PREPARATION
IMPORTANT- SELECTING PAINT
Although a large number of paints
and materials can be sprayed,
some cannot. Please check
manufacturers recommendation
before purchasing paint.
CUPRINOL® This company’s
products clearly show which can be
sprayed and which are brush only.
If the can gives details of ‘Airless
Spraying’ it can be sprayed. If it
refers to brush application only it
cannot be sprayed.
Surface preparation and paint
thinning are the two most important
areas to be concerned with to
obtain the best results from your
spray gun.
Ensure all surfaces are free from
dust, dirt and grease.
Masking is important to ensure you
do not spray those areas you wish
to remain untouched.
Ensure paint is thoroughly mixed.
THINNING
Thinning is particularly important
when spraying. Most paints are
supplied ready for brush application
and need to be sufficiently diluted
for spraying purposes.
IT CANNOT BE USED FOR
EXTERIOR TEXTURED WALL
PAINTS OR TEXTURED
COATINGS. USE OF THESE

* These paints cannot be measured in
the viscosity cup. To spray them,
remove the filter from the suction tube,
thin according to manufacturer’s recom-
mendations and strain to remove any
lumps or particles.
Fig 1
Follow the manufacturers guide for
thinning inconjunction with a spray
gun. If in doubt please consult the
manufacturer of the paint. The
viscosity cup supplied will help you
determine the correct thickness of
the paint.
Fig 2
Fig 3
Dip the viscosity cup into the
material and fill up. Time how long it
takes the viscosity cup to empty (fig
1). Using the above chart as a
guide to determine if the material
requires further thinning, thin
accordingly.
As some paints, wood
preservatives and other sprayable
materials contain particles and have
different qualities, please ensure
that when filling the paint container
on your SG85, the paint is filtered
through either a funnel with a filter
on it, or through nylon tights or
stockings. This will ensure no large
particles enter the paint container,
so preventing blockages and
providing you with trouble free
spraying. Ensure that a face mask,
gloves, goggles and ear protectors
are worn at all times when
OPERATION
Turn the gun upside down and
place a few drops of lubricating oil
in both the apertures on the
underside of the gun (see fig 2).
Momentarily trigger the spray gun
to disperse the oil around the piston
and cylinder, then firmly push the fil-
ter suction tube into the tapered
hole of the raised boss.
Fill the container with the paint,
when filling the paint container, filter
the paint through a piece of nylon
stocking or a funnel which
incorporates a filter to remove any
lumps or particles. DO NOT
spraying.

Adjust the output control knob on
the back of the gun to control the
volume of paint that you wish to
up or down 25-30cm (10”-12”) from
the surface. Avoid spraying at an
angle as this will lead to runs on the
apply (fig 3). This will also affect the surface (fig 4).
spray pattern. A poor spray pattern
will concentrate the paint in the
centre of the spray and give a
blotchy finish. A good spray pattern
is achieved when there is an even
amount of material in a fine spray
throughout the pattern.
2. Let your arm control the left to
right movement rather than your
wrist as this will aid even paint
distribution over the whole area
(fig 4).
3. Do not tip the sprayer to more
than 45o angle. Material could flow
into the motor housing and damage
the sprayer.
USING THE OUTPUT CONTROL
KNOB
Turning the output control knob
clockwise reduces the flow of
material whilst turning it
anti-clockwise increases the flow.
To adjust the pattern undertake the
following:
1. Turn the knob anti-clockwise to
the maximum position.
2. Pull the trigger and test the
pattern on a piece of cardboard
or newspaper.
3. Turn the output control knob
clockwise until the spray pattern
is correct.
If you have undertaken the above
and you still cannot obtain a good
spray pattern then the material
being sprayed probably requires
further thinning.
Fig 4
MASK ANY AREAS YOU DO NOT
WISH TO BE SPRAYED.
SPRAYING TECHNIQUE
1.To obtain the best results always
keep your spray gun level and
spray equally from side to side or

HELPFUL HINTS
3) If you start spraying and find that
the spray pattern is small and
splattery and adjusting the output
control knob does not solve the
problem then you need to try the
larger nozzle before further thinning
the material.
1. Evenly control the speed of
movement of the spray gun. A fast
speed will give a thin coat and a
slow speed will give a heavy coat.
2. Only apply one coat at a time. If
a further coat is required follow the
paint manufacturers instructions for
drying times.
USING THE FLEXIBLE
EXTENSION NOZZLE
3. If spraying small areas or objects
keep the output setting low as this
will avoid excessive use of paints
and will minimise overspray.
4. When spraying large areas or
objects, it is best to use a criss-
cross pattern, either from left to
right then up or down or vice-versa.
This will ensure maximum coverage
(fig 5).
The flexible
extension nozzle
can be bent at any
angle to make the
painting of ceilings
and floors much
easier. As the sprayer must not be
Fig 6
º
tilted at more than a 45 angle to
prevent a back leak, it is essential
to use the flexible extension to paint
ceilings (fig 6).
5. Avoid stopping and starting when
spraying as this can lead to too
much or not enough material on a
surface.
To use this, operate as follows:
1) Unscrew the spray gun nozzle by
turning it anti-clockwise. Be sure to
leave the valve in place but check
for wear.
2) Screw the end of the extension
tube with the plastic thread onto the
spray gun.
6. To ensure edges are covered,
commence spraying just to the side
of area being sprayed, continue and
do not stop until the spray has gone
past the opposite edge.
SPRAY NOZZLE SELECTION
3) Ensure the short atomiser valve
is inserted into the flexible
extension tube.
Two nozzle sizes are supplied with
the gun, these should be used as
follows:
1) 0.6mm - This size works best for
oil-based materials, stains, sealers,
lacquers, water-proofers and
enamels for small application areas.
2) 0.8mm - This is a general
purpose nozzle that works best for
materials such as emulsions, latex
and thicker type paints.

4) Screw the spray nozzle onto the end
of the flexible extension.
5) Bend the flexible extension to the
required shape. Once bent do not
straighten.
over suction tube filter moulding, ensure
this fits tightly to prevent air leaks,
immerse filter end of suction tube into
paint can and secure tube to can using
the retainer clamp.
6) When finished using, clean all parts
and then re-assemble in the original
configuration.
5. To reduce the time the sprayer runs
without paint, hold the sprayer below the
paint level when priming the sprayer, this
speeds up the time the paint takes to
draw through the tube. The paint may
need additional thinning if you still
experience difficulty priming the sprayer.
The paint must be stirred fully before
use.
CLEAN AFTER EVERY USE
(SEE CLEANING INSTRUCTIONS)
HOW TO USE THE 1.5m (5’)
SUCTION TUBE
For larger painting applications, using the
1.5m (5’) suction tube enables you to
draw paint directly out of a large can
instead of using the paint container, thus
saving considerable time and making
painting an even easier job, since you
are operating the sprayer without a
loaded paint container.
6. When using the spray gun with the
1.5 suction tube only use the gun in
normal upright position, support or hang
the gun in an upright position during
breaks of use.
If the gun is not kept in the normal
upright position after use, remove the
cup and drain the fluids before placing
down on it’s side.
Assembling the 1.5m (5’) Suction
Tube:
Observe the fluid level in the return cup,
empty before it is completely full.
1. Remove the paint container and the
intake tube from the paint sprayer.
2. Insert the adapter fitting through the
hole in the return cup into the paint
intake port on the sprayer-ensure this is
firmly pushed in. (Same position as
where the section tube was removed
from).
3. Locate the return cup within the
recess where the paint container was
located. Slip the retainer nut over cup
and screw into place firmly. (The return
cup is necessary to catch any paint that
is returned through the overflow bypass
opening below the paint pump).

PRIMING THE SPRAYER
CLEANING
Run solvent through the tube until it
is clean. Then disassemble the
fittings at both ends before any
remaining paint dries up, thoroughly
clean the adaptor fitting, intake tube
and filter. Also remove the return
cup and clean with an appropriate
solvent.
If you are using the suction tube,
you will need to prime the sprayer
by removing air from the system.
To prime:
1. Turn the flow knob fully
counterclockwise to maximum.
2. Make certain the sprayer is
plugged in.
3. Hold the sprayer below the level
of paint. This will speed the priming.
4. Squeeze the trigger and hold
until all air is out of the system and
material is flowing freely out of the
sprayer tip. This should take about
two minutes.
CLEANING INSTRUCTIONS
After every use it is essential that
you clean the gun thoroughly. This
will prevent any blockages
occuring and provide constant
performance when you next come
to use it.
When you have finished spraying,
empty any remaining material out of
the paint container.
Rinse the spray gun container with
the thinner that was used and spray
through the gun onto cardboard or
newspaper.
REMEMBER-USE SUITABLE
THINNERS WITH A FLASH POINT

Pour some more of the thinner that
was previously used into the
container and spray the gun until

LONG TERM CLEAN-UP
Fig 9
If the spray gun is being stored for
a period of time the following
should also be undertaken in
addition to the above cleaning
instructions:
MAINTENANCE AND REPAIR
Please be aware that certain parts
of this spray gun will wear, requiring
replacement and that these parts
are not covered by guarantee.
These parts include the valve,
spray nozzle, piston and spring.
The wear on these parts depends
on the abrasiveness of the
materials being sprayed. More
abrasive materials such as latex
paint (emulsions) will cause these
parts to wear much faster. You
would normally expect to replace an
atomiser valve after spraying
between 25-45 litres of latex.
If you check the face of a new valve
you will see the size of the 3 holes
and the smoothness of the
1) Ensure the spray gun is
unplugged.
2) Remove paint container and pull
out the suction tube.
3) Unscrew the 4 mounting screws
on the underside of the cylinder
housing.
4) Remove container cover and
cylinder housing from the motor
housing.
5) Remove the piston and spring,
thoroughly clean with the
appropriate thinner.
6) Remove the spray nozzle by
turning anti-clockwise.
7) Pull out the valve, making sure
that this is not ‘stretched’ during
removal or lost.
8) Clean all parts thoroughly.
9) Lubricate with oil.

Worn valves will have larger holes
and scratches on the surface. This
will cause a poor spray pattern and
will require replacing. Replacement
valves are available from the Earlex
Service Department.
10) Re-assemble in reverse order.
