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 Attach fluid supply hose to Fluid
Inlet
(15).
1. Turn off air and coating supply and
relieve pressure in the supply lines,
or if using QD system, disconnect
from airline and fluid line.
2. 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
3. Ensure the tip of the nozzle (2) is
clean and free from damage. Build
up of dried paint can distort the spray
pattern.
4. Lubrication – stud/screw (6), needle
(9) and air valve (11) should be oiled
each day.
Preventative Maintenance
E E
Operation
1. Mix coating material to manufacturers
instructions
2. Turn needle adjusting screw (7)
clockwise to prevent movement.
3. Turn spreader valve (5) counter-
clockwise to fully open.
4. Adjust inlet air pressure to give 3 bar
(44 psi) at the gun inlet with the gun
t r i g g e r e d .
( p r e s s u r e g a u g e
attachment shown under Accessories
is recommended for this).
5. Turn needle adjusting screw counter
clockwise until first thread shows.
6. 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.
7. If finish is too wet reduce fluid flow by
turning needle screw (7) clockwise or
reducing the fluid pressure. If
atomisation is too coarse, increase
inlet air pressure. If too fine reduce
inlet pressure.
8. The pattern size can be reduced by
turning adjusting valve (5) clockwise.
9. Hold gun perpendicular to surface
being sprayed. Arcing or tilting may
result in uneven coating.
10. The recommended spray distance is
150-200 mm (6”-8”).
11. Spray edges first. Overlap each
stroke a minimum of 50%. Move gun
at a constant speed.
12. Always turn off air and fluid supply
and relieve pressure when gun is not
in use.
