How to Adjust Soft Start Setting

There are 3 different time settings for the Soft Start mode which are (0.2,
0.4 & 0.6 seconds). The default setting is OFF.

1. Press and hold the Soft Start button for 2 seconds.
2. Two LEDs will display colors that show the current soft start 

selection of the brushless screwdriver.

3. Press Soft Start button until the target time is selected.
4. By starting the screwdriver, the selected soft start setting is saved 

automatically.

The Soft Start button is “wrap around” button meaning you can toggle through the settings continuously by pressing the button 

(OFF - 0.2s-0.4s-0.6s).
