NOTE
The recharging time may vary according to temperature and power source voltage.
CAUTION
When the battery charger has been continuously used, the battery charger will be heated, thus constituting the cause of the failures. Once the charging has been completed, give  15 minutes rest until the next charging. 4. Disconnect the charger’s power cord from the receptacle.

5. Hold the charger fi 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 fi rst and second time. This is a temporary phenomenon, and the 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.

CAUTION

• If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights for 1 second, but does not light for 0.5 seconds (off for 0.5 seconds). In such a case, fi first let the battery cool, then start charging.
• When the pilot lamp fl ickers (at 0.2-second intervals), check for and take out any foreign objects in the charger’s battery connector. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.
• Since the built-in microcomputer takes about 3 seconds to confi rm that the battery being charged with the charger is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

MOUNTING AND OPERATION

*1 When the brightness reaches the maximum (4000 lm) or the minimum (700 lm), the light briefl y blinks twice.

*2 NOTE
When using a tripod, ensure that it is stable so that it does not fall over.

When the remaining battery becomes low, the light briefl y blinks about once every 3 minutes.
As the remaining battery indicator shows somewhat diff erently depending on ambient temperature and battery characteristics, read it as a reference.

NOTE
○ When using a Multi-volt battery, please refer to the indicator lamp on the battery for the battery’s remaining power.
○ Do not give a strong shock to the panel or break it. It may lead to trouble. *4
NOTE
○ If the remaining battery becomes low, USB output is automatically stopped, and the work light cannot charge USB devices.
○ The charging time diff ers depending on the type of USB the device being used.
○ Do not use it for any purpose other than charging a USB device.
(Refer to “USB DEVICE CONNECTION PRECAUTIONS”.)

MAINTENANCE AND INSPECTION

WARNING
When not using the work light for a long time, performing maintenance on it, inspecting it, or storing it, be sure to turn OFF the switch and pull out the battery.

1. 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 could result in serious hazards.

2. Inspection of terminals (tool and battery) Check to make sure that swarf and dust have not been collected on the terminals.
   On occasion check prior, during, and after the operation.
   CAUTION
   Remove any swarf or dust which may have collected on the terminals.
   Failure to do so may result in malfunction.

3. Cleaning on the outside
   When the cordless work light is stained, wipe with a soft dry cloth or a cloth moistened with soapy water.
   Do not use chloric solvents, gasoline or paint thinner, for they melt plastics.

4. Storage
   Store the cordless work light and the battery in a place in which the temperature is less than 40°C and out of reach of children.

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, signifi cantly reducing battery usage time or rendering the batteries incapable of holding a charge.
However, signifi cantly reduced battery usage time may be recovered by repeatedly charging and using the batteries two to fi ve times.
If the battery usage time is extremely short despite repeated charging and use, consider the batteries dead and purchase new batteries.
