To replace the hydraulic cylinder for the longitudinal shifting, first take off the table top as stated in
Chapter III
“Removing The Table Top“.
Then remove the crusting protector and loosen the expansion bellows. For further information please see
Chapter IV „Removing The Crusting protector“, Chapter V“ Removing The Column Cover“
and
Chapter
VI “Loosening The Expansion Bellows“.
Do as follows:
Loosen the threaded joint at the end of the hydraulic cylinder.
Note:
While loosening the screw, the piston has to be supported
with a - e.g.- screwdriver in order to disconnect the threaded
joint.
Now remove the fastening screws of one of the two guide
rails of the hydraulic cylinder block.
As soon as the guide rails are taken off the cylinder block can
be removed.
In case the hydraulic cylinder is faulty it now can be replaced
by removing the screws of the tube connection.
After removing the screws, the tube can be easily removed
from the block.
Attention:
Should the cylinders or the tubes still be pressurised, oil
might penetrate.
We recommend to have a collecting pan for waste oil at
hand.
