Chapter 7. Ordinary maintenance

7.2. Sealing blade cleaning

!
Using a dry cloth, wipe off the residues clinging to the sealing blade: do this at once after sealing since they are
easier to remove when still warm.
!
Periodically lubrificate the sealing blade with the grease supplied with the machine (figure 7.2. page 60).

7.3. Plastic film and other scrap removal

Wait for the machine to cool down completely before removing any scraps stuck to the hot parts of the machine (e.g., on
the flaps of the heat chamber). If the lower cover requires cleaning (where the fan is installed), remove the reticulated
plate (11) and take out any pieces that may have fallen inside (figure 7.3. page 60).

7.4. Machine cleaning

!
Use a cloth moistened with water for the cleaning of the machine (figure 7.4. page 61).
!
For cleaning the upper hood (19) inside and outside we recommend to use a normal detergent for glass cleaning.
Do not use any detergents with solvents which could damage the upper hood (19) and reduce the
transparency.
!
If the machine works in a dusty environment it is necessary to clean it more frequently inside as well as outside. It is
especially recommended to vacuum-clean the dust which settles on the interior electrical components. To open the
switch box again remove the 4 fastening screws.

7.5. Rubber and teflon replacement

When the Teflon-strikers (17) are worn out, replace them with spare parts, paying attention that the application is linear
and even (figure 7.5. page 61). Before applying the Teflon self-adhesive strip clean the rubber part (18) with a detergent.
If also the rubber (18) is damaged, replace it as follows:
1. remove the old rubber
2. clean its housing
3. apply some drops of glue in the housing
4. insert the new rubber in a linear way
5. clean the rubber with a detergent
6. apply the self-adhesive Teflon-strip.

7.6. Changing the sealing blade

To replace the sealing blade (13) follow this procedure (figure 7.6. page 61):
!
Disconnect power to the machine
!
Unscrew the three screws (20), (21), (22)
!
Remove the old sealing blade
!
Clean the housing and if necessary replace the insulating teflon (23) of the central clamp
!
Insert the new sealing blade starting from the central clamp and tighten the screw (21)
!
Trim the new sealing blade according to the holes of the pistons (24) and (25)
!
Complete the insertion if the sealing blade in the whole housing
!
Push the rear piston completely onwards (25) towards the sealing blade to make it enter the hole of the piston itself
and then tighten screw (22)
!
Push the front piston (24) completely onwards towards the sealing blade to make it enter the hole of the piston itself
and then tighten screw (20)
!
Trim the teflon projecting from the central clamp
!
Make sure that the sealing blade is well positioned and in tension
