Impact Wrench
Using The LED Light
Before operation, the LED light 
will be activated when the On/Off 
switch is slightly depressed, and will 
automatically turn off 20 seconds 
after the On/Off switch is released.
The tool and battery are equipped 
with a protection system. When 
the LED Light is quickly flashing 3 
seconds 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 
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 are overheated. In 
this situation, let the Tool and Battery 
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.
WARNING: 
To turn on the light, press the 
On/Off switch and make sure the 
Forward/Reverse Rotation Control is 
on right/left position.

TROUBLE SHOOTING
1. I CAN NOT FIT THE BATTERY INTO THE 
BATTERY CHARGER. WHY?
The battery can be inserted into the charger only in 
one direction. Turn the battery around until it can 
be inserted into the slot, the red LED Light should 
turn on when the battery is charging.
2. REASONS FOR DIFFERENT BATTERY PACK 
WORKING TIMES
Charging time problems, as above, and having 
not used a Battery Pack for a prolonged time will 
reduce the Battery Pack working time. This can 
be corrected after several charge and discharge 
operations by charging & working with your drill. 
Heavy working conditions such as large screws 
into hard wood will use up the Battery Pack energy 
faster than lighter working conditions. Do not 
re-charge your Battery Pack below 0
o
C and above 
30
o
C as this will affect performance.
MAINTENANCE
Remove the battery pack from the machine 
before carrying out any adjustment, 
servicing or maintenance.
Your power tool requires no additional lubrication 
or maintenance. There are no user serviceable 
parts in your power tool. Never use water or 
chemical cleaners to clean your power tool. Wipe 
clean with a dry cloth. Always store your power 
tool in a dry place. Keep the motor ventilation 
slots clean. Keep all working controls free of 
dust. Occasionally you may see sparks through 
the ventilation slots. This is normal and will not 
damage your power tool. 
For Battery tools
The ambient temperature range for the use and 
storage of tool and battery is 0
