•
A breather and filler cap provides an opening for adding oil.
It also allows filtered air to enter the space above the oil as
the oil level goes down and allows air to leave as the oil level
goes up. It maintains constant atmospheric pressure above
the oil.
•
A sight-glass provides a direct visual indication of oil level
without opening up the reservoir.

6.4.5 Additional Recommended Features
The following features are not essential, but are recommended as
measures which will help to maximize hydraulic system reliability,
efficiency and life.
•
Magnetic drain plug(s) trap ferrous particles and should
be easily accessed for cleaning.
•
A temperature gauge, either separate or built into the
sight-glass, allows operator to read reservoir oil
temperature.
•
A strainer in the filler neck keeps large contaminants out
of the reservoir during oil addition.
•
A return line flow diffuser mounts to end of return line
drop tube and reduces the oil velocity before the oil
emerges into the main interior volume of the reservoir;
