Fastening to a rig
After each installation all screws and bolts, handles and other components for
affixing the apparatus must be carefully and firmly replaced for safety's sake.
The diamond motor must be attached to a stand using an intermediary plate and 4
screws (the 4 screws and the intermediary plate come with the stand).
Water supply
Connect the speed coupler, which you have first connected to the hose, to the water-
supply tap (8). In order to avoid leakage, check that everything is well connected.
SPIT provides a water catchment container as an accessory. Ensure, when not
using this container, that the cable and the PRCD cannot come into contact with
either water spray or flowing water. Whilst drilling in an upward direction, you
must use a water catchment container. It is forbidden to drill in an upward
direction without such a system.
Insufficient water supply, or none at all, even during short periods, can result in damage
to one or more segments of the bit.
The purpose of the water is to:
• Cool the segments during drilling
• Dispose of the mixture of drilled substance and water and keep the drilling surface
clean. If the drilled substance and water mixture stays around the drilled hole, then
the water supply is insufficient
• A correct regulation of the water supply ensures that the segments drill properly
• If you encounter reinforced sections, increase the water supply in order to dispose
of the metal pieces that can cause the segments to wear
