3.5 ATC
The product is equipped with the ATC (Active Torque Control) quick-acting
electronic cut-out.
If the accessory tool sticks or stalls, the product will suddenly pivot about
its own axis in the opposite direction. ATC detects this sudden pivoting
movement of the product and switches the product off immediately.
For ATC to function correctly, the product must be free to pivot.
After an ATC cut-out, switch the product off and then on again.
