4.4 Noise

the noise emission level of the Cutting Machine measured at the operator’s ear does not exceed the

maximum value of 63 Pa, according to UNI 11200 standard

In order to not increase the noise level strictly follow these rules:

Clean and grease the machine elements per the schedule recommendations;

Ensure the machine parts are not obstructed or damaged.

With this noise emission level the use of protective equipment like earmuffs, earplugs, etc. is not mandatory but

recommended.

These noise values are emission levels and are not necessarily safe work levels. While there is a correlation between the

emission levels and the exposition levels, it cannot be used in a reliable way to evaluate whether there is or nor the need for

additional precautions. The factors affecting the worker’s real exposition level include the duration of the exposition, the

environmental characteristics, other emission sources like for example the number of adjacent machines and types of

machining. The single exposition levels may also differ from country to country. However, thanks to this information the user of

the machine can better evaluate the dangers and risks.

The lever control placed on the upper side of the machine, allows the operator to carry out cutting operation by simply

pulling the lever towards him. The control lever activates the cut because the oil enters the hydraulic cylinder.

The control lever automatically returns into home position. The return of the cylinder is possible, even if the blade did not

finish its stroke; you simply need to turn the lever into home position and the circuit reopens, thus allowing the return of the

cutting unit.

During operation, follow the safety instructions shown in chapter SAFETY PRECAUTIONS.

7.2 Machine operation and controls

7.2.1 "START" push-button.

It is used to start the oil-pressure pump or to reinitialise it after the emergency stop push button has been

pressed and after power cutoffs. The oil-pressure pump does not automatically start after a power cutoff; it is

the operator who must decide to start it again.

7.2.2 Emergency stop push-button

It cuts the power supply to the electric motor, which starts the oil-pressure pump in case of need. The push-button is of type

“mechanical interlock with rotary disengagement”; to disengage the push-button it must be turned cw.

Another emergency stop push-button is placed on the machine opposite side in order to stop it at any time.

Do not “play” with the emergency stop push-button. Use these buttons only for the use they have been

designed for.

7.2.3 Lever control

The lever control placed on the upper side of the machine, allows the operator to carry out cutting operation by simply pulling

the lever towards him. The control lever activates the cut because the oil enters the hydraulic cylinder.

The control lever automatically returns into home position.

The return of the cylinder is possible, even if the blade did not finish its stroke; you simply need to turn the lever into home

position and the circuit reopens, thus allowing the return of the cutting unit.

7.2.4 Knob control

The models S 36 - S40 - S45 -S50 –S55 also have a knob, placed on a machine side, for manual or automatic mode selection.

By lowering this knob, before pulling the lever, you can set continuous cutting cycle. Consequently, after pulling the lever once,

you can carry out cuts without the need to pull the lever again. All this is possible thanks to a mechanism that closes the o il

circuit inside the cylinder, after the return of the arm of the cutting machine, thus starting a new cutting cycle.
