Shutdown And Care - Graco 231-043 Instructions-Parts List Manual

WARNING
To reduce the risk of serious injury, follow the illus-
trated Pressure Relief Procedure
page 4 whenever you are instructed to relieve pres-
sure.
1. Check the packing nut/wet-cup daily. First relieve
pressure. 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.
Tighten the packing nut just enough to stop leakage.
Over tightening causes binding and excessive pack-
ing wear. Use a round punch or brass rod and light
hammer to adjust the nut. Refer to Fig 14–1.
2. Clean the fluid filter often and whenever the spray-
er is stored. Follow the Flushing Guidelines on page
15 or refer to manual 307–273, supplied, for the
cleaning procedure.
3. Lubricate the bearing housing
hours of operation. First relieve pressure. Remove
the front cover. Fill the bearing housing cavity with
SAE 10 non-detergent oil. See Fig 14–2.
4. For very short shutoff periods, leave the suction
tube in the paint, relieve pressure, and clean the
spray tip.
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. See 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 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. 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.
