6 Operating precautions
For safety operation
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 Teflon
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 Teflon, 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 explained in “1 Specification” of this manual. 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 wall 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
“Replacing the routine maintenance parts” 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.

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 OFF
If after 3 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.
Caution Do not use in the following places
Do not operate machine in the following places since there is a danger
of malfunction:
Caution Do not place hands in the sealing area
1With prolonged use, the sealing area will retain heat and
become hot. If you place your fingers in this area, there is a
possibility of burns.
2Do not place hands between the seal jaws (pressure lever and
seal frame).
3Should the foreign objects such as fingers are clamped between
the sealing area and the sealer cannot move to the heating
process within 0.8 seconds, the lever automatically returns to
the initial position. However, the strong pressure is applied
especially to the both ends to the sealing area, and there a
danger that the sealing process may start without notice.
Caution Use the machine properly
Read “Proper use of the sealer” in this manual 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.

ƔTo 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 “10-1 Adjusting the seal pressure”.)
ƔDust 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.
Ɣ+HDWLQJWHPSHUDWXUHVKRXOGEHVHWDWDPLQLPXP
Set sealer so that an acceptable seal is completed at the lowest heating
temperature. Excessively high heating temperatures will damage the
Teflon, glass tape and other consumables, as well as result in heating
element breakage. This will lead to decreased work productivity and
unnecessary power consumption.
Ɣ6HWWKHFRROLQJWHPSHUDWXUHGHSHQGLQJRQWKHILOP
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.
ƔWhen the Teflon, silicone rubber becomes damaged
The Teflon, 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



Do NOT attempt to plug any other electronic devices into this outlet.
ƔRun test trials 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If there is a malfunction in the temperature sensor
The temperature sensor is designed to monitor and control heating
temperature by directly measuring the heater temperature. Therefore,
the machine will not operate when the sensor tip is not positioned
correctly or the sensor is disconnected.
When replacing the consumable parts such as heating element or the
temperature sensor, please be sure to position the temperature sensor
correctly. Please refer to “9-8 Replacing the temperature sensor” for the
detail.

8-10 Seal with the selected operation
mode
8-11 Finishing sealing
Caution The sealing area become hot with the
prolonged use, and there is a danger of
burning.
Also, it is extremely dangerous to place
fingers to the sealing area where the
strong pressure is applied. The machine is
designed to release the pressure when the
microswitch is not activated within 0.8
seconds due to the foreign objects being
inserted to the sealing area. However, the
strong pressure is applied especially to
both ends of the sealing jaws, and the
sealer may start heating. (Especially for
OPL-450 and 600 series.)
