Setting the torque
• The power tool has an adjustable clutch to set the required torque with the knob.
When correctly set, the power tool stops tightening at the set torque to prevent
the screw being over-tightened.
• The setting depends on the type and size of the screw and the type of material.
Always start with the lowest torque and increase the torque gradually for
the result you want.
Stepless speed control
• Excellent for screwdriving. The more you press the trigger switch,
the higher the rotation speed.
• The power tool has an electric brake which operates when you release
the trigger switch, so that the chuck stops quickly.
7. Use
• Choose the accessory you want to use (drill bit, etc), fit it to the chuck and
tighten the chuck.
• To start and stop the power tool, press and release the trigger switch.
