Many experienced mechanics have thousands of dollars invested in tools. Auto mechanics also use power tools such as pneumatic wrenches to remove bolts quickly. They may use machine tools such as grinding machines and lathes to rebuild brakes. Other tools include welding equipment, jacks, and hoists. Mechanics also use a growing variety of electronic service equipment, such as infrared engine analyzers and computerized diagnostic devices.
Employers often provide power tools, testing equipment, and uniforms.
Mechanics are sometimes exposed to hazards from power tools, electricity, and chemicals. Minor bruises, burns, and cuts are common. Some mechanics are members of labor unions. Wages vary according to training, experience and location. Entry level wages may be lower.
