aid a drill drift.
WARNING!
Do not unfit the quick-action drill chuck until the drilling machine has been disconnected
from the power supply.
Disconnect the drilling machine from electrical power supply.
Move the drill sleeve down.
Turn the drilling spindle so that the opening at the drilling spindle sleeve coincides with the
opening at the drilling spindle.
Loosen the taper mandrel of the quick-action drill chuck with the help of a drill drift.
4.7.2 Assembly quick- action drill chuck
The quick-action drill chuck is secured
through a form-fit union (pulling heel)

drel of the tool or the quick-action drill chuck.
Press the taper mandrel into the drilling spindle.

Cooling
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 deliv-
ery volume, you can cool by means of a spray gun or a washing bottle.
ATTENTION!
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.
