Joint cutter CF•22 E
7.0 Troubleshooting at the joint cutter CF•22 E
7.1
Problems when starting (engine)
7.2
Problems when cutting
Problem
Possible cause
Remedy
The motor does not start
The network cable is not attached properly
Network cable, plug connector, socket defective
Star-delta reversing switch is defective
Loosened electric connection in the electric system
The motor is defective
Cutting shaft blocked,
cutting shaft with the saw blade not lifted from the
ground or out of the cut
The power network fuse(s) have triggered
The motor has not yet been cooled off after overloading
Attach the network cable properly
Check the network cable, plug connector, socket and
replace it if necessary
Check the star-delta switch and replace it if necessary
Have the complete electrical system checked by an
electrician
Check the motor and replace it if necessary
Check for ease of movement of the cutting shaft
lift the cutting shaft (saw blade) from the ground, out of
the cut
Remove the fault, reset the fuses
Leave the motor to cool down
No power available when
cutting,
The network cable is the wrong size, too long,
cable drum coiled up
The power supply network is not adequate
Star-delta reversing switch not “started through”, motor
in still in Y-mode
The motor does not maintain its rotational speed
Connect the respective network cable, keep the network
cable as short as possible, roll off the cable drum
Comply with specified connection values
Bring the star-delta switch further into the ∆ position
Check the motor, repair it / replace it if necessary
The motor has stopped
Too high cutting pressure (overload protection)
Motor overload switch defective
Damage in electrical system
Reduce the cutting pressure (feed rate, cutting depth)
resp. have the motor cooled down with freely rotating
saw blade
Have the switch checked by an electrician and, if
necessary, replace it
Have the electrical system checked by an electrician
Problem
Possible cause
Remedy
Cutting blade wobbling
Diamond saws flange(s) is/are dirty, and/or defective
The cutting shaft nut has come loose
Poor saw blade tension
Clean the diamond saw flange, check it and replace it if
necessary
Tighten the cutting shaft nut
Return the saw blade to the manufacturer
The saw blade has side and/or
radial run-out
The saw blade is damaged, bent
The diamond saws flange(s) is/are dirty, and/or defective
The cutting shaft is bent and/or the bearing is defective
Have the saw blades realigned
Have the diamond segments resoldered onto a new
blade core
Use a new saw blade
Clean the diamond saws flange(s), replace
Replace the cutting shaft and/ or bearing
Diamond segments come loose The saw blade is overheating
Resolder the diamond segments
Optimise the cooling water feed
Excessive diamond segment
wear
The wrong type of saw blade is/are being used
The cutting shaft is bent
The saw blade is overheated
Use a harder type of saw blade
Replace the bearing and/or cutting shaft
Optimise the cooling water feed
