Smaller chain tensioning adjustments on the F-60 Lam-
inator are handled by a secondary chain tensioner, how-
ever, when installing a new chain or when the chain
tension is more seriously out of adjustment, use the fol-
lowing procedure to adjust the chain tension.
Tools required:
•
1

8
" hex wrench
•

• Screwdriver
To adjust the chain tension:
WARNING
1. Remove the drive side cabinet cover using the

hex wrench by removing the eight screws holding
the cover in place. Gently rotate the cover around
the clutch knob to allow access to the drive system
(chain).
2. Loosen the secondary chain tensioner on the sec-
ondary drive chain. The tensioner should, at this
point, not be engaging its respective chain.
3. Loosen all four motor mount bolts using the
3

hex wrench as shown in the figure below. The
motor should just move freely within the slots.

4. Using a screwdriver, apply a small amount of
downward pressure on the motor by prying against
the inside of the side frame until there is ¼" to ½"
play in the chain.
5. Tighten the mounting bolts while maintaining the
downward pressure on the motor.
6. Engage the secondary chain tensioner and apply
pressure until its chain exhibits similar tension to
the primary chain tension.
7. Replace the cabinet cover and reapply power to the
laminator.
Remove and lockout power from the laminator
while you are performing this procedure. You
could be severely shocked, electrocuted, or get
your fingers caught in the drive mechanisms.
