SEttIng thE REQuIRED angLE
The Bevel Scale (C), on the table mounting, is graduated in degrees to assist in 1.
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.
tO SEt DRILLIng DEPth
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 1.
of the workpiece and hold that in position.
Screw down the adjuster nut (B) so that the gap
2.
between its underside and face (E) is the depth of the
hole required.
Screw down nut (C) and lock it against the adjuster nut
3.
(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.
