What the ministry says is wrong
ショベル・ローダ等の駐車ブレーキにおいて、組付け作業が不適切なため、シリンダーピストンシールを逆向きに組付けたものがある。そのため、そのまま使用を続けると、駐車ブレーキシリンダーから油漏れが発生し、警告灯が点灯するおそれがある。What is to be done about it
全車両、駐車ブレーキシリンダーを良品に交換する。The two passages above are quoted in Japanese because that is the language the ministry published them in. This site keeps the wording a register had when it was read, and does not translate a safety notice.

Reading this against the source
This page is what MLIT published in the recall notices it publishes, kept as it was read. The authority publishes only its current wording; if a notice is rewritten, the earlier version disappears there and is kept here. The whole register is at /japan, and how the reading is done is set out in the method.
This register keeps an index of its own for every maker and every year it holds: Japanese recalls on a Komatsu: 297 in the register, and 201 Japanese vehicle recall notifications filed in 2026.
