Operating, maintenance, spare parts manual Rel. 3 dated 02/07/2019 Pagina 28 di 54
5.9 Training
Before starting to use the machine, read this instruction manual and understand how to use
the machine in a safe way.
6 ADJUSTMENTS
6.1 Adjusting the machine
At first operation on the building yard, the machine does not need any adjustments. However, we suggest to read the
following paragraph:
5.4 Pre-operation checklist.
Never carry out adjustments while the machine is running/working.
Do not alter or bypass any active safety devices installed on the cutting machine.
Follow the safety instructions shown in chapter SAFETY PRECAUTIONS.
Every single adjustment and/or modification of the safety/work parameters set on the machine, which has not been
authorised by the technical personnel of the company Silla or which is not outlined in this instruction manual, may
influence the quality of the product and injure the operator’s health. The company Silla decline any responsibility for
liability, performances and safety of the machine in case of modification/alteration of the machine and of the relevant
operation/safety parameters.
7. OPERATION
7.1 Control instruments
The START and STOP push-buttons are placed on the main casing of the Cutting Machine.
The STOP and the Emergency STOP push-button is installed next to the START push-button in a clearly visible way, in
order to stop the machine at any time. To disengage it, turn it clockwise.
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.

“START” push-button to start the machine.
Caution! If the protection case of the cutting unit is not closed, the machine will not work.
Do not alter or bypass any active safety devices installed on the cutting machine.
6 –Pull the lever to cut.
7.3.2 Stopping the machine
To switch off/stop the cutting machine, press the emergency stop push-button and cut the electric power supply or unplug.
Keep the cutting machine always switched off when you do not use it.
The operator shall always be careful and concentrate on what he is going to do and on the possible consequences.
7.3.3 During operation
Use the prescribed personal protective equipment.
Never approach the moving and operating elements with your hands, arms or other parts of your body. Remove rubble with
an appropriate device and always when the machine is stopped: never use your hands! In case of accident, press the
STOP push-button and lift the lever in to home position, the oil will automatically come out from the cylinder and
the cutting unit will automatically return into its home position. The same operation shall be repeated if one ore
several bars should jam inside the bar cutting unit.
In case of machine trouble, or something to check, stop the machine and immediately disconnect it from the electric
installation.
During the operation of the machine, of its elements or of its accessories, it is strictly forbidden to remove any protection,
safety switches, carters, barriers or other protection and safety elements. Never modify switches or other safety and/or
operating cycle control devices, because such an intervention could seriously damage the mechanical elements of the
machine and injure the health of the operator.
Pay attention to the operating and the moving parts.
Do not climb or position yourself on or inside the machine, even if it is switched off.
In case of machine trouble, stop the machine with the emergency stop push-button and cut off the electric energy supply
until the trouble has been eliminated.
The operator is the person entitled to operate with the machine and consequently he is the only responsible for it.
