Chapter 7. Ordinary maintenance
7.5. Substituting the rubber and Teflon
When the Teflon-strikers (32) are worn out, substitute them
with spare parts, making sure the application is linear and
even.
Before applying the Teflon self-adhesive strip clean the
rubber part (33) with a detergent.
If the rubber (33) is also damaged, substitute it as follows:
Remove the old rubber
Clean its housing
Insert the new rubber in a linear way
Clean the rubber with a detergent
Apply the self-adhesive Teflon-strip.
7.6. Changing the sealing blade
To replace the sealing blade (13) follow this procedure:
1.
Disconnect power to the machine
2.
Unscrew the 2 screws (V1) and remove the cover (21)
3.
Unscrew the screw (V2) 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 (V3)
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 (V3)
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 (V2)
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.
