' Free blade guide head .The head is too far away
from the workpiece: move the
head closer, leaving free only
that part o f the blade actually
needed to make the cut
' Teeth in contact with the ma-
terial before starting the cut
.Always check the position of
the blade before starting a
new job, especially for the
semi--automatic cycle
' Widia inserts .If worn, the inserts can score
the blade, weakening it even
to breaking point. If the in-
serts are too far apart, the
blade will whip, striking both
the inserts and the material.
Replace or adjust
' Insufficient coolant .Check coolant fluid level;
clean pipes and jets
' Incorrect fluid concentration .Check and use the correct
concentration
' The blade stops in the cut .Cutting pressure too high:
check pressure an d reset to
rated pressure.

fast: reduce.
Head downstroke speed too
slow: increase.
The blade slips on the fly-
wheels: incorrect or low
blade tension; readjust or in-
crease.
