CM140 - Inspection of the pneumatic system
Orientation
Operating fluids such as hydraulic fluids, cooling lubricants, lubricating greases/oils
are also subject to degradation or aging as the components involved in this process,
and must therefore be serviced, refilled or replaced at regular intervals.
To ensure trouble-free operation, periodic checks of the pneumatic system are
necessary.
- Check pressure setting on pressure gauge.
- Check fluid lines.
- Check silencers.
- Drain off condensate.
- Check filters, replace if necessary.
Example: Pneumatic maintenance unit by Festo
a
Filter regulating valve (factory set to 6 bar)

.
d Branch module with pressure monitoring (factory set to min. 4.0 bar)
e High-precision pressure regulating valve (factory set to 0.3 bar)
f Pressure sensor
g Suction pump switching valve
h Throttle for fire protection sensor
( * ) Check by manually pushing (using a ballpoint pen or similar) the blue button of
the switch-on valve (manual auxiliary operation).
