VIII. SERVICE AND MAINTENANCE High Pressure In-line Filter STACK VALVES - The valves on the boom control stack valve are protected by a 90 Micron in-line sintered bronze filter (fig. 8.18). When the filter element is removed for cleaning, caution should be taken so the gasket is in the proper place FIG 8.18
when re-installing (fig. 8.19). Also, re-install filter paying attention to direction of flow so the end marked “OUT” is oriented correctly.
Solution Line Strainer To help maintain consistent application rates, check the solution line strainer (fig. 8.20) daily for blockage. To remove the strainer, close the tank shutoff valves. Clean the strainer screen FIG 8.19
as required. Be sure to wear the appropriate clothing while removing and cleaning the line strainer screen. Confirm the gasket is in place before re-installing the screen. Line strainers for the high pressure pumps are located under each solution tank. Remove and clean them in the same manner.
Air Conditioning System Dryer The A/C system receiver/dryer (fig. 8.21) should be replaced if the A/C loop is ever opened such as replacing a compressor FIG 8.20
