All grinding tools mentioned in this operating
manual instruction can be used.
The permissible speed [rpm] or the circumferen-
tial speed [m/s] of the grinding tools used must at
least match the values given in the table.
Therefore, always observe the permissible
rotational/circumferential speed on the label
of the grinding tool.
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 1
forward.
To lock-on, press the On/Off switch 1 down at
the front until it engages.
To switch off the machine, release the On /Off
switch 1 or press the rear tip of it down.
☞
Test run!
Check the grinding tool before use. The
grinding tool must be properly mounted
and rotate freely. Perform a test run of at
least 30 seconds without load. Do not use
damaged, out-of-round or vibrating grind-
ing tools.
Constant Electronic Control
(PWS 8-125 CE/PWS 850 CE/
PWS 9-125 CE)
Constant electronic control holds the speed con-
stant at no-load and under load, and ensures uni-
form working performance.
Overload Protection (PWS 8-125 CE/
PWS 850 CE/PWS 9-125 CE)
When overloaded, the motor comes to a stop.
Relieve the load on the machine immediately and
allow to cool for approx. 30 seconds at the high-
est no-load speed.
Preselect the required speed using the thumb
wheel 2 according to the table following the sec-
tion “Product Specification” (reference values).
■
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.
Rough Grinding
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.
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.
