ABOUT THE SG85.
The SG85 is a highly versatile electric airless spray gun, it can be used with several different spray mediums including varnishes, wood preservatives, enamel paint, oil based paint and water based paints. Airless spraying reduces the mist associated with air spraying and also reduces paint loss. A number of applications can be performed including spraying fences, sheds, boats, furniture, radiators, models, louvre doors etc.
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.
IT CANNOT BE USED FOR EXTERIOR TEXTURED WALL PAINTS OR TEXTURED COATINGS. USE OF THESE
MATERIALS WILL CAUSE PREMATURE WEAR ON THE PISTON AND WILL VOID YOUR GUARANTEE. TO OBTAIN THE BEST RESULTS FROM YOUR SPRAY GUN PLEASE READ THE INSTRUCTIONS CAREFULLY BEFORE USE.
Your spray gun is supplied with the following items:
.
2 x 0.8mm and 1 x 0.6mm spray
nozzles.
.
Viscosity cup for thinning paint.
.
Flexible extension nozzle for overhead
painting.
.
Spare valve x 2.
.
Bottle of lubricating oil to lubricate the
piston after use.
.
1.5m (5’) suction tube, return cup and
fitting; for use with paint cans.
PREPARATION
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.
sg82 amend p8.qxd 19/01/00 12:35 Page 4
Page 5
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. 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 spraying.
IDEAL VISCOSITY 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 15-25secs Wood stains no dilution Latex Emulsions *10-20% dilution Smooth Masonry Paint (non grit)
*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.

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.
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 fil­ter 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 OVERFILL. Screw the spray gun on to the container tightly. Plug in the unit and before you start spraying the object, pull the trigger, aiming the gun at a piece of cardboard or newspaper until the paint comes out.
sg82 amend p8.qxd 19/01/00 12:35 Page 5
Page 6
Adjust the output control knob on the back of the gun to control the volume of paint that you wish to apply (fig 3). This will also affect the 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.
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.
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
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 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 4).
3. Do not tip the sprayer to more than 45oangle. Material could flow into the motor housing and damage the sprayer.

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 manufacturers 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.
4. When spraying large areas or objects, it is best to use a criss­cross pattern, either from left to right then up or down or vice-versa. This will ensure maximum coverage (fig 5).
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, continue and do not stop until the spray has gone past the opposite edge.
SPRAY NOZZLE SELECTION
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.
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.
USING THE FLEXIBLE EXTENSION NOZZLE
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 tilted at more than a 45ºangle to prevent a back leak, it is essential to use the flexible extension to paint ceilings (fig 6).
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.
3) Ensure the short atomiser valve is inserted into the flexible extension tube.
7
Fig 6
sg82 amend p8.qxd 19/01/00 12:35 Page 7
Page 8
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.
6) When finished using, clean all parts
and then re-assemble in the original configuration.
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.
Assembling the 1.5m (5’) Suction T ube:
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).
4. Insert 1.5m (5’) intake suction
tube into adapter fitting up to the stop. Insert other end of flexible tube
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.
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.
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. Observe the fluid level in the return cup, empty before it is completely full.

PRIMING THE SPRAYER
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.
WARNING- The filter must be completely submerged in the paint at all times. If not completely submerged and air is sucked into the system, the piston could seize. If the piston seizes, the sound the gun makes will change to a low hum and the gun will quickly become hot. Stop using immediately. Clean and lubricate gun throughly before re-using.
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.
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 OF 32oC MINIMUM. ENSURE ADEQUATE VENTILATION AND DO NOT SPRAY NEAR NAKED FLAMES.
Pour some more of the thinner that was previously used into the container and spray the gun until what is being sprayed becomes clear. Wipe the nozzle and paint filter then clear any remaining debris.Finally turn the gun upside down and apply a few drops of the lubricating oil to the piston (fig 8).

Momentarily trigger the spray gun to disperse the oil around the piston and cylinder.
LONG TERM CLEAN-UP
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:
1) Ensure the spray gun is unplugged.
2) Remove paint container and pull out the suction tube.
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.
10) Re-assemble in reverse order.
See fig 9.
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 bumpers. 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.
