OPERATION INSTRUCTIONS
PREPARATION
Do not use textured wall paints or coatings as
this wHIblock the nozzle.
To obtain the best results, it is important that you pre-
pare the surface to be sprayed and thin the paint to
the correct viscosity, before you operate your spray
gun. Always ensure that the surfaces to be sprayed
are free from dust, dirt and grease. Make sure that you
have masked the areas that should not be sprayed,
using a good quality masking tape. The paint or fl uid
to be sprayed should be thoroughly mixed and free
from lumps or other particles. Many substances can
be sprayed with your spray gun, but always check the
manufacturers recommendations before purchasingy-
our paint.
THINNING
Always rememberto disconnect from the
mains sup-ply before fi lling the paint contain-
er with sprayable material.
Most paints are supplied ready for brush application
and will need to be thinned before they are suitable to
be sprayed. Follow the manufacturers advice on thin-
ning the paint when used with a spray gun. The viscos-
ity cup will help you to determine the correct viscosity of
paint to be used. To determine the correct viscosity, fi ll
the cup to the brim with the paint. Measure the amount
of time it takes for the cup to empty back into the can.
The table below shows recommended times for differ-
ent types of material.

If the paint takes longer than the recommended time to
empty, then further thinning is required. Mix in a small
quantity of the appropriate thinner and use the viscos-

ity test until the correct thickness is achieved. Some
sprayable materials contain particles and lumps. These
materials should be strained before fi lling the paint con-
tainer.
SPRAYING C
Fill the paint container with the correctly thinned
and strained paint. Connect the spray gun to the
mains supply. Aim the spray gun at a piece of
scrap material and operate the trigger switch until
paint is spraying. Adjust the output control
until the required volume of paint is spraying.
SPRAYING TECHNIQUES
To obtain the best results, keep your spray gun level
and parallel to the surface at all times.
Keep the nozzle 25 - 30 cm from the surface and spray
evenly from side to side or up and down. Do not spray
at an angle as this will lead to paint runs on the surface.
Use smooth and even strokes. When spraying large
areas, use a criss-cross pattern as shown.
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.
