Initial Operation
Observe correct mains voltage: The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.
Switching On and Off
To start the machine, press the On/Off switch 3
forward and then down.
To lock-on, push the pressed On/Off switch 3
further forwards.
To switch off the machine, release the On/Off
switch 3 or push and release it then.
Switch version without lock
(country-specific):
To start the machine, press the On/Off switch 3
forward and then down.
To switch off the machine, release the On/Off
switch 3.
Test run!
Check the grinding tool before use. The grind-
ing tool must be properly mounted and rotate
freely. Perform a test run of at least
30 seconds without load. Do not use dam-
aged, out-of-round or vibrating grinding tools.
Run-on Brake (BTI-WKS 230 SE)
This machine is equipped with the
BTI Brake System.
When switching off or in case of a power supply
interruption, the grinding tool is stopped within a
few seconds. This means the run-on time is re-
duced by approx. 70 % in comparison to angle
grinders without run-on brake, and that the ma-
chine can be placed down in shorter time.
Should the braking effect of the run-on brake no-
ticeably diminish, have the machine checked by
an after-sales service centre for BTI power tools.
Reduced Starting Current
As a result of soft starting, a 13 A fuse is ade-
quate.

Rough Grinding
Flap Disc
With the flap disc (accessory), curved surfaces
and profiles (contour sanding) can be worked.
Flap discs have a considerably higher service life
than sanding sheets, lower noise level and lower
sanding temperatures.
Cutting
Do not reduce the speed of running down cutting
discs by applying sideward pressure.

Operating Instructions
Clamp the workpiece if it does not remain
stationary due to its own weight.
Do not strain the machine so heavily that it
comes to a standstill.
Grinding and cutting discs become very
hot while working; do not touch until they
have cooled.
The best roughing results are
achieved when setting the machine
at an angle of 30° to 40°. Move the
machine back and forth with mod-
erate pressure. In this manner, the
workpiece will not become too hot,
does not discolour and no grooves
are formed.
Never use a cutting disc for roughing.
When cutting, do not press, jam or
oscillate the machine. Work with
moderate feed, adapted to the ma-
terial being machined.
The direction in which
the cutting is per-
formed is important.
The machine must
always work in an
up-grinding
motion.
Therefore,
never
move the machine in
the other direction!
Otherwise, the dan-
ger exists of it being
pushed
uncon-
trolled out of the cut.
