Handy Hints – cont.
To assure trouble free service from the sprayer, always remember these
simple steps.
Strain old paint before using.
Be sure paint suction tube is tightly inserted.
Thin paint properly
Use the correct swirl valve and spray tip for the paint.
Watch for wear of the swirl valve and spray tip.
Some paints are much more abrasive than others and will cause quicker wear of
parts. Spray tips, swirl valves and pistons are wearing parts.
Spray tips - Water based paints are especially abrasive. If you notice that the
paint is not atomising as well as it should and the sprayer starts spitting, the
spray tip orifice has become too large and the spray tip should be replaced.
Swirl valve - After paint has been sprayed, the swirl valve may become worn.
The paint may not atomise as well as it should and the sprayer may start spitting.
When the valve is worn, the holes will be larger and the sealing block will be
‘furred’ or scratched. If the spray tip has been over-tightened the swirl valve
head may be damaged.
