Mounting to a Working Surface (see figure A)
– Fasten the power tool with suitable screw fasteners to the
working surface. The mounting holes 11 serve for this pur-
pose.
Flexible Mounting (not recommended!)
In the exceptional case that it should not be possible to firmly
bench-mount the power tool, you can provisionally place the
legs of base plate 13 on a suitable surface (e. g. a workbench,
level floor, etc.) without bolting the machine down.
Changing the Tool (see figures B1–B2)
 Actuate the spindle lock 5 only when the tool spindle
22 is stopped. Otherwise, the machine can become dam-
aged.
 Do not touch the cutting disc after working before it
has cooled. The cutting disc becomes very hot while work-
ing.
Use only cutting discs that correspond to the characteristic
data given in these operating instructions and are checked ac-
cording to EN 12413 and marked appropriately.
Use any intermediate layers provided with the cutting disc.
