EIBENSTOCK EDS 181 Notice Originale page 22

If the diamond cutting disc is not adequately cooled with water, the diamond
part can heat up, which can damage and weaken it. You should therefore
always ensure that the water supply is not clogged.
To supply the machine with water please proceed as follows:
Connect the tool to the water supply system or a water pressure vessel
using the GARDENA connector.
Always make sure that the machine only runs with enough clear water
as the seals get damaged when the machine is running dry.
Attention! The maximum water pressure should not exceed 3 bar!
Make sure that the segments are well cooled. If the drilling water is
clear, the segments are well cooled.
In case of frost warning, drain the water system.
Changing the Diamond Cutting Discs
Attention!
The Cutting discs, spacer discs and the flange nut might heat up
enormously during operation. You could burn your hands or get cut or
ripped by the segments.
Therefore, always use protective gloves when changing the grinding
wheel.
Before any work on the tool, disconnect the plug from the mains!
Wet cutting
Fasten the water connection to the connecting
piece on the protective hood.
To do this, pull the anchorage ring when
inserting the connection, and turn the water
connection until the anchorage clicks into the
corresponding hole.
Press the spindle lock button to lock the
work spindle .
Actuate the spindle lock button only
when the work spindle is at a standstill.
Otherwise, the machine may become
damaged.
