Shutdown & Care - Graco 231–081 Instructions And Parts List

WARNING
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 12 before
checking, adjusting, cleaning and shutting down the
sprayer.
1. Check the packing nut/wet–cup daily. First relieve
pressure. 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. The packing nut
should be tight enough to stop leakage, but no
tighter. Overtightening may cause binding and ex-
cessive packing wear. Use a round punch or brass
rod and light hammer to adjust the nut. See Fig 6.
2. Clean the fluid filter often and whenever the spray-
er is stored. First relieve pressure. Refer to manual
307–273, supplied, for the cleaning procedure.
3. Lubricate the bearing housing
hours of operation. Remove the front cover . Fill the
bearing housing cavity with SAE non–detergent oil.
See Fig 7.
4. Flush the sprayer at the end of each work day and
fill it with mineral spirits to help prevent pump corro-
sion and freezing. See FLUSHING GUIDELINES on
page 15.
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
material in the sprayer when it is not in use. Freezing
can seriously damage the sprayer or result in a loss
of pressure or stalling.
5. For very short shutoff periods, leave the suction
tube in the material, relieve pressure, and clean the
spray tip.
6. 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.
