Checking the setting:
3-6
With the machine running (typical operating status) 0.2 to
max. 1 drops/min. or 0.5 to 5 drops/1000 l air.
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
•
lubricator setting twice a week.
1. Ascertain the actuator which is furthest from the lubricator.
2. Ascertain the valve terminal which controls this cylinder.
3. Remove the silencer, if fitted, from port (3/5).
4. Hold a piece of white cardboard 10 cm in front of the
exhaust port.
5. Let the system run for a short period.
– There must be only a slight yellow colouring on the
cardboard. If oil droplets appear, this is an indication
that too much oil has been used.
Another indicator of over-lubrication is the coloration or the
condition of the exhaust air silencer. A distinctly yellow
colouring of the filter element or drops of oil on the silencer
indicate that the lubricator setting is too high.
