Important:
equipment reaches you in first class
condition, protective coatings have
been used. Flush
through with a suitable solvent
before use.
1. Attach air hose to connector (13).
Recommended hose size 8 mm

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 (For
r e c o m m e n d e d
Specifications) at the gun inlet with
the gun triggered. (pressure gauge
a t t a c h m e n t
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.
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

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
recommended.
2 Attach fluid supply hose to Fluid
Inlet (15).

Operation

t o 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
s e e 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.
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.
