Proper use includes:
● Using the device in accordance with the permitted ambient temperature according to the rate plate.
● Operating the device with all protective features in place.
● Minding the operating instructions.
Improper use:
Using the device in the following ways is particularly prohibited and may cause hazards:
● Operating the device with an imbalance, e.g. caused by dirt deposits or icing.
● Moving air that contains abrasive particles.
● Moving highly corrosive air, e.g. salt spray mist.
● Moving air that contains dust pollution, e.g. suctioning off saw dust.
● Operating the device close to flammable materials or components.
● Operating the device in an explosive atmosphere.
● Using the device as a safety component or for taking on safety related functions.
● Operation with completely or partially disassembled or modified protective features.
● In addition, all application options that are not listed under proper use.
