141. Important safety notes1.5 Safety features1.5.1 for all milling machinesIn order to enable you to work safely with our machines, we have incorporated the following safetymechanisms. These meet the relevant European safety requirements:■ Protective hoodThe protective hood is secured to the machine housing and is designed to prevent touching of therotating tool spindle. The protective hood is constructed in such a way that the working height(depending on the dimensions of the work piece and tool) can be adjusted. The protective hoodcan be swivelled to enable fast exchange of tools.■ ON/OFF switch with under-voltage triggerThe ON/OFF switch is fitted with an under-voltage trigger, thus, in the event of a power failure, themachine does not switch itself back on automatically. This prevents risks caused by theunexpected motion of the tool spindle.■ Emergency off switchThe emergency off switch acts to quickly stop the machine.■ Overload protectionThe machine is fitted with an overload protection feature. This overload protection featureswitches the main drive motor off automatically when the machine is overloaded. The machinecan only then be switched on after a waiting period.1.5.2 for Milling machines with CNC control assembly and CNC milling machines■ Safety cabin (optional)In CNC mode, the door to the safety cabin must be closed in order for the milling machine to workin CNC operation.You can only work in CNC mode with the doors closed.Work carried out in conventional mode is carried out with the door open. The mode switch must beswitched to manual mode.The main spindle can be switched on when the doors are closed or open.Working in CNC mode without safety cabin may pose a serious risk to the machineoperator and cause serious accidents.1.5.3 for CNC milling machines■ Switch for operating modesThe mode switch has 3 settings (CNC mode – Idle position – Manual mode) that can only beselected with a key. After selecting the mode, the key can be removed in order to prevent aswitching of the mode type by unauthorised persons.
