English Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operatesfreely. If the valve is stuck or does not operate smoothly, it must be replaced with the same type of valve. Checking Air Filter 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 engine START/RUN/OFF switch (C) is in the OFF posi- tion. 2. Allow unit to cool. 3. Remove the wing nut (P). 4. Remove the outer metal cover (Q). 5. Remove element (R) from filter base. P 6. If element needs cleaning, blow out with air. Replace if needed. Purchase Q replacement parts from your local deal- er or authorized service center. Always R use identical replacement parts. 7. Place element back in filter base. 8. Place the outer metal cover back over the filter element. 9. Secure with the wing nut. CAUTION: Risk of unsafe operation. Do not operate without air filter. Draining Air Tank (refer to Fig. 3, pg. 17) 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 condensate contains lubricating oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations. 1. Ensure engine START/RUN/OFF switch (C) is in the OFF position. 2. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring. 3. Drain water from air tank by opening drain valve (counterclockwise) on bottom of tank. WARNING: Risk of bursting. Water will condense in the air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture. NOTICE: Risk of property damage. Drain water from air tank may contain oil and rust which can cause stains. 4. After the water has been drained, close the drain valve (clockwise). NOTE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled. 19
