5. OPERATION
5.1.
For best results, the gun should be held perpendicular to the surface being sprayed and moved parallel to it. Start the stroke before
squeezing the trigger and release the trigger before finishing the stroke. This will enable you to accurately control the gun and material (fig.3).
5.2.
Spray from a distance of about 150mm to 250mm depending on the material and the atomizing pressure. The material deposited should
always be even and wet. Each stroke must overlap the preceding stroke to obtain a uniform finish. To reduce over-spray and obtain
maximum efficiency, spray with the lowest possible atomising air pressure.
5.3.
Controlling the fan spray and the fluid.
a) Use the needle (paint) adjustment knob (fig.4.2) to increase or decrease the amount of paint flow.
b) The atomizing air flow is controlled by knob (4.1). The volume of air input is controlled by knob (4.3).
c) As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased area.
d) Turn the air nozzle (4.4) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (4.5).
The spray pattern of the gun is variable from round to flat with all patterns in between. In normal operation, the wings on the nozzle
are horizontal. See fig.5. This provides a vertical fan-shaped pattern which gives maximum uniform and even coverage when moving
the gun back and forth, parallel to the work surface.

6. CLEANING & MAINTENANCE
FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE GUN IS CORRECTLY CLEANED AFTER EACH USE
Disconnect from the air supply before attempting any cleaning or maintenance.
6.1.
Cleaning the gun
6.1.1.
Immerse the front end of the gun only in solvent. The solvent should just cover the
fluid connection. (fig.6).
6.1.2.
Use the bristle brush (fig.7) and solvent to wash off accumulated paint.
6.1.3.
Do not immerse the entire gun in solvent as this will cause lubricants on the
rubber seals to dissolve. Dirty solvent may also clog narrow passages in the gun.
6.1.4.
Flush the gun through with clean solvent.
6.1.5.
Wipe the outside of the gun with a dampened solvent rag.
