Lift up the fast adjusting ring (2) and push the turning
chisel (1) through until the centring roller lies against the
side wall (arrow) of the liner collar.
Bring the toggle switch (3) to middle position (middle
position "0"). This results in residual magnetic force in
the magnetic ring which holds the machine lightly on the
sealing surface.
Note
During any subsequent work, the advance nut (5) must
not move when the driving crank is being turned,
otherwise the depth setting of the turning chisel is
altered. If necessary, the stud screw (6) in the advance
nut (5) must be tightened.
Turn driving crank clockwise and check that the
centring roller runs along the entire circumference
and the machine does not shift (with toggle switch in
middle position). If the machine shifts, turn over the
driving crank clockwise while holding the face feed ring
(7) firmly in place. If the centring roller loses contact
with the collar edge, the driving crank must be turned
over counterclockwise (while the face feed ring (7) is
held firmly), until the roller makes contact around the
entire circumference.
Note
Centring is correct when the centring roller has even
contact all the way around and the machine remains
securely in place when in position "0".
