SAFETY PRECAUTIONS
WARNING: Please review the following safety precautions before unpacking your new laminator.
• Use care in unpacking and lifting the laminator. Keep laminator level when lifting or moving.
Larger models weigh 60 pounds or more.
• Consider work area. A cluttered work space can lead to accidents. The laminator should be placed on
a level sturdy surface. Do not attempt to operate the laminator in damp or wet environments. Do not
operate electrical devices in the presence of flammable liquids, solvents or in gaseous/explosive
atmospheres. Keep work area well lit. Allow sufficient access to front and back of machine. See the
manual for additional work space requirements.
• Respect feed rollers. Keep hands away from feed rollers and any other moving parts. Turn drive
switch OFF before attempting to clear film wrap-arounds or jams. Use reverse feature to clear film.
Do not wear any loose clothing, ties, jewelry, etc., which can be caught by feed rollers and draw any
body part into the machine.
• Respect heat shoes. Operating temperatures are hot enough to burn skin. If clearing a film wrap-
around or jam on or near heat shoes, first turn the heat switch OFF and allow laminator to cool to
room temperature. If your laminator is equipped with a heat shoe guard, do not operate without this
guard in place.
• Watch out for cutter blade at rear of laminator. Blade is extremely sharp.
• Do not operate laminator with any panels or guards removed. Panels and guards protect
operators from such moving parts as the drive chain and sprockets, roller ends, etc.
• Turn the drive switch OFF before walking away or leaving the laminator unattended.
• Before lifting or moving laminator, turn drive switch OFF, turn heat switch OFF, unplug unit and allow
to cool to room temperature. Remove film rolls before lifting or moving machine. Film is easy to
rethread, see the section in this manual.
• Keep children away. Make sure visitors are kept well back from an operating laminator.
• Do not abuse electrical cord. Never pull cord to disconnect it from a receptacle. Do not allow cord
to contact heat, oil or sharp edges. Do not cut off or otherwise bypass the grounding prong on the plug.
• If an extension cord is necessary be sure it is properly rated and of atleast the same wire gauge or smaller
as the laminator cord. Capacity of the cord must prevent loss of power and overheating. Before using,
inspect extension cord for any damage, including loose or exposed wires, broken fittings, damaged
insulation, etc.
• If you service the laminator yourself, call USI’s Technical Assistance department (1-800-752-9131)
for additional safety recommendations. Use only USI parts for service or replacement.
Failure to use USI parts could void manufacturer’s warranty. Note: Always turn laminator off and unplug
before servicing.
• Use common sense. Be cautious when operating your laminator. Do not operate laminator when
you are tired or your reactions are impaired in any way.
• Do not allow anyone to operate the laminator who has not received proper instruction and has not
read the safety instructions.

A separate work station is required to house your USI laminator. Ample room is necessary to access the
laminator from all 4 sides. If the laminator is back against a wall, the laminating film may back up and jam
the equipment. A USI laminator cabinet is an excellent choice for a work area. It can easily be moved and
provide sufficient storage for film in the cabinet below.
WARNING: Do not place the laminator where the heat shoes will be in the direct path of a room cool-
ing fan, air conditioner or similar forced draft.
Tools necessary to set up your laminator include cutting shears and any adhesive tape. For future service or
maintenance, an assortment of Allen wrenches, a flat head screwdriver and a Phillips head screwdriver are
necessary.

UNPACKING YOUR LAMINATOR
Photo 7-1
Photo 7-2
Your laminator comes packed in one carton. It
contains (1) laminator, (1) heat guard, (1) top
supply mandrel, (1) bottom supply mandrel,
(1) threading board, (1) feed table with guide,
(1) set of keys if equipped with a key lock, and
this operation and maintenance manual. (See
diagram page 5)
First, open the box. Using two people, carefully
lift the laminator from the carton by grasping
the side housings and lifting. Do not lift by the
upper idler bar or supply mandrel. These are
not weight bearing parts and can cause dam-
age to the machine.
For shipping purposes, white plastic tie straps
are used to hold the power cord, heat shoes,
and accessories in place. These straps are
approximately 1/8” wide and should be care-
fully cut and removed prior to set up.
Be sure to save the shipping carton…
Should your laminator ever need to be returned
for service, this carton ensures safe transit.
You new laminator comes pre-loaded and ready
to run. Install the feed table and heat guard as
shown on page 12. Plug the machine in and
turn the heat switch to the “on” position and
allow to heat for approximately 15 minutes.
After 15 minutes of heating time, set the Motor
Drive Switch to the “Forward” position and
allow the Rubber Rollers to rotate 1/2 turn. Set
the Motor Drive Switch to the “Off” position
and allow the machine to heat an additional 15
minutes before use. Check the heat setting and
adjust if necessary as shown on page 11.

LOADING FILM
COLOR-CODED LAMINATORS & FILM:
(For more information on this revolutionary system see the back cover)
Select the two rolls of laminating film that you wish to use. Both rolls of film should be of the same size, type and
thickness. Next, take the bottom supply mandrel (marked with the blue Color-Code) and insert it into the roll of film so
the blue end of the mandrel matches the blue end of the film roll. While inserting the mandrel, rotate it in the opposite
direction of which the “gripper dog” points while pressing into the roll of film and center on the mandrel. Place the
loaded mandrel on the machine by matching the blue end with the blue friction stud. To load the top, do the same as
the lower, only match the red ends.
FOR NON-COLOR-CODED LAMINATORS & FILM:
Select the two rolls of laminating film that you wish to use. Both rolls of film should be of the same size, type and
thickness. Next, take the bottom supply mandrel (labeled “Low”) and insert it into the roll of film until the “gripper dog”
meets the film’s cardboard core (photo 9-1). Rotate the mandrel in the opposite direction from which the “gripper dog”
points. As you rotate, apply pressure to force the mandrel into the roll of film and proceed to center it on the mandrel.
See Figure 8-1.
Place the loaded mandrel on the laminator. Insert the right side first and then lower the left side into the roll bracket
Take the top supply mandrel (labeled “Top”), insert it into the roll of laminating film, and place it in the top position as
with the lower (process shown in photos 9-1, 9-2).
Note: 1” core laminating film is rolled adhesive side in (”poly in”). When loading fim on mandrel, be sure roll is posi-
tioned correctly to unroll as shown in figure 8-1. If the roll is loaded in reverse, the film could adhere to the laminator
when heated.

Note: When loading your laminating film, check for film splices.
These rolls will be clearly marked. Splices are not common,
but are unavoidable. If you find a spliced roll, place it in the top
position on the laminator so that the splice can be monitored
carefully. When the splice is ready to come through the laminator,
turn the drive and heat off, allow the machine to cool, and rotate
the roll of film by hand so the film tension is very loose. Turn
the drive switch on again and allow the splice to run through. If
necessary, keep turning the roll of film by hand to keep it slack
until the splice has passed through.
Caution: Do not apply excessive force to the ends of the
mandrel (i.e. with a hammer, etc.). Excessive force will
damage the mandrel. When loading the laminator, be sure the
heat is turned off and the machine is cool to avoid chance of
burns.
Note: Film rolls must be centered on supply mandrels.
If the rolls are not aligned, hot adhesive will be deposited on the
heatshoes and rubber rollers, necessitating a cleaning operation.
Caution: When loading the laminator for the first time, be sure
that the heat is turned off and the machine is cool.

THREADING DIAGRAM
Figure 9-4
Photo 9-2

10
Thread the top roll of film under the idler roller as shown in the
threading diagram on previous page (see Figure 9-4). Pull the
film down so that the films lead edge is below the lower heat
shoe. Next thread the bottom roll of film under the lower idler
bar pulling film upward until it is even with the top heat shoe
(the film will overlap). Tape it to the top film edge. This creates
a film “Web” (Photo 10-1 & 10-2).
Using Tension Adjustment knobs, loosen tension on both rolls
of laminating film. Turn the speed control knob to a slow
speed. Turn on the “Drive” switch and using the threading
board—push the film web into the laminating rollers. This
process will push the web into the pull rollers and exit. Ensure
that the threading board and film exit between the rear pull
rollers (Photo 10-3 & 10-4).
NOTE: If you lose your threading board or if it becomes
damaged, you can make your own with a piece of poster
board. Cut poster board 12” wide by the length of the
laminator (18” or 27”).
Your laminator is now loaded and ready to be heated. Remove
the threading board and save for your next use.

HEAT SETTINGS
Turn the heat on by depressing the main heat power switch on the left side panel. The red indicator light will illuminate
and remain lit while the heat switch is in the on position.
The display board on the right side panel will now illuminate and show the current set temperature. To set the tem-
perature, rotate the control knob located below the display
(Photo 11-2). The new temperature will be displayed immediately. The heat indicator lamp
will be illuminated while the machine is heating, and will turn off when set temperature is reached. To see the lamina-
tor’s actual running temperature, depress the ACT button on
the display board.
Prior to laminating, allow the machine to pre-heat at least 15 minutes in order to stabilize the
temperature. Temperature settings depend on the film type being used. The temperature is preset at the factory, but
may require adjustment depending on what type of film you are using.
Note: When setting the heat to a temperature below 200°F, first rotate the heat control knob fully clockwise and then
proceed to set to desired temperature.
The display can easily be toggled between Fahrenheit and Centigrade by depressing the
C/F button.
Photo 11-2

12
TENSION
To adjust tension for upper and lower rollers, the laminator must be loaded and heated.
Remove the heat guard and feed tray. Loosen both tension control knobs by turning counterclockwise until there is no
tension on upper or lower film rolls. Photos 13-1, 13-2.
Film should pull freely.
Turn the drive switch “On” and set to a slow speed
As film runs through it will appear wrinkled and bubbly, as pictured in photo 13-3.
Gradually increase tension on both rolls, by turning knobs clockwise, until film is smooth
on heat shoes. Once film is smooth, stop tightening knobs.
NOTE: For best results, reset tension with EACH new pair of film rolls.
NOTE: As the film roll supply becomes low it is necessary to decrease tension on the rolls.
NOTE: Too little tension on the top or bottom roll causes vertical or diagonal streaks in the
film as it passes over the heating shoe.
WARNING: Excessive tension will lead to increased wear and tear on the laminator.
Once the laminator is loaded, heated, tension adjusted—install the Feed Tray and Heat Guard, as shown below in
Photos 13-4 and 13-5.

RELOADING A NEW ROLL OF FILM
ON A HOT LAMINATOR
Allow the old film to run to a point just before it pulls off the cardboard cores.
Turn the drive switch to “OFF.”
Cut the film web with a blade so that
approximately 5” of film extends beyond
the idler bar. Photo 14-1.
CAUTION: When using a sharp object to
cut film (blade or shears), avoid contact
with heat shoes or rubber rollers.
Remove the old cardboard cores and replace with new rolls of film. Photo 14-2.
Loosen the tension on the top film roll.
Thread the new web of film around the
idler bar and tape it to the remaining
segment of the expended roll.
Photo 14-3.
Repeat this procedure for the bottom
film roll. Use caution when threading film
near hot heat shoe .
Run film through the laminator until the
new web of film clears the pull rollers.

CLEANING THE HEAT SHOES
Photo 15-1
Photo 15-2
With continuous use the heat shoes and rubber rollers may
accumulate adhesive and dirt. It is recommended that you
periodically inspect them for adhesive build-up. Use USI’s
Laminator Cleaning Kit, which contains cleaning fluid, a coarse
scrubbing pad and a mesh covered sponge, for removal of any
adhesive build up.
Moisten the sponge pad with poly-off cleaning fluid and wipe down
the heat shoes.
NOTE: Be sure to clean the heat shoes only when the laminator is cool.
CAUTION: Teflon coated heat shoes are scratchable.
CLEANING THE RUBBER ROLLERS
Photo 15-3
If indentations begin to appear on the surface of finished
laminations, this may indicate that cleaning of the rollers is
necessary.
Periodically inspect the rubber laminating and pull rollers for
adhesive build-up.
Remove the upper heat shoe to gain access to the laminating
rollers for cleaning.
Before cleaning be sure the laminator is cool.
Use a dry Scotch Brite® pad to remove excess adhesive from the
rollers. Photo 15-3.
Turn the drive switch on and off to advance the rollers and clean
each section at a time.
Wipe clean with the sponge pad and cleaning solution from USI’s
Laminator Cleaning Kit.
NOTE: Use cleaning solution sparingly. Do not allow to “run” onto
wiring or into “ends” of laminator.
WARNING: Do not use any sharp metallic objects or steel
wool to clean the rubber rollers. Use of such abrasive objects
can damage the rubber surface of the rollers. USI strongly
recommends the Laminator Cleaning Kit for all of your
cleaning needs.

Photo 20-2
STEP 11:
To install a new roller or replace the original roller, reverse the removal procedure. Be sure to properly reposition
the sprockets and align the chain. All three sprockets should be in line with each other. Since the motor sprocket
was not removed, use it as a guide for alignment of the pull roll and laminating roll sprockets.
NOTE: See page 24 for additional information on a sproket alignment & tightening.
• The pull rollers on this laminator are interchangeable
with the laminating rollers. If the laminating rollers have
minor damage, each can be replaced by pull rollers. If
the laminating rollers are too badly damaged, they must
be replaced. The condition of the laminating rollers is
very important for a good lamination.
• If the chain feels too loose, it may be tightened as follows:
Loosen the motor mounting screws. Push down on the
motor sprocket and refasten the motor mounting screws.
Photo 20-2.
NOTE: Be sure to adjust the pressure on both pressure adjusting screws. 2-3 threads should show through the
adjusting screw mounting bracket. See page 21.

PRESSURE
The pressure settings for the rubber rollers on USI Laminators are preset at the factory and should not require adjusting.
In most cases, it is necessary to adjust pressure after the rollers have been removed for service. (Generally this is the
only time an adjustment is required.)
If an adjustment is necessary, disconnect electrical power and remove both the left and right housings.
Locate the Slotted Screw holding Compression Spring. Slotted Screw and Compression Spring locations are
identical on both sides of the laminator. Photo 21-2.
To increase pressure, turn the flat head screw clockwise.
There should be 2-3 threads of the screw showing
through the bottom of the bracket. Photo 21-3.
WARNING: It is extremely important that pressure
adjustments are always made exactly the same on both
sides of the laminator in order to maintain even pressure.
