PREVENTIVE MAINTENANCE
1. Daily lubrication and cleaning is necessary to maintain the best condition of the gun.
2. To clean the gun body, wipe exterior with solvent dampened cloth. Do not submerge the gun body in solvent as any
solids may get into the air passage causing troubles.
3. Do not leave the gun with solvent remained in the fluid cup. Clean the spray gun after use with clean solvent and by
emptying the cup. To clean the fluid cup after use, remove remaining paint through appropriate solvent and flush down
the residual paint.
4. The Air Cap 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.
5. Do not immerse any plastic parts in solvent for long time.
6. Certain portions of gun should be lubricated. Do not lubricate to any portion where not instructed. For lubrication,
SSL-10 Gun Lube* is recommended (*sold separately, vegetable oil that does not repel paint materials).
7. The following portions should be lubricated regularly; Trigger Bearing Stud Screw (16), Pattern Valve (14), and Adjusting
Screw (13), Air Valve Stem (15), and portion of Packing Gland (8) where Needle (11) comes in and out.
8. When installing Air Cap (4), make sure no foreign materials adhered on Retaining Ring (1) and thread of Baffle (6).
Inject one drop of Gun Lube SSL-10.
9. Apply non-silicone grease lightly on Needle Spring (12) and Air Valve Spring (15). Do not apply too much grease as it
may clog the air passage.
