Preventative Maintenance
Operation
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 the Cup Lid assembly (27) to
the Fluid Inlet connector (15).
3. Position the Yoke at right angles to the
Gun with the Cam lever (21) to the
front (see picture). Make sure the vent
hole in the lid is positioned under the
Yoke and the hole in the diaphragm
(25) is 180° to the Lid vent hole.
1. Turn off air and relieve pressure in
the supply lines, or if using QD
system, disconnect from airline.
2. Release Cup and raise the tube out
of the material. Trigger the Gun and
allow material to drain back into the
cup. Dispose of the surplus material.
3. Clean the cup. Remove the Drip free
diaphragm and clean. Replace the
diaphragm if is split or damaged.
4. Check the breather hole in the Lid is
not blocked.
5. 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
6. Ensure the tip of the nozzle (2) is
clean and free from damage. Build up
of dried paint can distort the spray
pattern.
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 to the Lid assembly.
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 to give 3 bar
(44 psi) 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 or
reducing the fluid pressure. 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.
