7.7 Replacing the Silicone Rubber of the Silicone Holders
To ensure a seal of good quality, the silicone rubber may not be damaged and the surface must be
smooth. Mechanical contact or burning by the sealing wire may damage the rubber.
Replace the silicone rubber if damaged or as specified in Maintenance Schedule on page 51.
Figure 21: Replacing the Silicone Rubber of the Silicone Holders
1.
Pull the old silicone rubber from the holder, see Figure 21: Replacing the Silicone Rubber of
the Silicone Holders on page 56.

If the rubber is too short or too long, this may cause problems with the seal of the
bag.
