FAULT

PROBABLE CAUSE

REMEDY

Check distance between pads (see “Ma-
chine adjustments” in the

Blade Guide

Blocks section): extremely accurate guid-
ing may cause cracks and breakage of
the tooth. Clean carefully.

Approach head 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 exces-
sively stress the blade.
The back of blade rubs against the sup-
port due to deformed or poorly welded
bands (tapered), causing cracks and
swelling of the back contour.
Check level of liquid in the tank. Increase
the flow of lubricating refrigerant, check-
ing that the hole and the liquid outlet pipe
are not blocked. Check the emulsion per-
centage.

Replace them.

Adjust them (see Chapter “Machine ad-
justments” 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 verti-
cally; 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 mate-
rial to be cut so that only the blade sec-
tion 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 sec-

tion).

Blade guide pads not regulated or dirty
because of lack of maintenance

Blade guide block too far from mate-
rial to be cut

Improper position of blade on fly-
wheels

Insufficient lubricating refrigerant or
wrong emulsion

Damaged or chipped blade guide
pads
Tight or slackened blade guide bear-
ings

Blade not parallel as to the counter-
vice

Blade not perpendicular due to the
excessive play between the guide
pads and maladjustment of the blocks

Too fast advance

Blade guide block too far from mate-
rial to be cut

Worn out blade
Wrong tooth pitch

STREAKED OR ETCHED BANDS
