handle (Fig.2).
3. Fit the table crank to the drive spigot.
4. Screw the arm locking handle into place
on the rear of the column support.
DRILL PRESS HEAD TO COLUMN
CAUTION: THE HEAD ASSEMBLY IS HEAVY. TO AVOID ACCIDENT, TWO
PEOPLE SHOULD LIFT IT INTO POSITION.
1. Carefully lift the head assembly and
position it with its mounting opening over
the column. Swivel the assembly to
ensure it is seated correctly on the
column.
NOTE: It may be necessary to unscrew the
head locking set screws (A in Fig 2)
slightly to ensure they do not protrude
internally so as to prevent the head from
sliding fully into position.
2. Align the drill press head with the
direction of the base.
3. Tighten the set screws using an allen key.
Fig 2
Fig 3
FEED HANDLES
1. Screw the three feed handles into the threaded holes in the feed hub and
tighten by hand.
NOTE: When using the drill, one or two of the feed
handles may be removed if an unusuallyshaped workpiece interferes with handle
rotation.
CHUCK GUARD ASSEMBLY
NOTE: This operation should be carried out before
the chuck is installed if the guard cannot be
passed over the chuck.
Slide the Chuck Guard over the Quill Shaft, turn it so
that the pinch bolt faces the front, then nip up the
pinch bolt to temporarily secure it in this position.
IMPORTANT: Ensure the Quill Shaft/Spindle is at the
top of it’s travel.

PULLEY COVER KNOB
Locate the knob, with pan head screw and attach to the cover, screwing on
tightly.
FITTING THE DRIVE BELTS
1. Undo the Belt Tension
locking screws (one
Fig 5
either side of the head
- A Fig. 5), and turn the
Belt Tension Lever (B Fig. 5), clockwise to
bring the Motor Pulley
closer to the Spindle
Pulley which will allow
the belts to be slipped
on with ease.
2. Lightly grease the Idler
Pulley Pivot shaft and
locate the Idler pulley
assembly in it’s mounting between the motor and spindle pulleys.
3. Consult the chart inside the belt cover (duplicated on page 19), and fit
the belts in the position corresponding to spindle/drill speed required.
4. Turn the Belt Tension Lever ant-clockwise so that tension is applied to the
belts. Tension is correct when the belts deflect by approx. ½” at the centre
of their span when using reasonable thumb pressure. Lock the motor in this
position with the Locking Screw - A.
NOTE:
1. The idler pulley will ‘float’ so that tension is applied equally to both belts
If the belt should slip whilst drilling, adjust the belt tension.

Page 13
INSTALLING THE CHUCK
WARNING: DISCONNECT THE DRILL PRESS FROM THE POWER SOURCE
BEFORE INSTALLING, ADJUSTING, OR REMOVING THE CHUCK.
1. Slide the table up the column and
secure it to within 6" of the spindle.
2. Put a piece of scrap wood on to the
table to protect the chuck nose.
3. Ensuring all parts are thoroughly clean,
dry, and burr free, place the chuck over
the end of the arbour 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. (Fig 6).
4. Turn Chuck Guard through 180° and
tighten the pinch bolt.
CAUTION: TO AVOID DAMAGING THE CHUCK, MAKE SURE THE JAWS
ARE COMPLETELY RECESSED INTO THE CHUCK. DO NOT USE A METAL
HAMMER TO DRIVE THE CHUCK INTO THE SPINDLE.
REMOVING THE CHUCK
To remove the chuck, pull the spindle down fully, using the feed handles. The
slot in the side of the Quill will become visible, as shown in fig 7. Note the
position of the chuck, perhaps by placing a chalk mark, in line with the
chuck, on the column, then raise the table so that it is only an inch or so
below the position marked.
Place a thick cloth, or similar, on the table to
catch the chuck, to prevent damage when it
drops, then pull down the spindle once more,
until the slot in the Quill tube is visible. Insert
the drive wedge into the slot and give it a
sharp tap, preferably with a copper hammer.
This will break the seal between the quill tube
and the arbour, allowing the chuck to fall
free, on to the cloth on the table.
Fig 6
Fig 7
13
Page 14
To disconnect the chuck from the arbour, give it a sharp tap with a soft head
mallet to break the taper seal.
NOTE: Morse taper drills (MT2), may also be used with this machine, and are
inserted into the quill to replace the arbour. Removal is the same as that for
removing the chuck.
ASSEMBLING THE ON/OFF SWITCH
Ensure the ON/OFF switch ‘Emergency OFF’
component is attached, as shown, using the two
screws supplied. Make sure the plastic cover is
properly in place before running the machine.
To turn the machine ON, lift the cover guard to
access the ON/OFF buttons. Press the green
push-button to start the machine.
• As a safety feature, the ON button cannot
be pressed without raising the guard.
To turn OFF, press either the OFF button if holding
the guard raised, or press the guard cover at any time.

SETTINGS AND ADJUSTMENTS
TABLE
The table may be raised, lowered or swivelled
about the column, by slackening off the table
support locking handle, (Fig 10), adjusting
accordingly using the table crank, and retightening the locking handle.
If the table assembly moves stiffly when being
swivelled about the column, slacken the upper
collar grub screw (at the rack) to allow the collar
to move very slightly, thereby providing a little
more clearance between rack and collar. Tighten
the grub screw when satisfied.
The table may also be
Fig 10
Fig 11
To check to ensure the table is entirely square to the drill, insert a piece of
straight round bar in thechuck, place a square on the table and bring it up to
the round bar. Adjust the table tilt, if necessary, so the table is correctly
aligned.
turned on its axis by
slackening the pinch bolt
at its mounting
spigot,(Fig 2). Note that
the table will only turn
through an arc and will
eventually come into
contact with the
column. Take care not to
cause damage to the
column.
Tilt the table by loosening the Table Tilt Locking
Screw beneath the table, (Item 7, page 26), tilting
to the required position, & re-tightening the
screw.
A bevel scale is provided on the table mounting,
measured in degrees, to assist in setting the
required angle, (Fig 11). For all normal operations, the table should be set to 0°.
Fig 9
SPINDLE DEPTH
Located around the spindle feed shaft is a Depth Stop Collar, carrying a
graduated scale (A). The collar is capable of turning about the shaft, and
may be locked in place by a Locking Screw (B). The graduations are imperial
15
Page 16
(inches) and metric (mm). To set a drilling depth:
1. With the power OFF, lower the drill bit so that it
contacts the work and hold in that position.
2. Slacken off the locking screw and turn the collar
so that the measurement for the depth of hole
required is in line with the pointer (C). Lock the
collar in this position using the locking screw.
The drill is now set to drill holes to your pre-determined depth, from that particular start point.
Fig 12
CHANGING DRILL (SPINDLE) SPEED
Before changing the speeds, ensure the machine is switched OFF, and
disconnected from the mains supply.
1 Undo the Belt Tension Locking Screws (A -Fig. 13), one either side of the
head, and turn lever B - Fig.13 clockwise to relieve any tension on the
belts. Referring to the chart inside the belt cover (which is duplicated on
page19), install the belts in the positions corresponding to the spindle
speed required.
2. Lever the motor, on its bracket,
away from the head, using the
lever B - Fig.13, so that tension
is applied to the belts.
NOTE: The idler pulley will ‘float’ so
that tension is equally applied to
both belts
Tension is correct, when the belts
deflect by approx. ½” at their
centre when using reasonable
pressure with the thumb and
forefinger.
Lock the motor in this position using the two Locking Screws (A - Fig. 13).
NOTE: If the belt should slip whilst drilling, adjust the belt tension.
Fig 13

Page 17
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.
WARNING: TO AVOID INJURY, MAKE SURE THAT THE CHUCK KEY IS
REMOVED FROM THE CHUCK BEFORE STARTING ANY DRILLING
OPERATION.
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 14. 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 it’s
centre is directly in line with the drill bit.
6. Mark where you want to drill on the
workpiece by using a centre punch.
7. When completely satisfied that the setup is
sound, lower the Chuck Guard into place
and switch the machine ON by raising the
switch cover, as shown in FIG 8, and pushing the GREEN ‘I’ button.
8. Before turning on the drill, turn the feed handles to bring the drill bit down.
Line the drill bit tip up with the mark.
9. Turn on the drill and pull down on the feed handles with appropriate force
needed to allow the drill bit to drill into the material
Fig 14
17
Page 18
10. To switch OFF, hit the switch cover, which will push the RED ‘O’ button,
turning the machine OFF.
Caution: FEEDING TOO RAPIDLY might stop the motor, cause the belt to
slip, force the workpiece loose, or break the drill bit. Practice with
scrap material to get the feel of the machine before attempting
any drilling operation.
NOTES:
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 microswitch is provided within the pulley cover, which prevents the
machine from operating unless the pulley cover is firmly closed.
c. A light is also provided which is built into the head. The lightswitch is
located on the front panel, directly below the ON/OFF switch.
TO ADJUST DRILLING DEPTH
SPINDLE DEPTH SCALE METHOD
1. With the power OFF, lower the drill bit so that it contacts the work and hold
in that position.
2. Slacken off the locking screw and turn the collar so that the measurement
for the depth of hole required is in line with the pointer. Lock the collar in
this position using the locking screw.
The drill is now set to drill holes to your pre-determined depth, from that
particular start point.

WORKPIECE METHOD
1. Mark the desired depth of the drill hole on the side of the workpiece.
2. With the machine not running, bring the drill bit down until the tip is level
with the mark.
3. Holding the feed handles at this position and lock the collar in position
using the locking screw. The chuck and the drill bit will now be stopped at
18
Page 19
the distance selected on the depth stop collar.
TO DRILL DIFFERENT MATERIALS
FEEDING THE DRILL BIT
• Pull down on the feed handles with only enough force to allow the
drill bit to cut.
• FEEDING TOO RAPIDLY could stall the motor, cause the belt to slip,
damage the workpiece, or break the drill bit.
• FEEDING TOO SLOWLY could cause the drill bit to heat up and burn
the workpiece.
DRILLING METAL
• Use metal-piercing twist drill bits.
• It is always necessary to lubricate the tip of the drill with oil to
prevent overheating the drill bit.
• All metal workpieces should be clamped down securely. Any tilting,
twisting, or shifting causes a rough drill hole, and increases the
potential of drill bit breakage.
• Never hold a metal workpiece with your bare hands. The cutting
edge of the drill bit may seize the workpiece and throw it, causing
injury. The drill bit will break if the metal piece hits the column.
• If the metal is flat, clamp a piece of wood under it to prevent
turning. If it cannot be laid flat on the table, then it should be
blocked and clamped.
DRILLING WOOD
• Brad point bits are preferred. Metal piercing twist bits may be used
on wood.
• Do not use auger bits which turn so rapidly that they can lift the
workpiece off the table and whirl it around.
• Always protect the drill bit by positioning the table so that the drill bit
will enter the centre hole when drilling through the workpiece.
• To prevent splintering, feed drill bit slowly when the bit is about to
cut through to the reverse side of the workpiece.
• To reduce splintering and protect the point of the bit, use scrap
wood as a backing or a base block under the workpiece.

DRILLING SPEEDS
Important factors when determining the best drilling speed are:
• Material type
• Hole size
• Drill bit or cutter type
• Quality desired
Generally, smaller drill bits require greater speed than large drill bits. Softer
materials require greater speed than harder materials. See the following table
for approximate recommended speeds for the workpiece material.

If the mains lead is damaged it should be replaced immediately.
Please refer to TROUBLESHOOTING on page 23. If you are unable to rectify
any faults, please contact your local dealer or Clarke International Service
Department on 0208 988 7400 for assistance.
AFTER USE
Always remove drill bits, and store in a safe place. The machine requires very
little maintenance other than the following guidelines.
1. Vacuum clean any dust or swarf that accumulates in or on the motor,
drive housing, table and work surface.
2. Lubricate the table bracket and locking handles if they become difficult
to use. Components should be dry, with machined surfaces lightly oiled.
3. Check all cables periodically for security, and that they are in good
condition and not cracked.
IMPORTANT - Disconnect from mains power before cleaning.
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 otherwise damaged.
3. Blow out any dust/swarf 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.
5. Pull the spindle down and lightly oil the spindle sleeve every three months.
• The ball bearings in the spindle are greased and permanently sealed at
the factory and require no further lubrication.
DO NOT attempt to carry out repairs yourself, unless you are fully competent,
all work must be carried out by a qualified technician or the Clarke service
department.
