MODEL No: S701G
Thank you for purchasing a Sealey product. Manufactured to a high standard this product will, if used according to these instructions and
properly maintained, give you years of trouble free performance.
2. INTRODUCTION & SPECIFICATIONS
IMPORTANT: PLEASE READ THESE INSTRUCTIONS CAREFULLY. NOTE THE SAFE OPERATIONAL REQUIREMENTS,
WARNINGS AND CAUTIONS. USE THE PRODUCT CORRECTLY AND WITH CARE FOR THE PURPOSE FOR WHICH IT IS
INTENDED. FAILURE TO DO SO MAY CAUSE DAMAGE AND/OR PERSONAL INJURY, AND WILL INVALIDATE THE
WARRANTY. PLEASE KEEP INSTRUCTIONS SAFE FOR FUTURE USE.
1. SAFETY INSTRUCTIONS
3Familiarise yourself with this products application and limitations, as well as the specific potential hazards peculiar to the spray gun.
pWARNING! Disconnect the spray gun from the air supply before changing accessories, servicing or performing any maintenance.
3Maintain the spray gun in good condition (use an authorised service agent).
3Replace or repair damaged parts. Use recommended parts only. Unauthorised parts may be dangerous and will invalidate the warranty.
3Locate the spray gun in a suitable work area, keep area clean and tidy and free from unrelated materials, and ensure there is
adequate ventilation and lighting.
3Keep the spray gun clean for best and safest performance.
3Ensure the air system can supply sufficient air flow for the spray gun, (see specifications).
3Wear approved respiratory protection and safety eye goggles.
3Remove ill fitting clothing. Remove ties, watches, rings, and other loose jewellery, and tie back long hair.
3Keep children and unauthorised persons away from the working area.
3When not in use ensure the air supply is turned off.
3Avoid unintentional operation.
7DO NOT point spray gun at yourself, at other persons or animals.
7DO NOT carry the by the air hose, or yank the hose from the air supply.
7DO NOT use the spray gun for any purpose other than for which it is designed.
7DO NOT allow untrained persons to operate the spray gun.
7DO NOT get the spray gun wet or use in damp or wet locations or areas where there is condensation.
7DO NOT operate gun if any parts are missing or damaged as this may cause failure and/or personal injury.
7DO NOT direct air from the air hose at yourself or others.
3When not in use switch the spray gun off, and disconnect from the air supply.
3. AIR SUPPLY CONNECTION
fig 1
3.1. Air Supply
Recommended hook-up procedure is shown in fig 1.
3.1.1. Ensure spray gun air valve (or trigger) is in the off position before connecting to the air supply.
3.1.2. You will require an air pressure of 50psi, and an air flow according to specification.
3.1.3. pWARNING! Ensure the air supply is clean and does not exceed 50psi 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.
3.1.4. Drain the air tank daily. Water in the air line will ruin the paint finish and damage the spray gun.
3.1.5. Clean air inlet filter weekly.
3.1.6. 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 fittings must have the same inside dimensions.
3.1.7. Keep hose away from heat, oil and sharp edges. Check hose for wear, and make certain that all connections are secure.
3.2. 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. See fig 1 & 2.

FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE GUN IS CORRECTLY CLEANED AFTER EACH USE.
Disconnect from the air supply before attempting any cleaning or maintenance.
5.1. Cleaning the gun
5.1.1. Immerse the front end of the gun only in solvent. The solvent should just cover the
fluid connection. fig 7.
5.1.2. Use a bristle brush and solvent to wash off accumulated paint.
5.1.3. Do not immerse the entire gun in solvent as this will cause lubricants on the rubber
seals to dissolve. Dirty solvent may also clog narrow passages in the gun.
5.1.4. Flush the gun through with clean solvent.
5.1.5. Wipe the outside of the gun with a dampened solvent rag.
5.2. Air nozzle, fluid nozzle and needle assembly
5.2.1. To clean the nozzles, soak them in solvent to dissolve any dried material then blow them
clean with air. Handle all nozzles carefully
and do not make any alterations in the gun.
5.2.2. If you need to probe the holes in the nozzles, be sure to use a tool that is softer than brass; do not use metal instruments.
5.2.3. Adjust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.
5.3. Maintenance
Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check that
you have the correct part, or unscrew, realign and try again. DO NOT use excessive force when re-assembling.
5.3.1. Lubricate the gun daily with a light machine oil.
5.3.2. If you change the nozzle size, ensure the complete nozzle set is exchanged. Insert paint nozzle before putting the paint needle in.
5. CLEANING & MAINTENANCE
4. OPERATING INSTRUCTIONS
4.1. 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 finishing the stroke. This will enable you to accurately control the gun and material (fig 3).
4.2. Spray from a distance of about 6 to 10 inches 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 finish. To reduce over-spray and obtain
maximum efficiency, spray with the lowest possible atomizing air pressure.
4.3. Controlling the fan spray and the fluid.
a) Use the needle (paint) adjustment knob (fig 4.2) to increase or decrease the amount of paint flow.
b) The atomizing air flow is controlled by knob (1). The volume of air input is controlled by knob (3).
c) As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased area.
d) Turn the air nozzle (4) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (5).
The spray pattern of the gun is variable from round to flat with all patterns in between. In normal operation, the wings on the
nozzle are horizontal as fig 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 fig 6.

6. TROUBLESHOOTING
Dried material in a dirty side port restricts passage of air. Greater
flow of air from the cleaner 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 to thin or atomization air pressure too high.
Dirt between the fluid nozzle seat and body or loosely installed
fluid nozzle will cause the gun to spit.
Material bubbles or “boils” in paint cup. Atomised air flowing through the paint channel to pot.
The paint nozzle is not tight enough. Air nozzle is not completely
screwed in. The air net clogged and the seat is defective or
nozzle insert is damaged.
Tighten, clean or replace parts accordingly.
Dissolve material in the side ports with solvent, then blow the gun clean.
Do not poke into the opening with metal instruments.
Remove the air nozzle and wipe off fluid tip using a rag dampened with
solvent. Tighten the air nozzle
Regulate material viscosity or reduce air pressure
Remove the fluid nozzle, clean the back of the nozzle and the nozzle
seat in the gun body using a rag dampened with thinner. Replace the
nozzle and secure it tightly against the body.
VIEW OF PROBLEM POSSIBLE REASON FOR PROBLEM SOLUTION
A faulty spray is usually cause by improper cleaning or dried material around the fluid nozzle tip or in the air nozzle. Soak these parts in a
solvent that will soften the dried material and remove with a brush or a cloth. Never use metal instruments to clean the air or fluid nozzles.
These parts are carefully machined and any damage to them will cause a faulty spray. If either the air nozzle or fluid nozzle is damaged, the
part must be replaced before a perfect spay can be obtained.
