Caution
Operation with lubricated compressed air will cause the
service life lubrication, which is necessary for non−lubri
cated operation, to be "washed out."
Please note the following instructions if lubricated com
pressed air must be used.
The compressed air prepared with the compressor must
correspond in quality to non−lubricated compressed air. If
possible, do not operate the complete system with lubricated
compressed air. If possible, always install the lubricators di
rectly in front of the consuming actuator.
Caution
Incorrect additional oil and too much residual oil content in
the compressed air will reduce the service life of the valve
terminal.
Use Festo special oil OFSW−32 or the other oils listed in
the Festo catalogue (as per DIN 51524−HLP32, basic
viscosity 32cST at 40 °C).
The additional lubrication must not exceed 25 mg/m
3
(ISO 8573−1 class 5).
Make sure that the lubricator setting is correct (see fol
lowing section)
You will thereby avoid functional damage to the valves.
Setting the lubricator: with the machine running (typical operating status) 0.2 to
max. 1 drop/min. or 0.5 to 5 drops/1000 l air.
Checking the setting: the procedure described below can be used for checking the
setting of the lubricator.
Proceed as follows:
·
Check the service units in respect of condensate and lu
bricator setting twice a week.
1. Ascertain the cylinder which is furthest from the lubrica
tor.
