TM 5-3895-374-24-1 COMPRESSOR LUBRICATION OIL LEVEL Always operate the unit in a level position Prior to start-up, check the sight glass to ensure that the oil In the compressor pump Is at  the  required  level.  The  oil  level  should  reach  1/8"  above  the red line on the sight glass (see Fig 7). If the oil level is below the red line, remove the oil fill plug and pour oil through the oil  filler opening  until  the  sight  glass  shows  the  correct   level.   Do   not overfill   or   underfill,   too   much   or   too   little   oil   will   harm   the compressor. CAUTION: The oil level In the pump crankcase must be checked daily. BREAK-IN PERIOD The compressor pump Is shipped with break-in oil which should be changed after the first 8 hours of operation. Drain the oil from the  crankcase  by  removing  the  cap  (see  Fig  7).  Additional  oil changes should be done at the Intervals specified below. OIL TYPE The correct lubricant is essential to the proper operation of your 2-stage cast Iron compressor. One of two types of oil should be used, depending on whether the compressor is operated under a normal load, or under a light load. Compressor oil meeting the following specifications should be available from a local industrial lubricant supplier. CAUTION: Motor oils are not suitable for compressor use. Figure 7.  Checking Oil Level NORMALLY LOADED COMPRESSORS (Compressors in typical installations) Oil  Type:  When  the  compressor  is  operated  under  a normal load, the durability of the oil at high temperatures is extremely  important.  Use  only SLC1 (Part No. 018- 0051SP)  or  PGS  iii  (Part  No  018-0053SP)  compressor oil or a premium reciprocating compressor oil made from highly   refined   base   stocks   and   meeting   the   following specifications: Minimum Flash Point.........................249-C (480-F) Maximum Pour Point ............................. -6 7C (20F) Minimum Viscosity at 40C ....................................................  100cSt at 1 00C .................................................11 3 cSt at 100°F ................................................525 SUS at 2100F..................................................65 SUS Minimum Viscosity index .......................................95 Rust Protection, ASTM D665 A&B ....................Pass Maximum CCR . ...............................................020% Oil Changes: After the initial break-in period, all additional oil changes should be done at 250 working hour intervals. LIGHTLY LOADED COMPRESSORS (Compressors that run infrequently AND experience condensation) Oil Type: When experiencing condensation, the ability of the    oil    to    separate    (demulsify)    water    is    extremely important This allows the water to settle to the bottom of the crankcase Use ISO 100 (30W) or 150 (40W) R & O oil that passes the ASTM D1401 demulsibility test. Two compressor    oils     meeting     these     requirements     are Sanborn 30W (Part No 018-0018) and Sanborn 40W (Part No 018-0029). Condensation:  Water  condensing  in  the  crankcase  is normal  under  certain  humid  conditions  and  light  duty cycling.  This  water  must  be  removed  from  the  pump  to prevent  damage  Use  a  demulsifying  oil  that  meets  the specifications above, and drain the condensation at least twice a week. After draining the condensation, check the oil level and add oil as necessary. CAUTION:  A  rise  in  the  oil  level  and  a  milky  oil  color indicate    condensation    is    forming    in    the crankcase     This     condensation     must be drained immediately, or damage to the pump may occur. Oil  Changes:  When  experiencing  condensation/water  in the crankcase, a complete oil change should be done at 100   working   hour   intervals   after   the   initial   break-in period. 200-2009 (page 3-636)
