Safety Instructions
WARNING! Below are general safety precautions and warnings that should be
understood prior to setting up or operating your equipment. Read and fully understand all instructions and
warnings prior to using this unit. Your safety is most important! Failure to comply with procedures may
result in serious injury or property damage. Remember: Your personal safety is your
responsibility.
Unsafe practices or unauthorized modifications could result in accidents or property damage. Failure to
follow these safety rules and take necessary precautions can result in serious injury as well as damage to
equipment. Failure to comply with the safety instructions would also void the warranty.
Never operate or service your sealer until you have read this manual completely and understand it
fully.
Only plug the sealer into a standard 120 Volt, 60Hz wall outlet or surge protector.
Do not use the sealer if the power cord, plug or any other parts are damaged. Do not to allow the
power cord to drape into your work area. Check that all parts are operating properly and perform
the intended functions. Check for any worn parts before starting operation. Check for all other
conditions that may affect the operation of your sealer.
Reduce risk of unintentional starting. Make sure the power switch is in the "OFF" position before
attaching to the power source.
Always disconnect sealer from power source before servicing, changing accessories or cleaning the
unit.
To provide protection against the risk of electrical shock, the power connection must be properly
grounded at all times.

Introduction
W-Series L-bar sealers are designed for quick and easy shrink film packaging. The L-bar sealers allow
youto create sealed packages using centerfold shrink film in one step, producing products that have a
factory fresh clean look and feel. Our L-bar sealers will create packages that are free from dust, moisture,
fingerprints, and tamper-proof.
Features of the W-Series L-Bar Sealers
Your L-bar sealer is equipped with a wide range of standard features and capabilities.
Ideal for quick and easy shrink film packaging
Steel construction for heavy duty use and durability
Adjustable height work table for sealing packages of different heights (1" increments)
Heating element located on the upper jaw of the sealer
Included: film roller, twin perforating hole punch, film separator, work table, and up right heat gun
holder (w/ built in electrical outlet)
How Do W-Series L-Bar Sealers Work?
Our W-Series impulse sealers fire a short burst of electricity through a specially
designed heating wire to weld thermoplastic materials together. The length of the
seal time will depend on the sealing characteristics of the bag being sealed. The
sealing process is simple: The operator places material on the base of the sealer
and brings the sealing arm down to seal. The sealer will create an "L-shaped" seal
sealing two sides of your package.

Operating your Sealer
Important
Read this manual carefully, and make it available to everyone involved with the supervision, maintenance,
and/or operation 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
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:
Adequate power source
Relationship to source of product
Relationship to any conveyors necessary to remove finished product
Convenience of operator
1. Your new L-Bar sealer comes wrapped on a pallet to protect it. If your machine does not arrive in this
condition, write on shipping paperwork that the box is damaged. Concealed damage may have occurred.
Figure 3. W-Series L-Bar on Crate
2. Once you remove the shrink wrapping, there will be two boxes. The first and larger box holds the L-Bar
sealer and the second box holds the film roller.

W H L I N S T R U C T I O N M A N U AL

3. Attach the film roller to the sealer using the four screws provided.
4. Adjust the bottom base of the L-bar sealer to the height of your product. Five options are available
staring at 7 1/4" to 11 1/4" moving in 1" increments.
Operation
1. Before operating, check the heating element, PTFE cover, PTFE adhesive and the
silicone rubber. The heating element should be intact.
2. Insert the power cord into the correct receptacle (110V).
3. Turn the power switch on.
4. Set the timer knob to the lowest setting. Always start with a low setting and increase gradually as
needed.
5. Pull the film to be sealed.
6. Place the object to be sealed between the sheets of film. Place right hand on package and slide
product into the sealed left edge (i.e. corner formed by folded rear edge of film and previously
sealed left edge of film). Keep the object and film as close to the seal bars as possible for best
quality seal. We recommend 1/2" to 1" of extra film around the package.
7. Press sealing handle down. Release when the timer light is turned off.
8. Repeat steps #6-7 on your next package.
Tips for Successful Sealing
1. If the seal is broken or damaged, decrease the sealing time.
2. If the seal is not fully welded, increase the sealing time.
3. Always keep the sealer clean. Remove any residue found on the platform and PTFE cover. Silicone
spray may be used for this purpose.
4. Occasionally check the condition of the ceramics (holds the element in place). A damaged ceramic
will affect the quality of the seal.
5. Occasionally check the condition of the silicone rubber for wear or burns. A damaged silicone
rubber will affect the quality of the seal.
6. Be sure to turn off the power or unplug the unit before replacing any parts.

Maintenance
The following maintenance procedures should be followed to ensure the longevity of your W-Series Long
Hand sealer.
Inspection and Cleaning
1. Inspect your machine daily.
2. Use a clean cloth to remove any plastic residue remaining on the PTFE adhesive.
3. When replacing the elements, always replace the PTFE adhesive.
4. Check the condition of the ceramics for wear and tear. A damaged ceramic will affect the quality
of the seal.
5. Check the condition of the silicone rubber for wear and burns. A damaged silicone rubber will
affect the quality of the seal.
Replacement Kit Instructions
W-Series L-Bar sealers will require new heating elements and PTFE from time to time. Heating element will
break through wear and tear. A good rule of thumb is to replace the bottom PTFE adhesive every time you
change your heating element. The top PTFE adhesive prevents the plastic or other thermoplastic material
you are sealing from sticking to the heating element.
Replacement kits are available from your distributor. Kits include (2) heating elements and (4) PTFE
adhesives.
For replacement kit part #s, refer to your model #.
