5 However, the responsibility for safeoperation rests with those who use and maintainthese products. The following safety precautionsare offered as a guide which, if conscientiously fol-lowed, will minimize the possibility of accidentsthroughout the useful life of this COMPRESSOR should be operated only by thosewho have been trained and delegated to do so, andwho have read and understood this Operator sManual. Failure to follow the instructions, proce-dures and safety precautions in this manual can re-sult inaccidents andinjuries. Readthis manualpriorto the COMPRESSOR unless it is safe to NOTattempt tooperatethecompressor witha known unsafe condition. Tag the COMPRESSOR andrender it inoperative by disconnecting and lockingout all power at source or otherwise disabling itsprimemover, soothers whomay not know of the un-safe condition, cannot attempt to operate it until thecondition is , use and operate the COMPRESSOR only in fullcompliance with all pertinent regulations and all ap-plicable Federal, State, and Local codes, standardsand NOTmodify the COMPRESSOR and/or controls inany way except with written factory not specifically applicable to all types of com-pressors with all types of prime movers.

6 Most of theprecautionary statements contained herein are ap-plicable to most compressors and the concepts be-hind these statements are generally applicable PERSONAL PROTECTIVE EQUIPMENTP rior to installing or operating the COMPRESSOR , own-ers, employers and users should become familiarwith, and comply with, all applicable regulations andany applicable Federal, State and Local codes,standards, and regulations relative to personal pro-tective equipment, such as eye and face protectiveequipment, respiratory protective equipment,equipment intended to protect the extremities, pro-tective clothing, protective shields and barriers andelectrical protective equipment, as well as noise ex-posure administrative and/or engineering controlsand/or personal hearing protective PRESSURE anappropriateflow--limiting valvebetweenthe service air outlet and the shut--off (throttle)valve, either at the COMPRESSOR or at any other pointalong the air line, when an air hose exceeding 1/2 (13mm) inside diameter is to be connected to theshut--off (throttle)

9 Check the relief valve as recom-mended in the Maintenance Section of this manualor at a minimum of at least weekly to make sure it isnot blocked, clogged, obstructed or otherwise NOTchange the factory settingof there-lief the COMPRESSOR is installed in an enclosedarea, it is necessary to vent the relief valve to theoutside of the structure or to an area of FIRE AND EXPLOSIONWARNING!When installing a Base Load Transfer (BLT) Sys-tem, remove jumpers between 16--17 & 18--19(Dual Control Compressors) so the other com-pressor does not backfeed defeating the shut-down up spills of lubricant or other combustiblesubstances immediately, if such spills off thecompressor andallow it tocool.

10 Thenkeep sparks, flames and other sources of ignitionaway andDO NOTpermit smoking in the vicinitywhen checking or adding lubricant or when refillingair line anti--icer systems with NOTpermit fluids, including air line anti--icersystem antifreeze compound or fluid film to accu-mulate on, under, or around acoustical material, oron any external surfaces of the air COMPRESSOR or oninternal surfaces of the enclosure. Wipe down usingan aqueous INDUSTRIAL cleaner or steam--clean as re-quired. If necessary, remove acoustical material,clean all surfaces and thenreplace acoustical mate-rial. Any acoustical material with a protective cover-ing that has been torn or punctured should be re-placed immediately to prevent accumulation of liq-uids or fluid film within the solvents for cleaning and lock out all power at source priorto attempting any repairs or cleaning of the com-pressor or of the inside of the enclosure, if electrical wiring, including all terminals andpressureconnectors ingoodcondition.
