When all the rings have been fitted to fill the stuffing box, fit the gland follower and tighten the gland nuts to level the gland spigot. Tighten up to finger tightness only, then turn nut by one or two thread, loose it back & again tighten up to finger tightness again. (when storage is anticipated the gland should be left slack.) DO NOT OVERTIGHTEN.
Run pump up to operating speed for 10 to 15 minutes. If there is no leakage, stop pump, and loosen gland further. Repeat until leakage occurs. The controlled leakage, essential for lubrications purpose, can then be obtained by running the pump and evenly tightening the gland nut in increments of two threads until approximately one drop every few seconds is obtained. Approximately 15 minutes should be left between successive adjustments.
