referring to the chart inside the belt cover (which is
duplicated on page 12), fit the belt in the position
corresponding to the spindle speed required.
CHECKING THE OPERATION OF THE MICROSWITCH
When closing the cover, check the operation of the Microswitch. It is important that it
operates immediately the cover is pulled open, in order to prevent the machine from
operating........NOT when the cover is opened sufficiently for fingers to be inserted.
If necessary, bend the actuating tab, which is attached to the cover, to ensure this.
IMPORTANT:
2.Lever the motor, on its bracket, away from
the head, so that tension is applied to the
belt.Tension is correct, when the belt
deflects by approx. ½” at its centre, when
using reasonable thumb pressure. Lock the
motor in this position using the Locking
Screw.
NOTE: I
f the belt should slip whilst drilling, adjust
the belt tension.

SETTINGS and ADJUSTMENTS
1. Table.
The table may be raised, lowered or swivelled about the
column, by slackening off the table support locking handle,
(Fig. 7), adjusting accordingly, and re-tightening the handle.
Fig. 8
It may also be tilted by loosening the screw, which
secures the table to its’ mount, beneath the table, tilting
to the required position, and re-tightening the screw.
A bevel scale is provided on
the table mounting,
measured in degrees, to
assist in setting the required
angle.
For all normal operations,
the table should be set to 0°.
Table shown tilted and swivelled
about the column
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.

Table Tilt Scale
2. Spindle Depth
Located around the Spindle Feed Shaft is a Depth Stop Collar carrying a graduated scale
(A, Fig.10). The Collar is capable of turning about the shaft and may be locked in place by
Locking Screw B. The Graduations are Imperial (inches) and
Metric (mm).
To set a driling depth:
Lower the drill bit...WITH THE POWER OFF, so that it contacts
the work, and hold in that position with one hand whist
slackening the locking screw (B) and rotating the scale so
that the measurement for the depth of hole to be drilled is in
line with the pointer (C). Lock the collar in this position with
the locking screw (B).
The drill is now preset to drill holes to your pre-determined
depth. i.e. Providing your workpiece is level and flat, you
may drill a series of holes, each to the same depth, quickly
and accurately.

3. Changing Drill (Spindle) Speed.
Before changing the speeds, ensure the
machine is switched OFF and disconnected
from the mains supply.
1.Slacken off the Belt Tension Locking
Screw (see fig.5), to relieve any tension
on the drive belt.
2.Open the pulley cover.
3.Consult the chart inside the pulley
cover and position the belt on the
pulley’s according to the spindle
speed required.
4.When the belt has been correctly positioned, re-tension by levering the motor away
from the head, until the belt deflects by approx. ½” at its centre when using
reasonable thumb pressure. Lock the motor in this position with the Belt Tension Locking
Screw. Finally, recheck the operation of the Microswitch (see page 10)
Fig. 11
DRILL SPEED TABLE
The table below gives the belt arrangement for given drill speeds. The diagram shows the

OPERATION.
1 . Insert the drill bit into the jaws of the chuck by approx 1", ensuring that the jaws do not
touch the flutes of the drill. Before tightening the chuck, ensure that the drill is centred
within the jaws.
2.Ensure the table height and position is set so that drill travel is sufficient for the job in
hand.
3.Ensure the work is securely clamped or held in a drill vice, bolted to the table. Never
hold it with bare hands. Severe personal injury may be caused if the workpiece is
whipped out of the operator’s hand and damage to the machine incurred if the work
strikes the column.
If the piece is of irregular shape and cannot be laid flat on the table, it should be
securely blocked and clamped.
Any tilting, twisting or shifting, results not only in a
rough hole but also increases drill breakage.
4.For small workpieces, that cannot be clamped to
the table, use a Drill Press Vice. The vice must be
clamped or bolted to the table.
5.When drilling completely through wood, always
position a piece of scrap wood between the
workpiece and the table to prevent splintering on
the underside of the workpiece as the drill breaks
through. The scrap piece of wood must make
contact with the left side of the column as shown in
Fig 12. In addition, set the depth of drill travel so
that the drill cannot possibly come into contact
with the table, or align the table so that the hole in
its’ centre is directly in line with the drill bit.
Fig. 12
6.When completely satisfied that the setup is sound, lower the Chuck Guard into
place, and switch the machine ON by pushing the GREEN ‘I’ button. To switch
OFF...push the RED ‘O’ button, see fig. 13.
Fig. 13
NOTE:
a. As a safety feature, the ON/OFF switch is a No Volt
Release type. Therefore, if the power is interrupted
whilst the machine is switched ON, it will not
automatically start when the power is restored.
b. A Micro switch is provided within the Pulley Cover,
which prevents the machine from operating unless
the Pulley Cover is firmly closed.
Drill Press Vices, Cross Vices and Clamps,
are available from your CLARKE dealer.

MAINTENANCE
For maximum performance, it is essential that the Drill Press is properly maintained. Always
inspect before use. Any damage should be repaired, and faults rectified.
If the mains lead is worn or cut, or damaged in any way, it should be replaced immediately.
Please refer to the trouble shooting chart on page 13 . If you are unable to rectify any faults,
please contact your local dealer or Clarke International Service Division on 020 8556 4443
for assistance.
Monthly (When in constant use)
1.Check tightness of mounting bolts, and, head and column securing set screws.
2.Check belt for wear, and replace if frayed or damaged in any way.
3.Blow out any dust that may have accumulated in the motor fan.
4.Apply a thin coat of wax paste or light oil to the table and column, for lubrication, and
to help prevent corrosion.
Lubrication
All bearings are packed with grease at the factory and require no further lubrication.
After use
Remove all swarf from the machine and thoroughly clean all surfaces.
Components should be dry, with machined surfaces lightly oiled.
Always remove drill bits, and store in a safe place.
CUTTING SPEEDS
Factors which determine the best speed to use in any drill press operation are:
• Kind of material being worked • Size of hole • Quality of cut desired • Type of Drill
Generally, the smaller the drill, the greater the required RPM. In soft material, the speed
should be higher than for hard metals.
As a general guide, the drill speed for a given drill bit size, is according to the table below.
