WORK PLACE
In normal working conditions the operator must stand always outside of the machine (see
Error! Reference source not found. and below), in such a position where he/she can see the
entire machine and the working table. The “DANGEROUS AREA” of the machine comprises the
areas where the mobile units operate and also the area close to them.
The necessary working space for a correct use of the machine is 1500mm at minimum all
around the machine. In the following Figure 4 you can see the main safety areas around the
machine, where the operator must pay particular attention to persons and things which can
represent obstacles or a dangers for normal workig operations.

Figure 4 - Dangerous area and safety space
If the machine is used for continuous cutting or has a rolling support for workpiece, it is
necessary to leave a minimum free room of 1500mm on each side above the maximum
encumbrances of the machine.
The personnel must stay well away from the DANGEROUS AREA when the
machine is working
Install suitable delimitation devices in the frontal part, side parts and rear part of
the machine to avoid that the personnel get in touch with the movable parts of
the machine when the machine is working.

WORKING TABLE
The working table consists of a thick-gauge cast iron structure, mechanically attached to the
lower steel frame, with a plate which is able to rotate on the vertical axis. This allows angled
cuts to be made, from 0° to 67.5on the LH side and from 0° to 67.5on the RH side.
It is possible toget in touch with the working table by lifting up the steel-made upper safety
guard, using the lifting handle. A safety switch cuts the electric power and disables the rotation
of the cutting blade when the upper cover is lifted.

For setting up the desired cutting angle, lift-up the upper safety guard using the handle (point 7
and point 8 in Figure 8) and follow the instructions below:
-loosen the handle A
-push the button Band rotate the head until you reach the desired cutting angle. Use the
fixed reference points (67.5° - 60° - 45° - 0° - 45° - 60° - 67.5°) or aling the reference index

CUTTING UNIT
This assembly consists of a cast iron structure for the transmission between the motor and the
blade and a set of mountings for the cylinder that controls the blade outward movement through
the rotating working table.
Te unit is located in the lower part of the machine, inside the steel frame.
The blade movement is powered by a hydraulic-pneumatic cylinder with a two-handed control
device which keeps both the operator’s hands occupied during the cutting operation (see
buttons SB1and SB2in Figure 7).

Before carrying out any maintenance work, make sure the machine is

SINGLE MITRE SAW 50
ENG Rev 1

ATTENTION
The blade has not a brake: its stop is NOT immediate but it needs some time for
a complete stop. The time needed for a complete stop depends from its
revolving speed, of the type of work, of the working material and of the
characteristics of the tool used (shape, dimensions, weight).
Do NOT get close to the cutting until the blade is completely stopped.
Do NOT operate if machine parts are still in motion, only after that the machine
is disconnected from any power source and that any residuals energy is
completely dissipated.
DANGER OF CUT AND BURN.
Wear always protective gloves before handling and/or working with tool
DANGER OF BURN: do not touch tool just before end working. Wait for the
temperature has slow down before touching it.
Follow the values given by the manufacturers of the tools used for the maximum
allowed speed values and the correct cutting parameters related to the material
to be cut and the type of work to be done.
Never use tools at speed higher than the one allowed.
ATTENTION
Use only blades with the characteristics as specified in this handbook
IT'S MANDATORY to use anti-noise Widia blades, which have lower noise
emission levels than normal blades.
MAXIMUM BLADE OUTSIDE DIAMETER for working in safety conditions:
500mm (standard machine)
NEVER use blades with different dimensions as those specified in this
handbook

does not respect what the requests of the manufacturer

2.5.1.
SETTING THE BLADE FEEDING SPEED
The feeding speed of the cutting unit can be regulated depending the material to be cut. To
regulate the feeding speed (from 0 up to 0.40 m/sec) use the knob placed on the right side of
the machine (RV in Figure 7). The operator can vary the speed rotating the knob clockwise
(speed down) or counterclockwise (speed up), acting directly to the flow distributor coupled with
the feeding actuator.
Figure 11 –Feeding speed regulator
2.5.2.
SETTING THE BELT TENSION
The tension of the transmission belt between the electric motor and the blade is correctly
regulated by the manufacture. Anyway, sometimes, it could be necessary to perform again this
operation. To set correctly the tension of the belt:
-loosen the 4 screws using the forck key and remove the front cover of the steel frame
Figure 12 –Front steel frame cover removal

SINGLE MITRE SAW 50
ENG Rev 1
page 18
-remove the cover of the transmission belt CP
Figure 13 –Setting the belt transmission tension
-loosen the screws which locks the electric motor EM on the support
-push on the motor EM until the belt reaches the desired tension level
-tighten the screws of the electric motor EM
-mount again the cover CP and lock it in position using its screws
-assemble again the front cover of the steel frame and tighten its locking screws.
