[. . . ] When working outside, the use of rubber gloves and non-slip shoes is recommended. If work the electric tool/machine is not in use, prior to cleaning and maintenance work and when changing a drill bit, saw blade or insert tools of any kind. before switching on that the key or adjusting tools have been removed. any parts are broken, whether all other parts work properly and are fitted correctly, and make sure that all other conditions which can influence operation and running of the electric tool/machine are as they should be. Damaged guards and protective devices and parts must be repaired properly by an authorized service workshop or replaced provided that nothing else is stated in the operating instructions. [. . . ] ers. ) Note: Drilling without dust removal could permanently damage or destroy the diamond core bit. The water swivel is connected by way of a Gardena coupling. The water supply valve () can be regulated using the index finger (). The flow of water is displayed by the flow indicator. Note: If wet-drilling core bits are allowed to run dry, they will become overheated, which could lead to destruction of the diamond segments. Insert the core bit into the chuck, possibly turning it slightly until the longitudinal groove can be felt to lock in place. to remove the core bit, first slide back the locking sleeve and then pull out the core bit. 17 Speed-change switch Important: Wet and dry-drilling core bits are designed for a drilling contact pressure of 250 N (25 kg). Insufficient pressure can lead to polishing of the segments and a reduction of drilling performance. 51343/3).

Caution: DD-BI-HCW core bits (hand held) must be used for drilling anchor holes!18 If the sealing ring supplied with the diamond core bit begins to leak, it must be replaced.

When the core bit is released, ensure that the core does not accidentally fall out of the bit. When drilling overhead, close the water supply valve and drain the core bit via the water supply hose before releasing it from the chuck. Important: First-time conversion of a dry-drilling machine (DD100-D, DD100-B) to a wet-drilling (DD100-W, DD100-M) can only be carried out by a Hilti service centre. 19 Safety precautions on the jobsite Preparations before beginning work Electrical safety The PRCD (DD100 wet drilling machine) fault interruptor protects the operator in case of faults in the insulation of the motor unit or supply cord (between the PRCD and the motor unit). This device also prevents the machine from restarting of its own accord when power returns after an interruption in the power supply. The earth/ground connection protects the operator from dangerously high voltages in case of drilling into live cables. The protective function of the ground fault interruptor must be checked at regular intervals in accordance with regulations issued by national authorities.
