SHUTDOWN
AND CARE
1. Check the packing nut/wetcup daily. First relieve
the pressure; see page 9. Be sure the wetcup 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
excessive
packing wear. See Fig 12–1.
2. Clean the fluid filter often and before storing the
sprayer. First relieve pressure; see page 9. See
manual 307–273, supplied, for the filter cleaning
procedure.
3. 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 the flushing guidelines on
pages
13 and 14.
Never
leave water or any paint in the sprayer over
-
night
to: (1) prevent pump corrosion; (2) prevent
the
fluid
from freezing in the pump and pressure control
which
can cause loss
of pressure, stalling or serious
sprayer
damage.
Always
use
mineral spirits for the final flush, relieve
pressure
and leave the mineral spirits in the sprayer
.
CAUTION
4. For very short shutoff periods, leave the suction
tube
in the paint, relieve the pressure, and clean the
spray tip.
5. Coil the hose and hang it on the cart’s hose rack
when
storing it, even for overnight, to help protect the
hose from kinking, abrasion, coupling damage, etc.
See
Fig 12–2.
6. For
the Lo–Boy cart,
use the brackets on the side of
the cart to hold the suction assembly. See the Parts
Drawing
on page 31.
7. Lubricate the bearing housing after every 100
hours
of operation. Remove the drive housing cover
.
Fill the bearing housing with SAE non-detergent oil.
See
Fig 12–3.
