Mechanic I:

PHYSICAL DEMANDS Must possess mobility to work in and around a standard shop setting, to operate a motor vehicle and drive on surface streets; strength, stamina, and mobility to perform light to medium physical work, to work in confined spaces and around machines, to climb and descend ladders, and to operate varied hand and power tools, equipment, and machinery; vision to read printed materials and a computer screen; and hearing and speech to communicate in person and over the telephone or radio. The job involves fieldwork requiring frequent walking in operational areas to identify problems or hazards. Finger dexterity is needed to access, enter, and retrieve data using a computer keyboard or calculator and to operate above-mentioned tools and equipment. Positions in this classification bend, stoop, kneel, reach, and climb to perform work and inspect work sites. Employees must possess the ability to lift, carry, push, and pull materials and objects weighing up to 50 pounds, or heavier weights with the use of proper equipment or assistance. ENVIRONMENTAL ELEMENTS Employees primarily work in the centralized maintenance shop and occasionally in the field and are exposed to loud noise levels, vibration, confining workspace, chemicals, dust, paint fumes, mechanical and electrical hazards, grease, oils, solvents, machinery with extremely hot surfaces and moving parts, moving objects or other vehicles, as well as cold and hot temperatures, inclement weather conditions, and road hazards. Employees may interact with members of the public or with staff under emotionally stressful conditions while interpreting and enforcing departmental policies and procedures.
SUPERVISION RECEIVED AND EXERCISED
Receives immediate supervision from the Lead Mechanic or Equipment Shop Foreman. Exercises no direct supervision over staff.

DISTINGUISHING CHARACTERISTICS
This is the entry-level in the Mechanic series. Initially under supervision, incumbents perform simpler repairs and preventive maintenance, and learn to perform more complex and difficult repairs and maintenance. Positions at this level usually perform some to most of the duties required of the positions at the II level, but incumbents are not expected to function at the same skill level and usually exercise less independent discretion and judgment in matters related to work procedures and methods. Work is usually supervised or directed by higher level Mechanics while in progress and fits an established structure or pattern. Exceptions or changes in procedures are explained in detail as they arise. As more experience is gained, assignments become more varied and are performed with greater independence.
These positions in the Mechanic class series are flexibly staffed and positions at the higher Mechanic levels are normally filled by advancement from the lower Mechanic level; progression to the higher Mechanic levels is subject to (i) the incumbent meeting the minimum qualifications for the classification including any required certifications; (ii) satisfactory work performance; (iii) management affirmation that the incumbent is performing the full range of duties assigned to the class; and (iv) management approval for progression to the higher Mechanic level.

DISASTER SERVICE WORKER
In addition to our everyday duties, we have an added responsibility to help in a declared disaster. Under California law, all public employees are Disaster Service Workers and may be called upon in the event of a disaster. The roles and responsibilities for Disaster Service Workers are authorized by the California Emergency Services Act and are defined in the California Government Code 3100-3102; Labor Code 3211.92(b).

SUPERVISION RECEIVED AND EXERCISED
Receives general supervision from the Lead Mechanic or Equipment Shop Foreman. Exercises no direct supervision over sta?, but may occasionally direct lower-level Mechanics in the performance of their duties.

DISTINGUISHING CHARACTERISTICS
This is the ?rst journey-level in the Mechanic classi?cation series, responsible for performing the a greater range of mechanical, electrical, hydraulic, pneumatic, gasoline, and diesel repair and maintenance required for County vehicles, and equipment. Incumbents are expected to more work independently and exercise judgment and initiative. Positions at this level receive only general instruction or assistance as new or unusual situations arise and are expected to become fully aware of the operating procedures and policies of the work unit. Positions at this level are distinguished from the Mechanic I by the performance of a greater range of duties as assigned, working more independently, and exercising judgment and initiative. This class is distinguished from the Mechanic III level in that the latter is expected to provide the full range of Mechanic duties with only minimal supervision. These positions in the Mechanic class series are ?exibly sta?ed and positions at the higher Mechanic levels are normally ?lled by advancement from the lower Mechanic level; progression to the higher Mechanic levels is subject to (i) the incumbent meeting the minimum quali?cations for the classi?cation including any required certi?cations; (ii) satisfactory work performance; (iii) management a?rmation that the incumbent is performing the full range of duties assigned to the class; and (iv) management approval for progression to the higher Mechanic level.
