Thank you for purchasing a Sealey product. Manufactured to a high standard this product will, if used according to these instructions
and properly maintained, give you years of trouble free performance.
 WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:
You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and any other connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also recommend that a Residual Current Device (RCD) is used. It is particularly important to use an RCD with portable products that are plugged into a supply which is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual Current Device by contacting your Sealey dealer.
You must also read and understand the following instructions concerning electrical safety.
1.1.1.The Electricity at Work Act 1989 requires that all portable electrical appliances, if used on business premises, are tested by a qualified electrician, using a Portable Appliance Tester (PAT), at least once a year.
1.1.2.The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe condition of those appliances and the safety of the appliance operators. If in any doubt about electrical safety, contact a qualified electrician.
1.1.3.Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply. See 1.1.1. and 1.1.2. and use a Portable Appliance Tester.
1.1.4.Ensure that cables are always protected against short circuit and overload.
Yellow & Green
1.1.5.Regularly inspect power supply cables and plugs for wear or damage and check all Earth Wire
connections to ensure that none are loose.
1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply
to be used and that the plug is fitted with the correct fuse - see fuse rating at right.
1.1.7. DO NOT pull or carry the appliance by the power cable.
1.1.8. DO NOT pull the plug from the socket by the cable.
1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty
item repaired or replaced by a qualified electrician. When a BS 1363/A UK 3 pin plug is Cable
damaged, cut the cable just above the plug and dispose of the plug safely.
Fit a new plug according to the following instructions (UK only).
a)Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.
b)Connect the BROWN live wire to the live terminal ‘L’.
c)Connect the BLUE neutral wire to the neutral terminal ‘N’.
d)After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable outer insulation extends beyond the cable restraint and that the restraint is tight.
Double insulated products, which are always marked with this symbol , are fitted with live (brown) and neutral (blue) wires only.
To rewire, connect the wires as indicated above - DO NOT connect either wire to the earth terminal.
1.1.10. Products which require more than 13 amps are supplied without a plug. In this case you must contact a qualified electrician to ensure that a suitably rated supply is available. We recommend that you discuss the installation of an industrial round pin plug and socket with your electrician.
1.1.11. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance plugged into it will be protected. The cable core section is important and should be at least 1.5mm², but to be absolutely sure that the capacity of the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use of 2.5mm² section cable.
Familiarise yourself with the application and limitations of the compressor.
Ensure the compressor is in good order and condition before use. If in any doubt do not use the unit and contact an electrician/service agent.

3.1.Remove compressor from packaging and inspect for any shortages or damage. If anything is found to be missing or damaged contact your supplier.
3.2.Save the packing material for future transportation of the compressor. We recommend that the packing is stored in a safe location, at least for the period of the guarantee. Then, if necessary, it will be easier to send the compressor to the service centre.
3.3.Confirm that the mains voltage corresponds with the voltage shown on the compressor data plate.
3.4.SAC05030 - Fit the main wheels (fig.1.A) and two rubber feet (fig.1.B) to the main frame using the nuts, bolts and washers supplied.
SAC10030 - Fit the main wheels (fig.1.D) and small wheel (fig.1.E) to the main frame using the nuts, bolts and washers supplied.
3.5.The compressor should be installed on a flat, firm surface, or one that does not exceed 15° either transversely or longitudinally, and should be in a position that allows good air circulation around the unit.
The compressor is shipped with oil in the pump, but the level needs checking before starting the unit for the first time. Check the oil level by referring to the oil sight glass (fig.2.C). If the oil level is not up to the red centre mark, it should be topped up. Remove the plastic transit plug from the oil filler hole and if required, pour in the recommended oil. (See section 5.6). Screw the filler/breather cap supplied into the aperture as shown (fig.2.B).
3.7.Screw the back half of a filter unit into the downward facing port openings in each head as shown in fig.2.A. Place a filter cover over each threaded rod protruding from the back half of the filter and secure each with a wing nut and washer. Refer also to fig.4.
4. Operation
4.1. WARNING! Ensure that you have read, understood and apply Section 1 safety instructions.
IMPORTANT. The use of extension leads to connect this compressor to the mains is not recommended as the resulting voltage drop reduces motor, and therefore pump, performance.
4.2. 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 .

4.3.1.The compressor is fitted with a push/pull type of ON/OFF switch (fig.3.A).
To turn the compressor ‘ON’ pull the switch knob upwards. To turn the compressor ‘OFF’ push the switch knob downwards.
4.3.2.Check that the ON/OFF switch is in the “OFF” position and the regulator tap (fig.3.C) is closed (Zero ‘0’ bar, Anti-clockwise).
4.3.3. Plug mains lead into mains supply and start the compressor by pulling the ON/OFF switch knob upwards.
4.3.4.Leave the compressor running with the regulator tap (fig.3.C) set to maximum pressure. Make sure that the pressure in the tank rises and that the compressor stops automatically when the maximum pressure value allowed - written on the specification plate and shown on the gauge (fig.3.G) - is achieved. The compressor will now operate automatically. The pressure switch (fig.3.B) stops the motor when the maximum tank pressure is reached, and will restart it when pressure falls below the minimum threshold - approx. 2 bar (29psi) less than the maximum pressure.
4.3.5.Stop the compressor by pushing the switch knob downwards (fig.3.A). The compressed air inside the compressor head will flow out, making the restart easier and preventing the motor from being damaged.
DO NOT, other than in an emergency, stop the compressor by switching off the mains socket, or by pulling the plug out of the socket, as the pressure relief will not then occur and motor damage may result upon restart.
When the compressor runs correctly and is stopped correctly there will be:
(a) a whistle of compressed air when the motor stops,
(b) a protracted whistle (about 20-25 seconds) when the compressor starts with no pressure in the tank.
4.3.6.The output pressure is regulated by the pressure regulator tap (fig.3.C). Turn the tap clockwise to increase pressure and anti-clockwise to reduce it. The tap can be locked at any required setting by tightening the locking ring (fig.3.D) up against the underside of the tap. To determine the correct working pressure for any piece of equipment check the corresponding manual. When the compressor is not being used, set the regulated pressure to zero so as to avoid damaging the pressure reducer.
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 equipment or tool.
b)The larger gauge (fig.3.G) indicates the pressure inside the main tank. The smaller gauge (fig.3.F) indicates the pressure supplied to the air equipment. Should the pressure in the main tank exceed the pre-set switch (fig.3.B) maximum, the safety valve (fig.3.H) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the pre-set switch or safety valve (fig.3.B&H).
4.3.7.The compressor is fitted with an overload switch, and a reset trip button located in the connection box on top of the motor (see fig.1.C & fig.7). Should the overload switch activate, switch the compressor off and leave for a few minutes before pressing the trip reset button to reset, and then re-start the compressor. For possible causes of overload switch activation and remedies, see Section 6.
5. Maintenance
In order to keep the compressor in good working condition, periodic maintenance is essential.
WARNING! Before performing any maintenance operation, switch off the compressor, disconnect from electrical supply and release all air from the tank.
IMPORTANT! Failure to carry out maintenance tasks may invalidate the warranty on your compressor.
5.1. Operations to be carried out after the first 5 working hours:
a) Check that all nuts/bolts are tight, particularly those retaining the crankcase and cylinder heads.
5.2. Operations to be carried out after the first 100 working hours:
a) Replace the lubricating oil (see 5.6. below).
Operations to be carried out daily:
a) Drain condensation by opening the valve located under the tank (fig.5). Place a container under the valve to collect any condensation, as it may contain residual oil.
Close valve after draining condensation and dispose of it safely.
b) Regularly clean dirt and dust away from the safety devices with a clean cloth or blowing with low pressure compressed air. Generally keep the compressor clean.
5.4. Operations to be carried out every 100 hours:
(or more frequently, if the compressor operates in a very dusty atmosphere)
a) Check oil level, top up if necessary.
b) Remove the filter elements (fig.4). Turn off the compressor and using stored air from it's tank, clean the filters with compressed air. (Wear eye protection and DO NOT direct air towards the body or hands). DO NOT operate the compressor without the filters as foreign bodies or dust could seriously damage the pump. Replace the filter elements.
c) Check for oil leaks.
5.5. Operations to be carried out every 200 hours:
a) Check the automatic cut-out at maximum pressure, and the automatic cut-in at 2 bar below maximum pressure.
b) Replace air filters (See 5.4).
5.6. Operations to be carried out every 400 hours:
a) Replace the lubricating oil. For oil specifications see below.
Remove the oil filler/breather plug (fig.2.B) then unscrew oil sight glass (fig.2.C). Drain oil into a suitable container. Drain when the compressor is hot if possible, so that the oil drains rapidly and completely. Incline compressor to fig.5
ensure complete drainage. Replace oil sight glass and refill with fresh oil through the.oil filler/breather aperture. Do not overfill. Replace oil filler/breather plug.
WARNING!Never mix different oils and do not use non-detergent/low quality oils, as the compressor may be damaged.
Recommended oils: Recommended oil for compressors, suitable for temperatures ranging
from +5°C to +25°C: SEALEY CPO or equivalent SAE 40 compressor oil.
WARNING! Dispose of waste oil only in accordance with local authority requirements.
b) Check all tube fittings and electrical connections.
c) Inspect pressure tank inside and out for damage or corrosion.
