The operator of the compressor should be well aware that during use of the compressor the motor will start and stop under the influence of the rising or falling pressure in the tank. The motor will start without any warning. 2. The maximum and minimum pressures are factory set and the operator should not try to change them. 3. You can connect an accessory to either the direct outlet valve (4) and/or the regulated outlet valve (7). The regulated outlet is the one on the left when you face the front of the compressor. 4. The pressure of the regulated outlet [as shown on the regulated outlet pressure gauge (8)] can be changed by turning the regulating knob (6). Rotate the knob clockwise to increase pressure and anti-clockwise to decrease pressure. Note. To obtain the correct output reading on the regulated output gauge, the air must be flowing through the outlet. Note. If you do not allow the air to discharge while you are setting the regulator, the pressure as indicated on the regulated outlet gauge will be incorrect. This gauge ONLY indicates the correct pressure while air is being discharged from the outlet. The discharge air from the right hand (opposite) outlet (4) is not regulated and will discharge air at tank pressure. The gauge for this outlet (5) will show the correct pressure in the tank with or without the air being discharged. 5. On completion of the task, i.e. when you have finished using the compressor, or when you are leaving the compressor unattended, turn off the compressor in the following way: • Press down the on/off switch (3). • Wait for the pressurised air to bleed from the tank from the release valve under the pressure switch cover (2). Note. When you press the button down you should hear a short air discharge ( Approx 1/2 second) • Switch off the electrical power supply and remove the electrical plug. • Pull the ring on the safety valve (9) to ensure all the pressurised air is released from the tank, or open the drain cock to release the pressure from the tank. Warnings. 1. Never attempt to remove any part of the compressor whilst the tank is under pressure. The regulating valve should be adjusted and the gauge read with the outlet valve open and the air being discharged from the regulated outlet. To increase the air pressure, rotate the regulating valve clockwise. To decrease the pressure, rotate the regulating valve anti-clockwise. 2. Never attempt to remove any electrical component whilst the compressor is connected to the power supply. Switch off the power and remove the electrical plug. 3. Do not adjust the safety valve. 4. Do not use an electrical extension cable. 12 5. If the release valve under the pressure switch cover (2) fails to operate when the on/off button is pressed down, switch the power supply off and determine the nature of the fault. 6. Ensure that the lubricating oil is clean and that the oil level is maintained at the mid point of the red circle in the oil level glass (17).. Troubleshooting 7. Take care when discharging air from the tank, i.e. from the safety valve, the drain cock or the air outlet. Compressed air can be extremely dangerous. Take care the discharge air does not cause dust, stones or any other foreign particles to be blown through the air and that the air is discharged in a safe manner. Trouble Possible cause Suggested remedy Motor will not run, running too slow or becoming excessively hot 1. Power fault or supply voltage too low 2. Power cord too long or too thin 3. Faulty pressure switch 4. Faulty motor 5. Main compressor sticking/tight 1. Check the power supply 2. Use authorised service centre to replace the power cord 3. Use authorised service centre to repair or replace the switch 4. Use authorised service centre to repair or replace the motor 5. Use authorised service centre to repair or replace faulty parts. Main compressor sticking/tight 1. Moving parts damaged by heat due to insufficient lubrication 2. Moving parts damaged or blocked by foreign particle Use authorised service centre to check crankshaft, bearings, con rod, piston rings, etc and replace where necessary. Vibration or abnormal noise 1. Loose part 2. Foreign body in main compressor 3. Piston connecting with the valve seat 4. Moving parts excessively worn 1. Use authorised service centre to check and repair if necessary 2. Use authorised service centre to check and clean if necessary 3. Use authorised service centre to increase size of gasket 4. Use authorised service centre to repair or replace 13 Insufficient pressure or decreased outlet capacity 1. Motor running too slow 2. Dirty air filter cartridge 3. Leaking safety valve 4. Leaking pipe 5. Damaged gasket 6. Damaged or carbon coated valve seat 7. Damaged piston ring or cylinder 1. Use authorised service centre to check and repair if necessary 2. Clean or replace the filter cartridge 3 – 7. Use authorised service centre to check and repair if necessary Excessive oil consumption 1. Oil level too high 2. Hole in oil filling ca...
