SAFETY INDICATIONS

WHAT TO DO:

Make sure that mains voltage corresponds to the voltage indicated on CE plate and that cable of suitable cross-section are

used for electric connections.

Always check oil level  before starting the compressor.

Be familiar with emergency stop control  and all other controls.

Empty the air tank and/or  oil separator and unplug the connector before any maintenance work, so to avoid accidental start.

Ensure that all parts have been correctly reassembled after any maintenance work.

Keep children and animals off the working area  to avoid injuries caused by devices connected to the compressor.

Carefully read instructions for the installed accessory, especially if painting devices are installed.

Ensure  that the installation place is properly ventilated.

Ensure  that temperature of the working environment ranges b5 and + 45 ºC.

The compressor should be installed and operated in a non-explosive environment.

Allow at least 50 cm  between the compressor and the wall so to allow free air flow to the fan.

Press the emergency button on the control panel only in case of actual need so as to avoid possible damages to people or the

very compressor.

When calling for technical assistance and/or advice, always mention model and serial number indicated on CE plate.

Always follow the maintenance schedule specified in the user’s guide.

WHAT NOT TO DO:

Do not touch inner parts and pipes as they are very hot during compressor operation and stay hot  for a certain time after

compressor stop.

Do not position  inflammable or nylon objects or cloths close to and onto the compressor.

Do not  move  the compressor when the tank is under pressure.

Do not operate  the  compressor if the power cable is damaged or defective or if connection is unstable.

Do not operate  the compressor in explosive environment or in case of naked flames.

Do not operate the compressor in wet or dusty environments.

Never aim    the air jet at people or animals.

Do not allow unauthorized people to operate the compressor and give them all required instructions.

Do not hit fans with blunt objects as they might break during compressor operation.

Never operate the compressor without air filter.

Do not tamper with  safety and adjusting devices.

Never operate the compressor when doors/panels are open or removed.
