Graco 312497P Prefilling Lubricant Distributor Lines, Filling Secondary-to-Lube Point Lines

Setup

Prefilling Lubricant Distributor Lines

Follow the following procedure exactly as written, in the order written.

NOTICE

•The initial startup and operation is the most critical operating period for a newly installed machine in terms of potential for being damaged by unre- moved/unfiltered lubricant contaminants and lack of adequate lubrication. Proper prefilling of lubrication system ensures that lubricant is immediately avail- able to every lube point during machine startup, protecting them from damage.

•Use only clean oil filtered to the SAE -recom- mended cleanliness level of ISO 18/14 (ISO Stan- dard 4406) when prefilling a system. The manufacturers of the machine tool and its compo- nent bearings should be consulted to ensure that the ISO 18/14 cleanliness level is adequate.

Filling Secondary-to-Lube Point Lines

Refer to FIG. 4. when performing this procedure

.

3.In order to verify when lubricant is flowing and has reached the end of the lube line, loosen the connec- tor 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 indica- tors into the ports on the front of the working sec- tion.

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.

NOTE: Do not replace any of the performance indica- tors or port plugs removed in Step 1 until the line-filling procedure described in Section 2 (Filling Master -to-Secondary Lube Lines) has been completed.

FIG. 4

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 lubri- cant to the indicator port closest to the first line to be filled that corresponds to the output port that is feed- ing the line to be filled.

HAND PUMP TI11099

FIG. 5

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 lubri- cant 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.
