Cooling
WARNING!
Ejection and overflowing of coolants and lubricants. Make sure you do not get the
cooling lubricants on the floor. Spilled on the floor cooling agents must be removed
immediately.
The friction generated during rotation can cause the edge of the tool to become very hot.
The tool should be cooled during the drilling process. Cooling the tool with a suitable
cooling lubricant ensures better working results and a longer edge life of the tools.
This is best realised by a separate cooling equipment. If there is no cooling equipment included
in the delivery volume, you can cool by means of a spray gun or a washing bottle.

Adjust the flow using the shut-off and dosing tap.
ATTENTION!
Failure of the pump in case of dry running.
The pump is lubricated by the cooling agent. Do not start up the pump without cooling
agent.
CAUTION!
Danger of injury due to brushes getting caught or pulled in.
Use a spray gun or a washing bottle for cooling.
INFORMATION
Use a water-soluble and non-pollutant drilling 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 any lubricants and coolants.
Follow the manufacturer’s disposal instructions.
