IMPORTANT - PLEASE READ THIS CAREFULLY
The development of a good safety program, that is rigidly
enforced, is absolutely imperative when involved in the operation of
industrial equipment. Our machinery is well designed and includes
extremely important safety features. The part you the user play
through proper installation and maintenance procedures is of far
greater significance than our designs. Only properly trained
individuals following rigidly enforced safety rules, as recommended
by A.N.S.I. and O.S.H.A., should be allowed to operate these
machines.

UNPACKING
THOROUEXCELY INSPECT EQUIPMENT UPON ARRIVAL.
If goods are received short or in a damaged condition, it
is important that you notify the carrier’s driver before he leaves
your company and insist on a notation of the loss or damage
across the face of the freight bill. Unless this is done, no claim can
be enforced against the transportation company.
If concealed loss or damage is discovered, notify
the carrier at once and insist on an inspection. This is
absolutely necessary! A concealed damage report must be
made no later than ten (5) days from the date the shipment
was delivered. Unless you do this, the carrier will not
consider any claim for loss or damage. The carrier’s agent will
then make an inspection and grant a concealed damage notation. If
you give the transportation company a clear receipt for the goods
that have been damaged or lost in transit, you do so at your own risk
and expense.
All claims must be filed within 5 days of delivery date or
carrier will not accept them.

DESCRIPTION AND SPECIFICATIONS OF
MODEL SS-2028MK SEALER
DESCRIPTION
The purpose of a SS-2028MK Sealer is for medium to
high volume packaging requiring excellent seals and minimal
maintenance. It features “micro knife technology” for sealing of
films. This model incorporates an electromagnetic hold-down
system, allowing the operator to load another package while the
preceding package is being sealed. This system provides
consistent seals. In addition, a package take-away conveyor
increases production speed by automatically discharging product
into the tunnel.

INSTALLATION AND BASIC SET-UP
IMPORTANT
Read this manual carefully, and make it available to
everyone connected with the supervision, maintenance, or production
of this machine. Additional copies are available at your request.
(Contact your distributor for this information.) Be very careful when
operating, adjusting, or servicing this equipment. If in doubt, stop
and obtain qualified help before proceeding.
INSTALLATION OF SS-2028MK SEALER
Place the L-Bar Sealer in the desired location with
the required electrical power source available. (See
power requirements.) Make certain that proper electrical wiring is
provided to guard against low voltage. If the voltage is too
low, the equipment will not function properly.
Finding the proper location is a most important function
of the initial set-up. One must take several factors into
consideration:
1. Adequate power source.
2. Relationship to source of product.
3. Relationship to L-Bar Sealer.
4. Relationship to any conveyors necessary to remove
finished product.
5. Convenience of operator.
An electrician should install a plug on the end of the main
power cord. If there is any doubt, get qualified assistance to do the
initial installation. Do not take any chances!
INSTALLATION
Page 18
SS-2028MK Sealer Service Manual
Do not attempt to install, adjust, or operate this machine
without first reading the contents of this manual. Although the
design of the equipment incorporates safeguards to protect operating
and maintenance personnel, care should be used in operating,
adjusting, and servicing.
INSTALLING FILM RACK
IMPORTANT: Remove film rack from under sealer and
install at the end of the sealer on the right hand side with the four
bolts an center knob provided. Mounting holes are slotted for
adjustment, set film rack flush with backside of the machine frame.
INSTALLATION
Page 19
SS-2028MK Sealer Service Manual
MOUNTING FILM
Select the proper width of centerfold film for the item being
packaged, allowing for width and height of package. With the
package properly positioned within the film in the sealing area, allow
sufficient film to overlap the sealing bars so that a seal may readily
be made without any possibility of open areas due to insufficient film.
Place film roll on cradle mount film rack. The centerfold is to
be placed away from the operator, toward the rear of the machine.
Position film roll on rack and tighten film guide nuts to hold film roll
in position.
Thread film through the Pin Perforator. Note that the
perforator wheel turns freely and is not binding.
INSTALLATION
Page 20
SS-2028MK Sealer Service Manual
Once threaded, separate film top from bottom and insert
product tray between. Make sure that the centerfold of film is placed
at the rear of the product tray. This allows the operator to insert
product between the layers of film on the product tray and to
prepare to move product and film into the sealing area. When
threading film, make sure to pull more than sufficient film through
the rollers, across the product tray, and into the sealing area to
ensure sufficient film to begin operation.
Place product against rear of film separator tray. Then move
product into seal area. Be sure to leave the bag loose around the
product when making the seal. This helps eliminate the seals from
blowing out in the shrink tunnel. This completes threading and/or
mounting film.
INSTALLATION
SS-2028MK Sealer Service Manual
PIN PERFORATOR
Page 21
Located between the lower idler rollers, the pin perforator
creates holes for air escape as the operator pulls on the film. This
allows the air to escape as the package travels through the tunnel.
The pin perforator is adjustable and must be properly placed in
conjunction with the width of the desired package. The positioning
should always be re-evaluated when setting the machine for different
size product or different size film. Adjustments may be made with
the adjustment knob attached to the bottom of the film rack.
FILM BRAKE
INSTALLATION
Page 22
SS-2028MK Sealer Service Manual
The film brake is located on the operator side of the film cradle.
It serves to create tension on the dispensing film, in order to prevent
over-run and/or slack. From time to time, the operator should reevaluate its setting to ensure proper tension.
PRODUCT TRAY
The product tray is an adjustable metal platform used to
separate film and to insert product between top and bottom layers of
film.
The tray is adjustable to achieve proper depth, equal to the
depth of the package, allowing product to be placed exactly in the
centerfold of the film each time. A locking wing screw allows you to
set tray position.
INSTALLATION
SS-2028MK Sealer Service Manual
LOCKING WING SCREW
Once the product is placed in the desired location, tighten the
wing screw under the loading tray to lock tray in position.
Page 23
Power Discharge Conveyor
Lower Power Discharge Conveyor using the crank wheel located
underneath the Power Discharge Conveyor. The Conveyor should be
set so the package height is centered to the seal pad. In essence, ½
of the package is above the seal pad and the other ½ of the package
is below the seal pad. This will place the seal in the center of your
package and help release any film tension that may occur.
