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.
