Equivalent total vibration rating ahv, eq < 2,5 m/s²
Measurement uncertainty K m/s²
The given values can vary as they depend on the application conditions (the material that has to be cut, the state of the
machine, handling, the operator and the diamond tools being used, etc.).
The actual period of exposure, which can be considerably aected by the non-productive times (reduced), must always be
taken into consideration when determining the daily vibration load A(8) as per DIN EN ISO 5349-2. The following count as
non-productive times: time needed for relling with fuel, dealing with the water supply, changing the tools, setting up and
moving the machine, etc., as well as securing the workplace, the area of operation.
Uncertainties in measurement according to DIN EN 12096.
Aparameter calculator for determining the daily vibration rating (daily vibration load A(8)) can be found on the internet
e.g. The German Accident Insurance (DGUV) and/or the Trade Association sites (BG).

Description of the joint cutter CF•22 E
2.0 Joint cutter CF•22 E
The electrically driven CF•22 E is intended to be used as joint cutter / ground parting-o grinder for wet cutting, using
diamond saw blades. In places where due to exhaust and/or noise protection regulations machinery with internal
combustion engines cannot be used (e.g. closed rooms).
In spite of the compact design the CF•22 E can achieve a cutting depth of 270 mm and thus allowing more demanding
cutting works.
The construction in 3 easily transportable modules enables trouble-free transport and the assembling of the CF•22E at
workplaces dicult to access.
Assembly and dismantling of the subassemblies is done in just a few steps, no extra tools are necessary.
Figure 2.1
Separated in modules Figure 2.2
The weight distribution resulting from the arrangement
of all the components of the CF•22 E on this joint cutter
means that sucient pressure is applied to the diamond
saw blade, at the same time making the machine easy to
handle when setting it up and repositioning.
The modular design facilitates cleaning, maintenance and
if necessary the repair.

Description of the joint cutter CF•22 E
The cutting shaft with the diamond saw blade is driven by
amodern, powerful electric motor over aV-belt.
The blade mounting is right or lef possiblet. For this pur-
pose the blade guard mounting side must be changed.
The feed is performed manually by pushing on the adjusta-
ble push handle.
Lowering and raising the diamond saw blade takes place
exactly and quickly over alockable hand crank with
athreaded spindle.
By using the innite cutting depth adjustment it is possible
to achieve cutting depths of up to 270 mm.
The cutting shaft is mounted in two selfaligning pedestal
bearings. The precision-engineered shaft has a 25.4 mm
diameter blade mounting ange.
The front pointer, which is mounted on the joint cutter
frame, enables the user to cut accurately along aline.
The water supply of the saw blade occurs over pressurised
water from an external hose which is to be connected to
the shut-o valve using aGeka coupling
The drive unit and cutting shaft rpm are designed in such
away that they create the optimal conditions for cutting
with CEDIMA® diamond saw blades.
We recommend the CEDIMA® diamond saw blades as
acutting insert since they achieve preservation of the joint
cutter due to their cutting capacity and smooth running

4.2 Mounting the diamond saw blade
4.2.1 General information on mounting
The drive unit of motor and cutting shaft RPM are designed
to provide optimal conditions for cutting with CEDIMA®
diamond saw blades!
Choose the right kind of diamond saw blade for the mate-
rial to be cut!
Observe the diameter of the shaft hole (spindle diameter)
and of the cutting shaft.
Please refer also to chapter “technical data and accessories”.
If the shaft hole diameter of your saw blade is larger, use an
appropriate reducing ring!
The maximum permissible saw blade diameter is 700 mm!
Detailed information about the proper saw blade types and
reducing rings are to be obtained from CEDIMA®!
CEDIMA® can not accept any warranty in case of incorrect
use of diamond saw blades!
Complaints concerning diamond saw blades supplied by
CEDIMA® can only be accepted if the diamond segments
show a minimum remaining segment height of 20 %!
4.2.2 Lifting the cutting shaft
DANGER!
Make sure that the joint cutter can not be
started unintentionally by isolating the motor
from the power supply!
Loosen the star-knob screw which locks the lifting spindle.
Turn the spindle by means of the hand crank until the
blade arm reaches its maximum height. At the same time
the machine is braked by the stopper.

4.2.3 Mounting the saw blade
Loosen and remove the cutting shaft nut with the SW 36
spanner provided.
Cutting shaft Pressure ange
nut Figure 4.6
Remove the pressure ange.
Provide cleanliness of cutting shaft (thread) and blade
anges. Remove any dirt with a lint-free cloth.
The direction of rotation of the cutting shaft has to com-
ply with 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.
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).
Segment
Diamond tail
Direction of rotation Figure 4.7
DANGER!
Check the sense of rotation of the diamond
saw blade, its true running and make sure it is
undamaged!
Before mounting the saw blade check it for possible dam-
ages.
Any damages/missing diamond segments as well as untrue
running exclude the use of the saw blade.
Mount the diamond saw blade and the clamping ange
on to the cutting shaft and tighten the cutting shaft nut
securely!
Make sure that the drive pin is properly inserted into the
clamping ange!
Replace the blade guard and tighten it with the clamping
screw.
After the cutting shaft nut has been tightened on the op-
posite side the cutting shaft protection must be assembled.
DANGER!
Using the joint cutter without the blade guard
is not allowed!
Diamond saw blades are designed to re-sharpen
themselves during cutting operation. They can be-
come blunt by frequent cutting in heavy steel armour-
ing or in hard material, which is only slightly abrasive.
Blades can be re-sharpened by cutting in an abrasive mate-
rial such as chalky sand stone or asphalt!
ATTENTION!
Operating the joint cutter without blade cover is not
allowed!
4.3 Aktuate the parking brake
To park the machine and prevent it from rolling away un-
intentionally, set the cutting shaft to the highest position
using the hand crank.
In this position, the left rear wheel is blocked.

At strongly sloping terrain the machine must be addition-
ally secured against rolling away.
Replace a worn stopper in time to preserve the braking
eect.
4.4 Adjusting and using the front pointer
The front pointer is adjustable mounted on the rocker with
motor of the joint cutter.
When fold down it allow the operator to cut precisely along
a marked line.
Alignment of the pointer is carried out with the motor
stopped and with the diamond saw blade tted.
If the pointer has been knocked out of adjustment or bent
during transportation, it can be realigned as shown in the
illustration below.

4.5 Connecting the water supply
The joint cutter CF•22 E is provided with water via a GEKA
coupling.
The water shut-o valve which is located behind, permits
to stop or reduce the supply of water.
GEKA-water connection shut-o valve Figure 4.11
Only use water which is free from coarse pollution (free of
solids, clean) to prevent blockage of the cooling system!
ATTENTION!
Cutting tools which are designed for the wet-cutting
mode only, may never be operated without water! Loss of
segments will inevitably be the consequence!
4.6 Starting the motor
DANGER!
When starting the engine, the cutting shaft
with any mounted saw blade will start rotat-
ing immediately!
The joint cutter should only be moved to the operating
area when the saw blade is at standstill!
Transporting and moving the joint cutter with the saw
blade rotating freely is forbidden!
Ear protection must be worn!
To start the motor in safety, lift the diamond sawing blade
from the surface to be cut (resp. out of the cut) by turning
the crank 2 turns by hand.
The motor is started via the star-delta reversing switch on
the control box.
Before starting, connect the power supply to the electric
motor. Make sure that you obey the relevant safety provi-
sions for the operation of electrical machinery.

ATTENTION!
Connect the electrical connections properly!
Working on electrical mains and electric motors
may only be carried out by electricians or by persons under the
supervision of electrical specialists according to the electro-
technical rules. Observe the specic rules and regulations of
the country in question!
For use on a construction site, the connections must be on a
power supply according to IEC (EN) 61439 und 60364-7-704 a
building site power supply!
Pay attention to the relevant safety information for operating
electrical systems, e.g. DGUV 3 of BGHW, the respective VDE
specications and the relevant measuring (standard) e.g. EN
60 204-part 1!
ATTENTION!
Observe specications for connecting the mains power
supply cable!
The mains power supply cable, the cable drum must be
according to the connected values and be released for the
outer area!
Never connect with the mains power supply cable wound onto
the cable drum since power losses can occur on the joint cutter
due to the heat resistance!
From a cable length of 50 m losses in performance arise on the
joint cutter!
From a cable length of 100 m losses in performance increase
strongly!
The losses in performance can be almost completely compen-
sated for by using appropriate cable cross sections:
Pay attention to the cross-section equivalent to the lengths of
the electric connections:
up to 20 m –> 5 x 4 mm²
up to 50 m –> 5 x 6 mm²
up to 100 m –> 5 x 10 mm²
