Shutdown and Care
WARNING
To reduce the risk of serious injury, follow the
Pressure Relief Procedure Warning
on
page 11
before doing this procedure. Unplug the sprayer!
1. Check the packlng nWwet-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
punch or brass rod and a light hammer to adjust
binding and excessive packing wear. Use a round
the nut. See Fig.
8.
3. Clean the gun's fluid filter often and whenever
the gunis stored. Relieve pressure
first.
Refer to
manual 307-614.
4.
Periodically clean paint residue from
the pres-
sure transducer (29) vent hole area. See Fig. 9.

Lubricate the bearing houslng
after every 100
the bearing housing cavity (A) with SAE 10 non-
hours of operation. Remove the front cover. Fill
detergent oil. See Fig.
9.
6. 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 14.
CAUTION
To prevent pump corrosion, and to reduce the
chance of fluid freezing in the pump in cold
the sprayer when it is not in use. Freezing can se-
weather, never leave water or any,type of paint in
riously damage the sprayer or result in
a loss
of
pressure or stalling.
7. For very short shutoff periods, leave the suction
hose in the paint, relieve pressure, and clean the
spray tip.
8.
Coil the hose when storing
it,
even for overnight,
to help protect the hose from kinking, abrasion,
coupling damage, etc.
