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•22E at
workplaces dicult to access.
Assembly and dismantling of the subassemblies is done in just a few steps, no extra tools are necessary.
Figure 2.1
The weight distribution resulting from the arrangement
of all the components of the CF•22 E on this joint cutter
means that sucient 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.

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 alockable hand crank with
athreaded spindle.
By using the innite 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 aline.
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 aGeka coupling
The drive unit and cutting shaft rpm are designed in such
away that they create the optimal conditions for cutting
with CEDIMA® diamond saw blades.
We recommend the CEDIMA® diamond saw blades as
acutting insert since they achieve preservation of the joint

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 material 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 %!

4.2.3 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 comply 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).
Diamond tail
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 opposite 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 armouring or in hard material, which is only slightly abrasive.
Blades can be re-sharpened by cutting in an abrasive material 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 unintentionally, set the cutting shaft to the highest position
using the hand crank.
In this position, the left rear wheel is blocked.

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 rotating immediately!
The joint cutter should only be moved to the operating
area when the saw blade is at standstill!

Observe specications 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 compensated 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

Motor xing screws
NOTE
An even tightening of the clamping nuts can be obtained by
turning the nuts alternately each one turn!
– Check the tension of the V-belts (refer to section 4.1.3).
5.7.2 Changing the V-belts
The V-belts should and/or have to be replaced, when
further tensioning is no more possible and when they are
damaged (frayed, porous, …).
DANGER!
Risk of jamming and crushing during changing of the V-belts! Watch out for hands and
ngers!
NOTE
The belts shoud always be changed together, so a equally
tensioning and power transfer is possible.
Depending on the right or left cutting side, dismantle the
blade guard or the cutting shaft protection rst (g. 4.3).
After dismounting the V-belt cover (g. 4.3) the V-belt drive
is exposed.
Relax the V-belts as described in sect. 5.7.1, remove the old
belts and place the new.
Tighten the cutting shaft V-belts and mount the V-belt
cover and the blade guard resp. cutting shaft protection.
Clamping nut Lock nut
Figure 5.1
ATTENTION!
Tighten the nuts of the clamping screws evenly!
Unevenly tightened clamping nuts might lead to canting of
the motor suspension plate and consequently of the motor
and V-belt pulleys on the motor shaft.
The V-belts are running at the edges of the V-belt pulleys and
wear more quickly. A sudden rupture with negative consequences for the diamond saw blade and the motor cannot be
excluded!
ATTENTION!
Do not use any sharp or pointed objects for changing the
V-belts in order to prevent damages that might destroy
the V-belts.
NOTE
Turn the pulleys of the cutting shaft and the motor and move
the V-belts diagonally across the pulley grooves until all Vbelts are parallel.
ATTENTION!
Do not overstretch the V-belts (1,5% wear limit)! The
V-belt can break and the cutting shaft bearings and
motor bearing will be destroyed otherwise.
ATTENTION!
New V-belts have to be checked for correct tension and,
if necessary, be retensioned at least after 10 operating
hours!
