PTFE Adjustment
An anti-stick sheet which prevents the bag from sticking to heater bar surfaces is located
immediately behind the front plate. The sheet should periodically be inspected for wear or
damage. If holes or tears exist, the rolls can be turned (rotated) to cover the contact surfaces with
fresh material.
If a change of material is required, turn the main power to the OFF position and unplug the
power cord. Lower the inner frame by pulling the handle downward. The rollers are located on
the outside lower frame, on the left and right side of the inner frame which extends beneath the
side-plates (Fig. 4-17).
To adjust the material, turn the lower roller clockwise approximately 1/4 turn using a flat-head
screw-driver. When fresh material is in place, turn the roller counterclockwise releasing ALL of
the tension on the sheet.
CAUTION: If sheet tension is not released, the material will tear when the seal bar engages.

PTFE Replacement
Turn the power to the OFF position and unplug the power cord. Remove the four screws which
hold the front plate to the inner frame. Pull the front plate from the inner frame and slide the front
plate along the guide rods away from the seal assembly.
Then slide the rollers and the roller holder away from the heater bar as a unit. Remove and discard
the anti-stick sheet. Replace the sheet and rollers with the new material wrapped on the upper
roller. Place the rollers on the roller holder, ensuring springs are seated in the grooves on the
rollers. Replace the rollers and holder as an assembly (with the unexpended material on the
upper roller). Replace the front plate and retighten the four screws. Adjust the sheet as described
in section 4.12.
Note: Fiber spacers are located behind the front gripper plate which may fall when removing the
front plate screws.
