MAINTENANCE MAINTENANCE
Step 1.
Remove the seal bars from the machine. Pull
off the Teflon
®
tape strip and discard. Clean
off any remaining Teflon
®
tape adhesive
using acetone or an equivalent solvent.
Step 2.
Using a 2mm Allen wrench, loosen the set
screws for the cut-off wire and the seal
element on both ends of the seal bar and
discard.
Step 3.
If you are replacing the L-shaped spring retainer and the spring at this time, loosen the set
screw and remove the old spring retainer and spring and install the new ones. Adjust the
spring retainer to allow an 1/8-in. gap between the spring retainer and the seal bar. This
will allow the seal element to remain under tension after tightening the seal element.
