1. SAFETY
WARNING! Disconnect the spray gun from the air supply before changing accessories, servicing or performing any maintenance.
9 Familiarise yourself with this products application and limitations, as well as the specific potential hazards peculiar to the spray gun.
Paint cup remains pressurised after gun is disconnected from air line.
9 DO NOT pull the trigger, but release the pressure by gently opening cup.
9 Maintain the spray gun in good condition (use an authorised service agent). Replace or repair damaged parts.
9 Use recommended parts only. Non authorised parts may be dangerous and will invalidate the warranty.
9 Locate the spray gun in an adequate working area for its function, keep area clean and tidy and free from unrelated materials, and
ensure there is adequate ventilation and lighting.
9 Keep the spray gun clean for best and safest performance.
9 Ensure the air system is suitable to the spray gun air consumption, (see specifications).
9 Remove ill fitting clothing. Remove ties, watches, rings, and other loose jewellery, and tie back long hair.
9 Keep children and unauthorised persons away from the working area.
8 DO NOT point spray gun at yourself, at other persons or animals.
8 DO NOT carry the by the air hose, or pull the hose from the air supply.
8 DO NOT use the spray gun for any purpose other than for which it is designed.
8 DO NOT allow untrained persons to operate the spray gun.
8 DO NOT get the spray gun wet or use in damp or wet locations or areas where there is condensation.
8 DO NOT operate gun if any parts are missing or damaged as this may cause failure or personal injury.
8 DO NOT direct air from the air hose at yourself or others.
9 Avoid unintentional operation. When not in use switch the spray gun off, and disconnect from the air supply.

5. ASSEMBLY
5.1. Empty contents from the product carton on to a tray or bench. In the unlikely event of missing or damaged parts, inform your Sealey
stockist immediately.
5.2. The spray gun has been treated with an anti corrosive agent at the factory and MUST be flushed out thoroughly before use.
5.3. Ensure the strainer, item 4 fig.1, is inserted into the gun port with the stem outermost for easy removal.
5.4. Fit the pot and selected spray head, hand tight only.
6. AIR SUPPLY
6.1. Recommended hook-up g.2
6.1.1. Ensure spray gun air valve (or trigger) is in the off position before connecting to the air supply.
6.1.2. You will require an air pressure of 43psi, and an air ow according to specication.
WARNING! Ensure the air supply is clean and does not exceed 43psi while operating the spray gun. Too high an air pressure and/or
unclean air will shorten the product life due to excessive wear, and may be dangerous causing damage and/or personal injury.
6.1.3. Drain the air tank daily. Water in the air line will ruin the paint nish and damage the spray gun.
6.1.4. Clean air inlet lter weekly.
6.1.5. Line pressure should be increased to compensate for unusually long air hoses (over 8 metres). The minimum hose diameter
should be 1/4” I.D. and ttings must have the same inside dimensions.
6.1.6. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
6.2. Couplings
Vibration may cause failure if a quick change coupling is connected directly to the spray gun. To overcome this, connect
a leader hose to the spray gun. A quick change coupling may then be used to connect the leader hose to the air line recoil hose
(g.2 and 3).

7. OPERATION
7.1. For best results, the gun should be held perpendicular to the surface being sprayed and moved parallel to it. Start the stroke before
squeezing the trigger and release the trigger before nishing the stroke. This will enable accurate control of the gun and material
(g.3B).
7.2. Spray from a distance of about 6 to 10 inches (150 to 250mm) depending on the material and the atomizing pressure. The material
deposited should always be even and wet. Each stroke must overlap the preceding stroke to obtain a uniform nish. To reduce
over-spray and obtain maximum efciency, spray with the lowest possible atomizing air pressure.
7.3. Controlling the fan spray and the uid.
a) Use the needle (paint) adjustment knob (g.4.2) to adjust the amount of paint ow.
b) The atomizing air ow is controlled by the control knob (g.4.1).
c) The volume of air input is controlled by the adjustment knob (g.4.3).
d) As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased area.
e) Turn the air nozzle (g.4.4) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (g.4.5). The spray
pattern of the gun is variable from round to at with all patterns in between. In normal operation, the wings on the nozzle are horizontal
(g.5). This provides a vertical fan-shaped pattern which gives maximum, uniform and even coverage when moving the gun back and
forth, parallel to the work surface (g.6).

8. CLEANING/MAINTENANCE
FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE SPRAY GUN IS CORRECTLY CLEANED AFTER
EACH USE. Disconnect from the air supply before attempting any cleaning or maintenance.
8.1. Cleaning the gun
8.1.1. Flush the gun through with clean solvent.
8.1.2. Use a bristle brush and solvent to wash off accumulated paint.
8.1.3. Clean the air nozzle using a brush. Blow clean with air. Handle all nozzles carefully and do not make any alterations in the gun.
8.1.4. Wipe the outside of the gun with a dampened solvent rag.
8.1.5. If there is a need to probe the holes in the nozzles, ensure a tool that is softer than brass is utilised, under no circumstances use a
metal tool, as the slightest amount of damage will adversely affect the spray pattern.
8.1.6. Adjust the uid needle valve so that when the gun is triggered, air ow occurs before uid ow.
8.2. Maintenance
8.2.1. Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check
that it is the correct part, or unscrew it, realign and retry. DO NOT use excessive force when re-assembling.
8.2.2. When changing the nozzle size, ensure the complete nozzle set is tted. This consists of air cap, uid nozzle and paint needle.
Insert the uid nozzle before paint needle.
9. TROUBLESHOOTING
A faulty spray is usually caused by improper cleaning or dried material around the uid nozzle tip or in the air nozzle. If cleaning is required,
remove these parts and soak them in solvent. This will soften the dried material which can then be removed with a brush or a cloth.
These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or uid nozzle are damaged,
they must be replaced before a perfect spray can be obtained.
Problem Possible Cause Solution
Dried material in a side port restricts passage of air.
Greater flow of air from the clean side port forces a
fan pattern in the direction of the clogged side.
Dried material around the outside of the fluid nozzle
tip restricts the passage of atomizing air at one point
through the centre opening of the air nozzle and
results in the pattern shown. This pattern can also be
caused by a loose air nozzle.
Material too thin or atomization air pressure too high. Regulate material viscosity or reduce air
Dissolve material in the side ports with solvent,
then blow the gun clean. Do not poke into the
nozzles with metal instruments.
Remove the air nozzle and wipe off fluid tip using
a rag dampened with solvent. Tighten the air
nozzle.
pressure.
Not enough paint in bottle.
Nozzle set / seating dirty, damaged or loosely
installed.
Refill bottle. Remove the fluid nozzle, clean the
back of the nozzle and the nozzle seat using a
cloth dampened with thinner. Refit the nozzle and
secure it tightly against the body.
If necessary replace nozzle set.
Paint spray ‘utters’
Material bubbles or “boils” in paint cup. Atomised air flowing through the paint channel to the
bottle. The paint nozzle is not sufficiently tight.
Air nozzle is not completely screwed on.
Tighten, clean or replace parts accordingly.
