PREVENTIVE MAINTENANCE

SPRAY GUN LUBRICATION

Daily, apply a drop of gun lube at trigger stud screw (15) and
the stem of the air valve (12) where it enters the air valve
assembly. The shank of the fluid needle where it enters the
packing nut should also be lubricated. Make sure baffle

and retaining ring threads are clean and free of foreign
matter. Before assembling air cap to baffle, clean the
retaining ring and baffle threads

thoroughly, then add

two drops of spray gun lube to threads.

The fluid needle spring (4), and air valve spring (13), should
be coated with a very light grease, ensuring that any excess
grease will not clog the air passages. For best results, lubri­cate the points indicated daily using SSL-10 spray gun lube.

C. Adjusting valve
D. Baffle and retaining ring threads
E. Air valve c

artridge

FOR HVLP GUNS ONLY:

NOTE

If the baffle is removed, baffle gasket (7) and
O-ring (8) should be replaced. To prevent damage
to the O-ring during installation, apply gun lube
to exterior of O-ring and ID of baffle.

To clean air cap and fluid tip, brush exterior with a stiff bris­tle brush. If necessary to clean cap holes, use a broom straw
or toothpick. Never use a wire or hard instrument. Th

is

may scratch or burr holes causing a distorted spray pattern.

To clean fluid passages, remove excess material at source,
then flush with a suitable solvent using a device such as the
Solvent Saver

TM

. Wipe gun exterior with a solvent dampened
cloth. Never completely immerse in solvent as this is detri­mental to the performance and gun life expectancy, as well
as destroying the lubricants and packings.

FOR GUNS WITH S.S. FLUID INSERTS ONLY:

To prevent serious gun damage, do not remove
the fluid tip if the fluid inlet adapter has been
removed. The stainless steel fluid insert can break
free (which is non-repairable). Remove the fluid tip
before

removing the fluid inlet adapter. Use a new

gasket before reinstalling the fluid inlet adapter.

To prevent damage to the fluid tip or fluid needle,
be sure to either 1) pull the trigger and hold while
tightening the fluid tip, or 2) remove fluid needle
adjusting screw to relieve spring pressure.
