the chuck jaws so that the opening is slightly larger than
the bit size you intend to use.

ADJUST DRILL DEPTH
Refer to Figure 16
Two ways to adjust the drill depth to the desired height:
• Loosen the lock knob.
• Rotate depth gauge to the desired setting.
• Retighten the lock knob securely.
The other way to adjust the drill depth to the desired
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.
• Turn on the tool and drill to the desired depth.
