1. Important safety notes
1.5 Safety features
In order to enable you to work safely with our machines, we have incorporated the following safety
mechanisms. These meet the relevant European safety requirements.
■
Chuck protection hood
The main spindle of the machine operates only with the chuck protection hood closed. For safety
reasons, if the chuck protection hood is open, the machine cannot be switched on.
■
Gear cover hood
Always keep the gear cover hood closed. The gear cover hood may only be opened by a trained
person with a special key and when the grounded plug has been pulled out of the socket.
■
ON/OFF switch with under-voltage trigger
The ON/OFF switch is fitted with an under-voltage trigger, thus, in the event of a power failure, the
machine does not switch itself back on automatically. This prevents risks caused by the
unexpected motion of the spindle.
■
Emergency off switch
The emergency off switch acts to quickly stop the machine.
■
Overload protection
The machine is fitted with an overload protection feature. This overload protection feature switches the
main drive motor off automatically when the machine is overloaded. The machine can only then be
switched on after a waiting period
