Shutdown and Care of the Sprayer
WARNING
To reduce the risk of a serious injury, follow the
Pressure Relief Procedure on page 4 whenever
you are instructed to relieve the pressure.
1. Check the packing nut (216) daily. Relieve the
pressure. Keep the packing nut 1/3 full of TSL at
all times to help prevent fluid buildup on the piston
rod and the premature wear of the packings.
Tighten the packing nut (216), in the direction
shown by the bold arrow, just enough to stop leak-
age. Do not over–tightening the packing nut which
may cause it to binding and may cause the pack-
ings to wear prematurely. Use a round punch or a
brass rod and a lightweight hammer to adjust the
nut. See Fig. 6.
2. Clean the fluid filter (66) at least once a day.
Follow the flushing procedure on page 15 or refer
to manual 307–273, for the cleaning procedure.
3. Lubricate the bearing housing (69) after each 100
hours of operation. Relieve the pressure. Remove
the front cover (49). Fill the cavity in the bearing
housing with SAE 10, non-detergent oil. See Fig.
6.
4. For very short shutoff periods, leave the suction
tube in the paint, relieve the pressure, and clean
the spray tip.
5. Flush the sprayer at the end of each work day. The
final flush should be mineral spirits. See page 15.
CAUTION
To prevent serious damage to the pump, which can
result in poor sprayer performance and costly
repairs, follow these precautions.
Do not allow water or any type of paint to
freeze in the sprayer or the pressure control.
Always flush with a compatible solvent and then
flush again with mineral spirits when you are
done spraying.
6. Coil the hose and hang the hose on the hose rack
when storing the sprayer, even for overnight.
