310000000)<br />
IMPORTANT: Make sure to remove and neutralize<br />
chemicals from spray components before valve motor<br />
disassembly. Wear protective clothing, chemical<br />
resistant gloves and eye protection during repair.<br />
NOTE: There are limited replacement parts available<br />
for boom and agitation valve motor assemblies. Check<br />
your parts catalog for parts that are available.<br />
5. Apply silicone grease to seals on piston valve assembly.<br />
6. Position spring into valve motor housing. Use 3mm<br />
allen wrench to secure piston valve assembly to valve<br />
motor.<br />
7. Secure hosebarb to bottom of valve motor.<br />
Valve Motor Cover Removal (Fig. 34)<br />

2. Make sure that valve is closed. If valve is not closed,<br />
spring above piston valve will be under compression<br />
and may damage valve motor or piston valve during disassembly.<br />
End of piston valve will extend into bottom of<br />
valve motor housing when valve is closed. If necessary,<br />
reconnect motor to machine wire harness and close<br />
valve before removing piston valve.<br />
