Prefilling Lubricant Distributor Lines
Follow the following procedure exactly as written, in the order
written.
1. Filling Secondary-to-Lube Point Lines
Refer to FIG. 3. when performing this procedure
.
1. Remove port plugs or performance indicators from all of
the indicator ports on front of secondary divider valves.
2. Connect a hand pump filled with clean, filtered lubricant to
the indicator port closest to the first line to be filled that
corresponds to the output port that is feeding the line to
be filled.
3. In order to verify when lubricant is flowing and has
reached the end of the lube line, loosen the connector at
the lube point of the line that is to be filled.
4. Stroke the hand pump until air-free lubricant is observed
flowing from the end of the lube line.
5. Tighten the lube line connector at the lube point, but do
not replace the port plugs or performance indicators into
the ports on the front of the working section.
6. Repeat steps 1-5 for each of the other lube lines
connected to the other outlet ports in the secondary
divider valve assembly and for any other secondary
divider assemblies in the system.
2. Filling Master-to-Secondary Lube Lines
Refer to FIG. 4. when performing this procedure.
1. Remove the port plugs or performance indicators from all
the indicator ports on the front of the master divider valve.
2. Connect a hand pump filled with clean, filtered lubricant to
the indicator port closest to the lube output port that is
feeding the line to the secondary divider valve.
3. Stroke the hand pump to fill the line between the master
divider valve and secondary divider valve.
4. Continue to stroke the pump until the lubricant purges all
the air out of the internal passages of the secondary
divider valve and lubricant flows freely from all indicator
ports with no evidence of included air.
5. Reinstall the port plugs or performance indicators in their
respective positions in the secondary divider valve. Do not
replace the port plugs or performance indicators in the
master divider valve yet.
6. Repeat Steps 1-5 for each of the other lube lines between
the master divider valve and all other secondary divider
valves.
CAUTION
• The initial startup and operation is the most critical oper-
ating period for a newly installed machine in terms of
potential for being damaged by unremoved/unfiltered
lubricant contaminants and lack of adequate lubrication.
Proper prefilling of lubrication system ensures that lubri-
cant is immediately available to every lube point during
machine startup, protecting them from damage.
• Use only clean oil filtered to the SAE -recommended
cleanliness level of ISO 18/14 (ISO Standard 4406) when
prefilling a system. The manufacturers of the machine
tool and its component bearings should be consulted to
ensure that the ISO 18/14 cleanliness level is adequate.

described in Section 2 (Filling Master -to-Secondary
Lube Lines) has been completed.

Do not replace any of the performance indicators or port
plugs removed in Step 1 from the master divider valve
assembly until the air-purging procedure described in
Section 3 (Filling Master Divider Valve) has been com-
pleted.
