WARNING: Prior to any servicing and repair work the spray gun must
be removed from atomizing air pressure and material inputs.
Procedures to always follow:
1. Always swap spray gun at spray station.
2. Always service spray gun immediately. The swapping and/or maintenance of a spray gun should
take about 5 minutes. If maintenance is not immediate and adhesive is allowed to dry, expect
servicing time of about 1 hour, not including the possible interruption in production if gun is not
prepared in a timely fashion.
Things to avoid:
1. Never maintain spray guns while attached to fluid line. This will allow adhesive to flow into
the air passageways of the spray gun body causing the compressed air to cure the adhesive,
increasing the maintenance time drastically.
2. Never use any petroleum-based product (i.e. solvent, petroleum jelly, etc.) to clean or lubricate
areas of spray gun where fluid may contact.
3. Never submerge spray gun in solvents or other cleaning fluids, as this will impair the functional
reliability and efficiency of the gun. This will cause more service over time.
Servicing procedures:
1. Remove spray gun from spray system and replace with serviced spray gun.
2. Flush excess adhesive from spray gun using water.
3. Remove air cap, fluid nozzle and needle.
4. Flush gun body with water until thoroughly clean. Make sure adhesive does not get inside air
passageways.
5. Clean all parts and remove any dried adhesive on these components and again flush thoroughly.
6. Assemble spray gun. Always install fluid nozzle before fluid needle. (If parts need replacement,
do it now. We only want fully serviced and repaired guns to be placed into production.)
7. Test for leaks using water. Turn spray gun upside down and fill with water. Check to see if
leaking at nozzle fluid nozzle. If leaking replaced both nozzle and needle. (Much easier when
done with water vs. after attaching to adhesive system)
8. Place in a convenient location for next use.
