OPERATION
 Turn the material over and make the cut along one of the
marks. This time overcut the other line and the cut piece
should separate from the rest of the material.
 When the second cut is made, turn the saw OFF. Wait
for the cutting wheel to come to a complete stop before
removing any part of the material.
TO MAKE A BEVEL CUT
See Figure 40.
Beveled cuts can be made from 0° to 45° angles. The saw
will seat itself in one of the 0°, 22.5°, or 45° index points.
 Using a marker or grease pencil, mark the area to be cut
on material.
 Loosen the bevel lock lever and move the saw arm to the
desired bevel angle.
 Retighten the bevel lock lever.
 Set the miter guide to the desired setting, lock in place,
and tighten the lock knob.
 Make sure the material is clear of the cutting wheel before
turning on the saw.
 Turn the on/off switch to the ON position.
 Turn the flow adjustment valve to the ON position.
 Let the cutting wheel build up to full speed and wait for
the wheel to get wet before moving the material into the
wheel.
 Hold the material firmly against the miter guide and fence
and feed the material into the cutting wheel.
 When the cut is made, turn the saw OFF. Wait for the
cutting wheel to come to a complete stop before removing
any part of the material.
TO MAKE A PLUNGE CUT
See Figure 41.
Plunge cuts are made by positioning the material directly
underneath the cutting wheel and lowering the wheel onto
the workpiece. This allows pieces to be cut from the center
of the material.
 Using a marker or grease pencil, mark the area to be cut
on material.
 Push down on the "D" handle and pull out the lock pin.
 Loosen the lock knob on the side of the motor head and
position the motor head upward to its maximum height.
 Set the miter guide to the desired setting, lock in place,
and tighten the lock knob.
 Turn the on/off switch to the ON position.
 Turn the flow adjustment valve to the ON position.
 Let the cutting wheel build up to full speed and wait for
the wheel to get wet before moving the material into the
wheel.
 Hold the motor head firmly by the handle.
 Move the material into the desired position for cutting.
 Slowly lower the motor head into the material to make
the cut.
 Raise the motor head.
 Turn the on/off switch to the OFF position.
 Turn the flow adjustment valve to the OFF position.
 Slide the table away from the motor head and position
the work material for the next cut.
