INStRUCtIONS
4.1.
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 accurate control of the gun and material (Fig.3B).
4.2.
Spray from a distance of about 6 to 10 inches 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 atomizing air pressure.
4.3.
Controlling the fan spray and the fluid.
a) Use the fluid control knob (Fig.4) to adjust the amount of paint flow. Turning it clockwise will decrease flow and anticlockwise will
increase flow.
b) The spray width is controlled by the spray width adjustment knob, turn clockwise for a round pattern and anticlockwise for a fan pattern.
Note: as width of spray is increased, more paint must be allowed through the gun to obtain the same coverage in the increased area.
c) Turn the air nozzle to achieve a horizontal or vertical fan spray. Lock the nozzle with the retaining ring.
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 (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 (Fig.6).

CLEANING AND MAINtENANCE
FOR OPtIMUM PERFORMANCE It IS VERY IMPORtANt tO ENSURE tHE SPRAY GUN IS CORRECtLY CLEANED AFtER EACH USE.
Disconnect from the air supply before attempting any cleaning or maintenance.
5.1.
Cleaning the gun
5.1.1. Immerse the front end of the gun only in solvent, until the solvent just covers
the fluid connection.
5.1.2. Do not immerse the entire gun in solvent. This will cause lubricants to
dissolve and packing to dry out. Dirty solvent may also clog the narrow
passages in the gun.
5.1.3. Use a bristle brush and solvent to wash off accumulated paint.
5.1.4. Wipe the outside of the gun with a dampened solvent rag.
5.1.5. When finished spraying, flush the gun through with clean solvent.
5.1.6. If required, clean the nozzles by soaking them in solvent to dissolve any dried
material and then use a brush. Blow them clean with air. Handle all nozzles
carefully and do not make any alterations in the gun (except as in 5.1.8. below).
5.1.7. If there is a need to probe the holes in the nozzles, ensure a tool that is softer
than brass is utilised, under no circumstances use a metal tool, as the slightest amount of damage will adversely affect the spray pattern.
5.1.8. Adjust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.
5.2.
Maintenance
Take care when re-assembling. Screw parts hand tight to avoid cross-threading. If a part cannot easily be turned by hand, check that
it is the correct part, or unscrew it, realign and retry. DO NOt use excessive force when re-assembling.
5.2.1. When changing the nozzle size, ensure the complete nozzle set is fitted. This consists of air cap, fluid nozzle and paint needle. Insert the
fluid nozzle before paint needle.
