Take the cover plugs out of the ends of the handles.
Unscrew the two handles with an Allen key (pos. ).
Remove the plastic cover (pos. ).
Lift the upper ram and remove the lock washer (pos. ).
Pull out the upper ram. Do not remove the rod (pos. ) from
the upper ram unless absolutely necessary.
If it is necessary to remove the rod, hold the upper ram in a
vice or a similar device. The ram surface
must be protected
with plastic or soft metal.
In case of a slight friction in the threads, the lubrication should be
carried out using a dry lubricant such as MoS

Lubricant Powder
or graphite.
When using cooling water from the mains tap in areas with a high
chalk or mineral content, deposits can build up in the cooling coil.
This may reduce the cooling effect, so once a year the cooling coil
should be decalcified.
Remove the mounting unit. (See this section.)
Flush the coil with a mild decalcifying fluid, such as that used
for coffee machines.
Flush the cooling coil with clean water.
Re-install the mounting unit.
Only relevant when a Recirculation Cooling Unit is connected:
Important
Do not polish the surface on the sides of the rams. If the sides of the rams
are heavily scratched, they must be scrapped. If the top closure has been
dropped, causing a dent or deformation in the edge of the upper ram, the
ram must also be scrapped.

Lubricating the Threads of the
Top Closure
Important
Please observe that the threads in the joint between the top closure and the
mounting cylinder must not be lubricated with oil or grease. As the mounting
cylinder operates at high temperatures, only a dry lubricant, resistant to high
temperatures, can be used.
