These three procedures should always be per formed as a
complete group in the sequence listed in order to ensure
that every component in the system is completely filled with
lubricant prior to machine start-up.
CAUTION
Use only clean oil filtered to the SAE recommended
cleanliness level of ISO 18114
(ISO Standard 4406)
when prefil ling a system. The manufacturers of the
machine tool and its component bear ings should be
consulted to ensure that the ISO 18114 cleanliness level
is ade quate.
PREFILLING THE SYSTEM WITH LUBRICANT
Once the lubrication system installation has been completed,
it is necessary to prefill all of the lines (tubing/pipes/hoses)
and all of the divider valves before operation of the lubrication
system can be started. Proper adherence to the following
proce dures will help to reduce and alleviate machine start-up
problems caused by residual air in the lubrication system lines
and components during their installation process. Leaving
entrapped air in the lube lines could prevent lubricant from
gaining access to the lube points during the critical initial start-
up period. Proper prefilling of the lubrication system will insure
that lubricant is immediately available to every lube point upon
machine start up, protecting them from any potential damage.
In order to simplify prefilling, it is divided into three separate
procedures:
Filling the lines connecting the secondary di vider valves to

divider valve assembly and for any other secondary
divider assemblies in the system.
NOTE:
Do not replace any of the performance indicators or
port plugs removed in Step 1 until the line-filling procedure
described in Filling Master-to-Second ary Lube Lines has also
been completed.
Filling Secondary-to-Lube Point Lines
Refer to Figure 23 when performing this proce dure:
Remove the port plugs or performance indica tors from all

of the indicator ports on the front of the secondary divider
valves.
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.
In order to verify when the lubricant is flowing and has
