CAUTION
Cutting discs which are damaged or out of round
(causing vibration) must not be used.
CAUTION
Do not use synthetic resin-bonded fiber-reinforced
en
cutting discs that have exceeded their use-by date.
NOTE
Diamond cutting discs in compliance with the require-
ments of ANSI B7.1 are to be used with the power tool.
Synthetic resin-bonded fiber-reinforced cutting discs in
compliance with ANSI B7.1 (cutting-off wheels of the
straight, not offset type) may also be used with this
power tool for working on metals. In this case, the appro-
priate DCH 300 ABR disc mount (see accessories) must
be used with the power tool. The mounting instructions
issued by the disc manufacturer must also be observed.
6.3.1 Fitting diamond cutting discs
G
The width of the slot G between the segments must not
exceed 10 mm (³⁄₈"). The thickness of the disc must not
exceed 3.5 mm (¹⁄₈").
The 60 mm dia. interchangeable flange can be used
on one side for cutting discs with an inner diameter of
22.2 mm (⁷⁄₈") or, on the other side, with cutting discs
with an inner diameter of 25.4 mm (1"). Check which side
of the flange fits the arbor hole in the cutting disc. The
flange must center the disc.
1. Disconnect the supply cord plug from the power
outlet.
2. Clean the clamping flange and the clamping nut.
3. Fit the 60 mm diameter reversible flange onto the
spindle the right way round, so that it is no longer
free to rotate.
4. Place the diamond cutting disc on the reversible
flange.
5. Fit the 60 mm diameter clamping flange and the
clamping nut.

CAUTION
Never use flanges with a diameter of less than 80 mm
with synthetic resin-bonded fiber-reinforced cutting
discs.
The 80 mm dia. interchangeable flange can be used
on one side for cutting discs with an inner diameter of
22.2 mm (⁷⁄₈") or, on the other side, with cutting discs
with an inner diameter of 25.4 mm (1"). Check which side
of the flange fits the arbor hole in the cutting disc. The
flange must center the disc.

Store the cutting disc in accordance with the manu-
facturer's recommendations. Incorrect or careless stor-
age may damage the cutting disc.

position.
Use the wrench to tighten the clamping nut securely
and then release the spindle lockbutton.
Check to ensure that the spindle lockbutton has
disengaged.
6.3.2 Fitting synthetic resin-bonded fiber-reinforced
abrasive cutting discs (optional)
Disconnect the supply cord plug from the power
outlet.
Clean the clamping flange and the clamping nut.
Fit the 80 mm diameter reversible flange onto the
spindle the right way round, so that it is no longer
free to rotate.
Place the diamond cutting disc on the reversible
flange.
Fit the 80 mm diameter clamping flange and the
clamping nut.
CAUTION Do not press the spindle lockbutton
