Symptom
Possible Cause
Incorrect coolant or no coolant.
Premature blade
dulling. (cont.)

Crooked cuts.
Work not square.
Feed pressure too great.
Guide bearings not adjusted properly.
Inadequate blade tension.
Blade guides incorrectly spaced.
Dull blade.
Incorrect speed.
Blade guide assembly loose.
Blade guide bearing assembly loose.
Blade tracking too far away from wheel
flanges.
Worn upper wheel bearings.
Loose upper wheel mounting assembly.
Rough cuts.
Too much feed or speed.
Blade too coarse.
Incorrect blade for material.
Blade twisting.
Cut is binding blade.
Too much blade tension.
Loose guide bearing eccentrics.
Worn guide bearings.
Correction
Check with materials supplier and/or blade
supplier for coolant recommendations.
Check with coolant supplier for specific
recommendations on the blade and material
you are using.
Increase tension so blade is above the slipping
point.
Adjust the right vise jaw so it is at right angles
to the blade.
Clamp work tightly in the vise.
Check blade for vertical and adjust, if
necessary.
Move guide bearings as close as possible to
work while still completing the cut.
Check guide bearings, seats and brackets for
possible looseness or wear.
Observe chip formation to be sure cutting is
efficient.
Adjust guide bearings according to instructions
in this manual.
Increase blade tension so blade does not slip
on the wheels.
Move guide brackets until they just clear the
work piece while making a complete cut.
For small section pieces, be sure the blade is
sharp and correctly tensioned. Use less feed
pressure.
Replace blade when it dulls.
Consider using a coolant, if not already used.
Check technical literature for recommended
speeds and blade type for material being cut –
observe chip formation to verify efficient
cutting.
Tighten guide bracket.
Check tightness of bearing seat bolt.
Use paper cutting method of setting blade
tracking.
Replace bearings if worn.
Tighten all bolts securing wheel to arm.
Try one step lower speed and observe chip
formation for efficient cutting/feed rate.
Use finer blade. Check with suppliers for
recommendations for the material you are
cutting.
Check
with
recommendations
materials or specifications.
Be sure work piece is flat on saw base.
Decrease feed pressure.
Reduce tension to just above point where
blade slips.
Check eccentric jam nuts for tightness.
Check guide bearings for wear. Replace if
necessary.
