LED indication

The LED will be lit when the switch is 
pressed.The tool and battery are equipped 
with automatic power-off protection system. 
The LED flickers for 3 seconds and then 
goes off, indicating that the protection 
system works. At this time, the system 
automatically cuts off the power supply 
to prolong the battery life. The following 
situations may trigger automatic power-off 
protection:

• Overload: Tools are overloaded when 

they are running, the current is too 

high. 

In this case, release the switch, stop the 

operation leading to tool overload, and restart 

the switch.

• Overheat: 

In the case above, if the tool 

is not started, the tool and battery may be 

overheated. In this case, cool the tool and 

battery pack before starting the switch again.

• Low voltage: The tool does not work 

when the remaining capacity is too 

low. 

In this case, dismantle and replace the 

battery pack.

Warning:

 Make sure the reversing 

lever is on the left or right, press the 

switch and the LED light comes on.

FAQS
1. Why has the switch been pressed and the 

machine does not work?

There is a reversing lever at the top of the switch. When it is 

in the middle position, the machine will lock the start-stop 

switch. Put it where it needs to be turned and press the 

button, the machine will start to rotate.

2. Why does the electric drill stop running before 

the screw is tightened?

At this time, please adjust the torsion adjustment ring 

between the frame and the chuck. The torsion correspond-

ing to position 1 is the smallest, and that corresponding to 

position 20 is the largest. Position    specially for drilling 

holes This problem can be solved by adjusting the torsion 

adjustment ring to a higher level.

3. Why is the working time of the same battery 

pack sometimes long and sometimes short?

As mentioned above, if a battery pack is left unused for too 

long, its working time will be shortened. Such situation will 

be improved after charging and using for several times. Un-

der doing heavy work, such as screwing big screw into hard 

wood, the battery power will be consumed very fast. Do not 

charge in the environment below 0 or above  40°C, which 

will also affect the performance of the battery pack.
