WARNING: Failure to follow these safety precautions
may lead to a serious accident.
PRECAUTION 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 follow
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 boss to the accumulator.
!
The gas must be released before disposing of the accumulator, ask your Komatsu distributor to do this.
