Procedure
All oils eventually shear or thin out with use, reducing their lubricating ability.
In addition, heat, oxidation, and contamination may cause the formation of
sludge, gum, or varnish in the system. For these reasons, it is important to
change the hydraulic oil at specified intervals. For further information,
