7 Operation

WARNING
Wear personal protective equipment. Exposure to
noise can cause hearing loss.
WARNING
Test new cutting or grinding discs by allowing them
to run at maximum speed in a protected area for at
least 30 seconds.
WARNING
Slits cut in loadbearing walls of buildings or other struc-
tures may influence the statics of the structure, especially
when steel reinforcing bars or load-bearing components
are cut through. Consult the structural engineer, ar-

Lock nut.
NOTE
The arrow on the upper surface of the nut must be within
the index marks. If the arrow is not within the index marks
when the nut is tightened it will be impossible to release
the nut by hand. In this case, use the pin wrench to
