SHUTDOWN AND CARE
To reduce the risk of serious bodily injury, including
fluid injection or splashing in the eyes or on the skin,
or injury from moving parts, always follow the
Pres-
sure Relief Procedure Warning
on page 14 before
checking, adjusting, cleaning and shutting down the
sprayer.
WARNING
1. Check the packing nut/wet–cup daily.
First follow
the
Pressure Relief Procedure W arning
on page
14. Be sure the wet–cup is 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 just enough to stop
leakage.
Over tightening causes binding and exces-
sive packing wear. Use a round punch or brass rod
and light hammer to adjust the nut.
Refer to Fig 13–1.
3. Clean the fluid filter often
and whenever the spray-
er is stored. First follow the
Pressure Relief Proce-
dure W arning
on page 14. Refer to manual
307–273, supplied, for the cleaning procedure.
4. Lubricate the bearing housing
after every 100
hours of operation. Remove the front cover. Fill the
bearing housing cavity with SAE 10 non–detergent
oil. Refer to Fig 13–2.
5. Flush the sprayer at the end of each work day
and
fill it with mineral spirits to help prevent pump corro-
sion and freezing. Refer to
FLUSHING GUIDE-
LINES
on page 14.
CAUTION
To prevent pump corrosion, and to reduce the
chance of fluid freezing in the pump or pressure con-
trol 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. For very short shutoff periods,
leave the suction
tube in the paint, follow the
Pressure Relief Proce-
dure Warning
on page 14, and clean the spray tip.
7. Coil the hose and hang it on the hose rack
when
storing it, even for overnight, to help protect the hose
from kinking, abrasion, coupling damage, etc.
Refer to the warning section,
HOSE SAFETY,
on
page 5, for information on the hazard of using dam-
aged hoses.
