Step 3:
• Thread the top roll of film under the idler roller.
Pull the film down so that the film's lead edge is
below the lower heat shoe.
• Next thread the bottom roll of film under the
lower idler bar pulling film upward until it is even
with the top heat shoe and parallel side to side
with the top roll of film.
"Tack" it to the top film edge, this creates a film "Web".
NOTE: Use caution when threading film around heat shoes.

Step 4:
• Loosen tension on both rolls of laminating film.
Rotate both roller lifts to their full clockwise position.
Be sure that the slitters are rotated up and out
of the film's path.
Turn on the "Drive" switch and using the threading
board–push the film web into the laminating rolls.
This process will push the web into the pull rolls
and exit. Take extra care to ensure that the film exits
between the rear rollers. Your laminator is now loaded.
NOTE: Slowly run the laminator while threading to
help maintain control.
•
Remove the threading board and
save for your next use.
NOTE: Create your own threading board from a
piece of poster board 12" x 25".
