• Pull the knob towards you and move it to the next or previous notch.

• Check the quill while feeding for smooth and unrestricted movement.

6. Usage

6.1 insTalling drills

Insert the drill into chuck jaws about 25.4 mm long. When using a small drill, do not insert it so far that the jaws

touch the flutes of the drill. Make sure that the drill is centered in the chuck before tightening the chuck with the key

(fig. 17).

6.2 posiTioning The work piece

Always place a piece of wood or plywood on the table. This will prevent "splintering" or making heavy burrs on the

underside of the work piece as the drill breaks through. The wood should make contact with the left side of the

column (fig. 18).

6.3 Using The vice

For small work pieces that cannot be clamped to the table, use a drill press vice. The vice must be clamped or bolted

to the table.
