10 MAINTENANCE
Inspections frequenty
Perform an inspection every 6 months minimum.
The frequency, however, depends on the use.
In the event of frequent use it is recommended to
plan inspections at shorter intervals:
frequent use (continuous or very intermittent
use, near the operating limits, etc)
critical use (service necessary)
in highly aggressive environments such as
industrial environments with concentrations
of combustion fumes or chemical
substances
highly polluted urban environments
rural areas with concentrations of
fertilizers, livestock manure, diesel engine
exhaust gases
coastal areas
