Completely unscrew the four screws. Rotate the
machine head carefully, without removing it
from the housing, to the new position. Screw in
and tighten the four screws again.
Dust/Chip Extraction
Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Operation
Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
When operating the machine with power from
mobile generators that do not have sufficient re-
serve capacity or are not equipped with suitable
voltage control with starting current amplifica-
tion, loss of performance or untypical behavior
can occur upon switching on.
Please observe the suitability of the power gen-
erator being used, particularly with regard to
the mains voltage and frequency.

Switching On and Off
To start the power tool, push the On/Off switch
4 forwards.
To lock the On/Off switch 4, press the On/Off
switch 4 down at the front until it latches.
To switch off the power tool, release the On/Off
switch 4 or, if it is locked, briefly push down the
back of the On/Off switch 4 and then release it.
Check grinding tools before using. The
grinding tool must be mounted properly
and be able to move freely. Carry out a test
run for at least one minute with no load. Do
not use damaged, out-of-centre or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.
Kickback stop
In case of a sudden drop in speed,
e.g., caused by a jammed disc
while cutting, the power supply to
the motor is electronically inter-
rupted.
To restart the operation, switch the On/Off
switch 4 to the Off position and start the ma-
chine again.
Restarting Protection
The restarting protection feature prevents un-
controlled restarting of the machine after an in-
terruption in the power supply.
To restart the operation, switch the On/Off switch
4 to the Off position and start the machine again.
Reduced starting current
The electronic reduced starting current limits the
power consumption when switching the tool on
and enables operation from a 13 ampere fuse.
Constant Electronic Control
Constant electronic control holds the speed
constant at no-load and under load, and ensures
uniform working performance.
