Lubrication:
Regularlubricationisimportanttomaintainthehigh
performance of your HVLP Automatic Spray Gun. Every
time your spray gun is cleaned, the oil that lubricates the
friction points is washed away.
You must lubricate all working threads after every
cleaning. We recommend using a lubricant such as
petroleum jelly. Using lubricants containing silicone
can contaminate your entire finishing department. The
following illustrations identify the spray gun lubrication
points.
