ADJUSTMENT OF SPRAY
In normal operation the wings on the nozzle are
horizontal as illustrated in Fig. 4. This provides a
vertical fan shaped pattern which gives maximum
coverage as the gun is moved back and forth
parallel to the surface being finished.
1. The first requirement for a good finish is proper
handling of the Spray gun. The gun should be held
perpendicular to the surface being covered, and moved
parallel with it. The stroke should be started before the
trigger is pulled and the trigger should be released before
the stroke is ended. This gives accurate control of gun and
material. See Fig. 1 and Fig. 2.
2. Adjusting spray pattern. Turn the pattern adjusting
knob completely to the right for a circular spray pattern,
completely to the left for oval shaped spray pattern
3. Adjusting spray volume. Turn fluid control screw
clockwise to reduce volume, counter-clockwise to increase
volume.
4. Adjusting air flow. Turn the air regulator dial clockwise
to reduce air volume, counter-clockwise to increase air
volume.
MAINTENANCE
Before making any adjustments or changing any
accessory, turn off the tool, unplug it from it's air
source and discharge any residual air pressure.
If painting is paused for only a few minutes, the machine can be left without cleaning. If the spray gun will be left to
sit for a few hours or more before its next use, it must be cleaned to prevent the paint from drying inside the ducts.
1. After you have finished painting, pour the remaining paint into another container and then clean paint
passage and air cap. Spray a small amount of thinner to clean paint passages. Incomplete cleaning will
cause adverse pattern shapes and particles to appear on your work. Promptly clean components after use.
2. Add clean, good quality solvent to the tank and then pull the trigger to clean the internal paint spray
gun's passages from all traces of paint before disassembly.
3. Unscrew and remove the paint spray gun's head, submerge it in solvent and brush it clean. Do not use
metal objects for cleaning.
4. After removing the needle, unscrew the nozzle using the correct wrench, insert it in solvent and brush
it clean. Wash the inside of the paint spray gun and brush it clean; do not submerge it completely in the
solvent.
5. The outside of the body must be cleaned with a clean cloth dipped in solvent.
6. Lubricate the moving parts with grease or Vaseline from time to time. Do not use lubricants that contain
silicone.
7. Regularly inspect all mountings and screws to ensure tightness. Should any screws become loose,
tighten immediately.
8. If repair is required, take the tool to an authorized service center.
CAUTION:
Never use wire or other sharp, pointed objects to clean nozzle or fluid needle. The smallest amount of
damage may badly influence the spray pattern. Never immerse spray gun completely in thinner or solvent.
When re-assembling, always dry parts thoroughly to prevent dust build up.
