c. Replace the Oil Plug.

Cold Weather Operation

Premium quality 30-weight, non- detergent air compressor oil (sold separately) is recommended for use with this compressor. Start compressor in heated area if outdoor temperatures drop below 32° F. If this is not practical, drain out the old pump oil and use SAE 10W Non- detergent Air Compressor Oil in the pump crankcase instead whenever the compressor’s temperature will fall below 40°. Do not use multi- viscosity oil (such as 10W-30), they leave carbon deposits on pump components and lead to accelerated failure. Heavy operation may require heavier viscosity oil.

4.If uncertain which oil to use for this compressor, please call Harbor Freight Tools customer service at 1-800-444-3353 for assistance.

5.Change the compressor oil after the first hour of use to remove any debris.

WARNING! To prevent serious injury from burns: Do not add or change the oil while the compressor is in operation. Allow the compressor to cool before replacing oil.

General Operating

Instructions

Read the entire Important Safety Information section at the beginning of this manual including all text under subheadings therein before set up or use of this product.

1.Close the Drain Valve (66) by turning it clockwise.

2.Make sure all nuts and bolts are tight.

3.Check for oil leaks and check the oil level (See Checking the Oil).

4.Close the in-line Shutoff Valve between the compressor and the air hose.

5.Make sure the air tool’s throttle or switch is in the off position.

6.Connect the air tool to the air hose.

7.Plug the Air Compressor Power Cord into a grounded 120 V electrical outlet.

8.Open the in-line Shutoff Valve.

9.Turn the Power Lever ON.

10.Allow the Air Compressor to build up pressure until it cycles off.

Note: At the beginning of the day’s first use of the Air Compressor, check for air leaks by applying soapy water to connections while the Air Compressor is pumping and after pressure cut-out. Look for air bubbles. If air bubbles are present at connections, tighten connections. Do not use the air compressor unless all connections are air tight, the extra air leaking out will cause the compressor to operate too often, increasing wear on the compressor.

Note: As long as the Power Lever is ON, the operation of the Air Compressor is automatic, controlled by an internal pressure switch. The Compressor will turn on automatically when the air pressure drops to 95 PSI as indicated on the Tank Pressure Gauge (53),
