Cleaning And Maintenance - Defort DSG-80N Instrucciones De Servicio

E
Never start or stop the spray gun while it is aimed at
the surface to be sprayed. Evenly control the speed of
movement of the spray gun. A fast speed of movement
over the surface will give a thin coat and aslowspeed
will givea heavy coat. Apply one coat at a time. If a fur-
ther coat is required, make sureyou observe the manu-
facturers drying time recommendations before apply-
ing a second coat. When spraying small areas, keep
the output control on a low setting. This will avoid using
too much paint and prevent overspray. Where possible,
avoid stopping and starting when spraying an object.
This can lead to too much, or not enough paint being
applied. Do not tip the spray gun to more than 45°

CLEANING AND MAINTENANCE

Always remember to disconnect from the
mains supply before cleaning the spray gun
or paint container.
It is essential that the spray gun is cleaned thoroughly
after every use. Failure to clean it will almost certainly
result in blockages and it may not operate when you
next come to use it! The guarantee does not cover
cleaning a sprayer that has not been properly cleaned
by the user.
The following action must be taken after every
use.
1. Empty any remaining material from the container.
2. Clean the container thoroughly with the thinner
thatwas used.
3. Pour some thinner into the container and spray
through the spray gun until only clean thinner is
coming out of the nozzle.
4.Thoroughly clean the paint pick uppipeand fi lter with
thinner.
5.Clean the basket and nozzle and remove any other
debris or paint that remains.
6. Turn the spray gun upside down and apply a few
drops of light oil to the two apertures (F). This will
lubricate the piston and cylinder.
If your spray gun should require extra internal
cleaning, it may be necessary to disassemble it. If
so the following action should be taken.
1. Remove the plug from the mains socket.
2. Remove paint container, pick up pipe and fi lter.
3. Release the nozzle (H), valve (j), piston (K) and
spring (L).
4. Clean the cylinder (M) and all parts thoroughly with
solvent.
5. Apply a few drops of light lubricating oil to the pis-
ton, springand cylinder.
6. Reassemble the spray gun.
