To
switch off
the power tool, slide the on/off
switch
(1)
backwards so that
"0"
appears on the
switch.
BOT STARLOCK PLUS: The worklight improves
visibility in the immediate working area. It is auto-
matically switched on and off with the power tool.
u
Do not look directly into the worklight; it can
blind you.
Preselecting the orbital stroke rate
English
You can even preselect the required orbital stroke
rate during operation using the orbital stroke rate
preselection thumbwheel
(2)
.
The required orbital stroke rate is dependent on
the material and the work conditions and can be
determined using practical tests.
Orbital stroke rate level “6” is recommended for
sawing, cutting and sanding harder materials,
such as wood or metal; orbital stroke rate level
“4” is recommended for softer materials, such as
plastic.
Practical Advice
English
u
Pull the plug out of the socket before carry-
ing out any work on the power tool.
u
Always wait until the power tool has come to
a complete stop before placing it down.
Note:
Do not keep the ventilation slots
(3)
on the
power tool closed when working as this will re-
duce the service life of the power tool.
Operating principle
English
The oscillating drive causes the application tool to
oscillate back and forth up to 20000 times per
minute. This enables precise work in the tightest
of spaces.
Use a consistent, low contact
pressure when performing work;
otherwise, the performance will
be impaired and the application
tool may jam.
While working, move the power
tool back and forth to prevent the
application tool overheating and
jamming.
Sawing
English
u
Use only undamaged saw blades that are in
perfect condition.
Bent or dull saw blades can
break, negatively influence the cut, or lead to
kickback.
u
When sawing lightweight materials, take into
account the statutory provisions and recom-
mendations of the material manufacturers.
u
Plunge cuts may only be applied to soft ma-
terials, such as wood, gypsum board, etc.
Before using HCS saw blades to saw into wood,
chipboard, building materials, etc., check these
saw blades for foreign objects, such as nails,
screws, etc. Remove the foreign objects as re-
quired or use bi-metal saw blades.
Cutting
English
Note:
When cutting wall tiles, please bear in mind
that the application tools are subject to high wear
if used for extended periods.
Sanding
English
The material removal rate and sanding result are
primarily determined by the choice of sanding
sheet, the preselected orbital stroke rate level and
the contact pressure.
Only immaculate sanding sheets achieve good
sanding performance and make the power tool
last longer.
Be sure to apply consistent contact pressure in
order to increase the lifetime of the sanding
sheets.
Excessively increasing the contact pressure will
not lead to increased sanding performance, rather
it will cause more severe wear of the power tool
and of the sanding sheet.
To sand corners, edges and hard-to-reach areas
accurately, you can also work with the tips alone
or with an edge of the sanding plate.
The sanding sheet may heat up significantly when
used to sand specific points rather than entire sur-
faces. Reduce the orbital stroke rate and contact
pressure and allow the sanding sheet to cool
down at regular intervals.
Do not use a sanding sheet for other materials
after it has been used to work on metal.
Use only original
Berner
-sanding accessories.
Always connect a dust extraction system for sand-
ing.
Sanding application table
English
The information about the grit of the sanding
sheet and the orbital stroke rate level in the fol-
lowing table are recommended values.
The best method for determining the best com-
bination while sanding or polishing is practical ex-
perimentation.
