[Battery Charger] Charging CAUTION:

1) If the temperature of the battery pack

falls approximately below −10°C (14°F), charging will automatically stop to prevent degradation of the battery.

2) The ambient temperature range is

between 0°C (32°F) and 40°C (104°F). If the battery pack is used when the battery temperature is below 0°C (32°F), the tool may fail to function properly.

3) Use the charger at temperatures

between 0°C and 40°C, and charge the battery at a temperature similar to that of the battery itself. (There should be no more than a 15°C difference between the temperatures of the battery and the charging location.)

4) When charging a cool battery pack

(below 0°C (32°F)) in a warm place, leave the battery pack at the place and wait for more than one hour to warm up the battery to the level of the ambient temperature.

5) Cool down the charger when charging

more than two battery packs consecu- tively.

6) Do not insert your ngers into contact

hole, when holding charger or any other occasions.

7) Unplug the charger when not in use.

8) Store the charger between 0 and 40

degrees, and charge the battery pack at a temperature close to the storage temperature.

• If the battery pack is charged while at a temperature below 0 degrees, a full charge will give only around 50% of a normal charge. Commence charging after 1 hour or more at the prescribed temperature.

9) Do not charge in a poorly ventilated

10) Do not cover the battery pack or

charger with a cloth or the like while charging is in progress. NOTE: Your battery pack is not fully charged at the time of purchase. Be sure to charge the battery before use. How to charge

1. Plug the charger into the AC outlet.

NOTE: Sparks may be produced when the plug is inserted into the AC power supply, but this is not a problem in terms of safety.

2. Connect the battery pack rmly into the

charger. (1) Line up the alignment marks and place the battery onto the dock on the charger. NOTE: Not all battery packs display the alignment mark (Q) (on page 2). (2) Slide forward in the direction of the arrow. [Fig.10

3. During charging, the charging lamp will

be lit. When charging is completed, an internal electronic switch will automati- cally be triggered to prevent overcharg- ing.

• Charging will not start if the battery pack is hot (for example, immediately after heavy-duty operation). The orange standby lamp will be ashing until the battery cools down. Charging will then begin automatically.- 17 -

4. The charge lamp (green) will ash

slowly once the battery is approximate- ly 80% charged.

5. When charging is completed, the

charging lamp in green color will turn off.

6. If the temperature of the battery pack is

0°C or less, charging takes longer to fully charge the battery pack than the standard charging time. Even when the battery is fully charged, it will have approximately 50% of the power of a fully charged battery at normal operating temperature.

7. Consult an authorized dealer if the

charging lamp (green) does not turn off.

8. If a fully charged battery pack is insert-

ed into the charger again, the charging lamp lights up. After several minutes, the charging lamp in green color will turn off.

ACCESSORIES CAUTION: To prevent the risk of injury, only use accessory or attachment for its stated purpose. NOTE: If you need any assistance for more details regarding these accessories, ask your local service center. Chisel Attachment

1. If there isn’t enough force pushing

down on the bit, the hammer may not be able to blow in hammering mode. This is to prevent the hammering mode from operating with no load. Press down harder on the bit to engage the hammer and cause it to blow. Always be sure to press down with enough force when working.

2. In winter or in other situations where

the temperature of the unit is low (5°C or below), the blow of the hammering mode may be weaker than normal at the beginning stage. This is because the grease becomes stiffer in low temperatures, increasing friction. If this should happen, operating hammering mode with no load for approximately 30 seconds and repeat this 3 times. This will restore its blowing power.- 21 -
