SPRAY GUN LUBRICATION
Daily, apply a drop of SSL-10* spray gun
lube at trigger bearing stud (28) and the
stem of air valve (20) where it enters air valve
assembly. The shank of fluid needle (11)
where it enters packing nut (9) should also
be oiled. Fluid needle packing (8) should be
lubricated periodically. Make sure baffle (6)
and retaining ring (3) threads are clean and
free of foreign matter. Before assembling
retaining ring to baffle, clean the threads
thoroughly, then add two drops of SSL-10
spray gun lube to threads. Fluid needle
spring (14) and air valve spring (19) should
be coated with a very light grease, making
sure that any excess grease will not clog
the air passages. For best results, lubricate
the points indicated, daily.
