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.

CAUTION
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.
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
