Installation and operation
4.8
Cutting operation
ATTENTION!
As a basic principle the joint cutter is to
be brought directly to the place of opera-
tion before the engine (and saw blade) is started.
Transport and displacing beyond the working area
are forbidden with freely running saw blade.
Observe the preceding chapters and section, par-
ticularly the safety and warning instructions
!
Ear protectors must be worn!
ATTENTION!
According to the respective operating
conditions, wearing of further personal
protection equipment might be necessary!
ATTENTION!
During cutting operation a safe distance
(approx. 10 m) for third persons must be
kept.
The operator’s working position is behind the joint
cutter (push handle).
If the safe distance cannot be kept constructionally,
the direct range of danger is to be closed off or to be
provided with danger signs.
Pay attention to objects and building parts to be pro-
tected (remove or cover them). Pay attention as well to
the whereabout, the discharge (collection) of the cool-
ing and rinsing water, of the slurry and of the materials
to be cut.
– Align the joint cutter to the cutting line.
– Lift the diamond saw blade out of the material to be
cut.
– Connect the vacuum cleaner at the saw blade guard!
– Switch on the vacuum cleaner!
– Start the engine.
– Bring the engine/the saw blade on full number of
revolutions.
– Start up the suction (vacuum cleaner)!
– Lower the saw blade slowly to the cutting depth
desired (see cutting depth indicator). Hold the joint
cutter tightly!
NOTE
Do not lower the saw blade too fast to prevent
damages to the saw blade and the joint cutter.
NOTE
A precise pre-cut at a moderate depth will make
all following cuts easier and will lead to an exact
cutting course!
– After having lowered the saw blade to the desired
cutting depth, lock the cutting depth adjustment.
– The feed is generated by pushing the joint cutter
forward. Push the joint cutter slowly and maintain a
steady speed.
NOTE
Choose the feed rate in such a way that the
engine’s number of revolutions is slightly slowed.
– Follow the cutting line (pointer) and constantly
observe the cutting area (particularly the dust
removal) in order to be able to intervene and to stop
the cutting process at any time should this become
necessary.

Finishing the cutting operation
– Move the joint cutter a little backwards in order to al-
low the diamond saw blade to turn freely in the cut.
– Release the hand crank and raise the diamond saw
blade out of the cut. Keep the machine in its position.
Now secure the hand crank against unintentional
displacement.
– Activate the fixing brake as described in section 4.3.
– Shut the engine off.
– Switch off the vacuum cleaner!
– Remove the diamond saw blade.
– Carry out maintenance and care work according to
chapter 5
.
4.10 Replacing the diamond saw blade
The diamond saw blade is replaced:
– after complete wear of the diamond segments
– if you want to cut a different kind of material.
Replacing the diamond saw blade is absolutely neces-
sary:
– if it is worn unevenly
– if the diamond segments are damaged or broken off.
For mounting a new diamond saw blade please pro-
ceed as described in section 4.2.
