Manual Operation
Use the horizontal slider to move the spindle over to the starting position. The starting position is just
before the cutterhead guard passes over the work piece. Use the vertical slider and position buttons to
get the cutter head close to the proper cutting position. Push the dial depth indicator, on the guard, down
onto the top of the work piece. Assuming the dial indicator has been properly adjusted (see the
Maintenance chapter of this manual for adjustment instructions) it will indicate the depth of the cut at your
current height setting.
Press the up or down vertical move buttons to adjust the depth of the cut. Enter the Feed Rate value and
Spindle RPM value for the desired finish. Press the SPINDLE START button and the FEED LEFT button.
The machine will start Feeding across the work piece.
When the machine has finished cutting, press the START SPINDLE travel button to stop the machine.
Use the vertical slider to raise the spindle up, then horizontal slider to move the carriage back to the
home position.
