To improve the sound insulation performance in a factory still more, use the interior finish materials which show high sound insulating performance for the walls, ceiling, and floor of the factory. Install the machine on a sturdy floor. The floor structure must be strong enough to bear the machine weight (indicated on the spec. plate). Avoid dust and moisture. Since dust and moisture lead to dirt and rust on the machine, use the machine in an environment of facility of air conditioner, and clean the working place periodically. Use caution not to expose the machine to direct wind from the air conditioner so that embroidery threads do not become disheveled. Humidity: 30 to 95%RH (relative humidity) without condensation Ambient temperature: 5 to 40°C (during operation), -10 to 60°C (during storage) Avoid direct sunlight. If the machine is exposed to direct sunlight over an extended period of time, the machine body may be discolored or deformed. Put curtains or shades to the site to prevent the machine from direct sunlight. Provide enough space for maintenance. Taking account of workability when maintaining and inspecting the machine, provide working area of 50 cm or more to right and left, and 55 cm or more to rear directions of the machine against obstacles such as walls. Pay attention to interference of radio wave. Although the machine is designed not to affect radio wave interference to other equipments, there could be cases where it causes interference depending on operation environment and type of other equipment. If such problems arise, install the equipment with a space from the machine as big as possible. CAUTION ! 55 cm 50 cm 50 cm RR03
