Read all instructions before use. Save these instructions for later use.
Follow all warnings and instructions marked on the product.
Unplug this product from the power source before cleaning and/or changing any parts
Do not rest anything on the power cord. Do not place the machine where the power cord may be stepped on or pulled.
Always keep out of reach of children and pets.
This sealer should only be in use with an operator in attendance.
Never insert clothing, hands, fingers between the sealing jaws of sealers.
Never touch the heating elements with bare hands while the sealer is plugged into a power source, or in operation, or just finished operation. It will be HOT.
Be sure to check for worn parts before starting operation.
Do not operate with a damaged power cord or plug.
Always keep the unit clean. Do not use water. Silicone spray may be used to clean the unit. Be sure the unit is unplugged from the power source before cleaning.
When changing blade (for sealers with cutters), be careful of the sharp edge.
When changing the teflon adhesive, be sure the entire surface under the heating element is covered with a teflon adhesive. Bend down the excess teflon adhesive on both ends. This prevents the heating element from breaking and the machine from grounding.
When replacing the fuse, be sure the exact voltage and ampere is used.
Be sure to keep a record of your model number. Specify this number when ordering parts.
When replacing any parts, be sure to mark down the exact locations of the connections.
OPERATING INSTRUCTIONS
Before operating, check the heating element, Teflon cover, Teflon adhesive and sealing pad (silicone rubber).
Set the Power Switch to the ON position.
Adjust the timer setting according to the thickness of the sealing material. Note: Always start with the lowest setting and gradually increase to the correct setting.
Pull the film to be sealed in between the base and sealing jaw.
Place the object to be sealed between the sheets of film.
Press the sealing bar down and seal.
Wait 2-3 seconds to allow the seal to set and lift the handle. For Cutter Models, slide the cutter unit to cut the bag.

ADDITIONAL INFORMATION
Always unplug the unit from the power source before attempting any maintenance.
Always keep the sealing platform clean and remove any residue found on the platform and Teflon tape. Silicone spray may be used for this purpose.
When replacing the Heating Element, always check the condition of the Teflon Tape.
Occasionally check the condition of the Silicone Rubber for wear and burn. A damaged or worn Silicone Rubber will affect the quality of the seal.
