1. SAFETY
1.1. ELECTRICAL SAFETY
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. You
must also read and understand the following instructions concerning electrical safety.
9Ensure that cables are always protected against short circuit and overload.
9Regularly inspect power supply cables and plugs for wear or damage and check all connections
to ensure that none are loose.
9Ensure that the voltage marked on the appliance matches the power supply to be
usedandthattheplugisttedwiththecorrectfuse-seefuseratingatright.
8DO NOT use worn or damaged cables, plugs or connectors. Have any faulty item repaired or
replaced immediately by a competent electrician.
9It is recommended that this device is wired directly to a fused isolator switch. If, however, a plug
istted,thefollowingapplies:
9Fit 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 restraint is tight.
1.1.1. SAC3203B is 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 connection 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.
1.1.2. 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.

5. OPERATION
WARNING! Ensure that you have read, and fully 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. Confirm that the mains voltage corresponds with the voltage shown on the compressor data plate.
5.3. 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 2), and should be in a position that allows good air circulation around the unit, 1000mm
nominal gap.
5.4. Before using the compressor check the oil level by referring to the oil sight glass (fig 3). 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 6.7.
5.5. To top up undo filler cap (fig 3), top up oil level to required level, then replace filler cap.
5.6. 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.
5.7. STARTING THE COMPRESSOR.
5.7.1. Yourcompressoristtedwithapush/pulltypeON/OFFbuttontoturnthecompressor“ON”pulltheON/OFFbuttonupwards.
Toturnthecompressor“OFF”pushtheON/OFFbuttondownwards(g3).
5.7.2. CheckthattheON/OFFbuttonisinthe“OFF”positionandtheregulatordial(fig 5) is closed (Zero ‘0’ bar).
5.7.3. Plug mains lead into mains supply and start the compressor pulling the ON/OFF button (fig 3) upwards.
5.7.4. Leave the compressor running with no air line or tools connected, and regulated pressure gauge (fig 5) 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 direct pressure gauge (fig 5). This may take in excess of 5
minutes. The compressor will now operate automatically.
The pressure switch (fig 6) 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.
5.7.5. Stop the compressor by pushing the ON/OFF button (g3)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:Aprotractedwhistle(about20-25seconds)whenthecompressorstartswithnopressureinthetank.
5.7.6. The output pressure is regulated by the pressure regulator (fig 5). Turn the pressure regulator dial clockwise to increase pressure and
counter-clockwisetoreduceit.
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.
