Operations
Cutting operation
1. Connect the pressure-air supply on
the plug C (Fig 5).
2. Clamp the material to be cut firmly to
the working base by turn on the
switch D (Fig 6) keeping it pressed
against the fence so that it cannot
move during the cutting operation.
3. Push green button of main switch E
(Fig 7).
4. Use the handle F (Fig 7) to lower the
blade until it comes into contact with
the material to be cut, then push
grad gradually until you have
completed the desired cut.
1. Pushing down harder on the
handgrip does not necessarily mean
that you will cut faster; in fact this
can lead to the motor overloading,
resulting in less efficient operation.
2. When you have completed the cut,
turn off the motor by releasing the
button and guide the saw/motor arm
back to its idle position.

Setting and Adjustment
Adjustment of the table angle
The turntable can be turned right or left.
It is semi automatically blocked at 15
degree, 22-1/2 degree, 30 degree, 45
degree and in center position at 90
degree.
In order to turn the table to these
positions, first release knob H (Fig 8) if it
is tightened. Pull up lever G (Fig 8) and
turn the saw-motor arm. When the fixed
pointer located on the base is indicating
the required setting of the scale (printed
on the turntable), release lever G to
block the turntable in the setting. The
lever will flick back to its start position.
Also tighten down knob H to prevent the
machine from shaking during operation.
Attention:
1. Move the saw-motor arm left or right
to make sure it is firmly secured in
place.
2. Angles between the semi-automatic
settings are obtained by blocking the
rotating table with knob G.

Adjusting the arm angle
The saw-motor arm can only be tilted
leftwards to a maximum angle of 45°
(end of the stroke), but the turntable can
be tilted to any angle.
The arm is tilted as follows:
1. Unlock the screw, L (Fig 10), at the
back of the machine.
2. Tilt the saw-motor arm as
requested using the handgrip. The
angle can be checked on the scale
printed next to the hinge for
rotation. Once you have tilted the
arm enough, lock the screw again
(Fig 11).

Maintenance
Maintenance must be carried out by
qualified staff. The various operations
for the ordinary and extra ordinary
maintenance are indicated in the last
pages of this manual.
It is compulsory to switch off the general
electrical equipment, when it is
necessary to adjust the machine or to
disassemble any protection, by pointing
out such operation through a clearly
visible placard.
An important security factor is the
cleaning of the machine, of the working
tables, of the floor and the surrounding
places.
It is very useful to read carefully through
this manual before starting the machine:
1. In this way you will realize that the
machine has been concerned to offer
the best performances together with
the highest security.
2. Encumbering and mobile objects,
which could come into contact with
the moving organs, are very
dangerous.
3. A certain risk factor, which is
eliminable with a good technique and
with a constant attention by your side,
exists in every work.
4. Before starting the machine, make
sure that there are no other people
carrying at maintenance operations.
Other risks
In spite of the adopted security
directions, some other risks could
remain.
1. Due to high R.P.M. of the blade,
although precautions (like guards)
are adopted, that could be rejected if
wrongly fitted therefore pay attention
while fitting the blade.
2. A protracted sonorous exposition
could provoke health troubles.

Troubleshooting
Problem
Probable Cause
Solution
Teeth breaking
Incorrect lubricant/coolant
fluid
Ensure proper coolant flow.
Material too hard
Check the cutting speed, feed speed and air
pressure parameters and the type of blade you
are using.
Disc not worn--in correctly
With a new blade it is necessary to start cutting
at half feeding speed. After the wearing--in
period (a cutting surface of about 300 cm2for
hard materials and about 1000 cm2for soft
materials) the cutting and feed speeds can be
brought up to normal values
Disc with excessively fine
tooth pitch
The dwarf wedges into the bottom of the teeth
causing excessive pressure on the teeth
themselves
New blade inserted in a
partially completed cut
The surface of the cut may have undergone work
hardening. When starting work again, use a
lower cutting speed and head feed speed. A
tooth from the old blade may be left in the cut:
check and remove before starting work again.
Work piece not clamped
firmly in place
Any movement of the work piece during cutting
can cause broken teeth: check the vise, jaws and
clamping pressure.
Rapid tooth wear
Feed speed too slow
The blade runs over the material without
removing it: increase feed speed.
Cutting pressure too high
Reduce cutting pressure.
Blade speed too high
The teeth slide over the material without cutting
it: reduce the blade speed.
Insufficient coolant
Check the coolant level and clean coolant lines
and nozzles.
Incorrect fluid concentration
Check and use the correct concentration.
Material defective
The materials may present altered zones either
on the surface, such as oxides or sand, or in
section, such as under-cooled inclusions. These
zones, which are much harder than the blade,
cause the teeth to break: discard or clean these
materials.
Broken blade
Feed speed too high
Reduce blade speed.
Teeth in contact with
material before starting the
cut
Always check the position of the blade before
starting a new job.
Insufficient coolant
Check the coolant level and clean coolant lines
and nozzles.

16
Troubleshooting
Spindle motor will not
turn
Electrical power supply
Check: the cables, plug and socket. Also check
that the motor connections are in place.
Transformer
Check that the voltages are present both on the
input and output. Otherwise replace.
Contactor
Check that the phases in it are present both on
the input and output, that it is not jammed, that it
closes when powered and that it is not causing
short circuits. Change if any of these problems
are found.
Thermal relay
Make sure it is closed, i.e. check that the phases
are present in input and output that it is not
causing short circuits and responds when the
reset coil is closed. If it has tripped to protect the
motor, check the amperage setting, reset, and
check the motor. Change if necessary.
Motor
Check that it has not burnt out, that it turns freely
and that there is no moisture in the connection
terminal board box. The winding can be rewound
or replaced.
