Resumen del manual
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. G8297/G8298/G8299 Air Compressors -11 SECTION 5: 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. See Figure 7. 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. Fig 7. Checking oil level with dipstick. 2. Drain tanks of any condensation by opening the drain cocks on the bottom of both tanks. See Figure 8. 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. The tanks are best drained if the drain cocks are opened when the system is pressurized. Once water has stopped coming out, you can close the drain cocks. Fig 8. Typical location of drain cocks. 3. Clean off cylinder head cooling fins of any dirt which might hamper air flow. 4. Check for worn or damaged cords and plugs. 5. Check for any other condition that could hamper the safe operation of this machine. G8297/G8298/G8299 Air Compressors -12 After First 50 Hours After the first 50 working hours, or 30 days, whichever comes first, replace the oil in the motor with compressor oil (use ISO 100 or SAE 30W viscosity, non-detergent type). Also after this initial operation period, check to make sure that all the fittings are tight. Remove the air filter foam element (See Figure 9) and rinse it out in water. Allow it to dry and reinstall. Blow out any accumulated dirt between the cylinder cooling fins. Fig 9. Air filter cover and foam element. Weekly If the compressor is used on a regular daily basis, perform the following checks each week: 1. Rinse the air filter foam element in water. 2. Check for loose bolts or fittings. Every 300 Hours After every 300 hours or 3 months of regular operation, perform the following maintenance items: 1. Change compressor motor oil. 2. Rinse the air filter foam element in water. 3. Check for air leaks and correct as needed. 4. Clean cylinder head fins for proper cooling. 5. Check for loose bolts or fittings. G8297/G8298/G8299 Air Compressors -13 Pressure Limit Adjustment The compressor is delivered with pressure switch settings which turn the compressor pump off when it reaches a tank pressure of 135 PSI, and turn it back on when it reaches 105 PSI. Normally these settings should not require any adjustment. The hex nut on the top of the exposed switch is used to adjust the pressure limits. See Figure 11. Turn it clockwise to increase the pressure and counterclockwise to reduce. This will move both the maximum pressure shutoff point and the minimum pressure turn-on point simultaneously. These limits are not separately adjustable. Do not exceed a maximum cutoff pressure of 145 PSI. After adjusting, replace the cover and reconnect to the power source. In the event it becomes necessary to change, first make certain the compressor is disconnected from the power source. Then remove the black plastic cover below the On/Off switch. This is done by removing the rubber plug on top of the housing and inserting a Phillips® screwdriver. See Figure 10. Fig 10. Removing pressure switch cover. Adjusting Nut Fig 11. Adjusting nut on pressure switch. For the G8299, it is possible to control which motor comes on first by adjusting these pressure limits. The machine is set from the factory so the 2 HP pump comes on first to minimize amperage draw. If this is not acceptable, adjust the limits on the 2 HP higher, and set the limits on the 2.5 HP lower so they will operate in reverse of the factory setting. Do not remove the pressure switch cover with the machine plugged in to power. When the cover is off, the electrical connec...
