Per the manual:
CARE AND MAINTENANCE
A. The firearm may be cleaned and lubricated under normal conditions
without the need of any disassembly.
B. In special conditions, such as repairs, when disassembling is necessary, it
is recommended the firearm be returned to the factory or sent to a competent
gunsmith or to the importer.
C. In order to keep a firearm in perfect condition it must be kept clean and
covered with a slight film of good quality oil to prevent corrosion. This is
especially necessary after use.
D. For normal cleaning of handgun not used or kept in storage for some time,
it is necessary to rub it with a lightly oiled cloth. In the same way proceed
with the bore of the barrel. The excess of oil must be removed, but a thin
protecting film should remain. Also the dust should be removed from all
crevices with a small, clean brush.
E. For cleaning after shooting, it is of special importance that all residues of
powder be removed from barrel and other adjacent areas subject to such
deposits, using an appropriate brush. If particles of lead are detected in
barrel they must be scrubbed with a brass brush, drenched with oil. Once
cleaned, lubrication should be done as above described. After shooting 200
shots in a row, your firearm should be cleaned before further shooting.
WARNING: Firing more than 200 shots in a row without cleaning your firearm
may create a hazardous situation.
