SHUTDOWN AND CARE
Check the packing nut/wet-cup daily. First follow the
Pressure Relief Procedure Warning on page 10.
Keep the wet-cup l/3 full of throat seal liquid at all
times to help prevent fluid buildup on the piston rod and
premature packing wear. The packing nut should be
tight enough to stop leakage, but no tighter. Over-
tightening may cause binding and excessive packing
wear. Use a screwdriver and light hammer to adjust the
nut. See Fig 5.
Fig 5
CAUTION
When adjusting the packing nut, be careful not to
nick the cylinder threads which may be protruding
above the bearing housing. Nicks to these threads
may strip the threads in the bearing housing when
the displacement pump is removed or installed.
Flush the sprayer at the end of each work day and fill it
with mineral spirits to help prevent pump corrosion and
freezing. See “Flushing Guidelines” on’page 12.
CAUTION
Never leave water or any type of paint in the
sprayer over night to: (1) prevent pump corrosion;
(21 to prevent the fluid from freezing in the pump
and pressure control which can cause loss of
pressure, stalling or serious sprayer damage.
Always use mineral spirits for the final flush.
Relieve pressure. This leaves a protective coating
of mineral spirits in the pump.
For very short shutoff periods, leave the suction tube in
the paint, follow the Pressure Relief Procedure
Warning, page 10, and clean the spray tip.
Coil the hose and hang it on the hose rack when storing
the sprayer, even for overnight, to help protect the hose
from kinking, abrasion, coupling damage, or other
damage.
