Set-up and operation

Joint cutter CF•22 E

4.2.3  Mounting the saw blade

Loosen and remove the cutting shaft nut with the SW 36 

spanner provided.

Cutting shaft               Pressure flange

nut

 

Figure 4.6

Remove the pressure flange.
Provide cleanliness of cutting shaft (thread) and blade 

flanges. 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).

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 flange 

on to the cutting shaft and tighten the cutting shaft nut 

securely! 
Make sure that the drive pin is properly inserted into the 

clamping flange!
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.
