Operation
Starting Operation
The voltage and frequency of the power
source must correspond with the data on
the type plate of the power tool.
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.
If the machine should unexpectedly stop
operating even though the On/Off switch 1
is in the "On" position, set the On/Off
switch to "Off". This will prevent uncon-
trolled restarting of the machine. Before re-
starting the machine, check the power sup-
ply (see "Connection to the Power Supply",
page 49).
Always connect the power tool to the fre-
quency converter first, before connecting
the frequency converter to the mains sup-
ply.
Switching the Frequency Converter On/Off
The frequency converter must be put into oper-
ation first before actuating the power tool.
For this, observe the operating instructions of
the frequency converter.

Working Advice
Disconnect the power supply before mak-
ing any adjustments, changing accessories,
or placing the machine aside. This safety
measure prevents accidental starting of the
power tool.
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.
After heavily straining the power tool, con-
tinue to run it at no-load for several minutes
to cool down the cutting/grinding tool.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
Sanding with the 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 tem-
peratures than conventional sanding sheets.
