Safety
ips and recommendation
It is necessary to observe the safety notes written in
these operating instructions in order to reduce the risk of
personal injuries and damages to property.
2.2 Responsibility of the operator
The operator is the person who operates the machine
himself for commercial purposes or who makes it availa-
ble to a third party for use or application and who bears
the legal product responsibility for the protection of the
user, personnel or third parties during operation.
Obligations of the Operator:
If the machine is used in the commercial sector, the ope-
rator of the machine is subject to the legal obligations for
occupational safety. Therefore, the safety instructions in
these operating instructions as well as the safety, acci-
dent prevention and environmental protection regulati-
ons valid for the area of application of the machine must
be observed. The following applies in particular:
- The operator must inform himself about the appli-
cable occupational health and safety regulations
and determine additional hazards in a hazard as-
sessment that result from the special working con-
ditions at the place of use of the machine. He must
implement these in the form of operating instructi-
ons for the operation of the machine.
- During the entire period of use of the machine, the
operator must check whether the operating instruc-
tions he has drawn up correspond to the current
status of the regulations and, if necessary, adapt
them.
- The operator must clearly regulate and define the
responsibilities for installation, operation, trouble-
shooting, maintenance and cleaning.
- The operator must ensure that all persons handling
the machine have read and understood these in-
structions. In addition, he must train the personnel
at regular intervals and inform them about the dan-
gers.
- The operator must provide the personnel with the
required protective equipment and instruct them to
wear the required protective equipment.
Furthermore, the operator is responsible for ensuring
that the machine is always in technically perfect condi-
tion. Therefore, the following applies:
- The operator must ensure that the maintenance in-
tervals described in this manual are observed.
- The operator must have all safety devices checked
regularly for functionality and completeness.

It must be ensured that the power connection has the
same characteristics (voltage, mains frequency) as the
motor.
8 Installation and Commissioning
9 Service
Always follow the safety instructions and follow the rele-
vant regulations.
Before switching on the device, the electrode holder
must always be in the supply channel.
9.1 Operation
Prior to commissioning, make sure that the mains
voltage and mains frequency stated on the rating plate
match the data of your mains supply. The connection is
only permitted on sockets with protective contact.
The device is equipped with a clamping sleeve for cer-
tain electrode diameters. It is possible that another collet
must be used for a different diameter. The device must
then be converted accordingly.
tep 1: Turn the rotating body (A) to the required angular
position by referring to the angle indicator (C).
et the grinding angle according to the required
grinding effect and tighten the fastening knob (B,
Fig.4) on both sides.

electrode (Item 2, Fig. 2, the lock knob is on the
rotary body and the tungsten electrode tip is bet-
ween the two lines of the longitudinal position
setting block).
tep 3: Turn the upper (Item 2, Fig. 2) and lower adjust-
ment knob to the highest position.
DANGER!
Danger of electrocution!
Work on the electrical connection may only be carried
out by qualified electricians.
CAU ION!
