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 Ohms is recommended.

2. ir supply should be filtered and
regulated.
3. ttach cup assembly by screwing
into the Fluid Inlet of the spraygun.
Tighten with a wrench.

OPER TION
1. Mix coating material to manufac-
turers 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. ttach cup lid.
4. Turn needle adjusting screw (7)
clockwise to prevent movement.
5. Turn spreader valve (5) counter-
clockwise to fully open.
6. djust inlet air pressure (For recom-
mended figures see Chart 1) at the
gun inlet with the gun triggered.
(pressure gauge attachment shown
under
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
(14). Screw the
in to reduce pressure.
9. If finish is too wet reduce fluid flow
by turning needle adjusting screw
(7) clockwise. If atomization is too
coarse, increase inlet air pressure. If
too fine reduce inlet pressure.
10. The pattern size can be reduced by
turning spreader valve (5) clockwise.
11. Hold gun perpendicular to surface
being sprayed. rcing or tilting may
result in uneven coating.
12. The recommended spray distance is
150-200 mm (6"-8").
13. Spray edges first. Overlap each
from the
stroke a minimum of 50%. Move gun
at a constant speed.
14. lways turn off air supply and
relieve pressure when gun is not in
use.
Front airvalve seal –
install as shown.
irvalve spring – install as
irvalve spindle (11)
shown with small diameter end
of spring facing gun front.

PREVENT TIVE M INTEN NCE
1. Turn off air and relieve pressure in
the supply lines, or if using QD
system, disconnect from airline.
2. Remove cup lid 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 end of the fluid tip (2) is
clean and free from damage. Build
up of dried paint can distort the
spray pattern.
6. Lubrication – stud/screw (6), fluid
needle (9) and air valve spindle (11)
should be oiled each day with gun
oil.
REPL CEMENT OF P RTS
Fluid Tip (2) and Fluid Needle (9) –
Remove parts in the following order: 7, 8,
9, 1 and 2. Replace any worn or damaged
parts and re-assemble in reverse order.
Recommended tightening torque for fluid
tip (2) 9.5-12 Nm (80-100 lbf in).
Needle 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
sufficient to seal but to allow free move-
ment of needle. Lubricate with gun oil.
ir Valve Seal Kit (16) – (Refer to photos
1 to 21 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.
Rear airvalve seal – install as shown with
groove facing front of gun.
