7.3 Replacing the PTFE belts
Warning! The heating blocks can still be hot, even if the sealer has
been switched off for a while.
Replace the PTFE belts as follows:
1. Put the cooling plate, the after-press
roller and the heating block in the
uppermost position.
Pull the lifting pin up and turn the
lifting plate in such a way that it
appears over the edge of the
protective cover.
2. Push the two tension rollers inward until
they are locked.
While pushing the tension roller
inward, the locking pin will fall into
a recess, preventing the tension
roller from springing back.
3. Remove the V belts by pushing these
from the pullies using a rotating move-
ment.
4. Remove the old PTFE belts and place
new ones.
Make sure no folds occur in the
PTFE belts. These may cause
breaking during use.
