corresponding to the outlet port and the line
connected to the secondary valve.
3. Attach a hand pump filled with clean, filtered
lubricant on the master divider valve that was
opened in step 2.
4. Operate the hand pump until air-free lubricant is
observed flowing steadily from the secondary valve
lube inlet connector.
5. Tighten the fitting at the secondary valve inlet while
the lubricant is still flowing.
6. Remove all of the indicators or indicator port plugs
from the secondary divider valve working sections.
7. Operate the hand pump again until air-free lubricant
flows out of all the secondary divider valve indicator
ports.

plugs in the secondary divider valve while the
lubricant is still flowing from the ports.
