GENERAL INFORMATION
WARNING!
–Carefully read all the instructions before performing any maintenance/repair procedure.
–Before using the battery charger, ensure that frequency and voltage values, indicated on the machine serial
number plate, match the electrical mains voltage.
–Do not pull or carry the machine by the battery charger cable and never use the battery charger cable as
a handle. Do not close a door on the battery charger cable, or pull the battery charger cable around sharp
edges or corners. Do not run the machine on the battery charger cable.
–Keep the battery charger cable away from heated surfaces.
–Do not use the machine if the battery charger cable or plug is damaged. If the machine is not working as it
should, has been damaged, left outdoors or dropped into water, return it to the Service Center.
–To reduce the risk of re, electric shock, or injury, do not leave the machine unattended when it is plugged
in. Before performing any maintenance procedure, disconnect the battery charger cable from the electrical
mains.
–Do not smoke while charging the batteries.
–To avoid any unauthorized use of the machine, remove the ignition key (if equipped).
–Do not leave the machine unattended without being sure that it cannot move independently.
–Always protect the machine against the sun, rain and bad weather, both under operation and inactivity
condition. Store the machine indoors, in a dry place: This machine must be used in dry conditions, it must
not be used or kept outdoors in wet conditions.
–Before using the machine, close all doors and/or covers.
–Do not allow to be used as a toy. Close attention is necessary when used near children.
–Use only as shown in this Manual. Use only Advance’s recommended accessories.
–Take all necessary precautions to prevent hair, jewelry and loose clothes from being caught by the machine
moving parts.
–Do not use the machine on slopes with a gradient exceeding the specications.
–Do not tilt the machine more than the angle indicated on the machine itself, in order to prevent instability.
–Do not use the machine in particularly dusty areas.
–While using this machine, take care not to cause damage to people or objects.
–Do not bump into shelves or scaffoldings, particularly where there is a risk of falling objects.
–Do not put any can containing uids on the machine.
–The machine operating temperature must be between +32°F and +104°F (0°C and +40°C).
–The machine storage temperature must be between +32°F and +104°F (0°C and +40°C).
–The humidity must be between 30% and 95%.
