REFERENCE TO A CCIDENT - PREVENTION REGULATIONS
1
This machine has been built to comply with the national and community accident-prevention regulations in force. Improper use
and/or tampering with the safety devices will relieve the manufacturer of all responsibility.
1.1 - Advice for the operator
- Check that the voltage indicated on the plate, normally fixed to the machine motor, is the same as the line voltage.
- Check the efficiency of your electric supply and ear thing system; connect the power cable of the machine to the socket and the
earth lead (yellow-green in colour) to the earthing system.
- When the saw frame is in suspend mode (up) the toothed blade must not move.
- Only the blade section used for cutting must be kept unprotected. Remove guarding by operating on the adjustable head.
- It is forbidden to work on the machine without its shields (these are all blue or grey in colour).
- Always disconnect the machine from the power socket before blade change or carrying out any maintenance job, even in the case
of abnormal machine operation.
- It is forbidden to disconnect the "man present" de vice, kno wn more correctly in the EEC as the " saf ety s witch with hold-do wn action"
- Always wear suitable eye protection.
- Never put your hands or arms into the cutting area while the machine is operating.
- Do not shift the machine while it is cutting.
- Do not use any artful system or device (for ex. shim) to prevent the vice from locking the workpiece. Do not hold the workpiece with
your hand during the cutting process.
- Do not charge the workpiece from the right to the left-hand side with respect of the machine front.
- Do not wear loose clothing with slee v es that are too long, glo v es that are too big, br acelets , chains or an y other object that could get
caught in the machine during operation; tie back long hair.
- Keep the area free of equipment, tools or any other object.
- Perform only one operation at a time and never have several objects in your hands at the same time. Keep your hands as clean as
possible.
- All internal and/or internal operations, maintenance or repairs, must be performed in a well-lit area or where there is sufficient light
from extra sources so as to avoid the risk of even slight accidents.

1.2 - Location of shields against accidental contact with the tool
- Blue, grey right and left hand metal shields, fastened with screws onto the guide blade stationary head ( RIF. A ).
- Blue or grey metal shield fastened with screws onto the blade guide adjustable head, ensures covering of blade section not used in
cutting operation ( RIF. B ).
- Grey metal guard, fastened with knobs onto the saw frame, to protect from flywheels ( RIF. C ).

1.3 - Electrical equipment according to Euro-pean Standard"CENELEC EN 60 204-1" which assimilates,
with some integrating modifications, the publication "IEC 204-1"
- The electrical equipment ensures protection against electric shock as a result of direct or indirect contact. The active parts of this
equipment are housed in a box to which access is limited by screws that can only be removed with a special tool; the parts are fed
with alternating current at low voltage (24 V). The equipment is protected against splashes of water and dust.
- Protection of the system against short circuits is ensured by means of rapid fuses and earthing; in the event of motor overload,
protection is provided by a thermal probe.
- In the event of a power cut, the specific start-up button must be reset.
- The machine has been tested in conformity with point 20 of EN 60204.
1.4 - Emergencies according to European Standard "CENELEC EN 60 204-1"
- In the event of incorrect operation or of danger conditions, the machine may be stopped immediately by pressing the red mushroom
button.
- The casual or voluntary removal of the protection shield of the flywheels causes the stepping-in of a microswitch that automatically
stops all machine functions.
NOTE:Resetting of machine operation after each emergency stop is achieved by reactivating the specific restart button.

RECOMMEND ATIONS AND ADVICE FOR USE
2
2.1 - Recommendations and advice for using the machine
- The machine has been designed to cut metal building materials, with different shapes and profiles, used in workshops, turner’s
shops and general mechanical structural work.
- Only one operator is needed to use the machine, that must stand as shown in the picture.
- Before starting each cutting operation, ensure that the part is firmly gripped in the vice and that the end is suitably suppor ted.
These figures show examples of suitable clamping of different section bars, bearing in mind the cutting capacities of the machine in
order to achieve a good efficiency and blade durability.
- Do not use blades of a different size from those stated in the machine specifications.
- If the blade gets stuck in the cut, release the running button immediately, switch off the machine, open the vice slowly, remove the
part and check that the blade or its teeth are not broken. If they are broken, change the tool.
- Check saw frame return spr ing to ensure proper balancing.
- Before carrying out any repairs on the machine, consult the dealer or apply to THOMAS.

4.5 - Instructions for electrical connection
- The machine is not provided with an electric plug, so the customer must fit a suitable one for his own working conditions:
1 - WIRING DIAGRAM FOR 4-WIRE SYSTEM FOR THREE-
PHASE MACHINE - SOCKET FOR A 16A PLUG
4.7 - Disactivating the machine
- If the sawing machine is to be out of use for a long period, it is
advisable to proceed as follows:
1)detach the plug from the electric supply panel
2)loosen blade
3)release the arch return spring
4)empty the coolant tank
5)carefully clean and grease the machine
6)if necessary, cover the machine.
4.8 - Dismantling
(because of deterioration and/or obsolescence)
General rules
If the machine is to be permanently demolished and/or scrapped,
divide the material to be disposed of according to type and composition, as follows:
1)Cast iron or ferrous materials, composed of
secondary raw materials, so they may be taken to an iron
foundry for re-smelting after having removed the contents
(classified in point 3);
2)electrical components, including the cable and electronic ma-
terial (magnetic cards, etc.), fall within the category of material classified as being assimilable to urban waste according to the laws of the European community, so they may be
set aside for collection by the public waste disposal service;
3) old mineral and synthetic and/or mixed oils, emulsified oils
and greases are special refuse, so they must be collected,
transported and subsequently disposed of by the old oil disposal service.

4.6 - Instructions for assembly of the loose parts
and accessories
Fit the components supplied:
- Mount bar-stop rod
- Mount and align the roll supporting ar m as per the

NOTE:since standards and legislation concerning refuse in gen-
eral is in a state of continuous evolution and therefore
subject to changes and variations, the user must keep
informed of the regulations in force at the time of disposing of the machine tool, as these may differ from those
described above, which are to be considered as a general guide line.

MANUAL MODE WITH DOWNFEED DAMPER
- As you turn the selector ( 4 ) to the left ( see figure A ), you
can pull down the sawframe manually at the feed rate set on
the regulator ( 5 ).
- If you w ant to approach the sawframe to the workpiece quickly
( blade not started ), press the button located on top of the
trigger switch ( 6 - figure D ); as you release the button, the
sawframe stops.
- Press the trigger switch ( 7 - figure D ) to start the blade and
pull down the sawframe manually to cut the workpiece. The
motor will stop automatically as soon as you release the trigger
switch..
