  For optimum battery life, store the Li-ion battery pack following use without charging it   

  Do no charge battery when ambient temperature is below 0ºC (32ºF) or above 40ºC (104ºF). If 

the battery pack is used when the battery temperature is below 0ºC (32ºF), the tool may fail to 
function properly.  

  This battery pack has the built-

in “Battery Fuel Gauge.” Press the gauge button (1) to check the 

fuel condition of the battery pack. If you notice the battery fuel gauge only left with one red light 
that means the battery is running low. 

  Charge the battery pack immediately, or the power of the tool may not reach to your desired 

torque.  

 

Battery Pack Life  

 

The rechargeable batteries have a limited life. If the operation time becomes extremely short after 
recharging, replace the battery pack with a new one.  

 

Battery Recycling 

The batteries must be recycled or disposed properly

.

 

 

Charging The Battery  

  

  When charging a cool battery pack below 0ºC (32ºF)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. Otherwise battery pack may not be fully charged.  

  Cool down the charger when charging more than two battery packs consecutively.  

  Do not insert your fingers/ nails into contact hole, when holding charger or any other occasions. 

  

  Place charger in a relatively cool and well-ventilated area.  

 

  Plug charger into the AC outlet. CAUTION: Ensure that the power source to be utilized 

conforms to the power requirement specified on the product nameplate.  

 

Turn the battery up-side-down and slide the battery into charger while keeping 
the alignment marks line up. Slide the forward in the direction of the arrow. Do 
not force battery as it should slide easily into place with nominal force. Any 
difficulty doing so would indicate an incorrect alignment.   

 
 

If the power lamp (red) does not light immediately or goes out soon after the 
charger is plugged in, contact our repair center.  

 

  During charging, the charging lamp (green) will start flashing. When charging is completed, an 

internal electronic switch will automatically be triggered to prevent overcharging.  

  Charging will not start if the battery pack is warm. For example, immediately after heavy-duty 

operation. The yellow standby lamp will be flashing until the battery cools down.  

  If the temperature of the battery pack is 0º 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 operation temperature. 

 

 

O

nce the battery is fully charged, the green lamp will be lit to indicate the gone into a trickle 

charge mode.  

 

                  

Li-ion Battery Pack 

 

Your battery pack is not fully charged at the time of purchase.
