Operating this equipment has the potential to cause eye injury and hearing loss. Always wear eye and ear protection when operating an air compressor. Be certain the safety protection you wear meet the appropriate standards of the American National Standards Institute (ANSI). For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section. Daily 1. Check the oil level! Use the sight glass on the crankcase to make sure the oil reservoir is at the correct level. 2. Check for worn or damaged cords and plugs. 3. Check for any other condition that could hamper the safe operation of this machine. 4. When finished using the air compressor, drain the condensation from the tank as instructed in Draining Tank on Page 16, and leave the drain valve open until the next use. Weekly 1. Blow dirt and dust off of the air filter (Figure 9), then re-install. Figure 9.Air filter foam element. 2. Check for loose bolts or fittings. 3. Clean off all dirt and dust from the cylinder head, motor, fan, air lines, exhaust pipe, couplers and frame. Dirt can lead to overheating. 4. Check air lines and connectors to make sure they are in good condition. 5. Pull the safety drain valve to make sure it is working properly (see Draining Tank on Page 16). Continued on next page TheaircompressorwillturnONautomatically when it is set on AUTO. When performing maintenance make sure the AUTO/OFF lever is in the OFF position,thecompressoris unplugged, and the air pressure has been bled out of the tank. Model G0464/G0465/G0467/G0468/G0470 Air Compressors -15 Monthly After the first 50 working hours or 30 days, perform the following maintenance: 1. Change the oil in the air compressor pump as described in Changing Oil on Page 19. Quarterly After every 300 working hours or 3 months, perform the following maintenance: 1. Change the oil in the air compressor pump as described in Changing Oil on Page 19. 2. Check for air leaks and correct as needed. Draining Tank Some water may accumulate in the tank depending on usage and humidity. Drain water from the tank daily to increase the lifespan of the compressor and air tools. To drain the tank: 1. Leave the tank pressurized and open the drain valve, shown in Figure 10, to drain the water out of the tank. Note: Draining the air from the tank can be extremely loud. Wear ear protection when draining the tank. Figure 10.Tank drain valve. Pressure Safety Valve The pressure safety valve prevents damage to the tank by releasing pressure when the tank reaches maximum capacity. To check the pressure safety valve: 1. Locate the pressure safety valve shown in Figure 11. Pressure Safety Valve Figure 11. Pressure safety valve. Releasing the safety valve can be extremely loud. Protect your hearing with ANSI approved ear protection. 2. Clean any dirt or dust from the pressure safety valve. 3. Pull the metal ring on top of the safety valve to ensure the valve will release air. The pressure safety valve must be replaced if it cannot be pulled, or if it leaks after releasing pressure. Note: The safety valve is preset to release air if the tank exceeds its maximum pressure. DO NOT try to adjust the safety valve pressure setting! -16-Model G0464/G0465/G0467/G0468/G0470 Air Compressors SECTION 6: SERVICE This section is provided for your convenience—it is not a substitute for the Grizzly Service Department. If you need help troubleshooting, replacing parts, or you are unsure of how to perform the procedures in this section, then feel free to call our Technical Support at (570) 546-9663. Troubleshooting Symptom Motor will not start. Motor fails to develop full power (output of motor decreases rapidly with decrease in voltage at motor terminals). Motor overheats and thermal overload turns motor OFF. Possible Cause Possible Solution 1. Motor will not start if tank is fully pressurized. 2. Wait for motor to cool. 3. Check power line for proper voltage. 4. Inspect all connections on motor for loose or shorted terminals or worn insulation. 5. Install correct fuses or circuit breakers. 6. Replace the pressure switch. 1. Reduce load on power line. 2. Increase wire sizes or reduce length of the circuit. 1. Clean cylinder fins and motor area. 2. Inspect and clean air filter. 3. Do not use air tools with CFM needs that exceed the compressor CFM rating. 4. Clean out motor to provide normal air circulation. 1. Tank already pressurized. 2. Thermal overload switch has tripped. 3. Low voltage. 4. Short circuit in motor or cord, or loose connections. 5. Incorrect fuses or circuit breakers in power line. 6. Pressure switch is bad. 1. Power line overloaded with lights, appliances, and other motors. 2. Undersized wires or circuits too long. 1. Cooling fins dirty. 2. Air filter clogged. 3. Compressor is running too long without a break. 4. Air circulation through the motor restricted. Model G0464/G0465/G0467/G0468/G0470 Air Compressors -17 Symptom Possible Cause Possible Solution...
