Coolant equipment
WARNING!
Discharge and overflow of cooling lubricants and lubricants Make sure you do not get
the cooling lubricants on the floor. Spilled on the floor cooling agents must be removed
immediately.
Due to friction heat caused by the rotation movement high temperatures are generated on the
cutting edge of the tool.
Cool down the tool while drilling. In this way you attain better working results and a longer dura-
bility of the tools.
Adjust the flow using the shut-off and dosing tap.
ATTENTION!
Destruction of the pump due dry running.
The pump is lubricated by the cooling agent. Do not operate the pump without coolant.
INFORMATION
Use a water-soluble and non-pollutant emulsion as a cooling agent.This can be acquired from
authorised distributors.
Make sure that the cooling agent is being collected.
Respect the environment when disposing of lubricants and coolants.
Follow the manufacturer’s disposal instructions.
