the machine by non-authorised persons, the manufacturer's guarantee becomes void.

4 HEALTH AND SAFETY

4.1 Meaning of the symbols

In the instructions following symbols are used to warn the user against danger or special attention:

DANGER Danger because of the electric current!

WARNING General instruction, recommendation, forbiddance…!

www.sk-group.biz

4.2 General safety precautions

Due to its moving parts and to the pressure in the drum, the pneumatic press may be a threat to its environment.

Therefore, strictly observe safety precautions when operating the press. Unqualied and unauthorized person is not

allowed to use the press.

In a case of any unauthorised tampering with the machine, the manufacturer’s guarantee becomes void; furthermore, any

unprofessional repairs may result in danger for the machine operator.

If the pneumatic press is placed in such a way as to prevent a safe access to all its working positions,

additional aids and tools should be used, in order to guarantee a safe access to these working positions.

For a safe access, ladders, staircases and platforms with anti-slip surface and guardrails should be used.

Platform and staircases are manufactured in conformance with the following standards:

fDIN EN ISO 14122-1:2002; Safety of machinery - Permanent means of access to machinery - Part 1: Choice

of a fixed means of access between two levels

fDIN EN ISO 14122-2:2002; Safety of machinery - Permanent means of access to machinery - Part 2: Working

platforms and walkways

fDIN EN ISO 14122-3:2002; Safety of machinery - Permanent means of access to machinery - Part 3:

Staircases, stepladders and guard rails

Disconnect the press from the mains power ALWAYS:

fwhen it is not in use,

fbefore any intervention in the machine,

fduring the cleaning, control and maintenance procedure,

fin case of a damaged electrical cable,

fbefore opening the electric panel,

fin case of any danger.

In case of any danger stop the press by pressing the emergency STOP button or with the safety cord.

Before any intervention in the machine make sure that:

fthe press is disconnected from network,

fthe main switch of the press is in position OFF,

fthe drum is not pressurised.

Opening of the hatch during the press operation is explicitly forbidden.

The hatch may only be opened for the filling the drum, for the discharging, for cleaning

purposes and for maintenance works in the press drum.

Before opening the hatch manually, disconnect the press and turn the main switch OFF.

Before entering the drum, secure the door against unintentional closing.

Do not reach in the space between the drum and the press frame. Danger of squeezing!

This space is secured with a safety cord. The tension and position of the safety cord must be checked

before every use of the press.

Once a year, the screws that connect the membrane to the drum frame must be tightened. Before that,

disconnect the press from the mains supply. The hatch should be open and protected against inadvertent

closing.

When filling with the pump, be careful not to exceed the limit pressure value in the drum. You must

stop the pump as soon as you hear the acoustic signal, in order to reduce the pressure. Disregarding this

instruction can lead to serious damage of the drum.

When filling the press, the recommended filling capacity should be observed (see chapter 9.2 Filling of the press).

The press drum is subject to the requirements laid down in the pressure equipment directive PED 97/23/EC.

After setting up the press, the producer has performed acceptance examination with the initial pressure

test. The user has to consider all the directives, that are in force in the country where the press is operating.

The user must also make sure that all the periodical tests according to this directive are done.

4.3 Safety devices

The press is equipped with safety devices which ensure safe work and undisturbed operation of the press.

4.3.1 Emergency STOP button

When you push the emergency STOP button the

press immediately stops its operation.

Never use the emergency STOP to

interrupt the grapepress normal

running.

4.3.2 Safety cord

The space between the drum and the press frame is protected by a red safety cord. Any signicant vibration or pulling on

the cord triggers a micro switch, which in turn immediately stops the press.

Always check the safety cord tension and position prior to operating the press. If the safety cord is not installed or its

tension is incorrect, the press will not function.

The safety cord runs along the internal edge of the press frame.

It is connected to the S4 micro switch. The cord tension is proper

when the end of the black indicator is approximately in the

middle of the green strip, and the blue button pulled out to show

the green strip beneath it.

The cord tension is set by means of the screw at the cord end.

Any pulling on the cord triggers automatic immediate stopping

of the press.

The blue button drops.

The press switches to a standstill.

Prior to resuming the press operation, determine and remedy the

trouble that caused the press to stop.

To resume the press operation, lift the blue button on the micro

switch so as to show the green strip underneath it.

Start the press by means of the green button on the command

panel and resume the cancelled pressing programme.

4.3.3 Protection against overpressure in the drum

For protection against overpressure in the drum following safety systems are

used:

1 Maximum pressure that can be achieved with the compressor is limited

to 1.5 bar (by some press models maximum pressure is 1.8 bar).

2 In a case the pressure is exceeded (e.g. due to a valve fault), the

vacuum pump valve and the safety valve automatically open at 2.0

bar, to release air from the drum and to decrease the pressure to the

allowed level.

3 Presses with axial filling can also be equipped with a sound

alarm. The alarm is triggered if the pressure is exceeded or

the press is overfilled.

Make sure not to exceed the max. pressure allowed

douring the filling of the press.

In case the sound signal is activated, stop the lling

pump immediately.

4.3.4 Overload relays

The press has two overload relays (F1 and F2), which are

located in electric cabinet.

To open and close the electric cabinet, apply the

provided key. The key is xed to the cable on the cabinet

side at delivery.

The overload relay is activated in case of overloading, overheating or any

other trouble with the electromotor or compressor.

The overload relay F1 protects the drum rotation electromotor.

The overload relay F2 protects the compressor electromotor

By pressing the black button, the overload relay is reset.

ATTENTION!

Before resetting the overload relay, make sure that the problem that

caused the activation of the relay has been corrected/xed.

The presses with a built-in single-phase compressor have a circuit breaker incorporated in the compressor

itself. It is reset by pushing on the switch button.
