STEP 11:
To install a new roller or replace the original roller, reverse the removal procedure. Be sure to properly reposition
the sprockets and align the chain. All three sprockets should be in line with each other. Since the motor sprocket
was not removed, use it as a guide for alignment of the pull roll and laminating roll sprockets.
NOTE: See page 24 for additional information on a sproket alignment & tightening.
• The pull rollers on this laminator are interchangeable
with the laminating rollers. If the laminating rollers have
minor damage, each can be replaced by pull rollers. If
the laminating rollers are too badly damaged, they must
be replaced. The condition of the laminating rollers is
very important for a good lamination.
• If the chain feels too loose, it may be tightened as follows:
Loosen the motor mounting screws. Push down on the
motor sprocket and refasten the motor mounting screws.

NOTE: Be sure to adjust the pressure on both pressure adjusting screws. 2-3 threads should show through the
adjusting screw mounting bracket. See page 21.
