Approved Grinding Tools
All grinding tools mentioned in these operating instructions
can be used.
The permissible speed [min
-1
] or the circumferential speed
[m/s] of the grinding tools used must at least match the values
given in the table.
Therefore, observe the permissible
rotational/circumferen-
tial speed
on the label of the grinding tool.
Rotating the Machine Head
Before any work on the machine itself, pull the mains
plug.
The machine head can be
rotated with respect to
the machine housing in
90° steps. In this manner,
the On/Off switch can be
brought into a more con-
venient position for spe-
cial working situations,
e. g., for cutting opera-
tions using the cutting
guide with dust extrac-
tion protection guard
24
or for left-handed persons.
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. Touching or breathing-in the dusts can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dusts, such as oak or beech dust, are considered
as carcinogenic, especially in connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
Prevent dust accumulation at the workplace.
Dusts can
easily ignite.
Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er 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 genera-
tors that do not have sufficient reserve capacity or are not
equipped with suitable voltage control with starting current
amplification, loss of performance or untypical behavior can
occur upon switching on.
Please observe the suitability of the power generator being used,
particularly with regard to the mains voltage and frequency.
