Element Ribbon: Remove the barrier tape as above. Place the loading pins through the
expansion blocks and holes in either end of the jaw to keep the springs under compression and
loosen the Allen key bolt. Remove the old ribbon. Cut a length of new element ribbon slightly
longer than the jaw and fold one end back on itself by about 5mm. Place this end in one of the
expansion blocks and tighten the Allen bolt. Measure the length of ribbon required to fit into
the other expansion block, cut to length and fold the end back 5mm. Fit in the other expansion
block and tighten the Allen bolt. Remove the loading pins and re-cover with barrier tape. Ensure
on double heat machines that the two elements line up to produce a good seal.

unscrewing the Allen bolt. Replace the brass shim, attach the brass clamp and re fit the ribbon
and tape as above.

ribbon and barrier tape as above.
