For maximum performance, it is essential that the Drill Press is properly maintained. Always
inspect before use. Any damage should be repaired, and maladjustments rectified.
Please refer to the trouble shooting chart on page 14 . 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.
If the mains lead is worn or cut, or damaged in any way, it should be replaced immediately.
Lubrication
All bearings are packed with grease at the factory and require no further lubrication.
Lubricate the Quill Shaft assembly with light oil, weekly.
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 guide, the drill speed for a given drill bit size, is according to the table below.
3. Screw the three feed handles, firmly into the hub of
the feed shaft. (Fig. 3)

OPERATION.
1 . Insert the drill 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 theunderside 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 9 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 in line with the
drill bit.
6. When completely satisfied that the setup is sound, lower the Chuck Guard into place,
and switch the machine ON by pushing the ‘I’ button. To switch OFF...push the ‘O’
button, see fig. 10.
NOTE:
1. 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.
2. A Micro switch is provided within the Pulley
Cover, which prevents the machine from
operating unless the Pulley Cover is firmly
closed.
A complete range of Drill Press vices, Cross Vices
and Clamps, is available from your Clarke dealer
Fig. 9.
Fig. 10.
D. Chuck Guard Assembly
Slide the Chuck Guard over the Quill Shaft and nip up the pinch bolt at the rear of the
assembly. Ensure the Quill Shaft/Spindle is at the top of its travel.
NOTE: This operation should be carried out before the chuck is installed.
E. Installing the Chuck.
1. With the chuck guard lifted clear of the
spindle nose and turned so that the pinch bolt
is facing the front, as shown in Fig.4, slide the
work table up the column to within 6" of the
spindle.
2. Open the jaws of the chuck to their
maximum, using the chuck key supplied.
3. Put a piece of scrap wood on to the table to
protect the chuck nose, see illustr. opposite.
4. Ensuring all parts are thoroughly clean, dry,
and burr free, place the chuck over the end
of the spindle, and pull the spindle down
using the feed handles, pressing the chuck
jaws hard against the piece of scrap wood
until the chuck is forced home. (See Fig.4)
5. When the chuck is installed, turn the chuck
guard around so that the shield is facing the
front, and tighten the pinch bolt to secure it in
position.
Fig. 4
Fig. 5
F. Tensioning the Drive Belt.
The drive belt is pre-installed, but should it require
tensioning or spindle speed to be changed,
proceed as follows:
1. Undo the Belt Tension Locking Knob to
relieve any tension on the belt, and referring
to the chart inside the belt cover (which is
duplicated on page 11), install the belt in the
position corresponding to the spindle speed
required.
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 Knob.
NOTE: If the belt should slip whilst drilling,adjust
the belt tension.
IMPORTANT. When closing the cover, check the
operation of the microswitch. It should operate
IMMEDIATELY the cover is opened. Undo the
microswitch fixing screws and adjust accordingly.

G.Assembling the Spindle Depth Stop Assy.
Fig. 7
Slide the end of the threaded rod through the
bracket on the side of the head and through the
hole in the top of the Chuck Guard. Secure with
the nut provided, from beneath, thereby locking
the Depth Stop to the Chuck Guard and hence
the Spindle.
(Therefore, as the Spindle is moved downwards,
the depth Stop will move by the same amount).
The pointer may be zeroed by sliding it up or down
on its mounting.
For adjustments, see below.

SETTINGS and ADJUSTMENTS
1. Table.
The table may be raised, lowered or swivelled about
the column, by slackening off the table support
locking handle, adjusting accordingly, and retightening the handle. It may also be tilted by
loosening the Set Screw beneath the table, tilting to
the required position, and re-tightening the Set
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°.
To check to ensure the drill is entirely 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 perfectly square.
2. Spindle Depth Stop Assy (Ref Fig. 7)
To set a required depth of hole, adjust the Depth Stop as Follows:
1. Lower the Chuck with the power OFF, until the drill contacts the surface of the
workpiece, and hold in that position.
2. Spin down the adjuster nut so that the gap between its’ underside, and face of the
bracket (A fig 7) is the depth of the hole required, (shown at ‘B’). Spin down the lock nut
and lock it against the adjuster nut.
Fig. 8
The drill is now set to drill holes to your predetermined depth, from that particular start point.
i.e. Providing the surface of your workpiece is flat and level, you may drill a series of holes,
each to the same depth.
The scale and pointer can be used to drill one off, by lowering the chuck as described
above, until the drill contacts the work, setting the pointer against a set point on the scale,
switching ON the drill, and proceeding to drill to the required depth, using the scale.
3. Changing Drill (Spindle) Speed.
Before changing the speeds, ensure the machine is switched OFF, and disconnected from
the mains supply.
1. Open the pulley cover.
2. Slacken off the Belt Tension Locking Knob, to relieve any tension on the drive belt.
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 Knob.
