2.1 WORKING PRINCIPLE
The Double Mitre Saw, model T300/350, is a saw at vertical descent with blades at 45 degrees. It has been designed for the
cutting of frames for pictures , furniture, windows or looms.
The blades descent is controlled by a pneumatic system that clamps the mouldings on the working bench by means of 4
clamps.
The machine is equipped with a pneumatic device that allows a quick blades backstroke at low air consumption.
The directions of blades movement and rotation are represented on the picture 2.1 A
2.2 MAIN COMPONENTS
The main components, constituting the machine, are:
•Floor stand and working bench group
•Blades set at vertical descent on Z axis
•Padlockable air filter lubricator set
•Pneumatic system
•Electrical equipment
2.3 MACHINE STRUCTURE

2.10 TOOLS
2.4 DIMENSIONS
The overall dimensions are reported on complete drawing
of attachment 10.2-A
2.5 SURROUNDING CONDITIONS
The machine does not need special surrounding conditions.
It has to be installed inside an industrial building, lit, aired
and with a compact and flat floor. The admitted temperatures
go from 5° to 40° C, with an humidity not higher than 50%
at 40° C or 90% at 20° C.
2.6 LIGHTING
Premises lighting must be conformed to the norms in force
in that Country where the machine is installed and has to
guarantee a clear visibility, do not create dangerous
reflections and allow a clear reading of the control panel
and the location of emergency button.
2.7 VIBRATIONS
In standard conditions conformed to the indication of
machine proper utilization (the machine is anchored to the
ground by 4 fastening points), the vibrations do not create
dangerous conditions.The average quadratic weighed level,
according to the acceleration frequency to which arms are
exposed does not exceed 2,5 m/s2.
2.8 NOISE EMISSIONS
The machine is designed and projected for reducing the
noise emission level to its source. Tests have been effected
according to the measurement method conformed with Art.
46 D.Lgsl. 277/91.
The T350 Double Mitre Saw , when workings on standard
and correct conditions of use, produces a sound level per
operator lower than 85 bB (A) even if used continuously.
For this survey has been considered the cut of hardwood
type Ramin which can be used for manufacturing of picture
frames. The use of softer woods (i.e. Obeche) produces
sound levels lower of about 2-3 dB (A).
The noise levels indicated are emission levels and are not
representing sure operating levels. In spite of existing a
relationship among emission levels and exposure ones, this
can not be used in a reliable way to define if further cautions
are necessary. The factors determining the exposure level
to which the working force is subjected, include exposure
lasting, working premises characteristics and other noise
sources (number of machines, closed proceeds, etc…).
Furthermore, also the allowed exposure levels could change
according to the several Countries. At any rate, the
information provided, will allow the Machine Operator to
achieve a better evaluation of danger and risks he is
submitted to.
Blades, conformed to the Norm EN 847-1
The indicated noise levels are emission ones
measured in standard conditions of use. In
case of any machine modification, the above
mentioned levels could be changed and
should be settled directly on the same
machine.
Blades, conformed to the Norm EN 847-1, have the
following dimensions:
•A =30 mm
•B =300 mm (model T300 – T300/A)
=350 mm (model T350 – T350/A)
=400 mm (model T400)
•Thickness =2.50 mm
Use the machine only if equipped with
special individual protections for hearing (
headphones etc…).
The customer can request different types of blades
according to the materials to be cut (light alloys,
wood or plastic).

PRELIMINARY 05.1998
3.5 PROTECTION DEVICES
The machine is equipped with adequate protections for persons exposed to the risks due to the of mobile elements of
transmission (blades, pulleys, belts, etc.…), or mobile members taking part in working (blades) or ejection of wooden
pieces, chips, or dust.
3.6 STOP FUNCTIONS
The machine stop functions are the following:
•General Switch (category 0)
•Normal Stop Button (category 1)
•Emergency Button (category 1)
STOP CATEGORY 0
Is obtained taking out power from Machine actuators (uncontrolled stop)
STOP CATEGORY 1
Controlled stop with opening of power supplying for the machine actuators after of such a period allowing the stop of them.
3.7 SAFE WORKING PROCEDURES
The machine is projected and realised with the purpose of eliminating any risk connected with its use.
Owing to the necessity of steering the moulding around blades working area, it is impossible to eliminate the risks related
with possible accidental contacts of operator hands with a.m. area.
The other risks related with manual working mode, are:
•Cut (due to the contact of the operator hands with the blades)
•Entanglement (due to clothes not properly tight)
•Ejection of worked material chips
To drop down to the minimum the consequences of above mentioned dangers, it is necessary to follow carefully the following
instructions:
1 when the hands are working closely to the blades, you have to steer the moulding to be cut using any tool
2 avoid the cutting of moulding pieces smaller than 50 mm
3 never use hands to take out the short pieces and/or cuttings close to the blades, but instead use a tool, i.e. a piece of
moulding still to be cut
4 adjust the frontal protection according to the height of cutting pieces and clamp in position
Operate as follows for adjusting the B protection guard of picture 3.7
•unscrew the A knob of picture 3.7
•lift or lower the B guard according to the height of mouldings to be cut
•tighten the guard in the proper position by screwing the A knob
Owing to the residual risks related with the machine, it is necessary that at the beginning the user of the
machine should be properly trained and assisted by Alfamacchine’s qualified personnel
When finished your work, lower completely the protective guard

•Risk of being hit by tool used for manual unlocking of the blades
•Risk of cutting because of accidental contact with blades in motion or stop, i.e. during their replacement
•Error of assembly, i.e. because of blades assembly in opposite sense or mistaken electric connection (rotation in the
opposite sense)
•Risk due to the presence of power supply on the machine

When the motors are running it is necessary:
•Check that right blade rotation sense is counter-clockwise
•Check that the left blade rotation sense is clockwise
It is strongly imprudent to make a cutting test before checking the blades rotation sense.
In case of reverse rotation, the operator risks the projection of material on his face and body.
