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 earthing system; connect the power cable of the machine to the socket and theearth
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 white, 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.
- 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 wear loose clothing with sleeves that are too long, gloves that are too big, bracelets, chains or any 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
- Grey metal guards, fastened with screws onto the mobile blade-guide ensures covering of blade section not used in cutting
operation ( A ).
- Grey metal guards, fastened onto the sawframe, to protect from flywheels ( B ).
- Grey metal guard to protect from driving belts ( C ).
- Grey metal fence around the machine, to protect the operator from cutting area ( D ) .

ited by screws that can only be removed with a special tool; the parts are fed with alternating current at low voltage. 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 through the inverter.
- 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.
- In case blade breaks, the pressure switch stops all machine functions.
1.5 - OTHER RISKS
- As the machine is running, any intervention from the operator within the “dangerous zone” or cutting area must be considered a
risk for his own safety.
RECOMMENDATIONS AND ADVICE FOR USE
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.

1.3 - Electrical equipment according to Euro-pean Standard "CENELEC EN 60 204-1" which as-similates,
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 lim
- Before starting each cutting operation, ensure that the part is firmly gripped in the vice and that the end is suitably supported.
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 does not cut through the material, immediately strike the emergency push-button and switch off the machine. Open the
vice with the handwheel, remove part to be cut ad check that the blade teeth are not broken, If they are, replace tool.
- Check saw frame return spring to ensure proper balancing.
- Before carrying out any repairs on the machine, consult the dealer or apply to THOMAS.
