15.2.8 Switching on Cooling system
Use a water-soluble, environmentally friendly drilling emulsion as coolant,
as it is available from specialist retailers. Ensure that the coolant is
collected again and that it is disposed of in an environmentally friendly
manner (aleways follow the manufacturer's instructions!).
The rotary motion generates frictional heat at the cutting edge of the tool. The tool should therefore
be cooled during drilling. This will result in a better working result and a longer tool life.
Cooling system is switched on by setting the switch for the coolant pump (7) to the O
and opening the valve on the blue side feed line.
