height:
• Turn the switch to "OFF" position.
• Secure the workpiece to the drill table by using a scrap
piece of wood between the workpiece and clamp to
avoid damage to workpiece.
• Lower the drill bit by turning the feed handles until the
drill bit touches the workpiece.
Note: This sets the depth to zero at the surface of the
workpiece.
• Remove the workpiece and increase the depth of the
drill bit (past zero) until the desired depth is reached on
the dial.
• Hold in this position and lock the depth using the dial
lock.
• Knob to limit drilling depth.
• Using a clamping devise and reposition the workpiece to
the table.
