Breather filter/hydraulic oil filler neck
The breather filter is located on the hydraulic oil tank
(Fig. 154). It ensures the ventilation of the hydraulic oil
reservoir when the hydraulic oil level varies. The breather
filter contains a filter element that prevents dust and dirt
from entering and squirts of oil from escaping. The
breather filter contains a valve that keeps the pressure in
the reservoir at around 0.2 bar. This pressure escapes
when the hydraulic oil filler neck is opened.
Information
Replace the breather filter after 1000 operating hours!
