Shutdown and Care
WARNING
INJECTION HAZARD
To reduce the risk of serious injury,
whenever you are instructed to relieve
pressure, follow the Pressure Relief
Procedure on page 8.
1.
Relieve pressure.
2.
Check the packing nut/wet-cup daily. 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.
3.
Tighten the packing nut/wet-cup 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. 9.
4.
Clean the gun’s fluid filter often and whenever
the gun is stored. Relieve pressure first. Refer to
manual 307–614.
5.
Lubricate the bearing housing after every 100
hours of operation. Remove the front cover. Apply
several drops of SAE 10 non-detergent oil in the
bearing housing cavity (B). See Fig. 10.
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 12.
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 seri-
ously 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.
INJECTION HAZARD
See the warning section INJECTION
HAZARD on page 3 for information on
the hazard of using damaged hoses.
