[. . . ] also wear a dust mask and thickly padded gloves. Prior to work starting, make sure that cutting accessory is fitted properly. Before starting work carefully check all screws for tightness. Due to vibration screws come loose and can cause serious breakdown or injury. [. . . ] In this case you have to remove the load. for longer disregard of the red LED it follows a self-contained of the machine. After discharge and reengagement one can drill again. When continuous overload is applied (despite the electronic device) a thermal protection will protect the motor. The machine disengages itself in this case and can be put into operation after waiting for cooling down (approx. ) The time needed to be able to restart the machine will be vary dependent on overheating of the coil and the ambient temperature. To speed up the cooling down of the machine let the machine after the restart run 1-2 min. Never drill without water supply due the spindle could be damaged. If there is water leakage between the water supply ring and the gearbox housing you have to change the water supply respectively replace the shaft seals by new and slight greasy shaft seals. These are available about dealers or manufacturer. The water supply (black plastic ring) can only remove by pull down. The mounting of the water supply occurs to push open till it snapped. Pay attention to the position of the dowel (for protection against twist) Do not damage the seal rings during the mounting. The machine has an external water supply through the work spindle. With the help of the water tap you can regulate the water quantity. In case of drilling "overhead" you have to exhaust the leak out water at the drill hole by suction ring and wet-vacuum cleaner for reasons of safety at work and reliability. For operator full protection this machine must only be used by wet drilling with fault current protection device. Therefore the DBM181 is standard equipped witch PRCD protection switch be used on a grounded socket. Due to it's design, the machine needs a minimum of care and maintenance. Nevertheless, you should always observe the following: Keep the electric tool clean Avoid any particle or part to penetrate inside the tool If the machine is defect let carry out a repair only through an authorized workshop. 2 Dry Drilling Only perform dry core-drilling on brickwork and soft lime or soft sand stones. We strongly recommend you to wear a face shield as well. [. . . ] The optimum cutting speed is between 2 and 5 m/s. Should core-bit jam or there is no progress made when drilling, check to ensure that there is sufficient amount of diamonds present in the surface of segments. If this is not the case, replace the core-bit. Safety Switch Check RCD (Residual Current Device) daily, following enclosed instructions. [. . . ]
