6.1 Storage
If the machine is not used for a longer period of time,
it has to be carefully cleaned. Spray bright metal parts
with a rust inhibitor.
Store the machine only in dry rooms and protect it
from the effects of weather.
6.2 Tools
The milling heads used on the machine should be
regularly deresinified, as clean tools improve the
cutting quality.
Deresinify them by placing them in petroleum or a
commercially available deresinification agent for 24
hours.
Aluminium tools may only be
deresinified with solvents which do
not corrode the aluminium.
Promptly replace damaged clamping screws and
cutting elements.
The design of progressive tools must not be modified
during maintenance.
