Maintenance and care
Joint cutter CF•22 E
5.7 Maintenance work
ATTENTION!
Observe the safety instructions of this operating manual
and all safety notes of attachments supplied with the
joint cutter!
ATTENTION!
Only use genuine parts!
Only by using genuine parts or parts (spare parts) approved
by CEDIMA® the operational safety of the CF•22 E can be
guaranteed.
5.7.1 Adjusting the tension of the V-belts
For tensioning the V-belts slightly loosen the two motor x-
ing screws (g. 5.1). Pull the motor backwards with the helb
of the two tensioning screws mounted on the rear side of
the motor. While doing this, check the tension of the belts.
After the correct belt tension has been achieved, retighten
the lock nuts of the tension screws and the motor xing
screws.

Motor xing screws
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 conse-
quences for the diamond saw blade and the motor cannot be
excluded!
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 chang-
ing 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.
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 V-
belts 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!
