It can directly be attached to the connection (F) on the dust hood.
Wet cutting:
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 (N).
Always make sure that the machine only runs with enough clear water as
the seals get damaged when the machine is running dry. The water feed
can be regulated via a miniature ball valve.
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.
Cutting:
Hold the tool firmly with the right hand on the switch handle and the left hand on
the additional handle. Place the front role (E) on the workpiece to be cut without
allowing the diamond disc to come into contact with it. Then activate the tool
and wait until the diamond disc has reached full speed. Dip into the material.
Now slide the tool in a flat and even manner across the surface of the
workpiece until the cut is completed.
To achieve a clean cut, maintain a straight cutting line and a steady speed of
advance.
The machine must always work in an up-grinding motion. Otherwise, the danger
exists of it being pushed uncontrolled out of the cut.
For cutting stone, it is best to use a diamond cutting disc.
Information for diamond cutting discs:
Noticeable decreasing work progress and circular sparking are indications of a
blunt diamond cutting disc. Briefly cutting into abrasive material (e. g. lime-sand
brick or the EIBENSTOCK-diamond-sharpening-stone) can re-sharpen the disc
again.
Never use a cutting disc for roughing.
Do not strain the machine so heavily that it comes to a standstill.
Information on Structures:
Slots in structural walls are subject to the Standard DIN 1053 Part 1, or country-
specific regulations. These regulations are to be observed under all circumstanc
es. Before beginning work, consult the responsible structural engineer, architect
or the construction supervisor.
Overload Protection
To protect the user and motor and drill bit, the ETR 400 P are equipped with a
mechanical, electrical and thermal overload protection.
Electrical: To warn the user against overstressing the tool by applying to
high an advance force, the handle includes a LED (L) as a
overload indicator. It does not light during idle run or at normal
load. At overload, it lights red. In that case the tool most be
stress-relieved. In case of longer non-observation of the rad
