Take the cover plugs out of the ends of the handles and
unscrew them with an allen key. (pos. 1).
Remove the plastic cover (pos.2).
Lift the upper ram and remove the lock washer (pos.3).
Pull out the upper ram. Do not remove the rod (pos. 4) 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 there is any friction in the threads, they should be
lubricated with a dry lubricant such as MoS
2
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.

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.
