Joint Cutter CF-22 E.800
4.3.3 Mounting the saw blade
1. Loosen the clamping screw on the blade guard, then lilft
and remove it.

2. Loosen and remove the cutting shaft nut using the double
open-ended wrench supplied as an accessory.

3. Remove the air filter cover.
4. Make sure that the cutting shaft and the blade flanges 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).

5. Mount the diamond saw blade and the clamping flange
onto the cutting shaft and tighten the cutting shaft nut
securely.
Make sure that the drive pin is properly inserted into the
clamping flange.
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!
