Always wear safety glasses or goggles when operating equipment. Everyday glasses or reading glasses only have impact resistant lenses, they are not safety glasses. Be certain the safety glasses you wear meet the appropriate standards of the American National Standards Institute (ANSI). Operating this equipment has the potential for hearing damage to occur, especially if operated for a long period of time. Use ANSI (American National Standards Institute) approved ear muff or ear plugs when using this equipment. Always wear proper hearing protection, cotton balls or tissue paper in the ear canal do not provide adequate noise reduction. -8- G8694/G8695/G8889 Air Compressors Starting Make sure the compressor switch is in the OFF position (the red button on top of the control box should be in the fully depressed position, see Figure 3) before connecting to the power supply. Close the drain cock on the tank. Pull the switch to the ON position. On/Off Switch Output Gauge Fig 3. Start switch and gauges. Check the pressure gauge to see that the tank pressure gets up to approximately 110-115 PSI. Pressure Regulator The pressure gauge will indicate the amount of pressure that will be delivered from the tank. To adjust the delivery pressure, remove the black On/Off switch cover by removing the screw which is in the recess on the top of the cover. Pull the black cover up and set it aside. Turn the pressure adjustment screw (See Figure 4) clockwise to decrease pressure and counterclockwise to increase pressure. Replace the cover when the adjustment is complete. Figure 4. Pressure regulator. Always wear safety glasses and use extreme caution when working around compressed air. The force of the air stream can cause small bits of debris to become airborne and cause potential injury to the eyes or other parts of the body. Never let the full force of the air stream come in direct contact with the skin as it can cause abrasions or bruising. -9 Connecting Tools Air Control Valve Make sure the compressor model you use has sufficient cubic feet per minute (CFM) output for the air tool you plan to connect. Most air tools will have an air requirement stated in terms of a specific CFM at a specific pressure (PSI). Consult the chart below to determine the output of your compressor model. Model HP CFM @ 90 PSI Tank Cap. G8294 2.0 3.0 7 gal G8295 2.5 3.5 11 gal G8889 2.0 4.2 4 gal The compressor should put out a higher CFM than the tool requires. If connecting multiple tools which will be used simultaneously, then the CFM for each tool should be added together and compared to the compressor output value. Consideration should also be given to the type of usage. A nailer or staple gun uses air in short bursts and it is easier for the compressor to maintain pressure. A paint sprayer or grinder tends to use a more continuous stream of air as these tools are run for longer time periods. It is always better to oversize a compressor to allow for variation in the type of usage and the number of tools to be powered. Air tools being operated with insufficient air volume will not perform their function satisfactorily. Connect the tool using a good quality air line with an adequate length to reach from the compressor to the point of use. Quick-connect couplers are a good option for fast and sure connection of tools and air hoses. Make certain the air hose will not be placed in a position where it can become constricted or cut by a sharp object. Having a hose run over by heavy vehicles may not cause an immediate leak, but it will shorten the life of the hose. The air control valve lever is located just next to the On/Off switch near the air outlet fitting. When the lever is turned so it is in line with the fitting, the valve is OPEN. When it is at a 90° position relative to the fitting, the valve is CLOSED. (See Figure 5). The air outlet supplied is a brass barb fitting over which an air hose can be slipped. This will be suitable for low pressure uses. If you will be operating at higher pressure, or running air tools, you should replace this fitting with a quick connect coupler which you can find at your local hardware store.

Pull the metal ring to release the pressure. G8694/G8695/G8889 Air Compressors -10 MAINTENANCE Each Use Regular periodic maintenance on your Air Compressor will ensure its optimum performance. Make a habit of inspecting your compressor each time you use it. Check the following items: 1. Check oil level. 2. Drain tanks of any condensation by opening the drain cocks on the bottom of both tanks. See Figure 6. Depending upon the amount of use and the weather conditions, a certain amount of condensed water may be released. For longevity of the compressor seals and the air tools you connect, it is best to keep the tanks free of water. T...
