Handy Hints – cont.
Replace the spring on the piston, slide the piston back into the housing and
ensure the spring fits onto the housing. Slide the complete housing assembly
back into the drive housing. Turn the control knob all the way anti-clockwise to
relieve some of the spring tension, then screw on the locking nut being careful
not to damage the thread. Check the swirl valve for wear, if it is in good
condition slide into the housing, or fit a new one if it is worn. Screw on the spray
tip.
Plug in the sprayer, tip it upside down, and put a small amount of oil in the
suction hole (front hole) and trigger the sprayer briefly. This will coat the piston
and cylinder with oil and protect it from corrosion.
Refit the suction tube to the front port of the housing. Ensure the container is
clean and dry, screw it to the sprayer. The sprayer is ready for storage until the
next spray painting job.
If the sprayer is not cleaned properly and oiled after use, it may seize with paint
residue and corrosion. The warranty does not cover damage caused by improper
cleaning or corrosion.
