Important: To ensure that this equipment
reaches you in first class condition,
protective coatings have been use. Flush
the equipment through with a suitable
solvent before use.
1. Attach air hose to connector (15).
Recommended hose size 8 mm
1. Mix coating material to manufacturers
instructions.
2. Screw Cup (19) to Gun. Do not over
tighten.
3. Place the filter (24) in the cup and fill
to required level with paint, or use
funnel (SRI-17) and use paper filter.
Screw on lid.
4. Turn needle adjusting screw (5) fully
clockwise to shut off fluid (for setting
up air supply pressure).Turn spreader
valve (6) counter-clockwise to fully
open.
5. Attach air supply to Gun and adjust
inlet air pressure up to 2 bar (29psi) at
the gun inlet with the gun triggered.
(pressure gauge attachments shown
under Accessories are recommended
for this).
6. Turn Needle Adjusting Screw

pressure. If finish is too wet reduce
fluid flow by turning needle screw (5)
clockwise. If
coarse, increase inlet air pressure. If
too fine reduce inlet pressure.
8. The pattern size can be reduced by
turning Spreader valve (6) clockwise.
9. Hold gun perpendicular to surface
being sprayed. Arcing or tilting may
result in uneven coating.
10. The recommended spray distance is
75-150 mm (3"-6").
11. Spray edges first. Overlap each
stroke a minimum of 50%. Move gun
at a constant speed.
12. Always turn off air supply and relieve
pressure when gun is not in use.
Air Flow Valve (17)
1. The airflow valve (17) is fitted to
reduce the inlet pressure through the
gun. Screw
clockwise to reduce pressure.
2. Empty coating material into a
suitable container and clean the gun
and cup, preferably in a gun wash
machine.
