EIBENSTOCK ETR 400.2 P Notice Originale page 25

Cutting:
Hold the tool firmly with the right hand on the switch handle and the left hand on
the additional handle. Activate the tool and wait until the diamond disc has
reached full speed. Dip slowly into the material. Now slide the cutting system 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 400.2 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 (J) 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
indication, the electronics will independently switch the tool off.
After relieving be switching the tool off and on, the work can be
continued as normal.
Thermal: In case of permanent overload, a thermocouple protects the
motor against destruction. Here also, the user is warned by the
overload indicator. Shortly before the maximum temperature is
reached, the indicator flashes red.
In that case, the tool switches off and can only be restarted
after a certain cooling-down period (approx. 2 minutes). The
overload indicator flashes until the machine has cooled
sufficiently and can be used again. The cooling-down time
depends on the temperature of the motor winding and ambient
temperature.
