guide. Raise the blade guide as high as it will go. Turn
the lock knob clockwise to retighten.
 Loosen the table lock knobs slightly.
 Tilt the saw table toward the front of the saw housing

 Using the scale indicator, check angle markings.
 Retighten the table lock knobs to hold saw table securely

CIRCLE CUTTING
See Figure 32, page 30.
 Adjust the upper guides to vertically just clear the
workpiece.
 Use both hands while feeding the work into the blade.
Hold the workpiece firmly against the table. Use gentle
pressure, and do not force the work, but allow the blade
to cut.
 The smallest diameter that can be cut out is determined by
the width of the blade. For example, a 1/4 in. wide blade
will cut a minimum diameter of approximately 1-1/2 in.
 From arm's length, carefully uncoil the new blade. If the
new blade was oiled to prevent rusting, it may need to be
wiped to keep the oil off the workpiece. Carefully wipe in
the same direction the teeth are pointing so the rag does
not catch on the teeth of the blade.
 With the teeth of the blade toward the left of the saw
and facing downward, place the blade through the blade
guides and around both wheels.
 Slowly turn the upper wheel to the right or clockwise by
hand to center the blade on the rubber tires.
 Turn the blade tension knob clockwise to tension
the blade. See Assembly section "Adjusting Blade
Tension".
 Adjust the tracking of the blade. See Assembly section
"Tracking the Blade".
