PREVENTIVE MAINTENANCE
1. Daily lubrication and cleaning are necessary to maintain the best condition of the gun.
2. To clean the gun body, wipe exterior with solvent or cleaning solution dampened cloth.
Do not immerse the gun in a solvent or cleaning solution as it may damage the gun or
cause painting problems.
3.
After using the gun, remove the paint and then pass an appropriate solvent or cleaning
solution through the paint path to wash away any remaining paint.
4.
Do not leave any solvent or cleaning solution in the paint path or paint cup. It may cause
corrosion or damage.
5. The AIR CAP (2) can be immersed in solvent and brushed down for cleaning. If orifices
are clogged, use a toothpick to remove obstruction. Never use a steel wire or hard
instrument. This will damage air cap and result in a distorted spray pattern.
6. The following portions should be lubricated regularly (

For lubrication, SSL-10 Gun Lube* is recommended. (*Sold separately, contains NO
silicones or petroleum distillates.)
