How to use

Select an appropriate SDS Plus drill bit for the material and secure it in the chuck until it locks. Set the perforator to the required mode (rotary with impact for concrete, rotary only for wood or metal where applicable) and mark the drilling position. Hold the tool with both hands, apply steady pressure without forcing the bit, and start drilling at low speed to establish the hole, then increase speed as needed. For chiselling tasks, use the appropriate chisel accessory and a non-dominant hand on the auxiliary handle to control direction and force. After use, release the bit, clean debris from the chuck area and store the tool in a dry place.

Usage recommendations

Use personal protective equipment such as safety goggles, hearing protection and dust mask when drilling concrete or masonry. For prolonged drilling sessions, allow periodic cooling intervals and inspect drill bits for wear to maintain performance. Match drill bit size and type to the task and material to avoid overloading the motor and to achieve accurate hole dimensions.
