3 Operating
EN Wall and ceiling grinding machine WDS 530 C
24
When the lever is set at the position for "Ceiling"
[Fig. X], the pressure cylinder is operated at in­
creased pressure to compensate the weight of
the grinding machine head [16, Fig. B].
2. 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!
3. Switch on the tool rotation and the contact pres­
sure using the remote control of the guiding ma­
chine
(
!
operating manual of the guiding machine,
chapter
Operation of double-acting hydraulic
tools ).
4. Measure the speed of the gear disc [43, Fig. Y]
on the lid [44, Fig. R] using a suitable measuring
instrument.
The maximum speed of the gear disc was set to
maximum 120 rpm when the guiding machine
was adapted to the grinding machine. This pre­
set hydraulic volume flow of the guiding machine
may not be changed!
The controller [5, Fig. Y] can be used to reduce
the gear disc speed.
5. Use the controller [5, Fig. Y] to set the desired
gear disc speed if necessary.The manufacturer
of the grinding machine can gladly provide
corresponding recommendations.
The contact pressure [50, Fig. AB] is created in
the grinding machine from the supply pressure
and in its delivery condition is approx. 1000 N
(wall) and approx. 800 N (ceiling). The contact
pressure is consistent in the range between the
minimum gap [26, Fig. G] and maximum gap
[24, Fig. G].
The contact pressure may only be changed us­
ing the controller [48/49, Fig. AA]!
6. Set the contact pressure if necessary:
a.
Remove the cover [47, Fig. Z].
b. Use the controller [48/49, Fig. AA] to set
the required contact pressure.The manu­
facturer of the grinding machine can gladly
provide corresponding recommendations.
c. Mount the cover.
7. Switch off the tool rotation and the contact pres­
sure using the remote control of the guiding ma­
chine.
8. Move the grinding machine head with the grind­
ing tools into work position (
!
Fig. AC).
During the grinding process, the depth display
[22, Fig. G] should always be between the maxi­
mum value [24, Fig. G] and minimum value
[26, Fig. G].
The grinding machine head is moved by the
guide arm [18, Fig. B] and the travel motion of
the guiding machine.
The grinding machine head adjusts itself to the
angle of the surface vertically and horizontally
by ±6° (
!
Fig. V).
This tilt angle should not be exceeded, because
otherwise the grinding tool does not contact the
wall or ceiling and causes imperfections.
9. Switch on the tool rotation and the contact pres­
sure using the remote control of the guiding ma­
chine.
The surface to be ground can now be machined.
3.3 Ending the operation
Observe the safety instructions in Chapter 2!
The drive and the position of the grinding machine
head is controlled by the operating elements of the
guiding machine.
Risk of injury from grinding tools still rotating
after the grinding machine is switched off!
The tool holder disc can continue to turn in idle
(run‐on) for several seconds after switch off!
1. Switching off the grinding machine head
(

operating manual of the guiding machine) .
The
contact pressure is relieved.
The
grinding machine head
is moved to starting
position
[25, Fig. G]
.
2. Place the grinding machine with the supporting
feet [11, Fig. B] on a level, horizontal floor with
adequate load capacity (e.g. pallet or floor).
3. Either
If the grinding machine is not to be used further:
