Changing the impact force
You can change the impact force in five steps: 4 (max), 3 (hard), 2 (medium), 1 (soft) and T mode.
This allows a tightening suitable to the work.
“T” is a special mode for fastening self-drilling screws. This mode helps to prevent the screws from over-tightening. It
also accomplishes quick operation and good finish at the same time. The tool drives a screw with high-speed rotation
and stops soon after the tool starts to impact.
The level of impact force changes every time you press the button
or button .
You can change the impact force within approximately one minute after releasing the switch trigger.
NOTE:
You can extend the time to change the impact force approximately one minute if you press the button
or
button .
