4. OPERATION
Operation
The impact wrench is driven by an electric motor
via a gear and impact mechanism.
The impact mechanism starts when the screwed
connection runs tight and load is put on the motor.
The mechanism converts the power of the motor
to steady rotary impacts.
Always observe the safety instructions
and applicable regulations.

Firmly hold the machine and push the bit with even
pressure into the workpiece. Do not force the
machine.
Use only bits that do not yet show any signs of
wear. Worn bits have a negative effect on the
efficiency of the machine.
