Installation
Important: To ensure that this
equipment reaches you in first class
condition, protective coatings have
been use. Flush the equipment
through with a suitable solvent
before use.
1. Attach air hose to connector (13).
Recommended hose size 8 mm
bore.
2. Air supply should be filtered and
regulated.
1. Turn off air supply and relieve
pressure in the airline, or if using
QD system, disconnect from
airline.
2. Empty coating material into a
suitable container and clean,
preferably in a gun wash
machine.
3. Remove air cap 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
4. Ensure the tip of the nozzle is
clean and free from damage.
Build up of dried paint can distort
the spray pattern.
5. Lubrication – stud/screw (6),
needle (7) and air valve (11)
should be oiled each day.
Preventative Maintenance
Operation
1. Mix coating material to
manufacturers instructions
2. Turn needle adjusting screw (10)
counter-clockwise until first thread
shows
3. Turn pattern valve (5) counter-
clockwise to fully open
4. Adjust inlet air pressure to give 2
bar (29psi) at the gun inlet with
the gun triggered. (pressure
gauge attachment shown under
Accessories is recommended for
this)
5. Test spray. If the finish is too dry
reduce airflow by reducing inlet
pressure. If finish is too wet
reduce fluid flow by turning needle
screw (10) clockwise. If
atomisation is too coarse,
increase inlet air pressure. If too
fine reduce inlet pressure.
6. The pattern size can be reduced
by adjusting valve (5)
7. Hold gun perpendicular to surface
being sprayed. Arcing or tilting
may result in uneven coating.
8. The recommended spray distance
is 150-200 mm (6”-8”).
9. Spray edges first. Overlap each
stroke a minimum of 50%. Move
gun at a constant speed.
10. Always turn off air supply and
relieve pressure when gun is not
in use.
Air Flow Valve (15)
1. If the airflow valve (15) is fitted
this can be used to reduce the
inlet pressure through the gun.
Screw the Adjusting Knob in to
reduce pressure.
