If during work the spray pattern becomes uneven or material stops coming out of
the gun, release the trigger and lock it in the closed position. Then turn the spray
nozzle by 180 so that its "dart" points in the direction of the gun (in the cleaning
o
position) - see the picture below.
NOTE: under pressure the nozzle may not be able to be turned easily, so turn the
valve switch to the "Air release/Cleaning" position and squeeze the trigger, this will
release the pressure from the nozzle and allow it to be turned more easily.
IMPORTANT: do not use a needle or any sharp object to clean the nozzle, because
it can be damaged!
Next, turn the valve knob to the "Spraying" position and spray in the direction of
some test piece, allowing the pressurized air to blow away the deposits. If this
happens, a steady stream of material should immediately come out of the nozzle.
Then lock the trigger, rotate the spray nozzle with the arrow toward the surface to
be sprayed, and once the trigger is unlocked, you can continue working. However,
if this method does not improve, clean the spray gun filter (see next section).
3.4.2 Cleaning the spray gun filter
CAUTION: The spray gun filter should be cleaned after each use, but more frequent
cleaning may be needed if thicker paints/paints are used.
First, remove excess pressure according to the method described above in the text.
Unscrew the tip at the bottom of the handle from the gun taking care not to lose
the spring. Next remove the trigger guard by pulling it from the gun in the direction
of the spray tip. Remove the filter from the gun housing and wash it thoroughly (use
an appropriate agent depending on the type of paint sprayed). Inspect the filter
strainer for holes and - if there are any, replace it. Attach the cleaned filter with its
tapered tip back to the gun, making sure that everything is tightly fitted, as only this
will ensure its efficient operation.
