Possible misuse
• This product is not suitable for working on hazardous materials.
• This product is not suitable for working in a damp environment.
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.
Motor protection system
The tool is equipped with a motor protection system. The system monitors current input and motor
temperature and thus prevents the tool from overheating.
If the motor is overloaded through application of excessive working pressure, the power tool's
performance drops noticeably or it may stall completely.
If the power tool stalls or slows significantly due to overloading, release the pressure applied to the
tool and then allow it to run under no load for approx. 30 seconds.
