Maintenance Worker
This is the entry level class in the Equipment Operator series. This class is distinguished from the journey level by the performance of the more routine tasks and duties assigned to positions within this series. Employees at this level are not expected to perform with the same independence of direction and judgment on matters allocated to the journey level. Since this class is typically used as a training class, employees may have only limited or no directly related work experience. Employees work under immediate supervision while learning job tasks.

Equipment Operator
This is the full journey level class within the Equipment Operator series. This class is distinguished from the Maintenance Worker by the assignment of the full range of duties. Employees at this level receive only occasional instruction or assistance as new or unusual situations arise and are fully aware of the operating procedures and policies within the work unit. Positions in this class are flexibly staffed and are normally filled by advancement from the entry level.

This class is distinguished from the Senior Equipment Operator in that the latter performs complex and difficult road maintenance, repair, traffic striping, tree trimming and removal, and street sign fabrication and installation activities requiring a high degree of skill and independent judgment, and exercises technical and functional supervision over crew members.
