and bottom rollers come into contact and the point
at which the items to be laminated are introduced to
the laminator.
The Upper Main Roller is heated. The •
temperature is controlled by the Control Panel.
The Upper Main Roller can be raised or

The Safety Photo Sensor prevents entanglement,
entrapment, and inadvertent contact with the
rollers. The sensors are located on each side of the
machine, in front of the bottom roller. They stop the
machine when a hand or object blocks the invisible
beam if you are not using the foot switch.
When the foot switch is used, the speed drops to 3
fpm (0.9 m).
WARNING: Keep your fingers and hands
away from the nip point. Failure to observe
this warning could result in severe personal injury.
