whenever you are instructed to relieve
pressure, follow the
Pressure Relief
Procedure
on page 9.
Shutdown and Care
1. Check the packing nut/wet-cup daily (102).
Re
-
lieve pressure first. Keep the wet-cup 1/3 full of
TSL at all times to help prevent fluid buildup on the
piston rod and premature wear of packings.
2. Tighten the packing nut/wet-cup (102) 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.
Periodically clean paint residue from the pres

sure transducer (29)
vent hole area. See Fig. 1

sive. See page 31.
4. Lubricate the bearing housing
after every 100
hours of operation. Remove the front cover
. Fill the
bearing housing cavity (A) with SAE 10 non-
detergent oil. See Fig. 1
1.
5. Flush the sprayer at the end of each work day
and fill it with mineral spirits to help prevent pump
corrosion and freezing. See page 13.
To
prevent pump corrosion, and to reduce the
chance of fluid freezing in the pump in cold weather
,
never leave water or any type of paint in the sprayer
when it is not in use. Freezing can seriously dam
-
age the sprayer or result in a loss of pressure or
stalling.
CAUTION
6. For very short shutoff periods,
leave the suction
tube in the paint, relieve pressure, and clean the
spray tip.
7. Coil the hose and hang it on a hose rack when
storing it, even for overnight, to help protect the
hose from kinking, abrasion, coupling damage, etc.
