Troubleshooting and Maintenance Guide for the Hyundai HY140200PES Petrol Belt Driven Air Compressor

Troubleshooting:

Maintenance:

WARNING: Service and maintenance must be performed by an authorised agent. DO NOT tamper with or attempt to adjust the pressure switch or safety valve. Before moving or carrying out any maintenance on the compressor, make sure that the ignition switch is OFF, the air tank pressure has been vented and that the compressor has been allowed to cool down for a period of time.

Failure to carry out maintenance tasks may invalidate the warranty on your compressor. In order to keep the compressor in good working condition, periodic maintenance is essential.

Operations to be carried out after the first 60 hours of use:

• Check that all nuts and bolts are tight, particularly those retaining the crankcase and cylinder head.
• Replace the lubricating oil.

Operations to be carried out daily:

• Drain condensation by opening the valve located under the tank.

• Check the pump oil level.
• Check the engine oil level.

• Check all guards and covers are secure.
• Check for fuel and oil leaks.
• Check for air leaks.
• Check for unusual noises or vibrations.

Operations to be carried out weekly (or more frequently in dusty environments):

• Remove the air filter element by undoing the screw and removing the filter cover.

• Inspect the air filter and if worn or damaged, replace immediately. Clean the air filter by blowing through from the inside to the outside with a low pressure airline.
• Reinstall the air filter, cover and screw. DO NOT operate the compressor without an air filter as foreign bodies or dust could damage the pump and will invalidate the warranty.
• Clean the compressor. DO NOT use a pressure washer or hose pipe to clean the compressor as water could penetrate critical components and cause machine failure.
• Check that the relief valve vents pump output and reduces engine speed when maximum pressure is reached.
• Check that the compressor restarts pressure build up automatically at 2 bar below the maximum pressure.

Operations to be carried out monthly:

• Check belt tension.
• A weight of 3 kg applied at the belt mid-point should give a deflection of approximately 10 mm.
• If adjustment is required, maintain the alignment of the two pulleys. Adjust by repositioning the engine using the screw adjuster.

Operations to be carried out every 100 hours:

• Change the air filter element.
• Replace the pump lubricating oil with an oil suitable for temperatures ranging from -5°C to 45°C, viscosity Type 68 compressor oil.
• Drain the oil when it is warm, not hot, as this will allow the oil to drain more effectively.
• Place a suitable container under the drain plug and remove the drain plug.
• Once all the oil has drained, replace the drain plug and refill with new oil to the correct level.
• Replace the engine oil with semi-synthetic SAE 15W40 engine oil.
• Drain the oil when it is warm, not hot, as this allows the oil to drain more effectively.
• Place a suitable container under the drain plug and remove the drain plug.
• Once all the oil has drained, replace the drain plug and refill with new oil to the correct level.
• Check all tube fittings and electrical connections.
• Inspect the pressure tank inside and out for damage or corrosion.
