SAFETY PRECAUTIONS
Test procedures recommended in this manual assume that the reader is fully conversant with electrical safety principles, and is familiar with the operation of the various test instruments. DO NOT attempt to work on live equipment if you are not qualified or experienced in this work. Before testing the generating set,read the generating set Installation Manual, and this Fault Finding Manual, and become familiar with it and the equipment.

TESTING "LIVE" EQUIPMENT
It is essential that all test instruments are regularly checked for safety, and any connection leads, probes, or clips, are checked to ensure that they are suitable for the voltage levels being tested. Never attempt to test a "LIVE" generator unlessthere is another competent person present who can switch off the power supply or shut down the engine in an emergency. Never expose "LIVE" connections unless you have created a safe working area around you. Make sure you have made all other persons in the immediate area fully aware of what you are doing.

SAFE AND EFFICIENT OPERATION CAN ONLY BE ACHIEVED IF THE EQUIPMENT IS CORRECTLY INSTALLED,OPERATED AND MAINTAINED.
Many accidents occur because of a failure to follow fundamental rules and precautions.

ELECTRICAL SHOCK CAN PERSONAL INJURY OR DEATH.
