Double Mitre Saw T2300-T2350-T2400 - T2450
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 at oor. 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 reections 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 eected
according to the measurement method conformed with Art. 46 D.Lgsl. 277/91.
The T2xxx 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 dene 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.
The indicated noise levels are emission ones measured in standard conditions of use. In case of
any machine modication, the above mentioned levels could be changed and should be settled
directly on the same machine.
Use the machine only if equipped with special individual protections for hearing (headphones etc…).

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:
• when the hands are working closely to the blades, you have to steer the moulding to be cut using any tool
• avoid the cutting of moulding pieces smaller than 50 mm
• 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
• adjust the frontal protection according to the height of cutting pieces and clamp in position
Operate as follows for adjusting the A protection guard of picture 3.7
• unscrew the B knob of picture 3.7
• lift or lower the A guard according to the height of mouldings to be cut
• tighten the guard in the proper position by screwing the B knob (picture 3.7)
