TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY GUN READ THESE
INSTRUCTIONS CAREFULLY BEFORE USE.
ABOUT THE SPRAY GUN
The Spray Gun is a highly versatile electric airless spray gun. It can be used to spray many different
materials including varnishes, wood preservatives, enamel paints, oil based paints & water based
paints.
Airless spraying reduces the mist associated with air spraying & reduces paint loss.
The spray gun can be used for a variety of applications including, fences, sheds, boats, furniture,
radiators, models & louvre doors.
IMPORTANT - SELECTING THE PAINT
Many paints & other materials can be sprayed but some cannot. Always check the manufacturer’s
recommendations before using products with your spray gun.
THE SPRAY GUN MUST NOT BE USED FOR SPRAYING EXTERIOR TEXTURED WALL PAINTS
OR TEXTURED COATINGS. USING THESE MATERIALS WILL CAUSE PREMATURE WEAR ON
THE PISTON & WILL INVALIDATE YOUR GUARANTEE.
PREPARING THE PAINT (OR OTHER SPRAY MEDIUM)
It is most important to follow the paint manufacturer’s recommendations for thinning. Most paints are
supplied ready for brush application & must be diluted for use with the spray gun. If you are in any
doubt about how much to thin the paint, consult the paint manufacturer.
The viscosity cup supplied with your spray gun & the viscosity guide below, can be used to help you
determine the correct thickness of the paint.
The paint, or paint & thinners mixture, must be thoroughly stirred. We do not recommend the use of an
electric stirrer as this can increase the volume of air in the paint, which will reduce the effectiveness of
the spray gun.

VISCOSITY GUIDE

USING THE VISCOSITY CUP
Dip the viscosity cup into the paint (or other medium) to fill it.
Time how long the paint takes to empty from the cup (see fig.1) & refer to the viscosity guide on page
4 to compare the time. Thin the paint further until the recommended time is achieved.
PREPARING & USING YOUR SPRAY GUN
SAFETY WARNING!
DO NOT SPRAY FLAMMABLE MATERIALS (FLASH POINT < 21˚C). ALWAYS
SPRAY IN A WELL VENTILATED AREA. NEVER SPRAY NEAR NAKED
FLAMES.
ALWAYS WEAR PROTECTIVE FACE MASK, GOGGLES, GLOVES & EAR PROTECTORS WHEN
USING YOUR SPRAYGUN.
MASK THE AREAS OF THE ITEM THAT YOU DO NOT WANT TO SPRAY & PROTECT ANY
ADJACENT AREAS THAT COULD BE AFFECTED BY
OVERSPRAY.
Before fitting the paint container, turn the spray gun upside down &
put a few drops of lubricating oil down the inlet and outlet spouts.
(see fig.2)
Plug the spray gun into a power socket & run the motor for one or
two seconds to distribute the oil around the cylinder & piston.
Disconnect the power & push the Suction Tube & Filter firmly into
the inlet spout, which is the longer of the two spouts.
Fill the container with the prepared paint or other medium, which as a precaution should be filtered
through a suitable funnel that has a filter. As an alternative to a filter the paint can be poured through
a nylon stocking or tights. This should ensure there is no contamination of the paint that could block or
damage the spray gun. DO NOT FILL THE CONTAINER BEYOND THE MAXIMUM LEVEL
INDICATED.
Screw the spray gun tightly onto the filled container. Plug the spray gun into a power socket and it is
now ready to be set up.

SETTING UP THE SPRAY GUN FOR OPTIMUM
PERFORMANCE
When setting up the spray gun we recommend that you spray the paint
onto some scrap material, newspaper or cardboard. Purge the air from
the spray gun by running it for a few seconds until the paint comes out of
the gun.
The volume of paint & the spray pattern is controlled using the Output
Control Knob, (see fig. 3) Turn the knob anti-clockwise to increase the
volume of paint sprayed & clockwise to decrease the amount of paint
sprayed.
A good spray pattern is achieved when there is an even amount of paint
in a fine spray throughout the pattern. A poor spray pattern will
concentrate the paint in the centre of the spray & give a blotchy finish.
To get the best spray performance, turn the Output Control Knob fully anti-
clockwise. Aim the gun at a piece of cardboard, or similar waste material,
& press the switch to start the spray gun. With the spray gun running, turn
the Output Control Knob clockwise until the best spray pattern is achieved.
If you are unable to achieve an even, fine spray you will probably need to
thin the paint further. Follow the thinning procedure as described under
“Preparing the Paint”.

SPRAYING TECHNIQUE
To obtain best results keep the spray gun level & square on to the surface
being sprayed. The gun works best if the nozzle is kept about 25 – 30
cms (10” – 12”) from the surface being sprayed. (See fig. 4) This will result
in consistent, even coverage.
To avoid overlap of the paint & therefore uneven coverage, we
recommend that the spray gun be momentarily turned off whenever you
change direction.
Move the spray gun at an even speed. A fast speed will give a thin coat &
a slow speed will give a thicker coat. Never tilt the spray gun more than
45˚ as this could result in paint getting in to the motor & causing serious
damage.
HELPFUL HINTS
1) Only apply one coat at a time. If more than one coat is required follow
the paint manufacturers instructions for drying times.
2) If spraying small objects keep the output setting low as this will avoid
excessive use of paint & will minimise overspray.
3) When spraying large areas or objects use a criss-cross pattern either
left to right then up & down or vice-versa. Remember to momentarily
stop spraying as you change direction. This will ensure maximum,
even coverage. (See fig. 5)
4) Do not stop & start spraying while moving the gun in one continuous
direction.
5) To ensure edges are covered begin spraying just outside the area
being sprayed & do not stop until you have just passed the opposite
edge.

SPRAY NOZZLE SELECTION
The ASG100 spray gun is supplied with 0.6mm and 1.0mm nozzles, the ASG120 spray gun is also
supplied with a 0.8mm nozzle, 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.
3) 1.0mm - This nozzle is suitable for spraying woodcare treatments.
If when spraying you find that the spray pattern is small and splattery, and adjusting the output control
knob does not solve the problem, try a different nozzle size before further thinning the material.
USING THE FLEXIBLE EXTENSION TUBE.
Using the Flexible Extension Tube makes the painting of ceilings, floors & all
horizontal surfaces much easier. When fitted, the Flexible Extension Tube is bent
to avoid tilting the spray gun. Tilting the spray gun excessively can cause paint to
leak into the motor, causing serious damage.
TO FIT THE FLEXIBLE EXTENSION TUBE (see fig.6)
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 internal thread, tightly onto the spray gun. Leaks may
occur if the flexible extension is loose or if excessive force is used to fit it. e.g. using pliers.
3) Fit a swirl head into the end of the flexible extension tube with the external thread.
4) Screw a nozzle onto the end of the flexible extension tube.
5) Bend the flexible extension to the required angle (45˚ maximum). Do not bend the extention tube
more times than necessary, as repeated bending can cause premature failure.

REMOTE PICK UP SYSTEM - (ASG120 only)
For larger painting tasks, use the Remote Pick Up System. This
enables you to draw paint directly out of a large can instead of using
the paint container supplied with the spray gun, thereby saving
considerable time and making painting an even easier job. When using
the remote pick up system secure the Remote Pick Up Tube to the can
using the Remote Pick Up Clip provided. If working from a ladder, the
can may be carefully hung from a rung on the ladder using a wire hook.
We recommend a maximum continuous spray time of 30 mins, with a
minimum break of 20 mins before spraying again to avoid fatigue.
Assembling the Remote Pick Up System (see fig.7)
lUnscrew and remove the paint container and remove the Suction
Tube and Filter from the inlet spout. If the spray gun is being used
for the first time, lubricate the piston and cylinder before continuing.
See ‘Preparing and Using your Spray Gun’
lPush the remote Pick Up Tube (2) firmly over the two spouts of the
cylinder moulding.
lFit the Suction Tube and Filter (3) securely to the same side of the Pick Up Tube that is connected
to the inlet spout of the cylinder moulding.
lImmerse the Suction Tube and Filter into the can of paint and secure the Pick Up Tube to the can
using the Remote Pick Up Tube Clip (1).
lWhen using the spray gun with the remote pick up system, only use the gun in the normal upright
position, to allow the residue paint to drain away down the Pick Up Tube.
Priming the Spray Gun
When using the remote pick up system you must remove all the
air by priming the system as follows:-
1. Turn the output control knob fully anticlockwise to the
maximum position.
2. Make certain the spray gun is plugged in.
3. Hold the spray gun below the level of paint to speed the
priming.
4. Aim the spray gun at a piece of cardboard or old newspaper,
squeeze the trigger and hold until all air is out of the system
and material is flowing freely from the nozzle. This should
take about two minutes.
WARNING- When using the Remote Pick Up system the
filter, of the Suction Tube and Filter, must be completely
submerged in the paint at all times. If not completely
submerged, air will be sucked into the system and the
piston may seize. If this happens, the sound of the gun will
change to a low hum and it will quickly become hot. Stop
using immediately. Allow the gun to cool, then clean and
lubricate the gun throughly before re-using.

CLEANING THE REMOTE PICK UP COMPONENTS
Run an appropriate thinners through the tube until it is clean. Disassemble the fittings at both ends
before any remaining paint dries, and thoroughly clean the remote pick up tube, suction tube and filter.
GENERAL CLEANING INSTRUCTIONS
After every use it is essential that you clean the spray gun thoroughly. This will prevent any blockages
occuring and provide consistant performance when you next come to use it.
When you have finished spraying, empty any remaining material out of the paint container and clean it
thoroughly using the thinners used for the last job.
Rinse the spray gun container with the thinners used for the last job and spray through the gun onto
cardboard or newspaper, and follow the instructions below.
REMEMBER - DO NOT USE FLAMMABLE THINNERS
(except white spirit & turpentine substitute)
lDisconnect the spray gun from the mains power.
lRemove paint container and pull out the suction tube.
lUnclip the filter from the suction tube.
lUnscrew the spray nozzle and remove the atomiser valve, making sure that
the spring is not ‘stretched’ during removal.
lUnscrew the locking collar and remove cylinder housing from the motor housing, by pulling
forward and down.
lRemove the piston and spring.
lSubmerge all of the components into a cleaning fluid compatible with the material being sprayed.
lClean all parts thoroughly.
lLightly oil the piston and slide in and out of the cylinder to distribute the oil over the mating parts.
lRe-assembly is the reverse of the above.
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. The 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.
Aworn valve will cause a poor spray pattern and will require replacing. Replacement valves are
available from the Earlex Service Department.
You will need to check the spray nozzles, piston and spring from time to time to check for wear.
Replace if necessary.
NEVER DISPOSE OF PAINTS OR SOLVENTS INTO DRAINS. CONTACT
YOUR LOCAL COUNCIL TO ARRANGE COLLECTION.
