Keep proper footing and balance at all times.
Do not fold, tug or step on the hose.
Stop the cleaner immediately if you notice poor performance or anything abnormal during the operation.
DISCONNECT THE BATTERIES When not in use, before servicing, and when changing accessories clean and service the cleaner immediately after each use to keep it in tiptop operating condition.
MAINTAIN THE CLEANER WITH CARE Keep the cleaner clean for better and safer performance. Follow instructions for changing accessories. Keep handles dry, clean, and free from oil and grease.
CHECK DAMAGED PARTS Before further use of the cleaner, a guard or other part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function.
Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any other conditions that may affect its operation.
A guard or other part that is damaged should be properly repaired or replaced by an authorized service center unless otherwise indicated elsewhere in this instruction manual.
Have defective switches replaced by the authorized service Center. Don’t use the cleaner if the switch does not turn it on and off.
REPLACEMENT PARTS When servicing, use only identical replacement parts.
STORE IDLE CLEANER When not in use, store the cleaner indoors.
Be kind to your cleaner. Rough handling can cause breakage of even the most sturdily built cleaner.

When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek
Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk of injury.
Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130°C may cause an explosion.
Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

Service

Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
Follow instructions for lubricating and changing accessories.
Keep handles dry, clean and free from oil and grease.

Otherwise the vacuumed dust or particles may be exhausted from the cleaner and they may cause respiratory disease to the operator. Install either dust bag or filter bag before using cleaner. Dust bag are usable many times repeatedly by
cleaning it out. Filter bag is a throw-away type. Throw away the entire filter bag without emptying when it has become full.
When the filter bag is already full, replace with new one. When the dust bag is already full, empty it. Continuous use with the filter bag/dust bag full results in reduced suction power.
NOTICE To prevent dust from getting into the motor

Make sure that the filter bag/dust bag is installed before use.
Do not use a broken or ripped bag otherwise the motor may be broken.
Do not fold the cardboard at its opening when installing the filter bag/dust bag.
The filter bag/dust bag for the cleaner is an important component for maintaining the appliance performance.
Using non-genuine filter bag/dust bag may cause smoke or ignition.
When the filter bag/dust bag is not installed in the cleaner, the front cover does not close completely.

Unlock the latch by lifting the bottom side. Push the grooved area to lift the front latching side. Pull the latch to open the lid. Insert the filter bag into the slit on the upper side of the room as illustrated. When using the dust bag, insert the brim of the dust bag into the slit. Align the hole of the filter bag with the hose cuff and push the cardboard portion to the end. Make sure that the rubber ring on the filter bag goes over the rim on the hose cuff.

OPERATION

Operators shall be adequately instructed on the use of the vacuum cleaner.
This vacuum cleaner is not suit-able for picking up hazardous dust. This cleaner is for dry use only. This cleaner is for indoor use only.

Cleaning the HEPA filter

Do not use the vacuum cleaner without a filter or continue to use dirty or dam-aged filter. Vacuumed dust or particles may be exhausted from the cleaner and they may cause respiratory disease to the operator. To keep optimum suction power and clean exhaust, clean the filter periodically. If enough suction power is not obtained even after the cleaning, replace the filter with new one.
To prevent the filter from being dam-aged, do not use following tools and similar items for cleaning :
Air duster
High pressure washer
Tools made of hard materials such as a metallic brush
Open the lid and take out the filter bag/dust bag. Release the hook on the filter and remove it from the vacuum cleaner body.
Beat the dust off from the filter. The filter can be washed with water. Rinse away the dust and particles on the filter every 1 or 2 month. After that, dry the filter completely in a shaded and well-ventilated place to prevent unpleasant odor or malfunctions.
To install the filter, insert the side without the hooks into the groove then push in the filter until the hooks are secured with a click.

Cleaning the dust bag

Regularly clean the dust bag with soap and water. Turn the dust bag inside out and remove the sticky dust. Wash lightly by hand and rinse well with water. Dry completely before installing to the vacuum cleaner. Wet dust bag lowers the vacuuming performance as well as the life of the motor.
