OWNER’S MANUAL
SAFETY AND GENERAL INFORMATION
1. SAFETY
A drilling machine, due to its purpose, is considered an “open
machine” Therefore, some safety measures have to be taken to
avoid accidents.
Bear in mind the following safety instructions:
The machine must always be operated for the purpose for which
was designed.
Do not ever stand under a hanging machine or nearby, when it is
been loaded for transportation.
Connect the machine to an exclusive electric connection, which
includes differential switch of protection. Plug in first the
green-yellow protection wire and then the others.
The piece must always be fastened with suitable devices. Do not
ever handhold the pieces.
Sharpened tools in good condition must always be used.
Appropriate tools must always be used, Do not ever adapt a tool
for a use for which it was not designed.
Use the correct speeds and feeds for the material being machined
as well as for the tool being used.
Use glasses to prevent small chips from getting in the eyes.
Insert the tools correctly in the tool holder cone.
Fix the piece fastening devices to the machine table.
Do not wear baggy clothes, loose gloves, etc, which can be
caught by the tool while drilling.
Keep the working place clean.
Gather the chips with suitable instruments (brush, gloves, etc.)
Before carrying out any operation which is not strictly drilling,
tapping etc. (like lubricating, changing of tools, etc,) turn the

OWNER’S MANUAL
main switch to the “0”position.
Before changing speeds, stop the machine and wait until all
moving elements are completely brought to a halt.
Do not ever leave the machine on without supervision. When
leaving the machine, check that the general switch is in the
“0”position and that moving elements are stopped.
Check periodically the correct operating of all security controls
and elements of the machine.
Before pressing the starting pushbutton, set the drill protector
guard in the working position.
Consider work area environment. Don’t use electric power driven
tools in damp or wet locations. Keep work area well lit. Don’t use
electric power tools in presence of flammable liquids or gases.
Keep children away.
Use only such accessories and attachments as are
recommended in the operating instructions or the catalogue for
the power tool concerned.
2. FORESEEN USE OF THE MACHINE
The drilling machine was designed to be used with specific tools and
for certain machining operations.
The most common machining operation is the drilling of holes with
helicoidal drills. The drilling of hole is carried out by the combination
of a drill turning movement and a feed movement in the turning
spindle direction.
Besides the helicoidal drill, other tools can be used to drill holes.
There is a great variety of drill types and shapes in the market which
can be used on this machine, provided that they are designed for
such a purpose and that can be fixed in the spindle taper. They will
usually be the Morse taper or ISO type. The drill shanks should have
the corresponding taper to the spindle in which they are to be fitted,

OWNER’S MANUAL
or parallel shank if they are going to be fitted by means of a tool
holder. Contact the tool manufacturer for any further information. Do
not ever use tools which were not designed to be used in a drilling
machine and that have been adapted.
A drilling machine can also perform other machining operations a
part from the drilling, such as tapping, reaming, chamfering, punch
marking, countersinking, spot facing, to perform such operations, it
is necessary to have appropriate tools, specially designed for this
sort of jobs. In the tapping case, besides using correct tool, the
machine has to be provided with such a device that verses the turning
direction of the tool when it reaches the depth previously fixed.
3. CORRECT USE OF THE MACHINE
Not exceeding its working capacity.
Operating the machine by qualified and trained staff and
according to the points mentioned in the instruction book.
Working under the safety systems provided with the machine,
checking them and keeping them.
Watching the safely measures mentioned in the instruction book
and notices on the machine.
Wearing clothes which provide personal as mentioned in the
instruction book.
Watching the safely measures which may affect work in the
machine and that can be lawfully expected, as well as those
demanded in the workshops.
4. PIECE CLAMPING.
Tangential cutting forces and axial forces in the feed direction of the
tool are mainly produced during the drilling process. The tangential
forces produce a moment of forces which make the piece being
drilled turn. Therefore, the pieces to be drilled (or to be machined by

OWNER’S MANUAL
one of the operations mentioned above) must be clamped in an
appropriate device such as a drill chuck and the drill chuck must be
correctly clamped to the machine table. For this reason the machine
tables are provided with “T”slots.
The pieces must be clamped conveniently by some clamping device.
The clamping devices in turn must be clamped to the machine table.
The machine table is provided with “T”slots for such purpose.
5. TOOL FIXING
The tools generally used in this machine will have parallel or taper
shanks. Drill holders are normally used to fix to the main spindle of
the machine the parallel shank tools. This fixing device is used for
small drill diameters (max. up to dia.16mm). Bigger diameter drills,
usually have taper shank of Morse taper (the ones of smaller
diameters to 16mm can have taper shanks).
The housing in the main spindle to insert the tool is of Morse taper
type. It is very important to insert the tool taper correctly in the main
spindle taper to avoid the tool falling from its housing when turning
and provoke and accident. The coupling system itself of the tool
male taper in the female taper of the main spindle is auto-locking,
but for it the surfaces of the tool taper and spindle taper must be in
contact. To get the best possible contact, the surfaces of the tool
taper as well as the spindle taper should be in good conditions.
Therefore, it is advisable to handle the tool as well as the spindle of
the machine carefully.
6. CHIPS DURING MACHINE
The machining process removes material from the piece. This
material is released in chips, which can be of different shapes
depending on the material itself. The most common ones are of three
types: fragmented chips in small bits, short helicoidal chips and long

OWNER’S MANUAL
helicoidal chips.
The chips fragmented in small bits can be rejected from the
machining area and can be dangerous if they reach the eyes of the
operator. To avoid this, it is advisable to wear safety glasses.
The long helicoidal chips tend to roll up the tool and gain
considerable volume before breaking, which is dangerous if they
reach the operator as they may produce injuries.
The reached volume may also displace the dill protector from its
security position, increasing the risk of an accident. It is advisable to
use chip breaking tools to machine materials which produce such
chips. For further information contact the tool manufacturer.
