USE AND INSTALLATION MANUAL

1.2.3. RESIDUAL RISKS

Using the machine involves some risks which cannot be completely eliminated through design or with the

installation of adequate protective devices. However, the manufacturer has undertaken to inform the operators of

these risks in this manual by specifically indicating the personal protective equipment to use. When repairing the

machine, adequate space has been provided to limit these risks.

To maintain these conditions, the areas around the machine must always be:

- obstacle-free (e.g. ladders, tools, containers, boxes, etc.);

- clean and dry;

- well-lit.

For the sake of providing the customer with comprehensive information, the residual risks remaining on the

machine are indicated below: these actions are deemed inappropriate and are, therefore, strictly forbidden.

Residual risk

Description of hazardous situation

Slipping or falling.

The operator may fall due to water or dirt on the floor.

Burns/grazes (e.g. from hot components).

The operator deliberately or involuntarily touches parts

inside the machine without wearing protective gloves.

Electrocution.

Touching live parts while servicing the machine when the

electrical control panel is powered.

Overturning of heavy loads.

When handling the machine or the packaging that

contains it, inadequate lifting systems or accessories are

used or the load is unstable or unbalanced.

Mechanical features of safety devices, risks

•The machine does not have any sharp or protruding parts. The protective devices for the mobile and live

parts are screwed onto the structure and cover to prevent accidental access.
