Installation and operation
4.4
Adjusting and using the
front pointer
The front pointer for following the cutting line is loosely
fixed at the joint cutter’s frame. It enables the operator
to cut precisely on a marked line (fig. 2.1). If the pointer
has been bent during transport, it can be aligned as
follows:
WARNING!
Danger of injury! Shut the motor off.
Disconnect the joint cutter from the mains
supply by unplugging the power plug. Secure the
joint cutter against unintentional starting or rolling
away.
– Mount the diamond saw blade and leave the blade
guard open.
– Stretch out a cord or place an alignment bar parallel
to the diamond saw blade and align the pointer
accordingly (fig. 4.11).
– Close the blade guard.

Dry cutting
WARNING!
Only carry out dry cutting operation with
sufficient protection against dust (per-
sonal protection devices, dust suction, ….)!
According to the Accident Prevention & Insurance As-
sociation’s regulations the forming of fine dusts which
are hazardous to health must be prevented as far as
possible.
ATTENTION!
Cutting tools (diamond saw blades) that
are designed for wet cutting only, may
never be operated without water in a dry cutting
process. This heavily reduces the tool’s life time
and loss of segments will inevitably occur.
Make sure that always sufficient dust is removed
from the tool (diamond saw blade)!
In case of formation of dust the suction capacity must
be increased! This will cool down the saw blade (dia-
mond segments) and clear the cut (joint).
ATTENTION!
Only use suction devices (professional-
type vacuum cleaners) in dry cutting
which are designed for this kind of dust and quan-
tity to prevent blockage of the suction system.
Observe the essential connecting specifications, see
chapter 1!
ATTENTION!
Pass the suction hose to the blade guard
in such a way that any damage caused by
the saw blade or tripping over is excluded.
WARNING!
It is prohibited to convert this machine to
do wet cutting and to operate the
CF-12.4 E-TR with a water tank mounted above the
electric motor!
The electric motor’s grade of insulation does not allow
a water tank to be mounted abover the motor.
The machine frame of the CF-12.4 series of joint cut-
ters serves as well for mounting a gasoline or diesel
motor (CF-12.4 B and CF-12.4 D). Alternatively to the
pressu-rized water supply the joint cutters with combus-
tion motors can be equipped with a water tank (above
the motor) (refer to the corresponding operating man-
ual). The mounting devices for the water tank console
are not required for the CF-12.4 E-TR (fig. 4.12). The
efforts to remove the console would be too high and
furthermore they provide additional ballast for the joint
cutter’s running smoothness.
