General Repair Instructions

Purging Air From the System

•Pressure test distribution blocks yearly or every 8000 hours. Replace seals and divider valves as necessary.

Before machine operation is resumed following mainte- nance or repair, manual system air purging must be per- formed.

There are several air purging procedures available depending upon the maintenance or repair procedure.

NOTE: Use only clean oil filtered to the SAE -recom- mended 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.
