Approved Grinding Tools
All grinding tools mentioned in these operating
instructions can be used.
The permissible speed [rpm] or the circumferential
speed [m/s] of the grinding tools used must at least
match the values given in the table.
Therefore, observe the permissible rotational/cir-
cumferential speed on the label of the grinding tool.

Operation

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
When operating the machine with power from mobile
generators that do not have sufficient reserve capacity
or are not equipped with suitable voltage control with
starting current amplification, loss of performance or
[m/s]
untypical behavior can occur upon switching on.
Please observe the suitability of the power generator
being used.

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 grinding tools can
burst and cause injuries.
with
Reduced starting current (GWS 1400)
the
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 (GWS 1400)
Constant electronic control holds the speed constant
at no-load and under load, and ensures uniform work-
ing performance.
Operating Instructions
guard
Exercise caution when cutting slots in struc-
tural walls; see Section "
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.
