Service Meter Hours

Operating and Maintenance Manual gives general guidelines for servicing based onservice meter hours. Talking with your machine’s operator can reveal many potential component problems. Service history indicates how frequently routine maintenance is performed. Indicates when a piece of equipment is operating at less than optimum efficiency. SOMA is a software that assesses customers operating and maintenance practices and provides component life estimates. 5
