Precautions Against Residual Risks - Mitsubishi Electric MEGR Manual

Only use the machine with the safety devices properly installed and in perfect working order. Failure to observe this requirement
could result in serious risks to the health and safety of the persons involved.
Keep the machine in perfect working order and perform the routine maintenance recommended by the manufacturer. Good
maintenance can help to ensure the best possible performance, a long useful life and constant compliance with the safety
requirements.
Before maintenance and adjustments, activate all the applicable safety devices and provide the personnel and any other people in
the vicinity with all necessary information. In particular, cordon off the area and prevent access to all the devices that could, if
activated, inadvertently cause danger and pose risks to health and safety.
Maintenance and adjustments must be carried out by authorised persons who must implement all the necessary safety measures
according to the procedures set down by the manufacturer.
All maintenance operations that require specific technical expertise or skills must only be carried out by qualified personnel with
recognised experience in the field.
In the case of maintenance in areas that are awkward or dangerous to access, implement appropriate measures to ensure the safety
of oneself and of other people, in compliance with the laws in force on safety at work.
Replace excessively worn parts. All the above can help to ensure the good working order of the machine and the required level of
safety.
This appliance must not be used by persons (including children) with reduced physical, sensory, or mental capabilities, or lack of
experience and knowledge, unless they are supervised or given instructions.
Children must be supervised to make sure they do not play with the appliance.
