Maintenance Chart Procedure Check safety valve Inspect air filter X X+ Drain air tank X Check pump oil level X Change pump oil X **+ Oil leak inspection X Inspect drive belt X Check drive belt tension X Check pulley/flywheel alignment X Check for unusual noise/vibration X Check for air leaks X* Clean compressor exterior X Remove tank from service X++ Engine See engine instruction manual. * To check for air leaks apply a solution of soapy water around joints. While compressor is pumping to pressure and after pressure cuts out, look for air bubbles to form. ** The pump oil must be changed after the first 20 hours or operation. Thereafter, when using full synthetic non-detergent air compressor oil, change oil every 200 hours of operation or once a year, whichever comes first. + Perform more frequent in dusty or humid conditions. ++ For more information, call 1-888-895-4549 . WARNING: To avoid personal injury, always shut off the gasoline engine and relieve all air pressure from the system before performing any service on the air compressor. To ensure efficient operation and longer life of the air compressor outfit, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to an outfit in a normal working environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications will depend upon the hours of operation and the working environment. Compressor outfits in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks. NOTE: See Operation section for the location of controls. Checking Safety Valve (refer to Fig. 1, pg. 2) WARNING: Hot surfaces. Risk of burn. Tubes, pump head, and surrounding parts are very hot, do not touch (see the Hot Surfaces identified in Fig. 2). Allow compressor to cool prior to servicing. WARNING: Risk of bursting. If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture or an explosion. WARNING: Risk from flying objects. Always wear certified safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields. 18
