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.
