FIG. 7

Steps 1-6, refer to FIG. 7.

1.Install the line from the secondary divider valve to the lube point, but do not completely tighten the connection at the lube point.

2.Remove the performance indicator port plug or the performance indicator from the working valve sec- tion on the secondary divider valve assembly corre- sponding to the outlet port and the line connected to the lube point.

3.Attach a hand pump filled with clean, filtered lubri- cant to the port on the secondary divider valve that was opened in Step 2.

4.Operate the hand pump until air-free lubricant is observed flowing from the line at the lubrication point.

5.Tighten the fitting at the lubrication point while lubri- cant is still flowing.

6.Remove the hand pump and reinstall the perfor- mance indicator or indicator port plug removed in Step 2.

NOTE: If check valves were not installed at the lubrica- tion point, lubricant may continually drain out of the line when the secondary port is open. Therefore, when check valves are not used, the method for bleeding this line is to tighten the line at both ends and repeatedly cycle the secondary divider valve via hand pump opera- tion until lubricant, free of air, flows from the lubrication point
