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 7.
1. Check packing nut (A) daily. First relieve pressure.
Keep packing nut full of TSL at all times to help
prevent fluid buildup on piston rod and premature
wear of packings.
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. 6. When leakage occurs again, repack the
pump.
2. Clean fluid filter often
and whenever sprayer is
stored. Follow Flushing Guidelines on page 10 for
cleaning procedure.
3. Lubricate bearing housing
after every 100 hours of
operation. First relieve pressure. Remove front
cover (49). Fill bearing housing cavity (B) with SAE
10 non-detergent oil. See Fig. 7.
4.
For very short shutoff periods, leave suction tube
in paint, relieve pressure, and clean spray tip.
5.
Flush sprayer at end of each work day
and fill it
with mineral spirits to help prevent pump corrosion
and freezing. See page 10.
CAUTION
To prevent pump corrosion, never leave water or any
type of paint in the sprayer when it is not in use.
Pump water or paint out with mineral spirits.
6. Coil hose and hang it on hose rack
when storing it,
even for overnight, to help protect hose from kink-
ing, abrasion, coupling damage, etc.
