Proper tension is important. This can be visually verified; you should see a slight
wave in the slack side of the wire during cutting (FIG. 11).
FIG. 11
Ending the cut
As you start to get close to the end of the cut, shim the cut with steel shims to
avoid pinching the wire during the cutting operation and when the cut is
complete. Ensure that pulleys are set up so they can catch the wire when it exits
the cut.
Troubleshooting
Problem Possible Cause Solution
Cable will not start Too much cable tension Reduce feed force
Cable thickness variation Check cable for uniform diameter
New cable in a narrow cut Open cut to clear wire
Hanging up on corner Round off edges
Cable locks up in cut Cable overloaded Reduce feed force
Hanging up on corner Round off edges
Cut not straight Not enough diverter pulleys Add more pulleys and check alignment
Cable too slack Increase feed force
Pulley misaligned or loose Check pulley alignment
Uneven wear Not enough pre-twist in wire Ensure that there is at least 1 twist for
every 3 feet.
Cable over tensioned Reduce feed force
Drive wheel and cable too close Increase spacing between saw and
pulley.
