Use and Care Manual

OPERATION

BELT TENSION ADJUSTMENT

For proper belt tension: Use 10 lbs pressure or hand pressure on the belt as shown below. The distance is

1/2” (13mm)+10%.

INSTALLING DRILL BIT

Insert bit into chuck jaws about 1” (25mm). When using a small bit do not

insert it so far that the jaws touch the arbor of the drill. Make sure that the bit

is centered in the chuck before tightening the chuck with the key

(Fig. 14)

DRILLING

Use clamps to hold the work when drilling. The work should never be held in the bare hand, the lips of the

drill may seize the work at any time especially when breaking through the stock. If the piece is whirled out

of the operator’s hand, injury may occur. Also, the drill bit will be broken when the work strikes the column.

The work must be clamped rmly while drilling. Any tilting twisting or shifting results not only in a rough hole,

but also increases drill breakage. For at work, lay the piece on a wooden base and clamp it rmly down

against the table to prevent it from turning.

Using Vise

For smaller workpiece that cannot be clamped to the table, use a drill press vise (not included). The vise

must be clamped or bolted to the table.

Positioning Workpiece

Always place a piece of wood (or plywood) on the table,

this will prevent “splintering” or making heavy burrs on the underside of the

workpiece as the drill breaks through. The wood must contact the left side of

the column (Fig. 15).

Morse Taper Drill Bits

To use Morse taper bits remove chuck and taper. To remove taper and chuck

adjust stationary depth to 3” (75mm) (see depth instructions). Turn spindle

manually lining up spindle and quill key hole.

Place the wedged end of the cotter in the quill key hole and lightly tap until

the arbor and chuck fall out. Place tapered bit into the spindle hole, twist and

push upwards until bit is snug, place a block of wood on the table and crank

up table until the tapered bit is rmly into the spindle.

Round-Out Tolerance

For drilling operations requiring close tolerances, place drill blank in the chuck and check round out with a

dial indicator if the round-out is not within desired tolerance, tap the chuck bottom with a drubber or leather

mallet until you get the desired tolerance.
