The Roller Pressure Handle adjusts the amount of
roller pressure needed for various laminating and
mounting applications. Pull the handle away from the
laminator, rotate it to the desired pressure, and press
it into the desired slot. Three main function settings
are provided.
IMPORTANT: Use a pressure setting that is
appropriate for the material you are laminating or
mounting.
Release – Provides the widest opening of 1/2 in. (1.6
to 12.7 mm) between the pressure rollers and takes
pressure off the rollers. This is used when installing
new rolls of film. When the machine is not in use, put
the handle in this position.
Mounting – Used when bonding to a rigid substrate
such as mounting boards. Thickness range is 1/16 to
1/2 in. (1.6 to 12.7 mm).
Laminating – Used to adhere materials in multiple
substrates. The two positions are low (right) and high
(left) pressure.
