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
volume of paint is spraying. Turn the output control
in a clockwise direction (B) to reduce the fl ow and
anti-clockwise (A) to increase the fl ow. Adjustment of
the output control will affect the spray pattern. A poor
spray pattern will concentrate the paint in the centre
of the spray and give a blotchy fi nish. A good spray
pattern will give even distribution of paint throughout
the pattern.
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.
