and eventually replace.
Check connection to the compressor.
Verify pressure parameters and setting.
Check, clean or replace.
Check the connections and condition of pipes up
to the outlet end (nozzle).
Check compressor features: the minimum
capacity must be of at least 150 liters per minute
(to assure steady power) and a tank of 100 liters
(to assure autonomy).
Comply with references stated in the table
