What the notice says ロード・ローラにおいて、 （１）牽引時に使用するアンロードバルブの設計評価が不適切なため、走行時の油圧負荷がかかることにより、バルブ内のボールシートが変形することがある。そのため、そのままの状態で使用を続けると、ボールの固定力が小さくなり、走行時の振動等によりバルブのレバーが意図せず動き、最悪の場合、走行中、アンロードバルブが全開になり、走行モータに油圧がかからずに走行不能となるおそれがある。

What the ministry says is wrong
ロード・ローラにおいて、 （１）牽引時に使用するアンロードバルブの設計評価が不適切なため、走行時の油圧負荷がかかることにより、バルブ内のボールシートが変形することがある。そのため、そのままの状態で使用を続けると、ボールの固定力が小さくなり、走行時の振動等によりバルブのレバーが意図せず動き、最悪の場合、走行中、アンロードバルブが全開になり、走行モータに油圧がかからずに走行不能となるおそれがある。What is to be done about it
全車両、 （１）アンロードバルブを対策品に交換する。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 Hitachi: 96 in the register, and 438 Japanese vehicle recall notifications filed in 2015.
