replaced. Repairs are not permitted.
TC circular saw blades with saw-tooth dimen
sions below 1mm may no longer be used (Figure A).
Steel circular saw blades: Circular saw blades
with visible cracks may not be used.
Circular saw blades must be inserted into handheld circular saws only when the saw is equipped

Fastening Circular Saw Blades and
Machine Components
When replacing a saw blade, rule out accidental
starting of the power tool/woodworking ma
chine.
Mount and secure the circular saw blade in ac
cordance with the regulations of the machine
manufacturer. Observe the regulations specified
by the machine manufacturer.
Circular saw blades and machine components
must be clamped in such a manner that they can
not become loose during operation. Observe the
information supplied by the manufacturer.
When mounting the circular saw blade, make
sure that the hub of the tool is properly clamped
and that the saw blade teeth are not in contact
with any part of the machine (no grazing).
Extending spanners or using hammers or similar
for tightening purposes is not permitted.
The clamping surfaces must be free of grease, oil
and water.
The use of loose-fitting reduction rings or bush
ings is not permitted.
The use of secure-fitting Bosch rings, e. g.
pressed in or held by means of adhesion, is per
mitted if they are correctly mounted in accordance with figure B (see cover pages).
The ring thickness must always be smaller than
the thickness of the base blade body.
