Description of the joint cutter CF-22 E.800
The electrically driven CF-22 E.800 is suitable as a joint cutter for wet cutting with diamond saw blades in places where, due
to exhaust and/or noise protection regulations, machines with combustion engines may not be used (e.g. closed rooms).
Despite its compact design, the CF-22 E.800 achieves a cutting depth of 320mm, thus enabling even more demanding
cutting operations.
The 3 transport-friendly assemblies enable fast transport, e.g. in a hatchback car, and allow the CF-22 E.800 to be
assembled directly at locations that are dicult to access. The assemblies can be put together and taken apart in a few
simple steps, without requiring additional tools.
2.0 Description of the joint cutter CF-22 E.800
The arrangement of all components of the CF-22 E.800
joint cutter with the resulting weight distribution provides
sucient contact pressure on the diamond saw blade
while at the same time being easy to handle during
transportation and set-up.
The modular design facilitates cleaning, maintenance and,
if necessary, repair.

Description of the joint cutter CF-22 E.800
The cutting shaft, and with it the saw blade, is driven by an
electric motor via V-belts.
The blade can be mounted on the right or left side.
Theblade guard can be repositioned for this purpose.
Feed is achieved by pushing the adjustable push handle.
The saw blade is lowered and raised by means of a lockable
hand crank and a trapezoidal threaded spindle.
The cutting depth can be progressively adjusted up to
320mm.
The cutting shaft is mounted in two self-aligning pedestal
bearings. The precision-engineered shaft has a 25.4mm
diameter blade mounting ange.
The front pointer is mounted on the joint cutter frame.
Itenables the user to cut accurately along a line.
The diamond saw blade is supplied with pressurized water
via the Geka coupling and an adjustable shut-o valve.
The drive unit and cutting shaft's speed have been
designed to provide the best possible conditions for
cutting with CEDIMA® diamond saw blades.
For cutting, we recommend CEDIMA® diamond saw blades
which ensure protection of the joint cutter due to their
ease of cutting and their smooth movement.

4.3 Mounting the diamond saw blade
4.3.1 General information
The drive unit and cutting shaft's speed have been
designed to provide the best possible conditions for
cutting with CEDIMA® diamond saw blades.
Select the saw blade type according to the material to be
cut.
Observe the diameter of the saw blade receptacle and the
blade shaft!
Please refer to chapter “Technical specications and
accessories” for details.
The maximum permissible saw blade diameter is 800mm!
Ask CEDIMA® about the correct saw blade type and the
reducer ring.
CEDIMA® will refuse any warranty in case of improper use
of the saw blades!
Complaints about delivered CEDIMA® saw blades can only
be accepted if there is a remaining diamond segments'
height of 20%!
4.3.2 Lifting the cutting shaft
DANGER!
Make sure that the joint cutter can not be
started unintentionally by isolating the motor
from the power supply!
The diamond saw blade can be lowered and lifted using
acrank handle with threaded spindle.

4.3.3 Mounting the saw blade
1. Loosen the clamping screw on the blade guard, then lilft
and remove it.
Figure 4.5
Direction of rotation arrow on blade guard
2. Loosen and remove the cutting shaft nut using the double
open-ended wrench supplied as an accessory.
Cutting shaft nut
Figure 4.6
3. Remove the air lter cover.
4. Make sure that the cutting shaft and the blade anges are
clean. If necessary, remove any dirt with a lint-free cloth!
DANGER!
Before mounting, check the true running
accuracy of the diamond saw blade and make
sure it is not damaged!
The diamond should not be used in case of damaged or missing
diamond segments or if it runs out of true!
The direction of rotation of the cutting shaft must match the
direction of rotation of the saw blade!
The sense of rotation of the cutting shaft is marked by an
arrow on the blade guard (Fig.4.7).
Imprinted on the saw blade is an arrow for the cutting
direction. If this arrow is not visible, the cutting direction of
the saw blade can be determined as follows: During cutting,
a“tail” is formed behind the diamond; therefore, the diamond
is always in front of the “tail” (direction of rotation).
Diamond saw blade mounted in the correct direction of rotation Fig. 4.7
5. Mount the diamond saw blade and the clamping ange
onto the cutting shaft and tighten the cutting shaft nut
securely.
Make sure that the drive pin is properly inserted into the
clamping ange.
6. Replace the blade guard and tighten it with the clamping
screw.
After the cutting shaft nut has been tightened on the opposite
side, the cutting shaft guard must be assembled.
DANGER!
Operation of the machine is not permitted
without saw blade guard and cutting shaft guard!
Diamond saw blades are designed to sharpen
themselves during operation (while cutting). However,
if cutting often into strong steel reinforcements or hard
material with low abrasion, they can become blunt. They can
be re-sharpened by cutting into abrasive material such as
limestone or asphalt.
ATTENTION!
Remove the diamond saw blade before transport to avoid
damaging the tool!

4.5 Connecting the water supply
The CEDIMA® joint cutter CF-22 E.800 is supplied with
water via a GEKA coupling.
The water shut-o valve located behind it allows you to
stop or reduce the supply of water.
Geka water coupling with shut-o valve Fig. 4.11
Only use water for cutting that is free of coarse impurities
to prevent blockages of the water supply.
ATTENTION!
Diamond tools designed for wet cutting mode must
never be operated without water! This also leads to an
inevitable loss of segments!
4.6 Electric connection
DANGER
Risk of injury due to electric short-circuit!
Never plug or unplug the power cable while the electric supply
is switched on or the saw blade drive motor (system under
electrical voltage) is running!
Lay the mains cable in such a way that there is no risk of
danger or damage and so that it cannot be pulled in or wound
up!
Do not expose the joint cutter to direct water jet and/or
extreme humidity! The joint cutter is splash-proof when
standing horizontally on its wheels! All electrical connections
must be kept free from moisture!
ATTENTION
Observe the corresponding safety precautions!

Joint Cutter CF-22 E.800
ATTENTION!
Make sure to establish electric connections properly!
Work on electrical supply lines and electric motors may
only be carried out by qualied electricians or by properly
instructed personnel under the direction and supervision
of aqualied electrician in accordance with the applicable
electrical engineering regulations!
Observe the valid national rules and regulations!
The connection must be established via a properly installed
socket with earthing contact!
The connection socket (CEE) must be fused by a residual
current circuit breaker (RCCB) conforming to standard! Only
that will ensure protective grounding and separation from the
mains as required for safety reasons!
In operation on construction sites, the connection to the
building site main cabinet must be established according to
IEC (EN) 61439 and 60364-7-704!
Observe the relevant safety regulations and standards for
operation of electric equipment, e.g. the directives of the
employer's liability insurance association DGUV 3 of the
BGHW and the standard EN 60204 part 1!
ATTENTION
Observe the risks when connecting to a current
generator!
If the joint cutter is connected to a current generator, the user
bears the risk in the event of defects, e.g. voltage uctuations!
When operating the CF-22 E.800 on a current generator, rst
switch the joint cutter OFF and disconnect it from the electrical
supply line and only then switch the current generator OFF!
Otherwise voltage surges can damage the electric system of the
joint cutter!
ATTENTION
Observe the specications when connecting
the mains cable!
The mains cable and the cable drum must be approved for the
connection values and for outside work!
Never connect the mains cable while it is still wound in the
cable drum because the heat resistance will cause power loss
of the joint cutter!
From 50m onwards, the joint cutter will show distinct
power loss!
From 100m cable length onwards, the power loss will
increase signicantly!
The power loss can be compensated to some extent by
selecting appropriate cable cross sections:
Recommended cable cross-sections:
up to 20 m -> 5 x 4mm²
up to 50 m -> 5 x 6mm²
up to 100 m -> 5 x 10mm²
