FAULT
Steaked or etched blades
Cuts off the straight
PROBABLE CAUSE
Damaged or chipped blade guide
pads
Tight or slackened blade guide
bearings.
Blade not parallel as to the counter
service
Blade not perpendicular due to the
excessive play between the guide
pads and maladjustment of the
blocks
Too fast advance
Worn out blade
Wrong tooth pitch
Brooken teeth
Insufficient lubricating refrigerant or
wrong emulsion

REMEDY
Replace them.
Adjust them (see Chapter "Machine
adjustments" in Blade guide section).
Check fastenings of the blade guide
blocks as to the counter-vice so that
they are not too loose and adjust
blocks vertically; bring into line the
position of the degrees and if
necessary adjust the stop screws of
the degree cuts.
Check and vertically re-adjust the blade
guide blocks; reset proper side guide
play (see Chapter "Machine
adjustments" In Blade guide section).
Decrease advance, exerting less
cutting pressure. Adjust the braking
device.
Approach it as near as possible to
material to be cut so that only the blade
section employed in the cut is free, this
will prevent deflections that would
excessively stress the blade.
Replace it. Blade with major density of
teeth is being used, try using one with
less teeth (see Chapter "Material
classification and blade selection" in
the Blade Types section).
Irregular work of the blade due to the
lack of teeth can cause deflection in the
cut; check blade and if necessary
replace it.
Check level of liquid in the tank.
Increase the flow of lubricating coolant,
checking that the hole and the liquid
outlet pipe are not blocked. Check the
emulsion percentage.
