SAFETY PRECAUTIONS
BEFORE OPERATING THIS VACUUM CLEANER, READ THIS SERVICE MANUAL THOROUGHLY, AND
OBSERVE EACH POINT CAREFULLY.
1. Filter
1)
The filter is composed of a motor safety filter, a exhaust
filter and a paper bag or a cloth bag..
2) Never use the vacuum cleaner without filters.
It may harm the motor.
3) When the cloth bag, the motor safety filter and the
exhaust filter are soiled, wash the filter with neutral
cleanser.
NOTE : Re-use of the cloth bag, motor safety filter.
• Never wash the filter in a washing machine or in a
dishwasher.
• Never use hot water for washing the filter.
•
Re-use the filter after drying it completely in the shade.
• Do not dry near fire or direct sun ray.
2. Dust indicator
When the dust bag is full of dust, the indicator turns to red
(Suction power will be reduced). Then, change the paper
bag with the new one or clean the cloth bag.
3. Avoid sucking such materials as:
1) Liquid or wet dust :
Clogs the ventilation holes, reduces the suction power
significantly and harms the motor.
2) Inflammable liquids such as benzene, alcohol or
solvents.
3) Burning objects such as cigarette butts.
4) Bulky objects such as vinyl, paper etc.
5) Sharp objects such as needles, pins, metal or glass
particles etc.
4. Attachments

carpet.
• Crevice Tool : for cleaning any crevice, inside corners
of window frames. (However, do not use
the crevice tool more than 20 minutes.)
• Dusting Brush : for delicate vacuuming of fabrics on the
furniture, curtains, etc.
• Upholstery Nozzle : for vacuuming the dust on the
upholstery.
5. Close supervision is necessary when this
vacuum cleaner is used by or near children.
Children's carelessness may cause damage to
the cleaner or injure persons.
6. Air exhausted from the vacuum cleaner is
normally warm. But if extraordinarily hot air is
exhausted, check if the telescopic tube, hose
or dust bag is clogged or not.
7. Electric shock could occur if used outdoors or
on wet surfaces.
