FOR OPTIMUM PERFORMANCE IT IS VERY IMPORTANT TO ENSURE THE GUN IS CORRECTLY CLEANED AFTER EACH USE.
Disconnect form 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. The solvent should just cover the fluid connection.
5.1.2. Use a bristle brush and solvent to wash off accumulated paint.
5.1.3. 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.
5.1.4. Flush the gun through with clean thinners.
5.1.5. Wipe the outside of the gun with a dampened solvent rag.
5.2.
Air nozzle, fluid nozzle and needle assembly
5.2.1. To clean the nozzles, soak them in solvent to dissolve any dried material then blow them clean with air. Handle all nozzles carefully
and do not make any alterations in the gun.
5.2.2. If you need to probe the holes in the nozzles, be sure to use a tool that is softer than brass; do not use metal instruments.
5.2.3. Adjust the fluid needle valve so that when the gun is triggered, air flow occurs before fluid flow.
5.3.
Further cleaning hints and tips
5.3.1. When cleaning with a cup, a compatible solvent should be siphoned through the gun by inserting the tube from the siphon cup in an
open container of solvent. Trigger the gun intermittently to thoroughly flush passageways and internal parts.
5.3.2. When cleaning with a pressure cup, shut off the air supply to the pressure tank and release the pressure in the tank. Hold a piece of
cloth over the gun nozzle and pull the trigger. The air will back up through the fluid nozzle and force the fluid out of the hose and into
the tank. Remove paint from the tank, clean the tank and put enough compatible solvent into the tank to clean the hose and gun
thoroughly. Spray this through the gun while triggering the gun intermittently until it is clean, then blow out the fluid hose to dry it.
Remove all traces of materials by attaching it to the air line.
5.4.
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
you have the correct part, or unscrew, realign and try again.
DO NOT
use excessive force when re-assembling.
5.4.1. Lubricate the gun daily with a light machine oil.
5.4.2. If you change the nozzle size, ensure the complete nozzle set is exchanged. Insert paint nozzle before putting the paint needle in.
5.4.3. To change the needle packing use the socket spanner provided. Note: Handle the teflon seal and self tensioning spiring with care.
5. CLEANING & MAINTENANCE
4. OPERATING INSTRUCTIONS
4.1.
For best results, make sure to handle the gun correctly. It 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).
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 needle adjustment knob (fig 4.2) to increase or decrease the amount of paint flow.
b) The atomizing air flow is controlled by knob (1).
b) As width of spray is increased more material must pass through the gun to obtain the same coverage on the increased area.
c) Turn the air nozzle (3) to achieve a horizontal or vertical fan spray. Lock the nozzle with retaining ring (4).
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 as fig 4. 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 5.
