75 Point Service Inspection

FW Power Guide

75 Point Service Inspection

At FW Power we are committed to providing only the highest quality equipment, which is why our used generators undergo a 75 point service inspection check and a full load test prior to despatch. Consider it to be like an MOT and test run but  in much more detail covering all aspects of the operation and function of the generator. These tests are all recorded, with every repair item and recommendation clearly detailed on the test sheets – a copy of which is given to the customer upon purchase.
