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. 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 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 use a
Portable Appliance Tester.
1.1.4. Ensure that cables are always protected against short circuit and overload.
1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure
that none is 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.
8 DO NOT pull or carry the appliance by the power cable.
8 DO NOT pull the plug from the socket by the cable.
8 DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty item repaired or
replaced by a qualified electrician.

5. OPERATION
WARNING! Ensure that you have read, understood and apply
Section 1 safety instructions.
IMPORTANT! Use of extension leads to connect these
compressors to the mains is not recommended as the
resulting voltage drop reduces motor and therefore pump
performance, and could damage the compressor.
NOTE: 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(‘airout’)whichvariesaccordingtothe
the pressure setting.
DO NOT confuse this with the compressor displacement
whichistheairtakeninbythecompressor(‘airin’).‘Airout’
isalwayslessthan‘airin’duetolosseswithin
the compressor.

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, as the pressure relief will not then operate and motor damage may result upon restart.
5.1.6. The motor of the compressor is fitted with a thermal breaker located in the housing on top of the motor. The manual resetting button is
located in the end of the housing as shown in fig.6. When the breaker is tripped, wait for a few minutes and then press the reset button.
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) indicates the pressure inside the main tank, NOT the pressure supplied to the air equipment.
Should the pressure in the main tank exceed the pre-set switch maximum, the safety valve will activate.
WARNING! For this reason DO NOT tamper with, or adjust, the switch or safety valve.
6. MAINTENANCE
6.1. In order to keep the compressor in good working condition, periodic maintenance is essential.
