OPERATING THE ON/OFF

WARNING: Do not

low speed because excess heat 
will be produced internally.
See Fig. F
LED LIGHT INDICATOR  (See Fig. F)
To turn on the light, press the on/off switch and make 
sure the forward/reverse rotation control is on right/
left position. When you release the on/off switch, the 
light will be off. 
LED lighting increases visibility-great for dark or 
enclosed area. LED is also a battery capacity indicator. 
It will flash when power gets low.
The tool and battery pack are equipped with a 
protection system. When the LED Light is quickly 
flashing and turn off, the system will automatically 
cut off power to the tool to extend battery life. The 
tool will automatically stop during operation if the 
tool and/or battery pack are placed under one of the 
following conditions:
• Overloaded: The tool is operated in a manner that 
causes it to draw an abnormally high current. In this 
situation, release the Trigger Switch on the tool and 
stop the application that caused the tool to become 
overloaded. Then pull the Trigger Switch again to 
restart.
• Overheated: Under the condition above, if the 
tool does not start, the Tool and Battery Pack are 
overheated. In this situation, let the Tool and Battery 
Pack cool before pulling the Trigger Switch again.
• Low battery voltage: The remaining Battery 
capacity is too low and the tool will not operate. In 
this situation, remove and recharge the Battery Pack.
PROBLEM SOLUTION
1. WHY DOES THE DRILL NOT TURN ON WHEN 
YOU PRESS THE SWITCH?
The Forward and Reverse Switch, which is on top of 
the trigger, is positioned in the lock function. Unlock 
the Forward and Reverse Switch putting it into the 
required rotation position. Push the trigger and the 
drill will start to rotate (See Fig. C1, C2, C3)
