CLOGGED FLAT TIP
Should the spray tip become clogged, relieve pressure
from hose by following the "PRESSURE RELIEF
PROCEDURE." Secure gun with the safety latch, take
off guard, take out the tip, soak in appropriate solvent &
clean with a brush. (Do not use a needle or sharp pointed
instrument to clean the tip. The tungsten carbide is brittle
and can chip.)
CLEANING SPRAY GUN
Immediately after the work is finished, flush the gun out
with a solvent. Brush pins with solvent and oil them lightly
so they will not collect dried paint.
To clean the filter, use a brush dipped in an appropriate
solvent. Change or clean filters at least once a day. Some
types of latex may require a filter change after four hours of
operation.
