• Disconnect the charger's power cord from the receptacle.

• Hold the charger firmly and pull out the battery.

NOTE

Be sure to pull out the battery from the charger after use, and then keep it.

Regarding electric discharge in case of new batteries, etc.

As the internal chemical substance of new batteries and batteries that have not been used for an extended period is not activated, the electric discharge might be low when using them the first and second time. This is a temporary phenomenon, and normal time required for recharging will be restored by recharging the batteries 2–3 times.

How to make the batteries perform longer.

(1) Recharge the batteries before they become completely exhausted.

When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.

(2) Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

MAINTENANCE AND INSPECTION

WARNING

Be sure to turned off the switch and remove the battery before maintenance and inspection.

1. Cleaning the filter

If the vacuuming efficiency is poor even when the dust case has been emptied, remove the filter and wash it in cold or warm water. (The water should not be hot to the touch.)

After washing, dry out of direct sunlight. (Fig. 25-a)

Alternatively, blow off any debris attached to the filter from the inside toward the outside with an air gun or something similar. (Fig. 25-b)

NOTE

○ Do not wash the filter in a washing machine.
○ Do not wash the filter in hot water or dry it by fire.
○ Do not use an air gun or similar tool to clean the filter, fan filter or the appliance itself.

(Fig. 25-c)

Doing so could push dirt into the appliance and cause malfunction.

3. Inspecting the flooring nozzle

Inspect the flooring nozzle to confirm that its blade is not dislodged. If the blade is dislodged, press it in until it catches on the projection.

Using with the blade dislodged may cause stains.

When replacing the blade, insert it starting from the notch in the rail, and thread it along the groove. Ensure there is no sagging throughout. (Fig. 27)

Fig. 27

4. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loose, retighten them immediately. Failure to do so may result in serious hazard.

5. Maintenance of the motor

The motor unit winding is the very "heart" of the power tool.

Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

English

NOTE

Regularly idle the motor to clean out dirt and dust.

Damage may result if dirt or dust collects in the motor.

1. Inspection of terminals (tool and battery)

Check to make sure that swarf and dust have not collected on the terminals.

On occasion check prior, during and after operation.

CAUTION

Remove any swarf or dust which may have collected on the terminals. Failure to do so may result in malfunction.

1. Cleaning of the outside

When the tool is stained, wipe with a soft dry cloth or a cloth moistened with soapy water.

Do not use chloric solvents, gasoline or paint thinner, as they melt plastics.

1. Storage

Store the cordless cleaner in a place in which the temperature is less than 50^ C, and out of reach of children.

When storing the appliance in a vertical position, hook the strap to a hanger.

NOTE

Do not store in a location where children can easily reach or take out the appliance.
Do not store in a damp location or in an area exposed to rainfall.
Do not store in direct sunlight or in a location where temperatures may suddenly change.
Do not store in a location with volatile materials that could ignite or explode.
Do not stand the appliance against a wall without using the strap to fix it in place.

(Fig. 28) Failure to do so may result in damage from a fall.

NOTE

Storing Lithium-ion Batteries

Make sure the lithium-ion batteries have been fully charged before storing them.

Prolonged storage (3 months or more) of batteries with a low charge may result in performance deterioration, significantly reducing battery usage time or rendering the batteries incapable of holding a charge.

However, significantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to five times.

If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.

CAUTION

In the operation and maintenance of appliances, the safety regulations and standards prescribed in each country must be observed.
