EIBENSTOCK END 1550 P Notice Originale page 22

A permanent use with reduced speed can cause an overload because the
motor then gets less cooling air and therefore the machine will be
overheated much faster. A thermal switch-off can be released!
Water Supply
If the drill bit is not cooled enough with water, the diamond segments heat
up and consequently get damaged and weakened. For this reason, always
make sure that the cooling system is not blocked.
In order 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 be more than 3 bar.
Make sure that the segments are well cooled. If the drilling water is
clear, the segments are well cooled.
Overhead-drilling only with water collection ring.
In case of frost warning, drain the water system.
The END 1550 P is equipped with a G½" internal thread
Drill bits with the following connections can be used with the adapters
included in delivery:

Pay attention that the diamond segments have enough relief cut toward the
drill bit body.
Drill Bit Changing
Attention!
When you use or sharpen the machine, it might heat up enormously.
You could burn your hands or get cut or ripped by the segments.
Therefore, always use protective gloves when changing the drill bit.
The drill spindle of the END 1550 P has a right-hand thread.
To hold on spindle always use an open-end wrench SW 32.
Never remove the drill bit with impacts because this way the machine will
be damaged.With some waterproof grease which is put on the drill bit
thread you can remove the drill bit easier.
