Harbor Freight Tools 67708 General Operating Instructions, Compressor Area Set Up

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.

Compressor Area Set Up

1.Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to prevent injury.

2.Locate the Compressor on a flat level surface to ensure proper pump lubrication and to prevent damage to the unit. Keep at least 12” of space around the unit to allow air circulation.

3.Route the power cord from the compressor to the grounded wall outlet, along a safe path without creating a tripping hazard or exposing the power cord to possible damage.

General Operation

1.Close the Drain Valve (66).

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 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 Switch 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 Switch 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), and will turn off automatically when the air pressure reaches 125 PSI as indicated. IMPORTANT: The internal pressure switch is not user adjustable, do not make changes to the air pressure settings of the internal pressure switch. Any change to the automatic pressure levels may cause excess pressure to accumulate, causing a hazardous situation.

11.Adjust the Air Compressor’s Pressure Regulator (74) so that the air output is enough to properly power the tool, but the output will not exceed the tool’s maximum air pressure at any time. Turn the knob clockwise to increase the pressure and counter-clockwise to decrease pressure. Adjust the pressure gradually, while checking the air output gauge to set the pressure.

12.Use the air tool as needed.
