• Pull the motor towards the rear,until the belt has the
right tension.
Note:The belt tension is correct,if you can depress the
belt between the pulleys approximately 12mm.
• Retighten the belt tension knobs (1) on both sides of
the drill head.
TILTING THE DRILL HEAD
Fig.Q
To enable drilling at an angle other than perpendicular,
the drill head can be tilted max.45˚ clockwise and 90˚
anticlockwise from vertical.
• Loosen the tilt locking clamp (1) on the right-hand
side of the column head bracket.
• Pull and turn the vertical locking button (2) on the
left-hand side of the column head bracket.
• Align the mill-cut V-groove (4) on the protractor (3)
on the column head bracket to set the exact angle
desired.
• Fix the drill in this position by tightening the tilt
locking clamp (1).
•To return to the perpendicular position,loosen the
tilt locking clamp,and turn the vertical locking
button (2) such that it can click back into the groove
in the horizontal tube.
• Once the perpendicular position is reached,the
button will click back into the mill-cut groove (5) in
the horizontal tube.
• Retighten the tilt locking clamp,to fix the drill head in
this position.
SHIFTING THE DRILL HEAD FORWARDS
AND BACKWARDS
Fig.R
The drill head can be moved horizontally forwards and
backwards a maximum of 320 mm.This enables a
workpiece with a maximum width of 806 mm to be
drilled,or the drill can be shifted between holes,without
continually having to move and re-clamp the workpiece.
• Loosen the tilt locking clamp (1).
•Turn the horizontal drill button (2) to set the drill
head in the correct position.
• Before drilling,retighten the tilt locking clamp (1),to
prevent the bit from slipping away on the workpiece.
PLUMBING THE SPINDLE ABOVE THE TABLE
Fig.S
Before setting up the drill press,always remove the
plug from the mains power socket,to avoid
possible injury.
The radial arm drill press has been set up in the factory,
so that the axis of the spindle housing is perpendicular to
the table.
Normally,further adjustment is not necessary.However,
in transit and assembly,it is possible that the spindle
housing can become misaligned.Check this,and adjust if
necessary,as follows:
• Check the calibration of your combi-square (see
Fig.T).
•Verify that the vertical locking button (1) is correctly
seated in the mill-cut groove (2) of the horizontal
tube.
• In the chuck,insert a either a 76 mm long round steel
precision rod,or a long drill bit,and place a combi-
square on the table.Check that the rod or bit and the
table are aligned.
• If the angle is not perpendicular,loosen both
adjusting screws (4) that fix the spindle housing (5)
to the horizontal tube.These screws are on both
sides of the spindle housing.Tilt the spindle housing
until the rod is perpendicular to the table.Retighten
the adjusting screws.
•Following this adjustment,recheck the drive belt
tension,and adjust,if necessary.
CALIBRATION OF THE COMBI-SQUARE
Fig.T
• On a broad plank,draw a fine line perpendicular to
the length,using the square.
•Now flip the combi-square on the plank and hold it
tightly against the plank at the position of the drawn
line.
• Inspect closely the edge of the combi-square against
the drawn line.The ruler edge should be perfectly
aligned on the drawn line,and there should be no
split or cross-over with the line.
WORKING WITH THE RADIAL
TABLE DRILL
YOUR SAFETY
For your own safety,always observe the safety
guidelines.You will find these guidelines near the
beginning of this operator's guide.
Wear no loose clothing,ties or jewellery,to avoid
the risk of being pulled into the machine.Always
tie-back long hair.
• If any part of your drill is missing,working poorly,
damaged or defective,then stop work immediately,
until that part has been correctly repaired or
replaced.
•Never place your fingers in such a way that they
could come into contact with the bit or other cutting
tool.The workpiece could unexpectedly shift,or
your hand could slip into harm’s way.
•Follow carefully the directions for adjusting the
return spring tension of the spindle,to avoid injury
that could be caused by parts flying out rapidly from
the spring.
•Always take care that the workpiece is well clamped,
to avoid a workpiece being pulled from your hand or
flying off the drill,being spun on the tool or
splintering.Therefore,always work as follows:
a) Always place a block of wood under the
workpiece.The block of wood should be laid against
the left-hand side of the column.You can also make
use of the dog provided,to hold a smaller piece tightly.
b) Whenever possible,place the workpiece against
the left-hand side of the column.If the workpiece is
too short,or if the table is tilted,clamp the workpiece
immovably on the table,or use the dog provided.Use
the slots in the table for this.
c) If you make use of a vice,always bolt this to the
table.
d) Never work with free hands (holding the
workpiece in the hand,instead of fixing to the table),
except for polishing.
e) Ensure the drill head and the table support are
firmly clamped to the column,and the table to the
table support,before commencing drilling.
f) Never move the drill head,the table or the swivel
arm,while the tool is running.
g) Before commencing work,switch the machine
on momentarily,to check that the tool does not
wobble or cause vibrations.
h) If the workpiece extends so far from the table
that it would fall or tilt when released,then it must be
clamped firmly to the table or supported to prevent
this.
i) For unusual work,use the dog provided,or other
clamping arrangements,so that the workpiece can
be adequately held,guided and positioned.
j) Observe the recommended spindle speeds for
the planned work and material involved.Check
carefully the information on the inside of the drive
belt guard,or the drilling speeds given in the table
below.Follow carefully the directions for use of the
accessories.
•Never climb on the drilling table.This can break,but
also the entire drill press can come down on you.
• If you leave the drill press,switch the motor OFF and
remove the switch key.
•Prevent injury.Do not perform any preparatory,
assembly,or construction work on the table,while
the cutting tool is running.
SPEEDS AND BELT FITTING
Fig.U
Spindle speeds
Your radial arm drill press has a motor with 1400 RPM
and five spindle speeds,which are transmitted,via a belt
and pulley drive system.The various spindle rotational
speeds are used for different materials,different bit
types and sizes,and different cutting tools.
The various configurations for fitting the belt to the
pulleys for the five available spindle speeds are described
on this page,and inside the drive belt guard.The highest
speed is accomplished by fitting the belt to the largest
pulley of the pulley block at the motor end,and at the
same time to the smallest pulley of the pulley block at the
spindle end.

Prevent injury.Keep the drive belt guard closed,
correctly fitted and functioning properly,when
working with the machine.
CHANGING SPEEDS
Fig.V
Switch the machine OFF and remove the plug from
the power socket,before you change the speed.
• Open the drive belt guard (1).
• Place the belt (2) on the desired pulley of the spindle
pulley block,and that of the motor pulley block.
Note:When changing speeds,always begin at the end
with the larger pulley engaged to the belt.
ON/OFF SWITCH
•Press the switch upwards to the ON position,to
start the drill press.
•Press the switch downwards to the OFF position,to
stop the drill press.
INSERTING THE BIT IN THE CHUCK
Fig.W
• The switch is OFF.Open the jaws of the chuck (1)
using the chuck key (2).To open the jaws,turn the
chuck key anticlockwise.
• Insert the bit (3) far enough into the chuck for an
optimal grip in the jaws,but not so far that the jaws,
when closed,cover the spirals of the bit.
• Check carefully that the bit is centred in the chuck.
•Turn the chuck key clockwise,to close the jaws.
Use exclusively the chuck key provided,with
automatic ejection,to avoid injury or accident from
a chuck key thrown off at high speed by when the machine is
switched on. Always check and remove the chuck key before
switching the machine on.
To prevent the workpiece or the wooden filler block
beneath it from being wrenched out of your hands
during drilling,you should lay the workpiece against the left-
hand side of the column.If the workpiece or the filler block is
too short to reach the column,clamp the workpiece
immovably on the table,or use the dog provided.A workpiece
that is not properly clamped can cause serious injury.
