English to Polish Tech/Engineering Engineering (general)

Jest to instrukcja obsługi układów hydraulicznych (tłumaczona z jęz. niemieckiego na angielski - niestety nie posiadam dostępu do wersji oryginalnej).

The PRESSURE FLUID level is not constant when the hydraulic system is in operation.
The level changes result from:
- the differing volume requirements of cylinders or the loading/unloading of accumulators with PRESSURE FLUID during the work cycle
- leakage losses.

Due to the above mentioned reasons, it has to be determined by visually monitoring the fluid level over a complete machine working cycle if and how much PRESSURE FLUID has to be refilled.
