BASIC DRILL PRESS OPERATIONS

Fig. U

SPEEDS AND BELT PLACEMENT (FIG. T)

This drill press has 5 speeds, as listed below:

540 RPM 880 RPM 1600RPM

2610 RPM 3600 RPM

To prevent the workpiece or backup material from being torn from your hands while drilling, you MUST position the workpiece against the LEFT side of the column. If the workpiece or the backup material is not long enough to reach the column, clamp them to the table, or use the fence provided with the drill press to brace the workpiece. Failure to secure the workpiece could result in personal injury.

USINGTHE FENCE (FIG. W)

The fence provides a way of accurately and quickly

setting up the workpiece for more precision or repetitive drilling operations.

See inside of the belt guard for specific placement of the belts on the pulleys to change speeds.

To avoid possible injury, keep guard closed, in place, and in proper working order while too! is in operation.

ON / OFF SWITCH (FIG. U)

The "ON / OFF" switch has a removable, yellow plastic key. With the key removed from the switch, unauthorized and hazardous use by children and others is minimized.

iNSTALLING DRILL BIT IN CHUCK (FIG. V)

1.With the switch "OFF" and the yellow switch key removed, open the chuck jaws (1) using the chuck key (2). Turn the chuck key counterclockwise to open the chuck jaws.

2.Insert the drill bit (3) into the chuck far enough to obtain maximum gripping by the jaws, but not far enough to touch the spiral grooves (flutes) of the drill bit when the jaws are tightened.

3.Make sure that the drill is centered in the chuck.

4.Turn the chuck key clockwise to tighten the jaws.

To avoid injury or accident by the chuck key ejecting

forcibly from the chuck when the power is turned "ON", use only the self-ejecting chuck key supplied with this drill

press. Always recheck and remove the chuck key before i = turning the power "ON".

1.Using the centerpunch or sharp nail, make an indentation in the workpiece where you want to drill.

2.Lower the drill bit to align with the indentation on the workpiece. See "HOLDING A DRILLING LOCATION" page t9.

3.Loosen the knobs (1) and slide the fence back stop (2) firmly against the long side of the workpiece. Tighten the knobs when in position.

4.Loosen the wing nut (3) and slide the end stop (4) along the fence until it is firmly against the left side of the workpiece. Tighten the wing nut.

5.Check the accuracy by drilling a scrap workpiece. Adjust if needed.

6.Hold with your hand or clamp the top surface of the

workpiece firmly to prevent it from lifting off the table when the bit is raised.

Fig. W

NOTE: With the chuck up, the tip of the drill bit must be just slightly above the top of the workpiece.

1.With the switch "OFF", turnthe feed handle until the pointer (7) points to the desired depth on the depth scale (4). Hold the feed handles in that position.

2.Spin the lower nut (3) down to contact the depth stop lug (6) on the head.

3.Spin the upper stop nut (5) against the lower stop nut and tighten.

4.The and drill bit will now stop after traveling the distance selected on the depth scale.

Drilling a hole

Using a center punch or a sharp nail, dent the workpiece where you want the hole. Before turning the switch on, bring the drill bit down to the workpiece, lining it up with the hole location. Turn the switch on and pull down on the feed handles with only enough effort to allow the drill to cut.

FEEDING TOO SLOWLY might cause the drill bit to turn. FEEDING TOO RAPIDLY might stop the motor, cause the belt or drill to slip, tear the workpiece loose, or break the drill bit. When drilling metal, it will be necessary to lubricate the tip of the drill bit with oil to prevent it from overheating.

t.To turn the drill press "ON", insert key (1) into the slot of the switch (2), and move tile switch upward to the "ON"

position.

2.To turn the drill press "OFF", move the switch downward.

3.To lock the switch in the "OFF" position, grasp the end, or yellow part, of the switch toggle, and pull it out.

4.With the switch key removed, the switch wili not operate.

5.if the switch key is removed while the drill press is running, it can be turned "OFF" but cannot be restarted without inserting the switch key.

Always lock the switch "OFF" when the drill press is not in use. Remove the key and keep it in a safe place.

tn the event of a power failure, blown fuse, or tripped circuit breaker, turn the switch "OFF'and remove the key, preventing an accidental startup when the power comes on.

DRILLING TO A SPECIFIC DEPTH

Drilling a blind hole (not afi the way through workpiece)

to a given depth can be done two w#ys:

Workpiece method (FIG. X and Y)

1.Mark the depth of the hole on tt_e side of the workpiece (1).

2.With the switch "OFF", bring the drill bit (2) down until the tip is even with the mark.

3.Hold the feed handle at this position:

4.Spin the lower nut (3) down to contact the depth stop lug (6) on the head.

5, Spin the upper	nut (5) down and tighten	against the	4
lower nut. (3)
6. The drill bit will	now stop after traveling	the distance
marked on the	workpiece.
