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
lubricator setting twice a week.
1. Ascertain the cylinder which is furthest from the
lubricator.
2. Ascertain the valve terminal which controls this cylinder.
3. Remove the silencer, if fitted, from connection 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 drops out, 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 col
ouring of the filter element or drops of oil on the silencer indi
cate that the lubricator setting is too high.
