[. . . ] Safety precautions Caution: The following fundamental safety precautions must always be observed when using electric tools/machines as protection against electric shock, the risk of injury and fire hazards. Please read and take note of these precautions before you use the tool/machine. 7 Always use the right electric tool/machine for the job. Don't use underpowered tools/machines or attachments for heavier duty jobs. Don't use electric tools/ machines for work and purposes for which they are not intended, e. g. [. . . ] After push- necessary. Press the vacuum cleaner hose firming in the insert tool as far as it will go, tight- ly into the extration head connection (). (See page 23 for adaptor for other vacuum cleanen the chuck using the key provided. 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. Push the chuck rotation-prevention pin into the opening provided. 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. Polished/blunt core bits can be resharpened e. g. using the Hilti sharpening plate (item no. 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.
