English 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. 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 2 wing nuts (R). RS T 4. Remove the outer metal covers (S). 5. Check the filter elements (T) if they are dirty or filled with paint, replace them. 6. Place the outer metal covers back over the filter elements. 7. Secure with the wing nuts. CAUTION: Risk of unsafe operation. Do not operate without air filter. Draining Air Tank (Fig. 3) WARNING: Risk of unsafe operation. Air tanks contain high pressure air. Keep face and other body parts away from outlet of drain. Use eye protection [ANSI Z87.1 (CAN/CSA Z94.3)] when draining as debris can be kicked up into face. WARNING: Risk from noise. Use ear protection (ANSI S12.6 (S3.19) as air flow noise is loud when draining. NOTE: All compressed air systems generate condensation that accumulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). This 16
