Safety Instructions
Always wear appropriate personal protective equipment, including ear protection, eye protection, a dust mask, and safety gloves. Ensure the work area is clean and well-lit. Never operate the tool in explosive atmospheres. Always check for hidden electrical, gas, or water lines before drilling. Ensure the tool is switched off before connecting to the power supply.
Operation and Setup
To set up, attach the support handle by loosening the collar and sliding it over the flange. Adjust the depth stop to the desired drilling depth. To fit accessories, clean the shaft, apply a small amount of grease, insert it into the SDS chuck, and turn it to lock. Use the selectors to choose between drilling, hammer drilling, or chiseling modes. Never operate the selectors while the tool is running.
