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. Over/current Protection: The user has to make provision for the installation of the over-current protection of the power circuit.
1.2. Electrical disconnecting device: The user has to make provisions for the installation of the electrical disconnecting device of the power
circuit. The supply disconnection device is to be in accordance with EN 60204-1:2006.
1.2.1. 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.
1.2.2. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the power supply.
1.2.3. If the replacement of the supply cord is necessary, this has to be done by the manufacturer or his agent in order to avoid a safety hazard.
1.2.4. Ensure that cables are always protected against short circuit and overload.
1.2.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections to ensure that none are loose.
1.2.6. 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.
▲ DANGER! If the power cable for this equipment is damaged, it must be replaced by the manufacturer or its after-sales service or similarly
trained personnel to avoid danger.
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.
NOTE: If using a transformer to supply the compressor, it must be rated at a minimum of 2kVA to allow the compressor to run efficiently.
1.2.7. Power tool plugs must match the outlet. Never modify the plug in any way. DO NOT use any adaptor plugs with earthed (grounded) power
tools. Unmodified plugs and matching outlets will reduce risk of electric shock. Avoid body contact with earthed or grounded surfaces,
such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
8 DO NOT expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
8 DO NOT abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from the heat, oil, sharp
