Setup & Suggestions
• Locate the press on a rm, sturdy work surface. It is recommended to
bolt the press to a workbench using the rear and front mounting holes
on the base frame. The clamshell presses can “hop” when opened
abruptly, especially with the auto-release upgrade. This can cause
undesirable movement of the work on the bottom table. Bolting the
frame of the press to the workbench greatly reduces this.
• The height of the bench/work space the press is located on would be
ideally 27” to 32” high. The higher the press, the more difcult to
close/lock.
• Attach the power cord from the rear to the backside of the controller.
There is a power inlet on the back panel of the control box for the
power cord.
• Make sure the power cord can not be pulled on. Make sure there is no
tension on the inlet socket that the power cord plugs into
• The press should remain in the unclamped OPEN position when not in
use. Do not leave the heater block closed on the table when not using,
unless transporting.
• Do not leave the platen down on the silicone pad when heating. Always
leave the heat platen in the UP position.

WARNING: The heat platen
will become detached from the frame
and drop onto the table if it is adjusted
too far.
Please use caution when attempting
to increase pressure by turning the
knob to the left (unscrewing: counter-
clockwise).

Guidelines & Standard Settings
The following information covers some basic guidelines for pressing,
as well as some generic parameters for basic heat transfer applications.
• When pressing shirts, it is often recommended that the shirts be quickly
pressed for 2 to 4 seconds before transferring to remove wrinkles and water
content.
• When pressing two sides of a garment, pull the garment over the table so
that the printed side drapes underneath the table. This will avoid reheating
previously transferred designs on opposite sides of garments. It will also
avoid any bleed-through of inks on lighter fabrics.
• Avoid laying collars, cuffs, zippers, and other bulky parts of garments
on the lower table, as these can adversely affect pressing conditions, and
reduce the life of the silicone pad.
• When pressing rigid substrates (plastics, metals, woods, etc.), be sure that
any protective lms or laminates are removed before heating.
• Always check that the transfer image is face down against the material, to
avoid sealing the image against the heat platen instead of the substrate.
Always follow the transfer media suppliers instructions when
pressing. The information below is for general reference only, and may
not be as accurate as the instructions provided by the transfer media &
imprintable substrate supplier.
• Hot Split Supplier Transfers 350-375°F, 8-10 secs
• Puff Transfers 350-375°, 5-7 secs (extra heavy pressure)
• Ink-Jet Transfer Papers 360°, 15-18 secs
• ColorCopy/Laser Transfer Papers 375°, 20-25 secs
• Sublimation Inks (Polyester Fabrics) 400°, 35 secs
• Sublimation Inks (Plastics) 400°, 1 min, 15 secs
• Sublimation Inks (Metals) 400°, 1 min
• Sublimation Inks (Woods) 400°, 1 min, 15 secs
• Sublimation Inks (Ceramics) 400°, 4 min

To access the user menus, simply press TEMP & PRG at the same
time from the normal operating mode and let go.
(Try to use two hands and press the keys at the exact same time. If one
key is pressed too early from the other, the temperature setting or preset
modes may be activated instead. Turn the press off and then on and try
again.)

Maintenance
• The pressure adjustment screw is an area of wear and stress on the machine
and should be checked occasionally for loss of threading. Check the threads
of the pressure screw and the pressure block it screws into and replace if
needed.
• The handle arm and moving linkage is another area of greatest wear and
stress on the machine. The entire blue frame is one solid assembly, and is
easily and inexpensively replaceable when nally worn. Contact the factory
if pressure loss and obvious wear occur on the curved upper clamping
linkage.
• The silicone pad on the lower table can degrade after much use and over
an extended period of time. This pad is replaceable.
