Shutdown and Care
WARNING
INJECTION HAZARD
To reduce the risk of serious injury, when instructed to relieve pressure, follow the Pressure Relief Procedure on page 8.
1.Relieve pressure.
2.Check packing nut daily. Keep packing nut full of TSL at all times to help prevent fluid buildup on piston rod and premature wear of packings.
3.If pump begins to leak, loosen packing nut and remove throat nut spacer (228). Tighten packing nut just snug. Over tightening causes binding and excessive packing wear. Use a round punch or brass rod and light hammer to adjust nut. Refer to Fig. 10. When leakage occurs again, repack pump.
4.Clean gun’s fluid filter often and whenever gun is stored. Relieve pressure first. Refer to manual 307614.
5.Lubricate bearing housing after every 100 hours of operation. Remove front cover. Apply several drops of SAE 10
CAUTION
To prevent pump corrosion, and to reduce the chance of fluid freezing in the pump 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.Flush sprayer at end of each work day and fill it with mineral spirits to help prevent pump corrosion and freezing. See page 12.
7.For very short shutoff periods, leave suction hose in paint, relieve pressure, and clean spray tip.
