☞ To avoid risks, become familiar with the machine
movements, carrying out test runs on a large sur-

To obtain the best results in terms of cleaning and
equipment service life, you should do the following
simple but important operations:
- Identify the work area, moving all possible obsta-
cles out of the way; if the surface is very extensive,
work in contiguous and parallel rectangular areas.
- Choose a straight work trajectory and begin wor-
king from the farthest area to avoid passing over
areas that have already been cleaned.
