INST LL TION
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. ttach air hose to connector (13).
Recommended hose size 8 mm
bore. The hose must be conductive
and electrical bond
spraygun to earth should be checked
with an ohmeter. resistance of less
than 10 6 Ohms is recommended.
2. ir supply should be filtered and
regulated.
3. ttach suction feed cup or fluid
supply hose to Fluid Inlet (15).
OPER TION
1. Mix coating material to manufac-
turers instructions and fill suction
or pressure pot with the material.
If using a suction cup, make sure
that the vent hole is cleared.
2. Turn needle adjusting screw (7)
clockwise to prevent movement.
3. Turn spreader valve (5) counter-
clockwise to fully open.
4. djust inlet air pressure (For recom-
mended figures see Specifications)
at the gun inlet with the gun trig-
gered. (pressure gauge attachment
shown under
mended 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
(14). Screw the
in to reduce pressure.
7. If finish is too wet reduce fluid flow
by turning needle screw (7) clock-
wise or reducing the fluid pressure.
If atomization 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) clock-
wise.
9. Hold gun perpendicular to surface
being sprayed. rcing 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. lways turn off air and fluid supply
and relieve pressure when gun is not
in use.

REPL CEMENT OF P RTS
irflow Valve Nozzle (2) and Needle (9) – Remove parts
djusting Knob (14) in the following order: 7, 8, 9, 1 and 2.
Replace any worn or damaged parts and
re-assemble
Recommended tightening torque for
nozzle (2) 9.5-12 Nm (80-100 lbf in).
Packing – Remove parts 7, 8, 9. Unscrew
cartridge (4). Fit new cartridge finger
tight. Re-assemble parts 9, 8, and 7 and
tighten cartridge (4) with spanner suffi-
cient to seal but to allow free movement
of needle. Lubricate with gun oil.
1 to 28 and fig 2)
Spreader valve (5) – Caution: always
ensure that the valve is in the fully open
position by turning screw fully counter-
clockwise before fitting to body.
SB-2-662-C
Turn off air and coating supply and
relieve pressure in the supply lines,
or if using QD system, disconnect
from airline and fluid line.
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
Ensure the tip of the nozzle (2) is
clean and free from damage. Build
up of dried paint can distort the
spray pattern.
Lubrication – stud/screw (6), needle
(9) and air valve (11) should be oiled
each day.
