NOTE
This manual has been prepared for the owner and operators of this machine. Its purpose,
aside from machine operation, is to promote safety through the use of accepted correct
operation and maintenance procedures. Completely read the safety and maintenance
instructions before operation or servicing the machine. To obtain maximum life and
efficiency form your machine, and to aid in using the machine safety, read this manual.
Since we continually strive to incorporate latest developments in the construction of the
machine, it is quite possible at time, due to printing and shipping requirements, some data
may not correspond to the machine in question.

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:
FThe machine must always be operated for the purpose for which it was designed.
FDo not ever stand under a hanging machine or nearby, when it is being loaded for
transportation.
FConnect the machine to an exclusive electric connection, which includes differential
switch of protection. First plug in the green-yellow protection wire and then the others.
FThe piece must always be fastened with suitable devices. Do not ever handhold the
workpieces.
FSharpened tools in good condition must always be used.
FAppropriate tools must always be used, Do not ever adapt a tool for a use for which it
was not designed.
FUse the correct speeds and feeds for the material being machined as well as for the
tool being used.
FUse glasses to prevent small chips from getting into the eyes.
FInsert the tools correctly in the tool holder cone.
FFix the work piece fastening devices to the machine table.
FDo not wear baggy clothes, loose gloves, etc, which can be caught by the tool while
drilling.
FKeep the working place clean.
FGather the chips with suitable instruments (brush, gloves, etc.)
Before carrying out any operation which is not strictly drilling,

Ftapping etc. (like lubricating, changing of tools, etc,) turn the main switch to the
“0”position.
FBefore changing speeds, stop the machine and wait until all moving elements are
completely brought to a halt.
FDo 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.
FCheck periodically the correct operating of all security controls and elements of the
machine.
FBefore pressing the starting pushbutton, set the drill protector guard in the working
position.
FConsider 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.
FKeep children away.
FUse 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 holes 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, 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.
A drilling machine can also perform other machining operations apart 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
FNot exceeding its working capacity.
FOperating the machine by qualified and trained staff,and according to the points
mentioned in the instruction book.
FWorking under the safety systems provided with the machine, checking them and
keeping them.
FWatching the safety measures mentioned in the instruction book and notices on the
machine.
FWearing clothes which provide personal safety as mentioned in the instruction book.
FWatching the safety measures which may affect work on 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 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 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 the main spindle of the machine to 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 than 16mm can
also 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 an accident. The coupling system itself of the tool male
taper in the female taper of the main spindle is auto-locking, but for it to work 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 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 drill 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.
