CARE AND CLEANING
Spray Gun troubles are usually caused by neglect or improper cleaning.
Keep Gun lubricated.
Keep Packing Nuts around Fluid Needle and Air Valve Stem tight. Do not tighten so securely that parts
cannot move freely.
Keep Gun clean. It is not necessary to take spray gun apart to clean it. Spray clean solvent through gun
and wash off outside with clean solvent.
Do not allow Gun to get so dirty that soaking of complete gun becomes necessary.
Do not use caustic alkaline solutions for cleaning as they destroy aluminum alloy.
An unbalanced or distorted spray indicates a dirty air cap. Remove Air Cap and wash thouroughly in clean
solvent. If reaming of air cap holes is necessary, use match stick, broom bristle or other soft implement. Never
use a hard or sharp instrument for this purpose, as it may permanently damage the cap.
Do not remove spray gun parts unless absolutely necessary.
Check condition of gaskets when rmoving parts which seal On gasket.
Always make certain the FIuid NozzIe is securely tightened when replacing. The Fluid Nozzle size is 1"
