1. SAFETY
1.1. ELECTRICAL SAFETY.
WARNING! It is the user’s responsibility to read, understand and comply with the following:
You must check all electrical equipment and appliances to ensure they are safe before using. You must inspect power supply leads,
plugs and all electrical connections for wear and damage. You must ensure the risk of electric shock is minimised by the installation of
appropriate safety devices. An RCCB (Residual Current Circuit Breaker) should be incorporated in the main distribution board. We also
recommend that an RCD (Residual Current Device) is used with all electrical products. It is particularly important to use an RCD
together with portable products that are plugged into an electrical supply not protected by an RCCB. If in doubt consult a professional
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 all portable electrical appliances, if used on business premises,
to be tested by a qualified Electrician at least once a year, using a Portable Appliance Tester (PAT).
1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for the safe
condition of the appliance, and the safety of the appliance operator. If in any doubt about electrical safety,
contact a qualified Electrician.
1.1.3. Ensure the insulation on all cables and the product itself is safe before connecting
to the mains power supply. See 1.1.1. & 1.1.2. above and use a Portable Appliance Tester (PAT).
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply, leads, plugs and all electrical connections for wear and damage, especially
power connections, to ensure that none are loose.
IMPORTANT: Ensure the voltage marked on the product is the same as the power supply to be used, and check that
plugs are fitted with correct capacity fuse.
8DO NOT pull or carry the powered appliance by its power supply lead or output cables.
8DO NOT pull power plugs from sockets by the power cable.
8DO NOT use worn or damage leads, plugs or connections. Immediately replace or have repaired by a
qualified Electrician.
1.1.6. Model Nos SAC3153B and SAC3203B are supplied with a flying lead without a plug. Jack Sealey Limited recommend a 16 amp
protected supply. When connecting to a 16 amp protected supply, contact a qualified electrician to ensure connect to a suitably rated
supply. Provided a good 230V supply is available and the lead length is not increased from that supplied, the compressor may operate
from a 13 amp supply. This very much depends upon the quality of your power supply.
1.1.7. Wiring a BS 1363/A UK 3 Pin Plug.
WARNING! If in doubt contact a qualified electrician.
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) Ensure that the cable outer sheath extends inside the cable restraint and that the restraint is tight.
Sealey recommend that repairs are carried out by a qualied electrician. ATION

3. SPECIFICATION
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. Save the packing material for future transportation of the compressor. We recommend that you store the packing 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.
4.3. Confirm that the mains voltage corresponds with the voltage shown on the compressor data plate.
4.4. Assemble the wheels and swivel castor using the nuts, bolts and washers supplied (fig.8).
4.5. The compressor should be operated on a horizontal flat surface, or one that does not exceed 5° either transversely (tyres fully inflated to
1.5bar) or longitudinally with chocks (fig.3), and should be in a position that allows good air circulation around the unit (see 1000mm
nominal).
4.6. Before using the compressor check the oil level by referring to the oil sight glass (fig.4C). On a horizontal surface, if the oil level is not up
to the red centre mark it should be further topped up with recommended oil (See section 5.7). To top up unscrew plug (fig.4B).

4.7. Screw the back half of a filter unit into the port openings in each head as shown in (fig.4.A). Place a filter cover over each threaded rod
protruding from the back half of the filter and secure each with a wing nut. Refer also to (fig.7).
5. OPERATION
WARNING! Ensure that you have read, understood and apply Section 1 safety instructions.
5.1. 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 and could damage your compressor.
5.2. Take care when selecting tools for use with the compressor.
Air tool manufacturers normally express the volume of air 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.
5.3. STARTING THE COMPRESSOR.
5.3.1. Your compressor is tted with a push/pull type on/o󰀨 switch
to turn the compressor “on” pull the switch knob upwards.
To turn the compressor “o󰀨” push the knob downwards. (g.5.1)
5.3.2. Check that the on/o󰀨 switch is in the “o󰀨” position and the regulator
tap (fig.5.2) is closed (Zero ‘0’ bar).
5.3.3. Plug mains lead into mains supply and start the compressor pulling the
switch knob (fig.5.1) upwards.
5.3.4. Leave the compressor running with no air line or tools connected, and
regulator (fig.5.3) set to maximum pressure (fully clockwise). Make sure
that the pressure in the tank rises and that the compressor stops
automatically when the maximum is reached. This value is written on the
specification plate and shown on the gauge (fig.5.4). This may take in
excess of 5 minutes. The compressor will now operate automatically.
The pressure switch (fig.5.1) 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.
5.3.5. Stop the compressor by pushing the switch knob (g.5.1) downwards. The
compressed air inside the compressor head will flow out via the air line
tube situated beneath the switch housing. Restart is made easier and
prevents the motor from being damaged. DO 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.

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.
5.3.6. The output pressure is regulated by the pressure regulator (fig.5.2). Turn the knob clockwise to increase pressure and counter-clockwise
to reduce it. The knob can be locked at any required setting by tightening the locking ring (fig.5.5) up against the underside of the knob.
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 gauge (fig.5.4) indicates the pressure inside the main tank. The gauge (fig.5.3) indicates the pressure supplied to the air
equipment. Should the pressure in the main tank exceed the pre-set switch (fig.5.1) maximum, the safety valve (fig.5.6) will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the switch or safety valve.
5.3.7. The compressor is fitted with a reset trip, located in the connection box on top of the motor. The reset button is on the side of the box (fig.2).
Should the trip activate, leave for 1 minute before pressing the button to reset. For possible causes of trip activation and remedies see
section 6 Troubleshooting.
6. MAINTENANCE
In order to keep the compressor in good working condition, periodic maintenance is essential.
WARNING! Before performing any maintenance operation, switch o󰀨 the compressor, disconnect from electricity supply and
release all air from the tank.
IMPORTANT! Failure to carry out maintenance tasks 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 - see para 5.5.
6.3. OPERATIONS TO BE CARRIED OUT DAILY:
a) Drain condensation by opening the valve located under the tank (g.6). Place a container under the valve and slowly open the valve
by turning counterclockwise.
6.4. OPERATIONS TO BE CARRIED OUT EVERY 100 HOURS (or more frequently, if the compressor operates in a very dusty
atmosphere).
a) Check oil level and, if necessary, top up.
b) Remove the lter elements (See g.7) and clean with compressed air (wear eye protection). DO NOT operate the compressor
without the lters 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 specications see 5.7.
Remove the oil ller plug (see g.4.B) then unscrew oil drain plug (see g.4) and drain the oil into a container.
Drain when the compressor is hot so that oil drains rapidly and completely. Incline compressor to ensure complete drainage.
Replace oil drain plug and rell through the oil ller aperture. DO NOT overll. Replace oil ller plug.
b) Check the automatic cut-out at max. pressure and the automatic cut-in at 2bar below.
WARNING! Never mix di󰀨erent 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 lter. (See g.7)
b) Check all tube ttings and electrical connections.
6.7. Recommended 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 a󰀨ect optimum performance. Example: Body ller dust or
paint overspray will clog the pump intake lter and may cause internal damage to pump/motor components. Please note that 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 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.
