SAW BAND STALLS DURING A CUT
1.
Decrease saw head feeding pressure.
2.
Increase band speed and/or head approach rate.
3.
Check for low hydraulic pressure.
4.
Check for pinching of saw band in the material due
to crooked stock. Use wider set saw band.
BLADE TOOTH GULLETS ARE LOADING
1.
Use a coarser pitch saw band.
2.
Increase the band speed setting, or decrease the
feed pressure setting.
3.
Check for improper coolant application.
4.
Check the positioning of the band brush. Replace
the brush, if necessary.
