The EBM 352/3 is made in protection class I. In order to protect the
operator, the machine can only be run with a GFCI. For this reason, the
machine is standard equipped with a PRCD switch integrated in the cord
which allows to connect the unit directly with a grounded socket.

pressing the TEST button.
First, check the correspondence of voltage and frequency and compare it
with the data mentioned on the identification plate. Voltage differences
from + 6 % to – 10 % are allowed.
Use only 3-wire extension cable with protecting conductor and a sufficient
cross-section (min. 2.5 mm
lead to excessive power loss and to overheating of machine and cable.
The machine is equipped with a start-up speed limiter to prevent fast
expulsion fuses from unindented responding.
Water Connection
If the drill bit is not cooled enough with water, the diamond segments
could 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 exceed 3 bar!
Make sure that the segments are well cooled. If the drilling water is
milky, the segments are well cooled.
Overhead-drilling only with water collection ring.
In case of frost warning, drain the water system.
