7.2 RESIDUAL FILM REMOVAL AND MISCELLANEOUS
Before removing any film residues and impurities deposited on the hot parts of the
machine wait until the machine has cooled down
For the cleaning of the lower bell, remove the netting and the larger residues, then go over using
a vacuum cleaner.
7.3 GENERAL CLEANING
Use exclusively a damp cloth to clean the bell. Do not use any detergents or solvents,
since these could damage its transparency.
Clean the machine more frequently if it is used in dusty environments and, in particular, suck
away any dust being deposited on internal electrical components, by removing the machine
back cover.
