PREMATURE BLADE BREAKAGE
1. Poor weld in the blade.
2. Feed rate set too high. Reduce it.
3. Excessive blade speed. Adjust it.
4. Blade guides set too tight or misaligned.
5. Blade tension set too high.
6. Blade running against fl ange on wheels.
Adjust wheel pitch.
BLADE SQUEAL
1. Feed rate too light for blade speed. Increase feed
rate and/or reduce blade speed.
BLADE SLIPS OFF BAND WHEELS
1. Blade not tensioned correctly.
2. Wheel pitch not set properly.
3. Guides set too tight.
GULLETS OF BLADE TEETH LOADING
1. Blade pitch too fi ne. Review blade selection.
2. Incorrect blade speed. Consult cutting chart.
3. If not using coolant, apply it.
CHIPS WELDING TO BLADE TEETH
1. Cutting rate too high.
2. Chip brush may be out of adjustment.
3. Check coolant and application.
BLADE BECOMING SCORED
1 . Saw guides may be worn. Check and replace if
necessary.
2. Too much pressure on saw guides. Adjust.
3. Guides may be out of alignment.
BLADE MAKING BELLY-SHAPED CUT
1. Blade tension too light. Increase it.
2. Saw guides too far from work piece.
3. Blade pitch too fi ne. Use larger pitch and positive
rake tooth form.
4. Feed force too heavy. Decrease it.
INACCURATE CUT-OFF
1. Is conveyor or stock stand level with saw bed?
2. Insuffi cient blade tension.
3. Blade guides too far apart. Always set blade guides
as close to the piece as possible.
4. Blade may be dull. Check and replace if necessary.
5. Feed pressure too high. Reduce it.
6. Blade guides loose, worn or out of alignment.
7. Too many teeth-per-inch. Blade not cutting freely.
8. Chip brush not cleaning teeth properly.
9. Dirty coolant.
10. Check for loose fasteners.
ROUGH CUT / POOR FINISH
1. Excessive feed rate. See recommendations.
2. Blade too coarse. Use fi ner blade pitch.
3. Inadequate cutting fl uid. Replace.
BLADE STALLS IN WORK
1. Insuffi cient blade tension.
2. Excessive feed pressure.
3. Blade tooth spacing too coarse.
4. Motor worn or defective.
5. Guides too tight against blade.
BLADE DOES NOT TRACK PROPERLY
1. Set wheel pitch so that blade runs to wheel fl ange
but not against it.
2. Is blade tension correct?
3. Is back of blade riding against backup bearing? If
not, adjust it.
AUTOMATIC STOP
When the blade has completed a cut through the mate-
rial, the saw frame drops onto a limit switch actuator
which shuts the motor off.
When changing a blade or doing any other maintenance
or repair, be sure the automatic stop is engaged and
disconnect the main power supply.
It is necessary to raise the saw frame to clear the limit
switch actuator before the saw can be started.
