Review the Maintenance section on the preceding pages and perform scheduled maintenance as necessary. 2. Drain water from air tank. See To Drain Tank under Maintenance. 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. 3. Protect the electrical cord and air hose from damage (such as being stepped on or run over). Wind air hose loosely around the compressor handle. Wrap electrical cord onto the cord wrap as shown. 4. Store the air compressor in a clean and dry location. Cord Wrap SERVICE REPLACEMENT PARTS REPLACEMENT PARTS Use only identical replacement parts.

Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pressure, and allow the air compressor to cool. PROBLEM Excessive tank pressure - safety valve pops off. Air leaks at fittings. Air leaks in air tank or at air tank welds. Air leaks between head and valve plate. Air leak from safety valve. Knocking Noise. CAUSE Pressure switch does not shut off motor when compressor reaches "cut-out" pressure. CORRECTION Move On/Off lever to the "Off" position, if the outfit does not shut off contact a Trained Service Technician. Pressure switch "cutout" too high. Tube fittings are not tight enough.
