How one Operating and Testing the Air compressor Safety Valve? Operating the Air compressor Safety Valve:           Operate the safety valve by unscrewing the cap one or two turns and re-tighten it. Testing the Air compressor Safety Valve: Before removing the valve one must depressurize the compressor Valve can be tested and separate air line. If the valve does not open at the set pressure stamped on the valve, it must be replaced. Caution: No adjustments allowed Never run the compressor without safety valve Must wear goggles Must wear hand gloves

Problem solving of Air compressor Caution Warning Before start working on Air Compressor must be follow this caution Before carrying out any maintenance, repair work or adjustment, press the stop button, wait until the compressor has stopped, press the emergency stop button and switch off the voltage. Close the air outlet valve and lock it if necessary. Problem of Air Compressor Condition 1: Compressor starts running but does not load after delay time. Fault: 1.       Solenoid valve out of order 2.       Inlet valve stuck in closed position 3.       Leak in control air flexible 4.       Minimum pressure valve leaking when net is depressurized Remedy 1.       Replace solenoid valve 2.       Check the valve 3.       Replace leaking flexible 4.       Check the valve Problem of Air Compressor Condition 2: Compressor does not unload, safety valve blows Fault: 1.       Solenoid valve out of order 2.

Maintenance Procedure of Air dryer   Dryer Maintenance: One must follow safety precaution any types of maintenance of dryer machine   Air Dryer Safety precautions: 1.       Contact of Refrigerant with the skin will cause freezing. One must be worn gloves avoid this risk. If refrigerant contacted with skin, the skin should be rinsed with water. On no clothing account may clothing be removed. 2.       Always should be wear safety glasses. Because fluid refrigerant will also cause freezing of the eyes. 3.       Before starting work must check the area is ventilated. Because refrigerant is harmful. Do not inhale refrigerant vapours. Dryer Machine Refrigerant: hydrofluorocarbons (HFC) Be aware the internal elements such as the pipes can reach a temperature of 110 ˚C or 230 ˚ F. Therefore wait until the dryer has cooled down before removing the panels. Before starting any maintenance or repair works, switch off the voltage

Problem Solving of Air Dryer   How one solves the problem of Air Dryer? Condition 1: Pressure dew point too high Fault: 1.       Air inlet temperature too high. 2.       Ambient   temperature too high 3.       Shortage of refrigerant 4.       Refrigerant compressor does not run 5.       Evaporator pressure too high 6.       Condenser pressure too high. Remedy: 1.       Check and correct, if necessary must clean the after cooler of the compressor 2.       Check and correct if necessary draw cooling air via a duct from a cooler place or relocate the compressor 3.       Have circuit checked for leaks and recharged. 4.       Clean condenser 5.       Have hot gas bypass valve adjusted 6.       Clean condenser and clean the fan Condition 2: Condenser pressure too high or too low Fault: 1.       Fan control switch out of order 2.       Fan blades or fan motor out of order 3.       Ambient temperature too high 4

Driveshaft Maintenance: 1.       To service the driveshaft disconnect the negative battery cables, remove the top of guard and set aside. 2.       Rotate engine shaft manually so the U joint grease fittings are Accessible. 3.       Using a held grease gun with N.L.G.I. grade 1 or 2 grease position on grease fitting. Pump with grease until grease is visible at all four cap seals. 4.       Verify all driveshaft connecting bolts tight. 5.       Reinstall top of guard and connect negative cables.
