2. Loosen the belt tension knobs (2) on the right side of the
drill press head.
3. Pull the motor (3) toward the drill press head.
4. Set the belt (6) on the desired steps of the motor (4) and
spindle (5) pulleys according to the belt positions on the
Spindle Speed Chart (fIG 7).
5. Push the motor away from the drill press head to
increase the belt tension. Tighten the tension knob (2).
6. The belt (4) should be tight enough to prevent slippage.
Correct tension is set if the belt flexes about 1/2" when
thumb pressure is applied at the midpoint of the belt
between the pulleys.
Adjusting Table Height (FIG 8)
1. Loosen the table lock handle (1).
2. Slide the table assembly (2) to the desired height.

Adjusting Table Bevel (FIG 8)
The table can be tilted 0° to 45° to the left and right.
1. Loosen the bevel lock bolt (3) with a wrench.
2. Tilt the table (2) to the desired angle, using the bevel
scale (5) as a basic guide.
3. Re-tighten the bevel lock bolt (3).
4. To return the table to its original position, loosen the bevel
lock bolt. Realign the bevel scale (5) to the 0° setting.
5. Tighten the bevel lock bolt (3) with the wrench.
Setting Drill Depth (FIG 9)
Drill depth scale (4) is on the left side of the drill press
head. See fIG 9. The scale pointer (1) indicates the spindle
travel distance.
To stop the drill at a specific depth for consistent and
repetitive drilling:
1. feed the spindle down to the desired position.
2. While holding it, turn the lower stop nut (2) on the depth
guide (5) all the way down to the stop shoulder (6), then
turn the upper nut (3) down to lock the lower stop nut
on the shoulder (6).
3. The chuck will stop after traveling downward to the
distance selected.
