Trouble shooting, what if . . . ?
Joint cutter CF•22 E
Problem Possible cause
Remedy
The saw blade does not cut The saw blade is mounted backwards against the
direction of rotation
The saw blade is not matched to the material to be cut
(possibly it is too hard)
The saw blade is not matched to the machine power
output
Diamond segments are blunt
Mount the saw blade according to the direction of
rotation of the cutting shaft
Use the correct type of saw blade
Use the correct type of saw blade
Resharpen the saw blade
Cracks in the saw blade steel
core
The saw blade is too “hard” Use a“softer” saw blade
Cutting line is not optimal Poor saw blade tension (steel core)
The saw blade is overloaded
Diamond segments are blunt
Return the saw blade to the manufacturer
Reduce the feed rate (cutting depth)
Resharpen the saw blade
The saw blade has rotated on
the cutting shaft
Driving pin defective, missing Replace, insert the driving pin
The saw blade remains under
load
The V-belt is slipping
The V-belt is defective (torn)
Driving pin defective, missing
Tension the V-belt
Change the V-belt
Replace, insert the driving pin
The saw blade has become
coloured
The saw blade is overheated
The saw blade is subjected to excessive lateral friction
Optimise the cooling water feed
Reduce the feed rate
Do not tilt the saw blade in the cut
Chang points on the saw
blade
The feed direction is not parallel to the saw blade
The saw blade is overloaded
Poor saw blade tension
Do not tilt the saw blade in the cut
Reduce the advance speed
Return the saw blade to the manufacturer
Diamond segments show signs
of eccentric wear
The cutting shaft has shrunk
The mount for the saw blade is worn out (cutting shaft,
saw blade bore)
Excessive bearing play on the cutting shaft
Renew the cutting shaft
Turn out the saw blade mounting hole and adapt to the
correct diameter using aring
Replace the bearing or the cutting shaft
Areduced or no cooling water
ow
The water supply is not optimal
The water hoses are blocked, defective, come o, kinked
The shut-o valve is blocked, defective, not opened
Adapt the pressurised water supply
Clean the water hoses, check them, connect them,
replace them if necessary
Clean, check, open the shut-o valve; replace it if
necessary
The problems and their possible causes are mainly due to natural wear and to incorrect use of the joint cutter or the
diamond saw blades!
Therefore you should read this operating manual thoroughly!
