Using the Bosch RH540S rotary hammer is straightforward. First, select the appropriate mode using the dual - mode selector depending on whether you need to drill or chisel. Adjust the speed using the variable speed dial according to the material you're working on. For example, use a lower speed for softer materials and a higher speed for harder ones. When using the Vario - Lock function, rotate the chisel to the desired position and lock it in place for a better working angle. As for safety, always wear safety goggles and gloves. Make sure the bit is properly installed before starting the tool. When the bit gets stuck, don't force it as the integral clutch will disengage the torque transmission. For maintenance, keep an eye on the service minder brushes. When they indicate that preventive maintenance is required, call a qualified service technician to replace the brushes and cord using the innovative service modules. Also, clean the tool regularly after use to keep it in good condition.
