when instructed in this procedure to
1. Check the packing nutbetcup daily. Relieve
pressure
fi r st.
Keep the wet-cup 1/3 full of TSL at
all times to help prevent fluid buildup on the pis-
ton rod and premature wear of packlngs.
2.
lighten the packing nuffwetcup just enough to
stop leakage. Over-tightening causes binding
and excessive packing wear. Use a round punch
or brass rod and a light hammer to adjust the nut.
See Fig 10.
3. Clean the gun's fluid filter often and whenever
the gun is stored. Relieve pressure first. Refer to
manual 307-614.
4.
Periodically clean paint residue from the p r e s
sure transducer vent hole area. See Fig 11. Re-
place the transducer when leakage is excessive.
See page

it
with mineral spirits to help prevent pump
corrosion and freezing. See page 13.

chance.of fluid freezing in the pump in cold
the sprayer when it is not in use. Freezing can
weather, never leave water or any type of paint
