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 diamond segments and
the quality of the concrete.
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
reinforcement completely
– If the reinforcement is not cut through
completely 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.
1) Withdraw the blade carrying out swi-
velling or feed motions carefully.
2) 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
rotating
– Move the swivel arm to the uppermost
position
– Switch off blade drive
