6.2 Fitting and changing the cutting disc 3
CAUTION
Cutting discs which are damaged or out of round
(causing vibration) must not be used.
CAUTION
The maximum permissible speed of the disc or blade
must be at least as high as the maximum speed
printed on the machine.Accessories driven at a speed
above their maximum permissible speed may break and
fly apart.
CAUTION
Use only cutting discs with a 20 mm or 25.4 mm (1")
arbor hole.
CAUTION
The cutting discs, flanges or other accessories must
properly match the arbor size of the machine. Cut-
30
ting discs or accessories with arbor holes that do not
match the mounting hardware of the machine will run out
of balance, vibrate excessively and may cause loss of
control.
CAUTION
Don't use synthetic resin-bonded fiber-reinforced
cutting discs that have exceeded their use-by date.
CAUTION
Don't use damaged diamond cutting discs (cracks in
the steel disc, broken or polished segments, damaged
arbor hole, bent or distorted steel disc, heavy discol-
oration due to overheating, steel disc worn away
beneath the segments, diamond segments with no
lateral overhang, etc.)
1. Insert the locking pin in the hole in the drive belt
cover and turn the cutting disc until the locking pin
engages.

is provided with a 20 mm diameter centering collar
on one side and a 25.4 mm (1") diameter centering
collar on the opposite side.
5. Clean the clamping and centering surfaces on the
machine and on the cutting disc.
CAUTION Take care to ensure that the direction
6.
of rotation of the cutting disc (indicated by an ar-
row) matches the direction of rotation shown on the
machine.
Place the cutting disc on the centering collar of the
clamping flange.
7. Place the clamping flange on the drive arbor and
tighten the cutting disc clamping screw by turning it
clockwise.
8. Insert the locking pin in the hole in the drive belt
cover and turn the cutting disc until the locking pin
engages.
9. Tighten the cutting disc clamping screw to a torque
of 25 Nm.
