How to use

Before use, fit a charged battery compatible with the kit and ensure the battery is correctly inserted and locked. For drilling in concrete, select an appropriate SDS or compatible drill bit, set the rotary hammer to the drilling or hammer mode as required, mark the drilling point and start at low speed to position the bit, then apply steady pressure while drilling. For chiselling, switch to chisel mode and use light, controlled impacts to remove material. For grinding or cutting, mount a suitable 125 mm disc with M14 thread on the angle grinder, secure the guard and auxiliary handle, start the tool and bring it to operating speed before contacting the work surface. Always check tool settings and accessories before each operation.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and dust mask when working with rotary hammers and grinders. Select drill bits and discs rated for the material and application. Allow tools and batteries to cool between heavy-duty cycles and follow manufacturer instructions for battery charging and storage to maintain performance and service life.
