INTRODUCTION
HVLP stands for High Volume, Low Pressure. This type of spraying technology allows you to spray extremely
accurately 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. The spray gun is extremely easy to use, very
safe and reduces the amount of paint used.
IMPORTANT SELECTING PAINT
This is a highly versatile spray kit 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 recommendation of the manufacturer before
buying the paint. If a material refers
to brush application only then it usually cannot be sprayed.
THIS UNIT CANNOT BE USED FOR TEXTURED PAINTS. USE OF THESE MATERIALS WILL CAUSE
PREMATURE WEAR, WHICH WILL VOID YOUR GUARANTEE.
TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY KIT 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 kit.
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 kit is supplied with a viscosity cup. Viscosity is a technical term used to indicate if a product is very
thin or very thick. If thin, 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” (diluted).
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 manufacturers guide for thinning in conjunction with a spray gun. If in doubt please contact the
manufacturers of the paint. The viscosity cup 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 providing you with trouble free spraying. Ensure that a face
mask, gloves and goggles are worn at all times when spraying.
IDEAL VISCOSITY
Water based paints and 45 - 60 seconds
emulsions
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 Manufacturer’s ratio
This spray gun can be used with products having a viscosity ranging from 10 to a
maximum of 60
seconds.
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 spray medium. Take care not to overfill.
Take the spray gun unit and with the clamp lever (22) turned fully anti-clockwise, locate the spray gun unit into
the paint container. Rotate the container until the 2 pins locate into the recesses in the yoke (23). Now turn the
clamp lever clockwise to secure the container to the lid. Do not over tighten.
Place the motor unit onto a clean floor space, free from any loose debris, liquids or dust sheets that could block
the motor inlet. Unwind the hose from the main housing and connect to the back of the gun. Uncoil the mains
cable from the base of the unit and plug in.
ALWAYS KEEP THE MOTOR UNIT AS FAR AWAY FROM THE SPRAYING AREA AS POSSIBLE TO
PREVENT PAINT CONTAMINATING THE MOTOR.
MASK ANY AREA YOU DO NOT WISH TO SPRAY.
Once you have set up ready to spray, switch on the unit. 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.
SPRAY PATTERNS
The gun has 3 different spray patterns – Horizontal, Vertical and Round (Fig.2).
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 change the spray pattern simply rotate the Air Cap (2) until
it clicks into the positions as shown in (Fig 2).
The overall size of the selected spray pattern can be varied by
turning the Air Cap Ring (1). When viewed from the front, rotate
it clockwise to increase the pattern size, or anti-clockwise to
reduce the pattern size.
PAINT VOLUME
The volume of paint sprayed is easily adjustable (Fig.3). Completely close adjustment
screw (12) 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 contains too much paint turn the adjustment screw clockwise to reduce
it. Once you have set the spray pattern & the paint volume, you are ready to begin
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 from the surface. Avoid spraying at an angle as this will lead to runs on the surface (Fig.4).
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 spray gun to more than 45˚angle (Fig.6).

Fig.6
NEEDLE & FLUID TIP SELECTION
Paints, varnishes, wood treatments etc, are manufactured using a variety of materials & have widely different
viscosities. You may find that the 2.0mm dia Fluid Tip & Needle supplied with this spray gun does not enable
you to spray your particular choice of finish exactly as you would like. In such cases a change of Fluid Tip &
Needle size will probably solve this problem.
In general, thicker, more viscose materials are best sprayed through a larger Fluid Tip to give best coverage.
Thinner, less viscose materials are best sprayed through a smaller Fluid Tip.
To allow for these variations Fluid Tip & needle sets are available, as optional extras, in 1.0mm dia, 1.5mm
dia & 2.5mm dia (See page 3).

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 adjusting screw 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. 7).
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 SPRAY GUN AFTER EVERY USE (SEE CLEANING INSTRUCTIONS).
CLEANING INSTRUCTIONS
THE SPRAY GUN SHOULD BE THOROUGHLY CLEANED & THE GLAND WASHERS LUBRICATED,
IMMEDIATELY AFTER EACH USE. IF THE PAINT DRIES INSIDE THE GUN CLEANING WILL BE MUCH
MORE DIFFICULT & MAY RENDER THE GUN INOPERABLE. THIS IS NOT COVERED BY THE
GUARANTEE.
Flush out the residue paint from the spray gun, as follows:
Remove the paint container (17) from the spray gun.
Pour any residual paint into its original container for future use.
Use a cloth soaked in thinners to wipe out excess paint from the container, the underside of the lid (20) &
the gasket (19).
Pour a small quantity of clean thinners into the container, re-fit the container to the spray gun and shake the
gun lightly.
Now spray all of the thinners through the gun.
Repeat this, each time using clean thinners, until there is no trace of paint in the thinners being sprayed.
To thoroughly clean the remainder of the spray gun, remove all working parts as per the exploded spare parts
drawing on p.3 as follows.
Loosen and remove Air Cap Ring (1), Air Cap (2) and Air Distributor Plate & Spring (3).
Now unscrew the Adjusting Screw (12) and pull out the Needle (9) and Needle Spring (11).
Use the supplied spanner, to remove the Fluid Tip (4) and Fluid Tip Seal (5).
All of the components above can be immersed in thinners and cleaned using the cleaning kit supplied with this
product. After cleaning your spray gun and before fitting the needle, dip the tip into some vaseline which will
lubricate the gland washers as the needle is inserted.
The external surfaces of the spray gun can be wiped clean with a cloth soaked in thinners.

NEVER DISPOSE OF PAINTS OR SOLVENT INTO DRAINS. CONTACT YOUR LOCAL COUNCIL TO
ARRANGE COLLECTION OR FOR DETAILS OF NEAREST REGISTERED DISPOSAL SITE.
PERIODIC MAINTENANCE
Gland Washers (16) prevent leakage of air past the needle. This leakage reduces the performance of the spray
gun and must, therefore, be kept to a minimum. After a period of use the Gland Washers will wear. This is
normal and can be compensated by gradual adjustment of the Gland Nut (15).
Periodically check to ensure the Gland Nut is not loose. DO NOT OVER-TIGHTEN as this will increase wear
of the washers. When necessary just tighten the nut lightly using the special spanner provided.
By tightening this nut, the inside diameter of Gland Washers reduce thereby closing any small gap that may
have occurred between the Needle & Gland Washers, therefore, eliminating excess leakage.

TURBINE UNIT
The turbine unit only requires minimal maintenance
Ensure its filter element is kept clean at all times.
This is the filter underneath the main body of the Motor Unit (28). Disconnect the unit from the mains,
turn on side and remove foam material. This can be washed out if necessary and replaced when dry. From
time to time this filter will need replacing (part no.L0058).
The turbine bearings are sealed and lubricated for life. There is no maintenance or adjustment required.
Clean the turbine and hose unit with a damp cloth after use.
The hose is stored by coiling it between the motor housing and hose cover.
The mains lead is stored by wrapping around the base of the unit and locating the plug in the space at the
back of the unit.
TROUBLE SHOOTING
MAINS CONNECTION
This unit is a Class II appliance which means it is double insulated for your protection, no earthing wire is
necessary.
If the supply cord is damaged, it must be replaced by Earlex Ltd or our appointed agents.
Your unit has been supplied with a mains lead with a fitted plug. This is identified by the fuse holder in the base
of the plug. Please read the following safety instructions before use.
1. If the fitted plug is cut off from the mains lead then the plug must be disposed of safely. NEVER under any
circumstances insert such a plug into a 13 amp socket.
2. NEVER under any circumstances use the appliance or mains lead without the fuse cover fitted.
This is the little cover fixed into the base of the plug to hold the fuse in place.
3. If you lose the fuse cover then please contact any electrical dealer for a replacement or ring our helpline.
4. A replacement fuse must be rated at 5 amp. These must be manufactured and approved to BS 1362.
5. IF IN ANY DOUBT CONTACT AN ELECTRICIAN.
If you need to fit a plug to the mains lead, this should be fitted in accordance with the wiring instructions below,
and will need to be used with a 5 amp fuse. If in doubt consult an electrician.
If you are using an extension lead it must be rated at a minimum of 6 amps and fully unwound. Do not operate
with a lead rated at less than 6 amps as this will cause premature failure of the motor which is not covered by
the guarantee.
As the colours of the wires in the mains lead of the application may not correspond with
the coloured markings identifying the terminals in your plug, proceed as follows:
The wire which is coloured blue must be connected to the terminal which is marked
with the letter N or coloured black.
The wire which is coloured brown must be connected to the terminal which is marked
with the letter L or coloured red.
