English Daily Weekly Monthly 1 year or 100 Hours See tank warning label Shut-down (Fig. 2) 1. Move Auto/Off switch to the OFF (O) position. NOTE: If finished using compressor, follow Steps 2 - 7. 2. Turn the regulator knob counterclockwise until fully closed. Ensure regulated pressure gauge reads 0 PSI (0 kPa). 3. Remove hose and accessory. WARNING: Risk of unsafe operation. Firmly grasp air hose in hand when installing or disconnecting to prevent hose whip. 4. Drain the air tank, see Draining Air Tank under Maintenance. Ensure air tank pressure gauge reads 0 PSI (0 kPa). WARNING: Risk of bursting. Drain air tank daily. Water will condense in air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture. 5. Allow the compressor to cool down. 6. Wipe air compressor clean and store in a safe, non-freezing area. 7. Unplug air compressor and wrap cord loosely around the handle. 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 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. MAINTENANCE 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++ * 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 of operation. Thereafter, when using full synthetic 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 . 16
