1.- INTRODUCTION.
The current instruction manual has been realised in accordance with the requirements of
the set of standards in compliance with the Machines 89/392/EEC guideline and the
consecutive modifications.
The instruction manual constitutes an integral part of the machine and should be
consulted before, during and after commissioning of the machine as well as every time
you consider it necessary, honouring its contents concerning each and all the
corresponding parts.
This is the exclusive way to obtain the fundamental objectives, which are laid down in the
basis of this manual, such as avoiding accident risks and optimising the performance
of the machine as much as possible.
This manual concentrates thoroughly on various aspects regarding safety and prevention
of accidents at work while operating the machine, thereby emphasising the information
that is of major importance to the user.
ATTENTION: READ THIS MANUAL CAREFULLY BEFORE INSTALLING THE
MACHINE.

4.- INSTRUCTIONS REGARDING TRANSPORT AND STORAGE.
- In order to guarantee a safe movement and transport it is recommended to use a lift
truck for internal transportation or a mobile crane.
Store in vertical position.
Do not stack up.
In case the machine is kept in storage for a long period, it should be greased
periodically.
Do not store machine outdoors.

5.- INSTRUCTIONS FOR INSTALLATION AND COMMISSIONING.
- Installation instructions.
Prior to installation, initially check that no damage was inflicted to the machine during
transportation. In the event of any damage, however, it must be brought to the manufacturer’s
notice immediately.
The machine must be set up on a stable foundation and as much as possible on a horizontally flat
surface in order to reduce the vibrations during operation and functions as per the parameters
adjusted beforehand.
- Connection to the power supply.
Determine if the voltage supply corresponds to
the designation on the motor plate. Connect the
cable to the line by means of a plug adapted to
the characteristics, take into consideration the
colour codes of each of the cables, pay special
attention to the grounding of the cable.
Once the machine has been connected, please
check that the direction of rotation of the saw
blade corresponds to the direction of the arrow
situated on the left-hand side of the machine.
Check that the air pressure is appropriate ( 6 atm. ) for which purpose the pressure gauge of the
machine may be used.
- Instructions concerning the saw blade assembly.
In order to mount the saw blade, the
operating switch should be turned off, access
the inner part of the machine through the front
door, fix it on the shaft of the tipping gear
(nº2), place the washer nº18 and centre it by
means of a rod, press the nut (nº 19) as
indicated on the drawing. Make sure that the
direction of the teeth of the saw coincide with
the direction of rotation of the motor. Bear in
mind that the maximum diameter of the saw
blade is 500 mm.

TL - 500 -AA

- Cooling agent for sawing.
In order to fill the cooling agent for sawing purposes, you should turn off the operating switch
and fill with PURE CUTTING OIL NOT EMULSIFIABLE IN WATER WITH VISCOSITY OF ISO
VG 10-16.
- Oil atomiser for pneumatic components and filter.
The pneumatic oil tank should be filled by means of a lateral screw on the tank and fill it
with PNEUMATIC OIL OF A VISCOSITY OF ISO VG 16 or similar. Use the same oil for the
lubricating device situated in the group of pneumatic components.
6.- OPERATION INSTRUCTIONS.
- Proper and improper use.
Manual cross-cut saw for cutting aluminium, brass, copper, bronze, etc.
It is prohibited to saw other materials with this machine; if this is done regardless, it may
cause damage to the machine and jeopardise the safety and health of the operator.
We cannot be held liable for damages or accidents associated with improper use of the
machine.

Material parts counter with pre-selection.
Reset button to return to the chosen number of cuts.
In order to change the selection it is necessary to keep the
reset button pressed and at the same time press the push button of
the desired digit.
- Operating mode. Sequence of operation.
With the switch of the operation modes in MANUAL POSITION, the pressing cylinders and
the saw blade may be operated by means of the push buttons at the front side of the machine. It is
recommended not to use materials with a too high feeding speed of the saw blade, because this
reduces the longevity of the saw blade and the cutting quality enormously. The machine in
MANUAL POSITION also counts the number of cuts, although it does not stop the saw blade
when reaching the zero digit.
In order to operate the feeder, the following procedures must be complied with:
1. Adjust the desired sawing height by means of the limit switch located in the inner part of the
machine, always with the operating switch turned off.
2. Adjust the feeding length with the guiding wheel of the feeder. The read-out appears on the
counter located in the spindle.
3. Adjust the pressing cylinders of the machine and those of the clamping device of the feeder
to the material, so that a space of no more than 5 mm is realised. It is important that the
microswitch of the present material (placed in the clamping device of the feeder) is
pressed, and that the piece counter does not indicate zero. In contrast, it will
not be possible to either have the saw blade turn or to put the feeder in
operation.
4. Place the rod on the feeder, so that it passes at a distance of approximately 10 mm from
the groove of the saw blade.
5. Assemble the operating switch.
6. Start operating the saw blade.
7. Choose the operating procedure, AUTOMATIC.
8. Start the operating cycle by pressing the start button of the feeder.

TL - 500 -AA

The machine will stop automatically when the material is finished when pressing the stop
button, the emergency stop, the piece counter reaching the number zero, changing to
MANUAL PROCEDURE, or raising the protection hood.
When working with the feeder it is very important to regulate the operating speed in
order to avoid shocks at the end of the operating procedure, and that no sliding of the material will
occur, due to brusque movements. For this it is necessary to get access to the electric valves
through the backdoor of the feeder, and adjust the connecting pieces of the electric valve nº4 . By
setting the nearest connecting piece at the electric connector, the advancing speed of the material
is reduced, and by setting the other one, the reversing speed is reduced.
While the feeder is in operation, always keep the protection hood lowered

- General operating standards and safety checks.
Prior to using the machine, check that all the safety devices function properly and check that
the movable parts of the machine are free to move, that there are no damaged parts and
that all the parts of the machine are properly secured enabling the machine to function
perfectly.
Do not leave the keys of the doors in the machine.
The use of gloves and protective goggles is recommended.
Use appropriate working clothes, which is fully buttoned.
Before starting operation, the operator must make sure that he has removed the tools or
keys used for maintenance or adjustment.
In case of fire, the power supply should be switched off immediately and a dry chemical fire
extinguisher should be used.
NOTE : OPENING OR LEAVING THE PROTECTION HOOD OPEN WHILE
OPERATING THE MACHINE IS STRICTLY PROHIBITED AS WELL AS
DEACTIVATING THE SAFETY SYSTEMS.
7.- RECOMMENDATIONS AND MAINTENANCE.
- Type and periodical overhaul.
- A thorough acquaintance with the machine by the operator ensures the best possible
inspection of the machine. If any problem or defect is discovered, the work should be stopped and
the problem must be brought to the immediate attention of and solved by qualified personnel.
