Storing
 If you do not use the spray gun for a longer period of time, lubricate the
complete spray gun from inside and outside with a little thin-fluid, acid-
free oil. Before next use, fill the paint container with a little thinner and
blow it with compressed air through the spray gun in order to remove
the oil.
 Store the spray gun indoors in a dry place that is protected from dust
and dirt.
