Lubrication
extreme care
Lubrication procedures must be ob-
when using any solvent or thin-
ner. Never clean gun near fire,
flame, or any source of heat or
sparks. Properly dispose of
used cleaning materials.
DO NOT soak
entire spray gun
in solvent or thinner for a long
period of time as this will de-
stroy lubricants and possibly
make motion uneven. NEVER
use lye or caustic alkaline solu-
tion for cleaning. Such solutions
will attack
aluminum alloy parts
of gun.
It is important that spray gun be
cleaned after daily use. Cleaning is ac-
complished
by spraying appropriate
solvent or thinner through system.
Wipe exterior of spray gun with
solvent soaked cloth or use cleaning
brush(s) provided to remove any accu-
mulated material.
Cleaning
(a) Empty material from gravity feed
cup and replace with a suitable
solvent.
(b) Operate trigger until all material
traces have disappeared
and gun
is thoroughly
clean.
(c)
Clean air cap with brush.
IMPORTANT: Make certain air cap
and fluid nozzle are kept clean at all
times. If necessary, remove these
two components
and soak them in
solvent. DO NOT use hard objects
to clean clogged holes. The
smallest amount of damage may
cause irregular spray pattern.
NOTE: If fluid nozzle is to be re-
moved for thorough
cleaning, squeeze
trigger to prevent damage of fluid
needle tip when unscrewing
nozzle.
served after thoroughly cleaning the
