PARTS FOR:
PAINT SPRAY GUN
Model: S701

3. AIR SUPPLY
Recommended supply system is shown below.
3.1. Ensure that the spray gun trigger is in the "off" position before connecting to the air supply.
3.2. You will require an air pressure between 30 and 40psi, and an air flow according to the specification.
pWARNING! Ensure that the air supply is clean and does not exceed 70psi 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 cause damage and/or personal injury.
3.3. Drain the air tank daily. Water in the air
line will damage the spray gun and
invalidate your warranty.
3.4. Clean compressor air inlet filter weekly.
3.5. 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 fittings must have the same
inside dimensions.
3.6. Keep hose away from heat, oil and sharp
edges. Check hoses for wear, and make
certain that all connections are secure.
4. OPERATING INSTRUCTIONS
4.1. For best results, handle the gun correctly. It 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 give more accurate
control of the gun and the material (see right).
4.2. Spray from a distance of 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 fluid and the fan spray:
a) As the width of the spray is altered so the fluid flow
must be adjusted to maintain the same coverage.
c) The direction of the fan spray, either horizontal
or vertical, is adjusted by turning the air nozzle
to the desired position and then tightening the
retaining ring.
Disconnect form the air supply before attempting any maintenance or cleaning. When reassembling after
maintenance, be sure to take care when screwing parts together. At first 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 reassembling.
5.1. Spray gun
5.1.1. Immerse the front end of the gun only in solvent until the solvent
just covers the fluid connection.
5.1.2. Use a bristle brush and solvent to wash off accumulated paint.
5. MAINTENANCE & CLEANING
5.1.3. Do not immerse the entire gun in solvent. This will cause lubricants to dissolve and packing to
dry out. Dirty solvent may also clog the narrow passages in the gun.
5.1.4. Wipe the outside of the gun with a dampened solvent rag.
5.1.5. Lubricate the gun daily with a light machine oil. Be sure to lubricate the fluid needle packing, air valve
packing, side port control packing and trigger pivot point. Do not use lubricants containing silicone.
5.1.6. When finished spraying, flush the gun through with clean thinners.
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.
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 pas-
sage 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.
A split spray or one that is heavy on
each end of a fan pattern and weak
in the middle is usually caused by
too high an atomization air pressure
or by attempting to get too wide a
spray with thin material.
1. Dirt between the fluid nozzle seat
and body or loosely installed fluid
nozzle will cause the gun to spit.
2. A loose or defective swivel nut
on the siphon cup or material hose
can cause spitting.
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 is
clogged and the seat is defective or
nozzle insert is damaged.
Tighten, clean or replace parts
accordingly.
Dissolve material in the side ports
with thinner, 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
thinner. Tighten the air nozzle
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.
1. 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.
2. Tighten or replace the swivel nut.
VIEW OF PROBLEM THE CAUSE THE 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 spray can be obtained.
