Chapter 3.1, Page 7).
Risk of injury from inadvertent starting and movement of
the grinding machine or guiding machine!
Risk of injury from loose parts!
During operation, loose parts (stones / removed material /
broken components / tools etc.) can be flung out!
Keep at least 5 m safety distance from the grinding ma
chine and from the guiding machine!
The operating and maintenance personnel responsible for
the grinding machine must ensure that no one can enter
the grinding machine’s danger zone during operation or
maintenance work!
Risk of injury and fire hazard from hot surfaces on the ma
chine housing, tool mounts and grinding tools!
Wear protective gloves!
Have suitable fire extinguishers on hand!
Work with the greatest care and caution!
The dust cover ring must always contact the surface being
machined during operation (

The manufacturer of the grinding machine urgently recom
mends practising the grinding of walls, ceilings and floors
sufficiently.
1.
Switch the guiding machine on.
When the grinding machine is switched on at the controller of
the guiding machine, the contact pressure of the grinding
machine head is applied by the hydraulic control system and
is not operated via operating elements of the guiding
machine.
Risk of injury from rotating machine parts!
Work with care!
2.
Switch on the tool rotation and the contact pressure using
the remote control of the guiding machine
(

operating manual of the guiding machine,
chapter
Operation of double‐acting hydraulic tools
).
3.
Measure the speed of the gear disc [42] with a suitable mea
suring instrument.
GG"
The maximum speed of the gear disc was set to maximum
2000 rpm when the guiding machine was adapted to the
grinding machine. This preset hydraulic volume flow of the
guiding machine may not be changed!
When the guiding machine is changed, the maximum speed
must be reset to 1800 rpm .... 2000 rpm.
4.
Use the controller [5] to set the desired gear disc speed if
necessary.The manufacturer of the grinding machine can
gladly provide corresponding recommendations.
