6.3 After the first cut
Further infeed
After the first cut further infeed can be more
than 5-10 cm. The depth of cut depends on
the power of the connected power unit, the
size of the saw blade the quality of the dia-
mond segments and the quality of the concre-
te.
Optimum depth of cut can vary between
5 and 15 cm.
Sawing reinforcements
When sawing in longitudinal direction of the
reinforcements:
•
Cut deep enough to saw through the rein-
forcement completely
•
If the reinforcement is not cut through com-
pletely the wall saw will deviate
Do not saw with the highest admissible
pressure of the power unit in sections
where only concrete is sawed. Stay
about 40 bar below. If the blade encoun-
ters reinforcement the pressure will then
not exceed the admissible maximum.
Always withdraw the saw blade while it
is still rotating.
If the saw blade is blocked
Never attempt to free the saw blade by
strong feed force.
•
Withdraw the blade carrying out swivelling
or feed motions carefully.
•
If you do not succeed, disconnect the saw
blade from the wall saw head and remove
the saw blade from the incision.
End of cut
•
Withdraw the saw blade while it is still rota-
ting
•
Move the swivel arm to the uppermost posi-
tion
•
Switch off blade drive
