that the main screw turns clockwise and that the motor pump (if required on machine

model) pumps the coolant liquid. Should not this happen so, invert the current inlet

phases.

ATTENTION: Auxiliary circuit under tension once the main power switch of

machine has been deactivated

Attention: In this machine, when the main power switch is placed at “0” position, the

minimum tension auxiliary circuit remains under tension.

For minimum tension auxiliary circuit maintenance o reparation jobs, put first at “0”

position the protection differential switch to witch the machine has been connected. In

this way, the whole machine electric circuits will remain without electric tension.

In some machine models, the operator must open the machine head cover for changing

spindle speeds. In that case, press the emergency pushbutton first and then, only the

minimum tension auxiliary circuit will remain under tension. The circuit under tension is

identified by the orange color wiring or otherwise, corresponding warning tables will be

stuck to the associated wiring. The rest of the electric circuit will remain without electric

tension.

Please, check thoroughly the electric drawing of the supplied machine in the instruction

book for any maintenance or reparation job.

Note: The machine must be connected to the electric power through a protection

differential switch. Any electrical maintenance or reparation job must be made for

qualified and trained technician.

SECURITY AND GENERAL INFORMATION.

1. SECURITY.

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 a 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

reaches the tapping depth previously fixed.

3. CORRECT USE OF THE MACHINE.

The correct use of the machine involves:

 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 safety measures mentioned in the instruction book and notices on the

machine.

 Wearing clothes which provide personal protection as mentioned in the instruction

book.

 Watching the safety 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 one of the operations mentioned above) must be clamped in an

appropriate device such as a drillchuck and the drillchuck 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 tapershanks.

Drillholders are normally used to fix to the main spindle of the machine the parallel shank

tools. This fixing device has usually got three jaws, which hold the tool by the parallel

part of the shank. These are used for small drill diameters (max. up to dia. 16mm).

Bigger diameter drills, usually have taper shank of morse taper type (the ones of smaller

diameters to 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
