Film Tension - usi ARL 4000 Owner's Manual

 When setting the heat to a temperature below 200˚F, first rotate the Heat Control Knob
fully clockwise and then proceed to the desired temperature setting.
 The temperature display can be toggled between Fahrenheit and Centigrade by
depressing the C/F button on the Display Board.

Film Tension...

To adjust the film tension on the Top and Bottom Supply Mandrels, the laminator must be
loaded and heated. Remove the Heat Guard and Feed Table and then loosen the tension on
both rolls of laminating film by turning the Tension Adjustment Knobs counter-clockwise until
there is no drag on either the Top or Bottom Supply Mandrels. Turn the Speed Control Knob to
a slow speed setting and set the Motor Drive Switch to the "FORWARD" position. As the film
runs through the laminator it will appear wrinkled and bubbly. Gradually increase the tension
on both the Top and Bottom Supply Mandrels by turning the knobs clockwise until the film is
smooth on the Heat Shoes and is no longer wrinkled and bubbly appearing.
Notes:
 For best results, reset the film tension with EACH new set of film rolls
 As the film supply becomes low and the roll diameter decreases, it is necessary to
decrease the tension on the film rolls.
 Too little tension on the Top or Bottom Supply Mandrels causes vertical or diagonal
streaks in the film as it passes over the Heat Shoes.
 Excessive tension will lead to increased wear and tear on the laminator and will cause
exiting laminating film to curl excessively.
Cleaning the Machine...
If you service the laminator yourself, call USI Technical Assistance (800-752-9131) for additional
service and safety recommendations.
Cleaning the Heat Shoes
With continuous use, the Heat Shoes will accumulate adhesive and dirt. It is recommended
that you periodically inspect them and clean them. Use USI's Laminator Cleaning Kit which
contains cleaning fluid, a Scotch Brite® scrubbing pad for Rubber Rollers and a mesh covered
sponge for Heat Shoes.
