Operating elements:
The M&K Basis offers the following setting options:
– The operating pressure control for the pressure vessel via the pressure
reduction valve (Fig. 20, item 4); manometer display (Fig. 20, item 6)
– Setting of the oil quantity in the capillary hose via the oil quantity control
(Fig. 20, item 7)
– Setting of the secondary air quantity via the throttle valve screw mounted
on the side (Fig. 20, item 3)
Filling:
The M&K Basis must be refilled when the "Minimum" marking in the filling
level display (Fig. 20, item 5) is reached.
The minimal lubrication system may be filled only in the pressure-free state.
To do this, interrupt the air supply (Fig. 20, item 1) that supplies the minimal
lubrication system. This bleeds the device automatically ("NULL" manometer
display). If the device is pressure-free, the oil filling screw (Fig. 20, item 9)
can be removed and the medium filled. Whereby, to prevent functional prob-
lems, the "Maximum" marking should not be exceeded. After filling, the
screw plug should be inserted and fastened tightly again.
Fast flooding the supply line (for the initial commissioning)
As delivered, the capillary hoses of the coaxial lines are not filled with oil. To
quickly fill the often metre-long oil lines located within the coaxial line, the
