"A mode (assist mode)" is an easy-to-use mode for

"T" is a special mode for fastening self drilling screws.
In this mode, the tool starts to drive a screw with faster

impacts in medium force grade.
You can change the impact force within approximately
one minute after releasing the switch trigger.
