PARTS LIST
SPRAY GUN LUBRICATION
Daily, apply a drop of *SSL-10 gun lube at
trigger bearing stud (21) and the stem of
the air valve (13) where it enters the air
valve assembly (17). The shank of the fluid
needle (4) where it enters the packing nut
(19) should also be oiled. The fluid needle
packing (18) should be lubricated periodi-
cally. Make sure the baffle (6) and retaining
ring (2) 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. The fluid needle spring (30) and air
valve spring (12) should be coated with a
very light grease, making sure that any
excess grease will not clog the air pas-
sages. For best results, lubricate the points
indicated daily with SSL-10 spray gun lube.
