The gas spring is charged with high-pressure nitrogen gas, so improper handling may cause an explo-
sion resulting in serious personal injury or death. When handling, always observe the following.

and at the cab ceiling window (2 places).
In the following cases, ask your Komatsu distributor for inspec-
tion, repair, and replacement.

window cannot be opened lightly.
