Installation and operation
– Screw the cutting shaft nut (left-handed thread)
tightly on the cutting shaft (fig. 4.9).

– Close the blade guard (fig. 2.1, 4.3 and 4.7).
NOTE
Make sure that the wire for opening the blade
guard does not get clamped!
WARNING!
Danger! It is not permitted to operate the
joint cutter without blade guard.
– Check the running smoothness and the blade fixing
by a short run of the freely rotating saw blade (refer
to section 4.6).
WARNING!
Danger due to insufficient blade fixing and
wobbling diamond saw blade!
A saw blade with insufficient core tension is noticeable
by untrue and wobbling running.
ATTENTION!
To avoid damages to the saw blade it has
to be dismounted when transporting the
machine.
4.3 Activating and adjusting
the fixing brake
The joint cutter CF-12.4 E-TR is automatically slowed
down (fixed against autonomous displacement) as
soon as the cutting shaft has been raised to its highest
position.
– Turn the cutting shaft by means of the hand crank in
the highest position (refer to section 4.2.2)

.
In this position the joint cutter’s left rear left wheel will
be blocked by the combined fixing device and cutting
depth indicator (fig. 4.10).

The braking force is adjusted as follows:
– Loosen the counter nut and turn the stopper screw
out of the lever to increase the braking effect or turn it
into the lever to reduce the braking effect (fig. 4.10).
NOTE
To increase the breaking effect (to obtain a higher
pressure of the stopper screw) lower the cutting
shaft by 2 revolutions of the hand crank (fig. 4.4). Turn
the stopper screw against the wheel and secure it.
ATTENTION!
Additional means must be used to pre-
vent the joint cutter from rolling or slip-
ping away where the ground slopes severely.
