After the first cut more than 5-10 cm can be
fed. The possible cutting depth is dependent
upon the mount of reinforcement and the
aggregates in the concrete and the size and
specification of the blade.
The optimum cutting depth can be between
7 and 12 cm.

For cuts following the length of the
reinforcement:
z Prepare the cut so that the reinforcement is
completely cut through.
z Do not plan the cut along the reinforcement.
The cut would otherwise drift.

In sections where there are no reinforcing
rods do not use high power cutting, but
reduce this by about 40 bars.
If the blade touches any reinforcing rods,
the pressure will not then increase above
the maximum permitted level.
Always withdraw from a cut with the saw
blade running.
