WARNING
The gas spring is charged with high-pressure nitrogen gas, so mistaken operation may cause an explo-
sion, which will lead to serious injury or damage. When handling the gas spring, always do as follows.
Do not disassemble the accumulator.
Do not bring it near flame or dispose of it in fire.
Do not make holes in it or weld it.
Do not hit it, roll it, or subject it to any impact.
When disposing of the accumulator, the gas must be released. Please contact your Komatsu distributor to
have this work carried out.
The gas springs are located at the cab roof (left, right: two places).
