Raise the
vertical quick-
adjustment nut.
High During automatic operation, verify that the blade can't
collide with the material while it initially lowers: raise
the vertical quick-adjustment nut. The blade can break
or stall when it drops from the raised position and then
collides with the part before the feed rate is controlled.
For more information, see "Use
Automatic Mode" (page38).
Use a different
blade.
High Verify that the blade's TPI isn't too high, or that the
material isn't too course: you must use the correct
blade for the material. If you're not, you may need to
choose a new blade.
For information, see "Choose a
Blade" (page30).
Adjust the feed
rate or cutting
speed.
High
l Verify that the feed rate isn't too high: lower the
feed rate, and then do a test cut. Examine the
behavior of the machine as it cuts.
l Verify that the cutting speed isn't too high: lower
the cutting speed, and then do a test cut.
Examine the behavior of the machine as it cuts.
For information, see "Change the
Feed Rate" (page34) or "Change
the Speed" (page34).
Examine the
workpiece setup.
Medium
l
Manual Operation Verify that the workpiece
isn't too loose: use the handwheel to tighten the
clamp on the front vise. If necessary, use a jig to
hold the workpiece.
l
Automatic Operation Examine the vise clamps:
verify that there is 1/8 in. or less of a gap
between the clamps and the material. Then,
verify that the vise jaw clamping pressure isn’t
set too low for the material.
For information, see "Use
Automatic Mode" (page38) or "Use
Manual Mode" (page42).
Adjust the
blade's tension.
Low Verify that the blade isn't too tight or too loose
between the wheels. If necessary, use the tensioner on
the top of the saw head to adjust the blade's tension.
For information, see "Change a
Blade" (page30).
Examine the
main power
supply voltage.
Low Test the hot lines to confirm that they have the correct
voltage on both legs.
For information, see "Electrical
Schematics" (page111).
Replace the
motor bearings.
Low Rotate the shaft: if there's rotational grinding or if the
shaft is loose, this indicates that you must replace the
motor bearings.
