Shutdown and Care
WARNING
INJECTION HAZARD
To reduce the risk of serious injury, when
instructed to relieve pressure, follow the
Pressure Relief Procedure on page 8.
1. Relieve pressure.
2. Check packing nut daily. Keep packing nut full of
TSL at all times to help prevent fluid buildup on
piston rod and premature wear of packings.
3. If pump begins to leak, loosen packing nut and
remove throat nut spacer (228). Tighten packing
nut just snug. Over tightening causes binding and
excessive packing wear. Use a round punch or
brass rod and light hammer to adjust nut. Refer to
Fig. 10. When leakage occurs again, repack pump.
4. Clean gun’s fluid filter often and whenever gun
is stored. Relieve pressure first. Refer to manual
307614.
5. Lubricate bearing housing after every 100 hours
of operation. Remove front cover. Apply several
drops of SAE 10 non-detergent oil in bearing
housing cavity (B). See Fig. 10.
CAUTION
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 damage
the sprayer or result in a loss of pressure or stalling.
6. Flush sprayer at end of each work day and fill it
with mineral spirits to help prevent pump corrosion
and freezing. See page 12.
7. For very short shutoff periods, leave suction
hose in paint, relieve pressure, and clean spray tip.
