Table Tilt Adjustment

The table tilt adjustments are made on the table
bracket under the table.
To tilt the table (refer to Figures 14 and 15):
In the following steps do not over loosen. This
could result in the table assembly to separate
from the column, fall and cause injury.
1. Loosen the socket head set screw (A) with a
3mm hex wrench.
2. Using a 15/16" wrench, loosen the hex cap
screw (B), and tilt the table to the desired angle
by aligning the arrow (C, Fig. 15) on the rotating
part of the bracket to the desired angle (in
degrees) displayed on the scale (D, Fig 15) at
the base of the bracket.
3. Tighten the hex cap screw (B).
4. Tighten the socket head set screw (A).

Operation

Installing Drills

Insert the drill into the chuck jaws about 1" (25.4mm)
long. When using a small drill do not insert it so far
that the jaws touch the flutes of the drill. Make sure
that the drill is centered in the chuck before
tightening the chuck with the key.

Positioning the 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 should contact the left
side of the column.

Using the Vise

For the small workpiece that cannot be clamped to
the table, use a drill press vise. The vise must be
clamped or bolted to the table. Always use a back-
up piece of scrap wood to cover the table. This
protects both the table and the drill bit.

Basic Operation

Place material to be drilled in such as way as to
come into contact with the left side of the column.
This prevents the material from spinning.
If the work piece is not large enough to come
into contact with the column, use a clamp or drill
press vise that is securely fastened to the table!
Failure to comply may cause serious injury!
Feed the bit into the material with only enough force to
allow the drill bit to work. Feeding too slowly may cause
burning of the workpiece. Feeding too quickly may
cause the motor to stop and/or the drill bit to break.
Generally speaking, the smaller the drill bit, the greater
the RPM required. Wood requires higher speeds than
metal. Metal is usually drilled at slower speeds.
In dusty environments, frequently blow out any dust
that accumulates inside the motor.

Maintenance

Before any intervention
disconnect it from the electrical supply by
pulling out the plug or switching off the main
switch! Failure to comply may cause serious
injury.
A coat of automobile-type wax applied to the table
and column will help to keep the surfaces clean.
If the power cord is worn, cut, or damaged in any
way, have it replaced immediately.

Lubrication

All of the ball bearings are packed with grease at the
factory. They require no further lubrication.
Periodically lubricate the gear, rack, table elevation
mechanism, the splines (grooves) in the spindle, and
the teeth of the quill with a #2 tube grease.
