Maintenance and Cleaning
General Valve Maintenance
Lubricate the Packing (E) on the valve every 200 hours by placing a few drops of mineral
oil or other light oil inside the Packing Nut (F).
The Packing Nut (F) will require occasional tightening as wear occurs in order to prevent
leaks through the Packing (E).
