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.
Preventative Maintenance
Operation
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 (For
recommended figures see
Specifications) 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.
