B: The direct pressure gauge (fig 5) indicates the pressure inside the main tank. The regulated pressure gauge (fig 5) indicates thepressure supplied to the air equipment.Should the pressure in the main tank exceed the pre-set maximum, the safety valve (fig 3) will activate. WARNING! For this reason DO NOT tamper with, or adjust, the pressure switch (fig 6) or safety valve (fig 3).5.7.7. The compressor is fitted with a trip reset button, located on the side of the connection box on top of the motor (fig 3). Should the tripactivate, leave for 1 minute before pressing the button to reset.For possible causes of trip activation see section 6 Troubleshooting.6. MAINTENANCEIn order to keep the compressor in good workingcondition, periodic maintenance is essential. WARNING! Before performing any maintenanceoperation, switch off the compressor, disconnectfrom electricity supply and release all air from thetank.IMPORTANT! Failure to carry out maintenancetasks may invalidate the warranty on your compressor.6.1. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 5 WORKING HOURS:A: Check that all bolts/nuts are tight, particularly those retaining the crank case and cylinder head.6.2. OPERATIONS TO BE CARRIED OUT AFTER THE FIRST 50 WORKING HOURS:B: Replace the lubricating oil.6.3. OPERATIONS TO BE CARRIED OUT DAILY:A: Drain condensation by opening the valve located under the tank (fig 7). Place a container under the valve and slowly open thevalve by turning counter clockwise.6.4. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURSNOTE: Or more frequently, if the compressor operates in a very dusty atmosphere.A: Check oil level and, if necessary, top up.B: Remove the filter elements (fig 4) and clean with compressed air (wear eye protection). DO NOT operate the compressorwithout the filters as foreign bodies or dust could seriously damage the pump.C: Check for oil leaks.6.5. OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:A: Replace the lubricating oil. For oil specifications see 6.7.Remove the filler cap (fig 3) then unscrew the drain plug (fig 3) and drain the oil into a suitable waste oil container.Drain when the compressor is hot so that oil drains rapidly and completely. Incline compressor to ensure complete drainage.Replace drain plug and refill through the oil filler aperture. DO NOT overfill. Replace filler cap.B: Check the automatic cut-out at maximum pressure and the automatic cut-in at 2bar below. WARNING! Never mix different oils and DO NOT use non-detergent/low quality oils as the compressor may be damaged. WARNING! Dispose of waste oil only in accordance with local authority requirements.6.6. OPERATIONS TO BE CARRIED OUT EVERY 500 HOURS:A: Replace air filter (figs 1 & 4).B: Check all tube fittings and electrical connections.6.7. OILRecommended oil for compressors, suitable for room temperatures ranging from +5°C to +25°C.SEALEY CPO or equivalent SAE 40 compressor oil. Room temperature below +5°C: SAE 20 compressor oil. IMPORTANT WARNING - Air contaminants taken into the compressor will affect optimum performance. Example: Body filler dustor paint overspray will clog the pump intake filter and may cause internal damage to pump/motor components. WARNING! Any parts damaged by any type of contamination will not be covered by warranty.6.8. Inspection of pressure tank both inside and out.Under the PRESSURE SYSTEMS SAFETY REGULATIONS 2000 it is the responsibility of the owner of the compressor to initiate asystem of inspection that both defines the frequency of the inspection and appoints a person who has specific responsibility forcarrying out the inspection.7. TROUBLESHOOTINGOriginal Language Version© Jack Sealey Limitedfig.7fig.8FAULT POSSIBLE CAUSE REMEDY1A) Pressure drop in the tank Air leaks at connections Run compressor to maximum pressure, switch off.Brush soap solution over connections and look forbubbles. Tighten connections showing leaks.If problem persists contact Authorised Service Agent1B) Pressure drop in the tank Air leaks from safety valve It should be replaced, unless leaking at a jointwhich can be sealed.1C) Pressure drop in the tank Air leaks from cylinder head gasket Check tightness of head bolts. If leak continuescontact authorised Service Agent2) Pressure switch valve leaks whencompressor is idleNon-return valve seal defective Empty the air tank. Remove the check valve cap,spring and seal. Clean the seal and its seat, or ifnecessary replace the seal (fig 8)3) Air leaks from tank body or tank welds Internal corrosion caused by infrequent tankdraining or non permitted modifications to tankTank could rupture or explode. Cannot be repairedDISCONTINUE USE IMMEDIATELY4A) Motor stops and will not restart Thermal cut out has operated Allow unit to cool for 30 minutes before restartingSAC3103B Issue 4 (3,4,5) 01/04/22 |
