Before using, always verify the voltage specification of your particular unit and operate it at the
correct voltages. Please note the following.
1 The voltage specification of your unit is listed on the label which displays the serial
number. This label can be found on the machine body.
2 Please confirm the plug configuration on your specific unit. The explanations and
illustrations in this operator's manual utilize the plug configurations most common in
Japan.
The following marks are used in this manual to easily identify the conditions of risks, damages,
or some tips for the optimal use of your unit.

1The impulse sealer is a machine which sends strong electric current quickly to the thin ribbon heater,
which presses against the film and instantly heat seals the package. Though this machine yields
superior quality sealing, it is not compatible with films thicker than that indicated in the diagram
below, sponge-like sheets, and materials which are not able to withstand high heat.
2Film thickness limits for the OPL series are described below. The machine cannot seal bags which
are thicker than that indicated. The machine may malfunction if you try to exceed the limits of the
machine.

11
Warning In an emergency, unplug the power cord
immediately
This sealer incorporates a number of safety devices and is carefully
designed to prevent fires or other malfunctions. However, should all of
the safety devices fail simultaneously, there is a possibility of the fluoro
glass sheet catching fire due to a failure of the heating circuit's tripping
mechanism that results in the heating element overheating. Should
smoke or fire appear from the fluoro glass sheet, immediately turn OFF
the power from the outlet.
Warning Confirm proper electric power source
Make sure power source has the specified voltage and electric power as
to your machine model. DO NOT use an extension cord, as the machine
may malfunction due to voltage drop or may result in fire.
Machine will malfunction if connected to anything other than the
specified voltage.
Insert the electric power plug fully into the outlet.
Warning Do not use for packaging liquids
Do not splash water on the machine or use machine for packaging
liquids since machine is not waterproof. There is a danger of
electrocution or malfunction of the machine.
Warning Do not insert any metal objects into the sealing area
Please do not place any metal objects into the sealing area during
operation. This could cause electrocution.
Warning When replacing parts, unplug the power plug
Maintenance of the machine is important. Parts should be replaced in
accordance with the operating instructions. There is a risk of danger if
the parts are not replaced properly. Before replacing parts, unplug the
machine from the power source and replace parts referring to “8 Proper
XVHRIWKHVHDOHU´ĺSDJH17) thoroughly.
Warning Do not modify the machine
Modification of the OPL series or the use of unspecified parts may not
only lead to damage of the machine, but there is also a risk of danger to
the operator. Please do not tamper with the machine. Accidents or
damage caused by modification by the customer is the sole
responsibility of the customer.

Caution Do not use in the following places
Do not operate machine in the following places since there is a danger
of malfunction:
1Dusty locations.
2Locations not within normal temperatures.
3Locations with high humidity.
Warning Do not use parts other than those specified
When replacing parts, always use only specified parts sold through
Van der Stahl Scientific. We are not responsible for malfunctions
caused by the use of unspecified parts.
Warning If the power switch automatically turns to the OFF
position
1If after 4 seconds heating is not complete after it has been
initiated, the power switch will automatically turn OFF.
There is a possibility of malfunction of the machine. Do not
operate the machine until the cause of the shut down is
ascertained and the problem has been addressed.
2The power switch automatically turns OFF when the power
cable is inserted with the power switch ON position. This is due
to the safety circuit function and not a malfunction. Make sure
if the power switch is turned OFF before inserting the power
cable.
Caution Do not place hands in the sealing area
1With prolonged use, the sealing area will retain heat and
become hot.
2Never place your fingers or hands in this area (between the
pressure lever and the seal frame).
3The machine is designed so that pressure will be released and
the lever returned to an open position if there is an object
caught in the seal area and the heat cycle is not activated within
0.8 seconds. However, pressure is particularly strong at the
edges of the seal area. Please be aware there is a possibility that
the heat cycle may be activated if the object is caught in the
edge of the seal surface.
Caution Use the machine properly
Read the operating instructions carefully and operate sealer correctly.
Accidents or damage caused by misuse of the machine not in
accordance with the operating instructions are the sole responsibility of
the customer.

OPL (USA) Series Operating Instructions Ver. 3.02E

ƔTo achieve a strong seal
Proper sealing pressure is important in achieving a strong seal. Follow
directions on proper sealing pressure adjustments and set accordingly.
Refer to ³6HDOLQJSUHVVXUHDGMXVWPHQWPHWKRG´ĺSDJH25).
ƔDust in the sealing area
Dust will prevent attainment of a smooth seal. It could also cause
damage to heating element and/or other routine maintenance parts.
Before using the machine, clean the sealing area.
ƔHeating temperature should be set at a minimum
Set sealer so that an acceptable seal is completed at the lowest heating
temperature. Excessively high heating temperatures will damage the
fluoro glass sheet, glass tape and other consumables, as well as result in
heating element breakage. This will lead to decreased work productivity
and unnecessary power consumption.
ƔSet the cooling temperature depending on the film
Cooling process is important when using an impulse sealer. After the
film is heated, the film must cool with the frame and pressure lever in
the closed position. Setting the cooling temperature excessively low
will decrease the work productivity. Set the cooling temperature that is
suitable for each film.
ƔWhen the fluoro glass sheet, silicone rubber becomes
damaged
The fluoro glass tape and silicone rubber will start to wear with use.
Once they are damaged, it will be difficult to achieve smooth and
strong seals. Thoroughly read how to replace the parts and be careful
when doing so.
For smooth operation

OPL (USA) Series Operating Instructions Ver. 3.02E
14
Do NOT attempt to plug any other electronic devices into this outlet.
ƔRun test trials first before beginning operation
Find the optimum sealing conditions by conducting seal tests before
proceeding. Achieving a superior seal with an impulse sealer is
determined by heating / cooling / pressure strength. Depending on the
type of film being used, heating / cooling / pressure strength conditions
will differ. Run test trials to find the optimum sealing condition on
customer’s responsibility, especially when trying to find the tightest
seal possible.
ƔThe OPL series is an impulse sealer
Do not become alarmed if the sealing area does not become hot after
the power switch is turned to the ON position. The machine has not
malfunctioned.
The sealer uses an impulse method so the heating element will not
become hot just by plugging the unit in or turning the power switch to
the ON position. The heater will only become hot for an instant when
the heating process is in operation. However, after extended periods
of use, the sealing area may become hot.
ƔPrinter outlet
The printer outlet is located on the underside of the seal frame head. It
is to be used ONLY when mounting the optional printer.
ƔShould an abnormality occur in the temperature sensor
The heating section is controlled by a temperature sensor mounted
directly at the seal surface. Should the tip of this sensor slip off the
heating element the machine will fail to function properly. When
replacing the heating element and other routine maintenance parts, take
great care to ensure that the temperature sensor is correctly placed (in
direct contact with the heating element.)
