4. ASSEMBLY
4.1. Remove compressor from packaging and inspect for any shortages or damage. If anything is found to be missing or damaged contact
your supplier.
4.2. Confirm that the mains voltage corresponds with the voltage shown on the compressor data plate.
4.3. The compressor should be installed on a flat surface, or one that does not exceed 10° either transversely or longitudinally, (see fig.1) and
should be in a position that allows good air circulation around the unit.
4.4. IMPORTANT! The compressor is supplied without oil in it. The oil is in a separate container. Remove the transit plug from the oil filler
aperture, pour oil into the aperture until it has reached the correct level on the sight glass (fig.2B). Fit the oil filler/breather supplied into
the aperture.
8DO NOT attempt to run the compressor until this has been done.
4.5. Ensure that the air vent in the oil filler/breather is free from debris. If the air vent is blocked, pressure can build up in the crankcase
causing damage to the compressor and possible personal injury.
4.6. Fit the air filter into the inlet port if required (fig.4).

5. TOOL SELECTION
IMPORTANT Take care when selecting tools for use with the compressor. Air tool manufacturers normally express the volume of
air required to operate a tool in cubic feet per minute (cfm). This refers to free air delivered by the compressor (‘air out’) which varies
according to the pressure setting. DO NOT confuse this with the compressor displacement which is the air taken in by the compressor
(‘air in’). ‘Air out’ is always less than ‘air in’ - due to losses within the compressor - and so it is important that, before choosing equipment,
you study the ‘Free Air Delivery’ figures shown in the Specification Chart.
6. OPERATION
WARNING! ENSURE THAT YOU HAVE READ, UNDERSTOOD AND APPLIED SECTION 1 SAFETY INSTRUCTIONS.
6.1. Make sure that the main switch (fig.3.1) is ‘OFF’ (down).
6.2. Check the oil level by looking through the sight glass (See fig.2B).
6.3. Ensure that the tank drain valve is closed (fig.5).
6.4. Close the outlet pressure regulator by turning the knob clockwise (fig.3.2).
6.5. Connect the air tool required to the compressor via an air line connected to the air outlet.
6.6. Plug the mains cable into the mains supply and start the compressor by pulling up the main switch.
6.7. Allow the pressure in the tank to rise to the maximum at which point the compressor will automatically cut out. Tank pressure is shown on
the larger gauge (fig.3.5).
6.8. Begin to gradually open the regulator by turning the knob until the small gauge registers the required operating pressure specified for the
tool to be used. Always adjust up to the required pressure rather than down from a higher pressure. The required setting, once achieved,
can be locked by screwing the locking ring (fig.3.3) up tight underneath the adjusting knob.
6.9. You can now begin to use the tool. The compressor will operate automatically cutting in and out as required to restore the air pressure
in the tank. The pressure switch (fig.3.7) stops the motor when the maximum tank pressure is reached and restarts it when pressure falls
below the minimum threshold - approximately 2bar (29psi) less than the maximum pressure.
NOTE: a) If the motor does not cut in and out, but runs continuously when using an air appliance, the capacity of the
compressor may be too small for the appliance.
b) The main gauge (fig.3.5) indicates the pressure inside the main tank, NOT the pressure supplied to the air
equipment, which is shown on the smaller gauge (fig.3.4). Should the pressure in the main tank exceed the pre-set
switch (fig.3.7) maximum, the safety valve (fig.3.6) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the switch or the safety valve.
When the compressor is not being used set the regulated pressure to zero so as to avoid damaging the pressure regulator.
6.10. To stop the compressor press down the main switch (fig.3.1). When the compressor stops there will be a whistling sound as compressed
air is vented from the compressor head.
8DO NOT, other than in an emergency, stop the compressor by switching off the mains power, or by pulling the plug out, as the pressure
relief will not then occur and motor damage may result upon restart.
6.11. When you have finished using the compressor unplug the unit from the mains power supply.
6.12. Set the outlet pressure on the regulator to zero.
6.13. Remove the air line and air tool.
6.14. The tank must now be drained. This will release the air left in the tank and drain away condensation that may have formed within the tank.
Choose a suitable location for this operation and/or make provision to collect the condensation. Wear ear and eye protection. Open
the tank drain valve (See fig.5) slowly allowing air and moisture to bleed from the tank. After bleeding close the drain valve to prevent
debris building up in the valve.
WARNING! Water that is allowed to remain in the tank during storage will corrode and weaken the air tank which could cause the tank to
rupture. To avoid serious injury drain the tank after each use or daily.
6.15. SAFETY FEATURES
6.15.1. Thermal cut out: If the unit overheats the thermal cut out will operate and shut the unit down. Allow the unit to cool down then press the
reset button, located just inside the pump cover (fig.7).

7. MAINTENANCE
WARNING! Before performing any maintenance operation, switch off the compressor, disconnect from electricity supply and release
all air from the tank. In order to keep the compressor in good working condition, periodical maintenance is essential.
7.1. AFTER THE FIRST 50 WORKING HOURS REPLACE THE LUBRICATING OIL - see Item 7.4.1
7.2. OPERATIONS TO BE CARRIED OUT DAILY:
7.2.1. Drain condensation, place a container under the valve and open the valve by turning anti-clockwise (fig.1). Retighten the valve.
7.2.2. Check that all nuts and bolts are tight, particularly those retaining the crankcase and cylinder head.
7.3. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS: (or more frequently, if the compressor operates in a very dusty atmosphere).
7.3.1. Check oil level and, if necessary, top it up.
7.3.2. Remove the air filter element by unscrewing the filter holder (fig.4) and prising open the holder. Clean it by blowing through with an
air line at low pressure, from the clean side. Alternatively, wash it in soapy water, rinse and dry. DO NOT operate the compressor
without the filter as foreign bodies or dust could seriously damage the pump.
7.3.3. Check for oil leaks.
7.4. OPERATIONS TO BE CARRIED OUT EVERY 200 HOURS:
7.4.1. Replace the lubricating oil. Remove the oil filler/breather and unscrew the drain bolt (fig.2B), drain the oil into a suitable container. Drain
when the compressor is hot so that the oil drains rapidly and completely. Incline the compressor to ensure complete drainage. Replace
the drain bolt and refill with fresh oil through the filler aperture. DO NOT overfill.
7.4.2. Replace oil filler/breather (fig.2).
7.5. RECOMMENDED OIL:
7.5.1. Suitable for room temperatures ranging from +5ºC to +25ºC: SEALEY CPO or equivalent SAE 40 compressor oil.
7.5.2. Room temperature below +5ºC: SAE 20 compressor oil.
WARNING! Never mix different oils and DO NOT use non-detergent/low quality oils as the compressor may be damaged.
7.5.3. Dispose of waste oil only in accordance with local authority requirements.
7.5.4. Check the automatic cut-out at maximum pressure and the automatic cut-in at 2 bar below that.
7.6. OPERATIONS TO BE CARRIED OUT EVERY 500 HOURS:
7.6.1. Replace air filter.
7.6.2. Check all tube fittings and electrical connections.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on your compressor.
WARNING - Air contaminants taken into the compressor will affect optimum performance. Example: Body ller dust or paint
overspray will clog the pump intake lter and may cause internal damage to pump/motor components.
NOTE: Any parts damaged by any type of contamination will not be covered by warranty.
7.7. INSPECTION OF PRESSURE TANK BOTH INSIDE AND OUT
7.7.1. Under the PRESSURE SYSTEMS SAFETY REGULATIONS 2000 it is the responsibility of the owner of the compressor to initiate a
system of inspection that both defines the frequency of the inspection and appoints a person who has specific responsibility for carrying
out the inspection.
