The hammering force can be changed in three steps:
hard, medium and soft.
This allows a tightening suitable to the work.
Every time the hammering force button
the number of blows changes in three steps.
For approximately one minute after releasing the switch
trigger, the hammering force can be changed.
NOTE:
• When all lamps on the switch panel go out, the tool is
turned off to save the battery power. The hammer force
grade can be checked by pulling the switch trigger to
the extent that the tool does not operate.
• During the operation of switch trigger, the hammer
force grade cannot be changed.
Empty signal for remaining battery capacity (Fig. 7)
Pulling the trigger switch when the remaining battery
capacity becomes very low makes LED indicator lights
up.
If the tool is used continuously with the LED indicator
lighting up and the battery power is almost used up, the
LED indicator will flicker and the tool itself will stop.
Please refer to the following table for the LED indicator
status and the remaining battery capacity.

• If the bit is not inserted deep enough into the sleeve,
the sleeve will not return to its original position and the
bit will not be secured. In this case, try re-inserting the
bit according to the instructions above.
• When it is difficult to insert the bit, pull the sleeve and
insert it into the sleeve as far as it will go.
• After inserting the bit, make sure that it is firmly
secured. If it comes out, do not use it.
Hook (Fig. 11)
The hook is convenient for temporarily hanging the tool.
