1.  Observe chip formation to be sure cutting is efficient.
1.  Adjust guide bearings according to instruction in this
manual.
1.  Increase blade tension so blade does not slip on the
wheels.
1.  Move guide brackets until they just clear the workpiece
while making a complete cut.
2. For small section pieces, be sure the blade is sharp
and correctly tensioned.  Use less feed pressure.
1.  Replace blade when it dulls.
2.  Consider using a coolant, if not already used.
1.  Check technical literature for recommended speeds
and blade type for material being cut -- observe chip
formation to verify efficient cutting.
1. Tighten guide bracket.
1.  Check tightness of bearing seat bolt.
1. Use paper cutting method of setting blade tracking.

1.  Replace bearings if worn.
1.  Tighten all bolts securing wheel to arm.
1.  Try one step lower speed and observe chip formation
for efficient cutting/feed rate.
1.  Use finer blade.  Check with suppliers for recommen-
dations for  the material you are cutting.
1.  Check with blade suppliers for recommendations for
exotic or unusual materials or specifications.
1.   Be sure workpiece is flat on saw table.
2.  Decrease feed pressure.
1.  Reduce tension to just above point where blade slips.
1.  Check eccentric jam nuts for tightness.
1.  Check guide bearings for wear.  Replace if necessary.
1.  Adjust guide bearings according to instructions in this
manual.
1.  Tighten bracket on saw arm.
1.  Tighten bearing seat attachment screw -- adjust blade
for vertical and parallel.
1.  Replace.
1.  Check and adjust for proper clearance.
1.  Tighten bracket to saw arm.
1.  Adjust blade tracking using the paper cutting method.
1.  Use blade with finer pitch.
1.  Decrease feed rate -- observe chip formation to verify
efficient cutting.
1.  Increase blade speed.  Check technical literature or
blade or workpiece supplier for blade speed recommenda-
tions.
1.  Be sure vise is tight.
2.  Support slender cross section or long workpieces with
appropriate out-feed supports.
3.  If stacking pieces in the vise, be sure all workpieces
are securely captured by the vise.
1.  Use coarser blade or one with a tooth geometry more
appropriate to the workpiece being cut.
1.  Always allow motor to come fully up to speed before
beginning cut.
1.  Decrease blade tension to just above slip point.
1.  Use finer pitch blade.
1.  Use coarser blade.

1.  Replace gears in transmission gearbox.
1.  Check gearbox and add oil as required.
