The Bevel Scale (C), on the table mounting, is graduated in degrees to assist in

setting the angle. For normal operations the table should be set at 0°.

(See Figure 3)

To ensure the drill is precisely perpendicular to the table, insert a piece of straight

round bar in the chuck, place a square on the table and bring it up to the round bar.

Adjust the table tilt if necessary so that the table is correctly aligned.

Located on the left side of the drill head (G) is the Spindle Feed (or depth feed)

adjuster assembly, which allows the depth of the hole to be

set. The procedure for setting the drilling depth is as

follows (See Figure 4):

Lower the Chuck (F) until the drill contacts the surface

of the workpiece and hold that in position.

Screw down the adjuster nut (B) so that the gap

between its underside and face (E) is the depth of the

hole required.

Screw down nut (C) and lock it against the adjuster nut

(B).

The drill is now set to drill holes to your predetermined depth from that particular

start point (i.e., providing the surface of your workplace is flat and level, you may drill a

series of holes, each to the same depth.

The scale (H) and pointer (D) can be used to drill one off, by lowering the chuck —

as explained above in "To Set Drilling Depth" section — until the drill contacts the work,

setting the pointer (D) against a set point on the scale (H), switching the drill ON and

proceeding to drill to the required depth using the scale (H) as a guide.

Switch machine OFF and unplug it.

Open the pulley cover.

Loosen the Belt Tension Locking Screw to relieve tension on the drive belt.

Consult the chart inside the pulley cover (or

pulleys according to the spindle/drill speed required

When the belts have been correctly positioned, tighten them by levering the motor

away from the head until the belt deflects by approximately 1/2" at its center when
