3.5. Preparing the air (for machine with air motor)
Connect the machine to a correctly prepared air source of sufficient purity. Make sure
that all inner diameters of the air source (including the supply hose and fittings) are of
at least 10 mm (0.4
″). Make sure that the air source has an air preparation unit that
contains a filter, regulator, and lubricator (FRL).
Maintain the FRL unit as required. Keep the water trap drained, filter cleaned,
and the lubricator oil reservoir filled so that there is a drop of oil every 2
–5 seconds.
Use oil whose ignition temperature is more than 260°C (500°F). If you are not going
to use the machine for at least 24 hours, increase the supply of oil and let the motor
operate for 2
–3 seconds. This will prevent rusting and degrading of the rotor vanes.
