consult the retailer or the manufacturer directly.
Install the unit on a flat and stable surface, capable of bearing the weight of the unit, the tools or objects which are

Do not start up the unit if: the power cable or plug has been damaged, the unit does not operate properly, it has been
damaged or if it has fallen.
In these circumstances there is the risk of electric shock, fire or other accidents. Do not attempt to adjust the unit per-
sonally, but instead contact only technical specialists or the manufacturer.
Do not immerse the power supply cable or plug in water. Keep the power supply cable away from hot surfaces.
Do not allow the supply cable to hang from the edges of tables or furniture units.
