Joint Cutter CF-22 E.800
5.7
Maintenance works
ATTENTION!
Observe the safety instructions in these operating
instructions!
ATTENTION!
Only use original parts!
The operational safety of the CF-22 E.800 is only guaranteed
when the original components (spare parts) are used!
5.7.1 Tensioning V-belts
To tighten the CF-22 E.800 V-belts, loosen the motor
fastening screws (Figure 5.1) slightly and pull the motor
back using the two clamping screws attached to the rear
of the motor. Check the V-belt tension constantly while
doing this. After completing this work, retighten the lock
nuts of the tensioning screws and the screws of the motor
mounting.

ATTENTION!
Tighten the nuts of the V-belt tensioning screws evenly!
Uneven tightening of the clamping screw nuts will cause the
motor mounting plate to jam and with it the motor and the
V-belt pulley on the motor shaft!
The V-belts will then slide off the edges of the V-belt
pulleys and wear out faster! A sudden crack with negative
consequences for the diamond saw blade, the motor, ...cannot
be ruled out in this case!
Note
To tighten the clamping screw nuts evenly, tighten them
alternately, one turn at a time!
– Check the V-belt tension (see section 4.1.3)!
5.7.2 Replacing the V-belt
The V-belts should or must be replaced when another
tensioning is not possible any more and/or the V-belts
are damaged (frayed, porous, ...)!
DANGER!
Risk of pinching and crushing!
Careful with hands and fingers when replacing
the V-ribbed belt.
Note
The V-belts should be changed together to ensure uniform
tensioning and power transmission!
1. Lift out the cutting shaft (saw blade).
2. To replace the CF-22 E.800 V-belts, first remove the blade
guard or the cutting shaft cover, depending on cutting
side (right or left) (Fig. 4.3).
3. Remove the V-belt guard; the V-belt drive is exposed.

4. Release the tension of the V-belts as described in
section 5.7.1, remove the old V-belts and install the new
V-belts!
5. Tension the cutting shaft V-belts as described in
section 5.7.1.
