3 SAFETY PRECAUTIONS BEFORE OPERATING THIS VACUUM CLEANER, READ THIS SERVICE MANUAL THOROUGHLY, AND OBSERVE EACH POINT CAREFULLY. 1. Motor filter(air Cleaner) 1) This filter is reusable. 2) Never use the vacuum cleaner without filter.

Never use hot water for washing the filter. Reuse the filter after drying it completely in the shade for a half day. Do not dry near fire or direct sunray. Do not brush the filter. This will cause permanently damage allowing dust to by-pass the filter. 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 clean filter is clogged or not. 7. Electric shock could occur if used outdoors or on wet surfaces. CAUTIONS BEFORE ATTEMPTING TO SERVICE OR ADJUST ANY PART OF THE VACUUM CLEANER, DISCONNECT THE ELECTRICAL POWER SUPPLY CORD FROM THE WALL OUTLET. 1. Motor exchange 1) Separate the Body Cover and Body Base by unfastening the screws. 2) After disconnecting the lead wires, replace the old motor with a new one. 2. In case of exchanging other parts. refer to the exploded view. 3
