TM 10-4310-392-13&PThis technical manual is an authentication of the manufacturer's commercial literature and does notconform with the format and the content requirements normally associated with Army technicalmanuals. This technical manual does, however, contain all essential information required to operateand maintain the equipment.Approved for public release; distribution is unlimited.SUPPLEMENTARY INTRODUCTORY MATERIAL1-1. Maintenance Forms and Records.Department of the Army forms and procedures used for equipment maintenance will be those described by DA Pam 738750, The Army Maintenance Management System.1-2. Reporting Errors and Recommending Improvements.You can help improve this manual. If you find any mistakes or if you know of a way to improve the procedures, pleaselet us know. Mail your letters, DA Form 2028 (Recommended Changes to Publications and Blank Forms), or DA Form2028-2 located in the back of this manual, directly to: Commander, U.S. Army Troop Support Command, ATTN:AMSTR-MCTS, 4300 Goodfellow Blvd., St. Louis, MO 63120-1798. A reply will be furnished to you.1-3. Destruction of Army Material to Prevent Enemy Use.Refer to TM 750-244-3 for instructions covering the destruction of Army Material to prevent enemy use.1-4. Administrative Storage of Equipment.a. Placement of equipment in administrative storage should be for short periods of time when a shortage ofmaintenance effort exists. Items should be in mission readiness within 24 hours or within the time factors as determinedby the directing authority. During the storage period appropriate maintenance records will be kept.b. Before placing, equipment in administrative storage, current preventive maintenance checks and servicesshould be completed. Shortcomings and deficiencies should be corrected, and all modification work orders (MWO's)should be applied.c. Storage site selection. Inside storage is preferred for items selected for administrative storage. If insidestorage is not available, trucks, vans, conex containers and other containers may be used.i/(ii Blank)

Installation and operating instructionsRead all instructions carefully before starting the compressor.General InformationL Series compressors are belt driven two-cylinder, air-cooled, single-acting piston machines. LE or LEN designatessingle-stage and LT two-stage. The LEN are oil-less compressors delivering oil-free air. The LE's are available 2through 10 HP, the LT's 2 through 20 HP, the LEN's 5 and 712 HP.The LE and LEN compressors are built for effective working pressures of up to 120 psig, LT for pressures of 175 psig.The compressors are available as base mounted units, which consist of the compressor block, base, drive, and motor,and as complete tank-mounted units.Operation - LE Series and LEN SeriesAir is drawn through the intake filter, intake manifold and suction disks into the cylinders. The air is compressed, thendischarged through the delivery disks to the temperature reducer, where the heat of the compressed air is partlyremoved. From the temperature reducer the compressed air is discharged through the check valve into the tank.Operation - LT SeriesAir is drawn through the intake filter, intake manifold and into the low-pressure cylinder, where it is compressed, thendischarged through the delivery valve to the intercooler, where the heat from the first stage of compression is removed.The air then enters the high-pressure cylinder through the pulsation damper and the suction disk, where it is furthercompressed. It is then discharged through the delivery disk to the cooling caps of the HP cylinder head and from there tothe HP temperature reducer. It is then discharged through the check valve into the tank.Lubrication (not for LEN)L Series compressors shipped from the factory contain a PAO synthetic lubricant. The compressors may be identified bya yellow label at the oil filler plug stating the unit contains "Airlet Fluid".If not available, a good-quality motor oil (not multigrade) or diester synthetic lubricant may be used. See chart.Use only reputable brands of oil and once a brand has been adopted, keep to it. Never mix oils of different brands ortypes. The crankcase oil capacity of the various units is given in section 7.NOTES:The crankcase is connected to the air intake silencer or suction line through a breather valve. Faulty operation of thisvalve or clogging of the metered hole will result in too high a crankcase pressure and promote oil consumption.Always securely tighten the oil filler plug after adding oil.LUBRICATION LE/LT COMPRESSORSLUBRICANTAMBIENTTEMPERATUREMOTOR OIL MINERALMOTOR OIL .I.SERVICECOMPRESSORCHANGEINTERVAL5 F to 104 F5 F to 104 FSAE 10W20SAE 10W30SE/CC/ SE/CDSF/CDLE/LTLE/LT2000 HRS (1)2000 HRS (1)-15 F to 122 FISO VG 32SF/CDLE/LT2000 HRS (1)-15 F to 122 FISO VG 32SF/CDLE/LTANNUALLY-15 F to 104 FSAE 10W40SF/CDLE/LTANNUALLY(2)BRANDMobil 1NuodexAnderol 3032Chevron/GulfGSL-838A(3)NuodexAnderol 495MobilRarus 824NuodexAnderol 800Change interval shown (hours) or annually, whichever occurs first.Atlas Copco does not recommend the use of specific lubricants.
