Model H3370/H3371Air Compressors AIR CONTROL Delivered Pressure The tank pressure is displayed on the left pressure gauge, and the air to be delivered to the tool is displayed on the right pressure gauge shown in Figure 6. Figure 7. Air control knob. Note—The air tool that you attach to the air compressor should have a preferred PSI operating level. Set the pressure to be delivered to the tool according to the tools preferred level. Understand the duty cycle of the air compressor. Model H3370/H3371Air Compressors Air Release There are two ways to release air from the compressor tank other than through your regulator and the use of air tools: —The drain valve —The safety drain valve To release air by using the drain valve, you simply turn the release nut to allow air to flow out of the tank. The drain valve is shown in Figure 5. The drain valve is also used to drain condensation that builds up in the tank. The safety valve automatically releases pressure if the tank reaches 130 PSI. To manually release the air in the tank by using the safety drain valve: 1. Locate the safety drain valve on the tank. The drain valve is shown below in Figure 8. Figure 8. Safety drain valve. 2. Pull the metal ring on top of the safety valve to bleed pressure from the tank. Note—The ring is preset to release air if the tank exceeds its maximum pressure. DO NOT try to adjust the safety valves pressure setting! -9 Tank Pressure Regulator The pressure regulator has been factory set for the highest quality operating performance. The pressure regulator sets the turn off PSI setting for the air compressor tank. NOTICE The Model H3370/H3371 Air Compressors have been factory set to kick off at the proper PSI range. Only attempt to adjust the pressure regulator if your air compressor does not reach or pressurizes beyond the proper PSI level. -10 To adjust the pressure regulator: 1. Unplug the air compressor from the power supply. 2. Make sure the compressor switch is in the OFF position. 3. Drain the pressure from the tank. 4. 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. 5. Turn the pressure adjustment screw (Figure 9) a half turn clockwise to increase the tank pressure and a half turn counter-clockwise to decrease the pressure. 6. Connect the compressor to the power supply and start compressor. 7. If the PSI level still needs adjustment, repeat steps 1 through 6. 8. Replace the cover when the proper adjustments have been made. Figure 9. Pressure Regulator Model H3370/H3371Air Compressors CONNECTING TOOLS To connect air tools to your air compressor: 1. Make sure the compressor model you use has a 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.) 2. The compressor should put out a higher CFM than the tool requires. If you are connecting multiple tools that will be used simultaneously, then the CFM for each tool should be added together and compared to the compressor output value. 3. Connect the tool, using a good quality air line with an adequate length to reach from the compressor to the point of use. Note—Quick-connect couplers, shown in Figure 10, are a good option for fast and sure connection of tools and air hoses. Figure 10. Quick connect couplers These couplers are included with the air compressor. Make certain the air hose will not be placed in a position where it can become constricted or cut by a sharp object. Note—Running over a hose with heavy vehicles may not cause an immediate leak, but it will shorten the life of the hose. Model H3370/H3371Air Compressors 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. Always disconnect air hose from tools whenever not in use or while servicing! During maintenance, a tool connected to air may operate accidentally, causing serious per- sonal injury! The Model H3370/H3371 Air Compressors are specifically designed for air tool operation. DO NOT MODIFY OR USE THIS MACHINE FOR ANY OTHER PUR- POSE. Modifications or improper use of this tool will void the warran- ty. If you are confused about any aspect of this machine, DO NOT use it until you have answered all your questions. Serious personal injury may occur. -11 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 followi...
