Chapter 7. Ordinary maintenance

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 and take out any pieces that may have fallen inside (figure 7.3.A page 69).
When the roll of the automatic coiler (29) is full, remove the film by unscrewing the knob (30) and taking away the disk
(31) (figure 7.3.B page 69) (where expected).

7.4. Machine cleaning

To clean the upper hood (19), clean both the outer and the inner side with water and soap only
(figure 7.4. page 70).
Do not use any detergents with solvents which could damage the upper hood (19) and reduce the
transparency.
!
Use a cloth moistened with water for the cleaning of the machine.
!
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.

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 70). 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 70):
1. Disconnect power to the machine
2. Unscrew the 2 screws (32) and remove the cover (20)
3. Unscrew the screw (21) intended to lock the sealing blade in the piston (22)
4. Remove the terminal (23) so as to extract the sealing blade from the piston (22)
5. Repeat the operations described by point 2-3-4 also for the rear piston
6. Unscrew the screw (25)
7. Remove the old sealing blade
8. Clean the housing and if necessary replace the insulating teflon (24) of the central clamp
9. Insert the new sealing blade starting from the central clamp and tighten the screw (25)
10. Trim the new sealing blade according to the holes of the pistons (22)
11. Complete the insertion if the sealing blade in the whole housing
12. Push the front piston (22) completely onwards towards the sealing blade to make it enter the hole of the piston itself
and then tighten screw (21)
13. Repeat the operations described by point 12, also for the rear piston
14. Trim the teflon projecting from the central clamp
15. Make sure that the sealing blade is well positioned and in tension
