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

Water based paints 35-45secs

Oil Based paints 15-25secs

Enamel paints 15-25secs

Wood preservatives no dilution

Primers 20-30secs

Varnishes 20-25secs

Aluminium paints

Wood stains

Latex Emulsions

Smooth Masonry

Paint (non grit)

15-25secs

no dilution

*10-20% dilution

*5-10% dilution

• These paints cannot be measured in the viscosity cup. To spray them, remove the filter from the suction tube, thin according to manufacturer's recommendations and strain to remove any lumps or particles.

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^ ). 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 anticlockwise. 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 extension 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)

• Unscrew 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'

• Push the remote Pick Up Tube (2) firmly over the two spouts of the cylinder moulding.

• Fit 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.

• Immense 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).
• When 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 thoroughly 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 occurring and provide consistent 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)

• Disconnect the spray gun from the mains power.
• Remove paint container and pull out the suction tube.
• Unclip the filter from the suction tube.
• Unscrew the spray nozzle and remove the atomiser valve, making sure that the spring is not 'stretched' during removal.
• Unscrew the locking collar and remove cylinder housing from the motor housing, by pulling forward and down.
• Remove the piston and spring.
• Submerge all of the components into a cleaning fluid compatible with the material being sprayed.
  Clean all parts thoroughly.
• Lightly oil the piston and slide in and out of the cylinder to distribute the oil over the mating parts.
• Re-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.

A worn 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.
