2.5Signs on the machine

2.5.1Types of signs

The machine has several types of signs: Safety signs show warnings related to potential hazards which could result in death or serious injury. Information signs show specific points related to the operation, maintenance or characteristics of the machine.

Nameplates are attached to components for which the machine serial number must be provided when ordering spare parts.

DANGER!

Failure to obey the safety plates! Death, serious injuries.

Do visual checks of the safety signs at intervals. Make sure they are all present and clearly legible.

Replace missing or illegible plates immediately. The ordering numbers of the plates are indicated in the spare parts catalogue of the machine.

2.5.2Arrangement of signs

* = Depends on the Note!

In order to be in accordance with specific local safety regulations, the safety signs may be different depending on the delivery country of the machine. For machines destined to the North American market (United States and Canada), there are specific safety signs. The meaning of the signs is explain in the chapter below.
