Installation
Important: To ensure that this equipment
reaches you in first class condition,
protective coatings have been used.
Flush the equipment through with a
suitable solvent before use.
1. Attach air hose to connector (13).
Recommended hose size 8 mm bore.
The hose must be conductive and
electrical bond from the spraygun to
earth should be checked with an
ohmeter. A resistance of less than
10
6
Ohms is recommended.
2. Air supply should be filtered and
regulated.
3. Attach Cup assembly (22) by
screwing into the Fluid Inlet of the
spraygun. Tighen when fully home.
1. Turn off air and relieve pressure in
the supply lines, or if using QD
system, disconnect from airline.
2. Remove Cup Lid (20)and empty
coating material into a suitable
container. Clean the gun and cup,
preferably in a gun wash machine.
Clean the cup.
3. Check the breather hole in the Lid
and the Drip Check Lid is not
blocked.
4. Remove air cap (1) and clean. If any
of the holes in the cap are blocked
with coating material use a toothpick
to clean. Never use metal wire which
could damage the cap and produce
distorted spray patterns
5. Ensure the tip of the nozzle (2) is
Preventative Maintenance
Operation
1. Mix coating material to manufacturers
instructions.
2. Fill the cup with the required amount
of material. Fill to no more than 25mm
(1“) from the top of the cup. DO NOT
OVERFILL.
3. Attach Cup Lid.
4. Turn needle adjusting screw (7)
clockwise to prevent movement.
5. Turn spreader valve (5) counter-
clockwise to fully open.
6. Adjust inlet air pressure (For
r e c o m m e n d e d f i g u r e s s e e
Specifications) at the gun inlet with the
gun triggered.
(pressure gauge
attachment shown under Accessories
is recommended for this).
7. Turn needle adjusting screw counter
clockwise until first thread shows.
8. Test spray. If the finish is too dry
reduce airflow by reducing air inlet
pressure or by the Airflow Valve (14).
Screw the Adjusting Knob (14) in to
reduce pressure.
9. If finish is too wet reduce fluid flow by
turning needle screw (7) clockwise. If
atomisation is too coarse, increase
inlet air pressure. If too fine reduce
inlet pressure.
10. The pattern size can be reduced by
turning adjusting valve (5) clockwise.
11. Hold gun perpendicular to surface
being sprayed. Arcing or tilting may
result in uneven coating.
12. The recommended spray distance is
150-200 mm (6”-8”).
13. Spray edges first. Overlap each stroke
a minimum of 50%. Move gun at a
constant speed.
14. Always turn off air supply and relieve
pressure when gun is not in use.
