Before replacing the hydraulic cylinder for the transverse shifting function, remove the table top. For further
help, please see
Chapter III “Removing the Table Top“.
Also remove the crusting protector and loosen the expansion bellows, as stated in
Chapter IV “Removing the
Crusting protector“, Chapter V “Removing the Column Cover“
and
Chapter VI „ Loosening the expan-
sion bellows“.
Do as follows:
In order to approach to the cylinder block of the transverse
shifting function, the upper base plate has to be dismantled.
First loosen the connection between the cylinder block and
the upper base plate by loosening the two screws of the
connection of the cylinder from underneath the upper base
plate.
The connection is placed on the left.
Now the upper base plate is freely movable by hand.
Attention:
Take care as not to pull the base plate with its rails out of
the guide rails. That would destroy the guide rail system
and render it useless!
Move the base plate by hand to the left side until you will be
able to reach the screws, which connect the guide rails to
upper base plate, from underneath. (3x screws/ rails).
As soon as this procedure is carried out, do the same on the
opposite side.
Attention:
Before removing the last screw, a second person should
secure the base plate, as it is no longer connected to the
frame and therefore prevent it from falling down.
When all fastening screws are removed, the upper base plate
can be detached from the frame.
Note:
There are still connections, e.g. cables and hydraulic tubes
attached to base plate.
Put the plate on a place of deposit, prepared in advance and
in the same height as the table frame.i
Attention:
While removing the base plate do not damage any
electrical wires or tubes!
