– Make sure that the cutting shaft (thread) and es-
pecially the blade flanges are clean. If necessary,
remove any dirt with a lint-free cloth.
– Check the diamond saw blade and mount it on the
blade mounting flange of the cutting shaft.
WARNING!
Danger! Check the rotational sense of the
diamond saw blade, its true running and
any damages.
Any damages/missing diamond segments or untrue
running exclude the use of the saw blade!
The rotational sense of the cutting shaft has to
comply with the saw blade’s cutting direction.
The rotational sense of the cutting shaft is marked by
an arrow on the blade guard (fig. 4.7).

There is an arrow on the diamond saw blade that
indicates the cutting direction (fig. 4.9). If this arrow is
not visible the cutting direction of the saw blade can be
determined as follows: During cutting, a “tail” is formed
behind the diamond; thus the diamond is always in front
of the “tail” in relation to the rotational sense (fig. 4.8).

Diamond saw blades are designed to be self-
sharpening in operation. However, they can be-
come blunt through frequent cutting in heavy steel
armouring or in hard material which is only slightly
abrasive. Blades can be resharpened by cutting in an
abrasive material such as lime sandstone or asphalt.
– Set the diamond saw blade on the blade mounting
flange of the cutting shaft.
– Set the blade receiving flange with its ring-shaped
surface and the clamping ring (chamfer outside) on
the cutting shaft (fig. 4.5, 4.6 and 4.9),
NOTE
Make sure that the drive pin projects into the blade
receiving flange.
