Guide cut Guide cuts are used to guide the blade so that it does not drift and
should always be performed for safety reasons. Guide cuts should only
be performed with blades with a maximum blade diameter of 400mm.
It is important that this guide cut is very straight!
Pre-cut Large depths cannot be cut in a single pass. Therefore, for blade
diameters of 534mm, pre-cuts must be made. The pre-cuts must be
performed with a blade of small diameter and with wide segments.
4.3.2.7 Sawing
If the cutouts are performed with overcuts, please note: the length of the overcut is
directly related to the cutting tool diameter selected, the plunging depth of the cutting tool
and the thickness of the concrete. If the cutouts are performed without overcut, the tool is
used to cut as far as the corners and then the remaining cut is performed with the
diamond bar saw (ICS). Sawing can now commence.
Feed after the pre-cut or guide cut
Following the pre-cut or guide cut more than 50-80 mm can be fed. The possible cutting
depth depends on the level of reinforcement, the aggregates in the concrete, the size of
the cutting tool, the blade specification and the drive assembly power.
Reinforcements in the longitudinal direction
When cutting it must be ensured that when plunged the tool is not in contact with any
reinforcement that runs alongside the cut. Ensure the operator cuts through the steel
completely and also has contact with concrete for sharpening effect.

Information
The depth of the precut must be selected to guarantee that any reinforcements running
alongside the cut are completely cut through. If the cutting tool runs along in the
reinforcement, there is a danger of the cut drifting with heavy wear of the tool rendering it
defective.
If the saw blade jams
•
Carefully withdraw from the cut with travelling or swivelling motions.
•
If this is not possible: Disassemble cutting tool from saw head and remove cutting
tool alone from the cut.
