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 grind-
ing tools can burst and cause injuries.
Kickback stop
(EWS 125-S/EWS 125-ES/
EWS 14-125 S/EWS 14-150 S)
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 interrupted.
To restart the operation, switch the On/Off
switch 4 to the Off position and start the machine
again.
Speed preselection (EWS 125-ES)
The required speed can be preselected with the thumbwheel 3 (also while running).
The data in the following table are recommended values.

Working Advice
❏ Exercise caution when cutting slots in
structural walls; see Section "Information
on Structures ".
❏ 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.

Restarting Protection
(EWS 125-S/EWS 125-ES/
EWS 14-125 S/EWS 14-150 S)
The restarting protection feature prevents uncon-
trolled restarting of the machine after an interruption
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
(EWS 125-S/EWS 125-ES/
EWS 14-125 S/EWS 14-150 S)
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
(EWS 125-S/EWS 125-ES/
EWS 14-125 S/EWS 14-150 S)
Constant electronic control holds the speed constant
at no-load and under load, and ensures uniform
working performance.

Rough Grinding
❏ Never use a cutting disc for roughing.
The best roughing results are achieved when setting
the machine at an angle of 30° to 40°. Move the
machine back and forth with moderate pressure. In
this manner, the workpiece will not become too hot,
does not discolour and no grooves are formed.
Flap Disc
With the flap disc (accessory), curved surfaces and
profiles can be worked.
Flap discs have a considerably higher service life,
lower noise levels and lower sanding temperatures
than conventional sanding sheets.
