SYMPTOM POSSIBLE CAUSE(S) CORRECTIVE ACTION
Blade breakage/damag Blade guide pads not adjusted properly
or dirty because of lack of maintenance
Check the adjustment of the blade guides.
See OPERATION SET-UP / Blade guide insert
adjustments on page 7. Extremely tight tolerance
guiding may cause cracks and breakage of teeth.
Use extreme care when cleaning.
Blade guide block too far from material to
be cut
Set the left blade guide arm closely to the material
being cut so that only the blade section used in
the cut is free, this will prevent deflections that
stress the blade,
Improper position of blade on flywheels
The back of blade rubs against the support due
to deformed or poorly welded bands (tapered),
causing cracks and swelling of the back contour.
Replace the defective blade with a new one.
Insufficient lubricating coolant or wrong
emulsion
Check level of lubricating coolant level in the tank.
Increase the flow of lubricating coolant, checking
to ensure the hole and the liquid outlet pipe are
not blocked. Check the emulsion percentage.
Blade cuts crooked Blade not parallel in relation to the
counter vise
Check the blade guide blocks to ensure they are
fastened tightly to the counter vice. Adjust the
blocks vertically and if necessary adjust the stop
screws of the degree cuts.
Blade not perpendicular due to the ex-
cessive play between the guide pads
and misalignment of the blocks
Check and adjust the blade guides for proper
tolerances. See OPERATION SET-UP / Blade
guide insert adjustments on page 7.
Cut advancing too fast
Decrease the speed of the cut advance, exerting
less cutting pressure. Adjust the braking device.
Worn out blade
Move the blade close to material being cut so that
only the blade section used in the cut is free, This
will prevent deflections that would excessively
stress the blade. Replace the blade.
Wrong tooth pitch
Replace blade choosing the proper tooth pitch.
See OPERATION - BLADE SELECTION
GUIDE LINES page 9.
Broken teeth
The lack of teeth can cause deflection during the
cut; check the blade for broken teeth and replace
it if necessary.
Insufficient lubricating coolant or wrong
emulsion
Check level of lubricating coolant level in the tank.
Increase the flow of lubricating coolant, checking
to ensure the outlet hole on the left blade guide
arm and the liquid outlet pipe are not blocked.
Check the emulsion percentage.
Streaked or etched bands Damaged or chipped blade guide pads Replace the blade guide pads.
Tight or loose blade guide bearings
Correctly adjust the guide bearings. See
OPERATION SET-UP / Blade guide insert
adjustments on page 7.
