English Check pump oil level Change pump oil X 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++ * 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 synthetic blend non-detergent air compressor oil, change oil every 100 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: Risk of unsafe operation. Unit cycles automatically when power is on. When performing maintenance, you may be exposed to voltage sources, compressed air, or moving parts. Personal injuries can occur. Before performing any maintenance or repair, disconnect power source from the compressor and bleed off all air pressure. 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 condi- tions 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 (Fig. 1) 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. Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve. Checking Air Filter (Fig. 1) 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. A dirty air filter will not allow the compressor to operate at full capacity. Keep the air filter clean at all times. 1. Ensure Auto/Off switch (B) is in the OFF Position. 2. Allow unit to cool. 3. Remove the 3 phillips screws and washers from the pump head. 16
