Maintenance and Troubleshooting

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

•3/16" hex wrench

•Screwdriver

To adjust the chain tension:

WARNING

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.

1.Remove the drive side cabinet cover using the 1/8" 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 3/16" hex wrench as shown in the figure below. The motor should just move freely within the slots.
