RESIDUAL hEAT – hEAT BUILD UP
The machine is designed to allow sufficient time
for the heating element and sealing compression
pad to cool during the bag dispensing and filling
period. It is not intended for use as a high-speed
heat sealer. Attempting to operate the sealer at
speeds beyond its intended use causes residual
heat build-up resulting in bag seal stretch and
melt-through and require early replacement of the
heating element, Teflon
®
covers and compression
pad.
BAG STOP POSITION ADJUSTMENTS
If the bag in the staging area opens properly, fill it,
tear it off and heat seal it. The next bag dispenses
during the heat-sealing cycle. If the bag does not
stop in the correct position, follow the instructions
below. This is trial-and-error; when using bags of
different lengths, write down the proper settings as
you determine them. The settings will vary slightly
from one machine to another. Initial set-ups may
take a few minutes.
IF BAG STOPS TOO LOW ON ThE MAChINE
Decrease the BAG LENGTh setting slightly
(counterclockwise). Use the coarse or fine
adjusting control as needed.
Flip the BAG ADJUSTMENT switch up or down
until the next bag is in position for filling.
Fill, tear off and heat-seal the bag.
Repeat until the next bag stops in the proper
position each time.
IF BAG STOPS TOO hIGh ON ThE MAChINE
Increase the BAG LENGTh setting slightly
(clockwise). Use the coarse or fine adjusting
control as needed.
Flip the BAG ADJUSTMENT switch up or down
until the next bag is in position for filling.
Fill, tear off and heat-seal the bag.
Repeat until the next bag stops in the proper
position each time.

JAW COVERS
Both the upper and lower jaws of the heat sealer
are covered with a Teflon
®
glass cloth to aid heat
sealing and prevent sticking. Since the heat source
is in the lower jaw it is exposed to greater abuse
and is therefore larger and easily repositioned.
REPLACE UPPER JAW COVER
Replace the upper Teflon
®
cover if it becomes
torn, burned or the sealed bag sticks to it. It is held
in place by a spring and is easily replaceable.
REPOSITION LOWER JAW COVER
The lower Teflon
®
cover provides an easily
repositionable sealing surface. The cover is
anchored at one end to a roller held in place by
two screws; the other end passes through a clamp-
type retainer on the face of the machine.
To reposition the lower Teflon
®
cover:
Loosen the two plastic screws holding the
clamp.
Using either one or both of the knobs located
on the sides of the machine, rotate the roller
slightly so that a new seal area is positioned
over the heating element. (See Figure 6)
