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.

Operating Instructions
❏ 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.
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.
Cutting Metal
❏ For cutting metal, always work with the
protection guard for cutting 8.
When cutting, work with moderate feed, adapted to
the material being cut. Do not exert pressure onto
the cutting disc, tilt or oscillate the machine.
Do not reduce the speed of running down cutting
discs by applying sideward pressure.

Information on Structures
Slots in structural walls are subject to the Standard
DIN 1053 Part 1, or country-specific regulations.
These regulations are to be observed under all cir-
cumstances. Before beginning work, consult the
responsible structural engineer, architect or the con-
struction supervisor.
❏ Before any work on the machine itself,
pull the mains plug.
❏ For safe and proper working, always keep
the machine and ventilation slots clean.
❏ In extreme working conditions, conductive
dust can accumulate in the interior of the
machine when working with metal. The
protective insulation of the machine can
be degraded. The use of a stationary
extraction system is recommended in such
cases as well as frequently blowing out the
ventilation slots and installing a residual
current device (RCD).
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair
should be carried out by a Würth master-Service.
