自動注油器

部分車輛 配有自動注油器，為部分必須潤滑 的機構進行潤滑。其上有兩個視窗，左側顯示車輛儲有的滑油存量，右側顯示透過此設備潤滑的傳動系統 軸承油位。

When the vehicle is in motion, oil in the bearings will be spent. However, the automatic lubricator automatically replenishes it from the onboard storage.

If the vehicle has been parked and the bearings have run dry, however, the lubricator must be manually primed by turning a crank on it, until the bearings are full, before the vehicle can be set in motion again.
