INTRODUCTION
HVLP stands for High Volume, Low Pressure. This is a type of spraying that
allows you to spray extremely accurately but without all the overspray that occurs
with the high pressure tank type equipment. In fact, in some parts of the world
the high pressure systems are banned by law on environmental grounds and
HVLP type systems are the only alternative for professional type spraying. This
gun is extremely easy to use, very safe and reduces the amount of paint used .
PLEASE NOTE
We have done all we can to ensure that used correctly and according to these
instructions, this spray gun will give long and trouble free life. We accept no
responsibility for damage caused by the use of incorrect or unsuitable
substances, paints or fluids which have not been thinned correctly or are
unsuitable for the surfaces to which they are applied, health hazards arising from
lack of ventilation when working in confined spaces or failure of the equipment
due to inadequate cleaning of the components after use.
If in doubt, always test a small inconspicuous area first. Always read the paint
manufacturer’s instructions first.
Neither our guarantee nor the above statement affects your statutory rights.

IMPORTANT – SELECTING PAINT
This is a highly versatile spray gun that
can be used with several different spray
mediums including varnishes, wood
preservatives, enamels, oil and water
based paints and cellulose. However
some materials cannot be sprayed so
please check the manufacturer’s recommendation before buying the paint. If a
material refers to brush application only
then it cannot be sprayed.
THIS CANNOT BE USED FOR TEXTURED EXTERIOR WALLPAINTS OR
INTERIOR COATINGS. USE OF
THESE MATERIALS WILL CAUSE
PREMATURE WEAR, WHICH WILL
VOID THE GUARANTEE.
TO OBTAIN THE BEST RESULTS
FROM YOUR SPRAY GUN PLEASE
READ THE INSTRUCTIONS CAREFULLY BEFORE
USE.
PREPARATION
Preparation of the surface and thinning
of the paint 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, rust and grease. If necessary rub
down with sandpaper, or similar.
Masking of areas is important to ensure
you do not spray those areas you wish
to remain untouched.
THINNING
Your spray gun is supplied with a viscosity cup. Viscosity is a technical term
used to indicate if a product is very liquid or very thick. If liquid, the viscosity
is said to be low, while if very thick the
viscosity is said to be high.
Viscosity is measured in seconds. In
order to spray some materials they
need to be “thinned”.
Thinning is very important when spraying. Most paints etc are supplied ready
for brush application and may need to be
thinned (diluted) for spraying purposes.
Follow the manufacturer’s guide for thinning in conjunction with a spray gun. If in
doubt please contact the manufacturer’s
of the paint. The viscosity cup supplied
will help you determine the correct thickness of the paint. Paint is “thinned” by
adding the substance which the paint is
based upon. If a water based paint then
water is added, if oil based then white
spirit, if cellulose then a cellulose thinner
is added.
As some paints, wood preservatives
and other sprayable materials contain
particles that have differing qualities,
please ensure that when filling the paint
container of the spray gun, that the
paint is filtered through either a funnel
with a filter on it or through nylon tights
or stockings. This will ensure that no
large particles enter the paint container,
so preventing blockages and provide
you with trouble free spraying. Ensure
that a face mask, gloves and goggles
are worn at all times when spraying.
IDEAL VISCOCITY
Water based paints 45 - 60 seconds
Oil based paints 45 - 50 seconds
Wood preservatives No dilution
Primers 45 - 50 seconds
Varnishes No dilution
Aluminium paints No dilution
Wood stains No dilution
Cellulose Manufacturers ratio
This gun can be used having products
with a viscosity ranging from 10 to a
maximum of 60 seconds.

final.qxd 22/02/00 11:05 Page 4
Dip the viscosity cup into the material
and fill up. Time how long it takes for
the viscosity cup to empty (Fig 1).
Using the above chart (or manufacturer’s instructions) as a guide determine
if the material requires further thinning,
if so then thin accordingly.
OPERATION
Fill the paint container with the material
to be sprayed. DO NOT OVERFILL.
Screw the container onto the body tightly.
The spray gun is supplied with a hose.
This is designed to fit into the hose
supplied with the Combivac to give you
sufficient length of hose to be able to
spray most objects without limiting the
spraying action.
The Combivac hose needs to be fitted
to the “Blower” outlet (Fig.2) – this is
the outlet at the top of the machine.
Connect the additional hose, supplied
with the Spray Gun into the end of the
Combivac hose and the other end into
the back of the Spray Gun.
ALWAYS KEEP THE COMBIVAC UNIT
AS FAR AWAY FROM THE SPRAYING
AREA AS POSSIBLE TO PREVENT
PAINT CONTAMINATING THE
MOTOR.
MASK ANY AREA YOU DO NOT WISH
TO BE SPRAYED
Once you have set up ready to spray,
switch on the Combivac. No paint will
be sprayed from the gun until the trigger on the Spray Gun is pulled. Before
starting any work on spraying actual
objects we suggest you spend a small
amount of time practicing on cardboard
or newspaper until you have got used
to how the gun works.
Position the fluid tube in the paint container to provide the best angle to pick
up all the paint in the container
SPRAY PATTERNS
The gun has both adjustable volume
control and 3 different spray patterns –
Horizontal, Vertical and Round (Fig.3)
The horizontal and vertical are recommended for large surfaces. The round
spray is used for small objects or for
areas - such as corners – that are difficult to reach.
To adjust the spray pattern, loosen the
adjustment ring (9), adjust the position
of the nozzle (8) to obtain either a vertical, horizontal or round pattern then retighten the adjustment ring.

PAINT VOLUME
The volume of paint sprayed is easily
adjustable.(Fig.4)
Completely close adjustment screw (4)
by turning this clockwise as far as it will
go. Whilst pulling the trigger, begin turning the adjustment screw anti-clockwise
until the volume of paint you require is
obtained.
If the paint spray is too wide or contains
too much paint turn the adjustment
screw clockwise again. Once the correct spray pattern is obtained you are
able to commence spraying.
SPRAYING TECHNIQUE
1.To obtain the best results always keep
your spray gun level and spray equally from
side to side or up or down 25-30cm (10”-12”)
from the surface. Avoid spraying at an angle
as this will lead to runs on the surface (fig.5).
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.5).
3. Do not tip the sprayer to more than 45
o
angle.
HELPFUL HINTS
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
manufacturer’s instructions for drying times.
3. If spraying small areas or objects keep the
output setting low as this will avoid
excessive use of paints and will minimise
overspray.
Fig.5
Fig.4
Fig.6
final.qxd 22/02/00 11:05 Page 6
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. 6).
5. Avoid stopping and starting when spraying
as this can lead to too much or not enough
material on a surface.
6. To ensure edges are covered, commence
spraying just to the side of area being
sprayed
7. CLEAN SPRAYER AFTER EVERY USE
(SEE CLEANING INSTRUCTIONS)
CLEANING INSTRUCTIONS
THE SPRAY GUN MUST BE
THOROUGHLY CLEANED
IMMEDIATELY AFTER USE.
IF THE PAINT DRIES INSIDE THE
GUN, CLEANING WILL BECOME
MUCH MORE DIFFICULT AND
MAY RENDER THE GUN INOPERABLE. THIS IS NOT COVERED BY
GUARANTEE.
The spray gun is the same as a paintbrush, if it is not cleaned it will go hard
and can become useless. You must
therefore clean this out after use.
