CLASS SPECIFICATION
MECHANIC TECHNICIAN I
DEFINITION OF DUTIES:
This is intermediate, developmental-level, skilled work involving the inspection,
preventive maintenance and repair of a wide variety of heavy duty vehicles and
mobile equipment (such as dump trucks, cement mixers, excavators, graders, loaders,
back-hoes, rollers, pavers, various types of tractors, trenchers, tow trucks,
street sweepers, etc.), transit vehicles, and/or fire/rescue apparatus as well
as portable firefighting and rescue equipment. Primary contacts are with crew/shift
to which an employee is assigned, providing and receiving information and instructions.
This class of work may entail some public service/assistance, but it is incidental
to the primary focus of the work performed.
An employee in this class, working under general supervision, is able to perform
most mechanical work, but would still require direction and development in areas
of diagnosis and particularly complex repair jobs. Employees will be responsible
for carrying out preventive maintenance tasks; determining causes of vehicle/equipment/apparatus
operating problems by tracing and locating defects; selecting and safely using
proper tools, equipment, devices, manuals, references, established procedures
and techniques; and making repairs to heavy mobile equipment/vehicles, transit
vehicles, and/or fire/rescue apparatus as well as portable firefighting and
rescue equipment. A Mechanic Technician I uses initiative in carrying out recurring
assignments independently without specific instruction, but refers deviations,
problems, and unfamiliar situations not covered by instructions to a supervisor
or more experienced Mechanic Technician. Operating and/or performance tests
are usually administered by supervisory personnel or a Senior Mechanic Technician.
Complexity of the work derives from work on gasoline and diesel engine vehicles
and equipment which include hydraulic, pneumatic, mechanical, electrical, electronic
and computer controlled utility systems, controls, and features, many of which
work in consonance with and are dependent upon each other for proper functioning.
An employee in this class will often be required to complete repair work started
by another employee. In performing work on recurring assignments, a Mechanic
Technician I maintains vehicles, equipment, and apparatus, and repairs defects
or malfunctions which are more readily diagnosed than on the most complex assignments.
Work is performed in accordance with technical manuals, illustrations, specifications,
diagrams, and schematics. The impact of properly performed work is the provision
of vehicles which are both operationally safe and capable of performing in the
manner for which they were designed. While positions of this class are non-supervisory,
employees periodically provide on-the-job training and instruction to less experienced
Mechanic Technician Trainees. Work is performed in all of the following settings:
a centralized vehicle maintenance facility, machine shop, highway maintenance
depot, on the road, at fire scenes, land fills, or wherever a break down occurs.
Repair work may be performed in any weather conditions. Employees work in tiring
and uncomfortable positions for long periods, and must continuously bend, reach,
stretch, lift, stoop, climb and crouch often on top of, in, and under vehicles
and engines in cramped and awkward positions. Performance of the work of the
class regularly involves exposure to loud noises, vibrations, dust, dirt and
grease. Employees perform physically strenuous work while standing, lying down,
or sitting; and pull, push, lift and carry items which weigh up to 100 pounds,
and occasionally in excess of 100 pounds. The work requires employees to push,
pull, turn, position and otherwise move parts, assemblies, components, equipment
and tools often near or immediately adjacent to running engines where employees
are exposed to compressed air, electrical current, belts, pulleys, fan blades
and sharp edges. Additional hazards include spring-loaded parts, lifts and presses
on wet/greasy floors, hot hydraulic fluids and oils, acetylene and oxygen cutting
torches near flammable substances, battery acid and cleaning solvents, and working
at heights of from ten to twenty feet above the ground or floor level. Performance
of the work of the class may occasionally expose employees to human/animal waste
and/or body fluids. These hazardous working conditions require employees to
strictly follow safety procedures and regularly employ safety equipment including
safety glasses, rubber and leather gloves, hearing protection, eye and face
shields, respiratory masks, and steel toe shoes. Despite these precautions,
employees regularly receive cuts, burns, bruises and strains as well as eye,
ear, nose, throat and skin irritations.
