Check that no false alarm occurs. MAINTENANCE GIGASENSE II is designed to be maintenance free, and checking of the performance can usually be made in the normal operation before the cranes are operated. When the equipment is operated in severe environment, high temperature, high humidity etc, it is however recommended that ocular inspection inside and outside of all parts is done on a regular basis i.e. -
