Warning In an emergency, unplug the power cord
immediately
V-301G series incorporates a number of safety devices and is carefully
designed to prevent fires or other malfunctions.
However, should all of safety devices fail simultaneously, there is a
possibility of 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.
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.
Warning Do not use for packaging liquids
Do not splash water on V-301G series 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 Confirm proper electric power source
Make sure power source has the specified voltage and electric power as
explained in the operating instructions. Do not use an extension cord, as
the machine may malfunction 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 let the nozzle suck the liquid
When vacuum packaging the watery (liquid) items, please be careful
not to let the nozzle suck the liquid. The optional large filter will be
required for packaging those items.

Warning Do not modify the machine
Modification of V-301G 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 temper with the machine. Accidents or
damage caused by modifications 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
1 Dusty locations.
2 Locations not within normal temperatures.
3 Locations with highly humidity.
Caution Use machine properly
Read this operating instructions carefully and correctly operate sealer.
Accidents or damage caused by the misuse of the machine, or against
the operating instructions are the sole responsibility of the customer.
Warning If the power switch automatically turns OFF
If heating is not complete within 3 seconds, the power switch will
automatically turn to the OFF position. There is a possibility of the
machine malfunction.
Do not operate the machine until the cause of the shut down is
ascertained and the problem has been addressed.
Caution Do not place hands in the sealing area
With 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.
In addition, sealing pressure is very strong. Please take sufficient care
not to pinch your fingers.
Caution Be careful of the nozzle
After the sealing process, nozzle comes forward automatically.
Please take sufficient care not to put hand or face close to nozzle,
beside if the sealed pouch is still left on the sealing area, advanced
nozzle might hurt the contents.
Caution When the frame cover is opened
Inside the sealer's body, there are metal plate parts which have sharp
edge.
If the frame cover would be removed for the replacement of parts,
please take care not to be injured.

●Heating time should be set at a minimum
Set sealer so that an acceptable seal is completed in the least amount of
heating time. Excessively long heating times (increasing the heat
setting unnecessarily) 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.
●Allow sufficient cooling time
Cooling time 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.
Release the table after “beeping” (indication buzzer for seal
completion) sounds. If the table is released before the buzzer, seal
performance will result in poor. Refer to "8-12 Take sufficient cooling
time" for the detail.
●When the fluoro glass sheet, silicone rubber becomes
damaged.
The fluoro glass sheet, 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.
●To achieve a strong seal
Proper sealing pressure is important in achieving a strong seal. Follow
directions on “11 Adjusting seal pressure” and set accordingly.
●When operating machine for extended periods of time
The machine's temperature will rise upon prolonged use of the
machine. As the temperature of the machine rises, the condition of the
seal will change. Thus, heating time should be shortened and cooling
time should be lengthened accordingly.
●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.
●When the sponge pad is damaged
The damage on the surface of a sponge pad can cause an air leak during
vacuuming. You may hear the air leakage sound. If so, please remove
the sponge pad and check whether there is any damage on the surface.
If it is damaged, replace to the new one or use the other side with no
damage.

●Run test trials before beginning operation
Depending on the type of film being used, heating / cooling / pressure
strength conditions will differ. Run test trials to find the optimum
sealing condition, especially when trying to find the tightest seal
possible.
●The V-301G series is an impulse sealer
Do not become alarmed if the sealing area does not become hot after the
power switch is turned ON. The machine has not malfunctioned. The
sealer uses an impulse method so that the heating element will not
become hot just by plugging the unit in or turning ON the power switch.
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.

Turn the heating timer dial to set a heat timer.
The bigger the scale number is, the longer the heat time
will be.
[Dial 1 ~ 10 = about 0.1 ~ 2.3 seconds.]
Depending on the film or bag, the required heat time
will differ. Set the heat timer at minimum required to
make a sufficient seal. It will increase the work
efficiency and avoid the unnecessary power
consumption.
The power cord is located on the left side of the
machine, when facing toward it. Make sure the
electrical outlet has adequate current carrying capacity
as described at “1. Specification.” Insert the electric
power plug fully into the wall outlet.
Turn ON the power switch. The power lamp will turn
ON.
Set the heating and gas-flushing time with the timer
unit. The sealing condition will vary depending on the
pouch/ film material, thickness and size. Reset the
sealing condition every time you change the pouch/
film.

Please hold the table in the down position until you hear
the beep sound to allow the sufficient cooling.
Release the table after you hear the beep from the
machine. This “cooling” process is required for V-301G
series as the seal must be cooled while applying
appropriate pressure to give it a clean finish.
After the heating and cooling cycle has finished, the
pressure lever returns to the initial position, and the
sealing is complete. If a sealing is not clean enough,
adjust the heating time or sealing pressure.
