Faults and troubleshooting – CF-22 E.800
What if ...
Problem
Possible cause
Remedy
Diamond segments become
detached
Saw blade too hot
Solder diamond sections on again
Adjust the cooling water supply
Excessive diamond segment
wear
Incorrect saw blade type
Cutting shaft is bent
Saw blade too hot
Use harder saw blade type
Replace bearing and/or cutting shaft
Adjust the cooling water supply
No output when cutting,
saw blade not cutting
Saw blade mounted against direction of rotation
Saw blade not adjusted to the material to be cut
(possibly too hard)
Saw blade not matched to the machine
performance
Diamond segments are blunt
Mount saw blade according to the cutting shaft direction of
rotation
Use correct saw blade type
Use correct saw blade type
Sharpen the saw blade
Cracks in steel core of saw
blade
Saw blade is too hard
Use a "softer" saw blade
Cutting line is not optimal
Bad saw blade tension (steel core)
Saw blade is too heavily loaded
Diamond segments are blunt
Return saw blade to manufacturer
Reduce the feed (cutting depth)
Sharpen the saw blade
Saw blade has rotated on the
cutting shaft
Driver pin defective, missing
Replace, insert driver pin
Diamond saw blade stops
under load
V-belt slips
V-belt defective (torn)
Driver pin defective, missing
Tensioning V-belts
Replace V-belts
Replace, insert driver pin
Saw blade is discoloured
Saw blade got too hot due to insufficient
cooling water
Side friction of saw blade too high
Adjust the cooling water supply
Reduce the feed
Do not tilt saw blade in the cut
Chafe marks on the saw blade Feed line not parallel to saw blade
Saw blade is too heavily loaded
Bad saw blade tension
Do not tilt saw blade in the cut
Reduce the feed
Return saw blade to manufacturer
Eccentric wear on the
diamond segments
Cutting shaft has shrunk
Support of the saw blade is worn out
(cutting shaft, saw blade hole)
Too much bearing play of the cutting shaft
Replace cutting shaft
Turn the saw blade location bore and let a ring be fit in
Replace bearing or cutting shaft
Low or no cooling water flow
Water supply sub-optimal
Water hoses clogged, defective, off, kinked
Shutoff valve clogged, defective, not open
Adapt the pressurized water supply
Clean, check, connect or replace water hoses
Clean, check, open or replace shutoff valve
The problems and their possible causes are mostly a result of natural wear and tear and in the incorrect handling of the
joint cutter or the diamond saw blade)!
Therefore you should read this operating manual thoroughly!
