure in the hydraulic circuit cannot be completely removed. When removing the hydraulic
equipment, do not stand in the direction that the oil spurts out when performing the operation. In
addition, loosen the bolts slowly when performing the work.
• Do not disassemble.
• Do not bring open flame close to it or do not dispose of it in fire.
• Do not perform drilling, welding or flame-cutting.
• Do not hit or roll it, or subject it to any impact.
• When disposing of it, the gas must be released. Ask your Komatsu distributor to have this work per-
formed.
