3. CAUTION FOR USE
3-1 Caution for safety
1) In case of emergency, please pull off the electric cord. The machine has the
noise filter and the fuse to cut off any irregular electric shock. Nevertheless, if
there is any emergency such as breaking out of a fire on the Teflon tape, please
cut off electric inflow from the machine.
2) The electricity specified in the manual must be used and use of multi tap is
not recommended. Especially, Home-use multi tap could be cause of overheat,
short machine life, quality degradation and a fire. If the user has no choice but to
use multi tap, please consult with electric expert.
3) In case of exchanging any part of the machine, the electric cord must be
pulled off. And, to prevent any malfunction or accident, it is prohibited for the
user to use any machine parts different from the specification stipulated by the
manufacturer.
4) It is prohibited for the user to re-build the machine and its parts without
permission from the manufacturer
5) It is prohibited for anything except for vacuum bag to be inserted between
sealing bars.
* There is electric flow between sealing bars so that inserting metal material
could lead to electric shock.
(This machine uses earth wire to reduce the risk of safety accident.)
* Especially, Long time use of machine could accumulate heat on heat wire so
that if the finger is caught between the sealing bars it could result in burn as
well as hurting.
6) If the N.F.B turns off automatically, the cause must be checked and solved
before turning the N.F.B on again.(Refer to 17-3)
7) The user must avoid installing the machine in the place full of dust, high
temperature or high humidity. The temperature of work place suitable for this
machine is 0°C ~ 40°C; 30°and the machine must avoid any direct or continuous
air from air conditioner located within 10 m from the machine.
8) For any wrong work, press the STOP button or EMERGENCY button. Then, all
work is stopped and the nozzle moves back and the upper sealing bar go up.
9) Please check up whether there is any damage on the Teflon sheet, Teflon
tape and sealing rubber, compression sponge, the between sealing bars and
heat wire holder before use of the machine. Any damage on these parts could
result in short circuit around heat wire. Or, it could lead to wire’s exposure to air
during sealing resulting in overheat.

8
10) This machine must be used by any adult person who is trained well and can
use it without problem.
11) When you move this product, you have to move carefully and safety.
3-2 How to make a good sealing
1) Please check up whether there is any damage on the Teflon sheet, Teflon
tape sealing bars and heat wire. If there is any damage, exchange it with new
one.
2) Please check up whether the sealing bars are clean. Any alien substance on
there can make bad sealing result and can give damage to Teflon sheet, Teflon
tape and Heat wire
3) Before mass operation, please find out the proper vacuum, sealing and
cooling time through enough sealing tests
4) Please set sealing time as short as possible in the range that sealing is
possible. Too long sealing time can give damage to the Teflon sheet, Teflon tape,
heat wire, etc., which makes bad sealing result and causes low productivity and
high electric consumption
5) Please set enough cooling time 3 times or more than sealing time. Long
cooling time makes clean sealing result and avoids accumulation of heat on heat
wire leading to longer machine life.
6) Long and continuous sealing could raise the temperature of sealing bar. In
that case, please reset sealing time shorter and cooling time longer
7) In the case of use of pure PE bag or vacuum bag with thick PE film, set
cooling time 5 times more than sealing time. For pure PE bag with 200μ, about
sec. of cooling time is needed.

2) The clean-up way includes just blowing compressed air or soaking in warm water
& blowing compressed air. If the foreign material can’t be removed by any way,
replace it with new one.
3) Re-assemble it in the reverse order of disassembling.
10-2 Separation and clear-up of vacuum hose
Any foreign material hardly gets into the vacuum hose. But, up to the degree of
malfunction, in the case of replacement of broken parts, the front and back part of
vacuum hose need to be cleaned up.
10-3 Clear-up of vacuum filter
The vacuum filter is between the nozzle and the vacuum pump. It filters any foreign
material from the nozzle. Check this frequently and clean it up every time there is
any foreign material.
1) Turn the dust kit to the left (counterclockwise) and separate it. Be careful not to lose
the rubber ring which is stuck on the upper side of dust kit.
2) Clean the filter and the dust kit up using compressed air.
3) Re-stick the rubber ring on the upper side of dust kit and turn the dust kit to the
right (clockwise) to re-assemble it. If the rubber ring is not on the upper side of dust
kit, the vacuum cannot be carried out properly due to some leakage of vacuuming
power in the vacuum filter
