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 MS-350 NP 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:
1 Dusty locations.
2 Locations not within normal temperatures.
3 Locations with high humidity.
Warning Do not use parts other than those specified
When replacing parts, always use only specified parts sold through Fuji
Impulse. Not responsible for malfunctions caused by the use of
unspecified parts.
Warning If the power switch automatically turns to the OFF
position
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 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.
Do not place hands between the seal jaws (pressure lever and seal
frame). Should the foreign objects such as fingers are clamped between
the sealing area and the sealer cannot move to the heating process
within 0.5 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.
Caution Run test trials first before beginning operation
Achieving a superior seal with an impulse sealer is determined by
heating / cooling / pressure strength. Depending on the type of film being
used and the contents of the bag, heating / cooling / pressure strength
conditions may drastically differ. Find the optimum sealing conditions
by conducting seal tests before proceeding.
MS-350 NP Operating Instructions Ver 2.01E

● 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”.)
● 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.
● Heating 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
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.
● Set 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.
● When the Teon, 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

●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 Fuji Impulse MS-350 NP 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 Fuji impulse 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.
● 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 “10-2 Replacing the temperature sensor” for
the detail.

The pressure adjusting nut is adjusted to the
"NORMAL" position at the time of factory shipment.
The required sealing pressure varies depending on the
type and thickness of the film. Adjust the sealing
pressure according to each of the film to be used.
Perform the pressure adjustment referring to “11-1
Adjusting the sealing pressure.” Change the pressure
setting every time you change the film.
After completing the control unit and seal pressure
adjustment, turn off the auto-cycle mode and manually
perform the seal test to find the optimum sealing
condition to your film.

cycle interval mode
Automatic operation takes place based on the preset
intervals. Place a pouch to the sealing area according to
the timing that the pressure lever descends. You can
deactivate the auto-cycle mode by pushing the
Auto-Cycle START/STOP button.
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.

To stop the operation after the machine started working,
push the “ABORT CYCLE” button. The lever will
return to the initial position. The set value will not be
erased even if the “ABORT CYCLE” button is pressed.
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/ cooling time or sealing pressure.
As the sealing operation proceeds, the numeric value of
the counter increases own at a time from 0000 to 9999.
When you want to reset the counter to 0000, push
either ▲ or ▼ arrow buttons while the machine is in
the counter mode.

After finishing operation, always turn OFF the power
switch.
As the set value and the seal count are retained by the
control unit, there is no need to put the value every
time after turning OFF the power switch.
Unplug the power outlet in the case of not using the
machine for a while.
After use, please clean up the parts. Inspect parts such
as Teflon and heating element to make sure that they
are not damaged. If the parts appear to be damaged,
replace them referring to operating instruction.
