Tools and Equipment Fundamentals CH 6.1 Tools and Equipment Fundamentals

Introduction (1 of 2) Tools and equipment are very important to an efficient and effective shop operation. Provide means for work to be undertaken on vehicles Purchase, use, and maintenance is very important to overall performance of any shop.

Introduction (2 of 2) Always use tools and equipment the way they are designed to be used. Identify the most effective tools to do the task. Inspect the tool before using it. Use it correctly. Clean and inspect it after you use it. Store it in the correct location.

General Guidelines (1 of 8) Important to be trained on safe use More critical to have a safe attitude Safe attitude will help avoid accidents. Pay attention to safety and operation procedures. Work safe and stay safe. If tools are used incorrectly, you can potentially injure yourself and others. Always follow equipment and shop instructions. Use personal protective equipment (PPE).

General Guidelines (2 of 8) Safe handling and use of tools Must be safely handled and used to prevent injury and damage Always inspect prior to use and never use damaged tools. Check manufacturer and shop procedures or ask supervisor if uncertain about tools use. Inspect and clean when finished using them. Always return to correct storage location.

General Guidelines (3 of 8) Safe procedures for handling tools and equipment Some are heavy or awkward to use; seek assistance.

General Guidelines (4 of 8) Tool usage Extend our abilities to perform many tasks What tool can make the job easier, safer, or more efficient? Familiarity with tools increases productivity, quality, and effectiveness. Every tool is designed to be used in a certain way to do job safely. Select correct tools for task and use each as designed.

General Guidelines (5 of 8) Lockout Physically securing a broken, unsafe, or out-of-service tool so it cannot be used by a technician Tagout Affixing a label to equipment describing faults

General Guidelines (6 of 8) Tool Location Shop will usually have selection of tools for use. Technicians have selection of their own tools. Tools and their usage in automotive application Create a list of tools in tool chest. Identify their application. Look through shop’s tool storage areas and create list of tools found in each storage area.

General Guidelines (7 of 8) Standard and metric designations United States customary system (USCS) sizes or “standard” Metric sizes Identified by markings identifying size on tools or increments on a measuring tool

General Guidelines (8 of 8) To identify standard and metric designation Examine component, tool, or fastener to see if any marking identifies it. Manufacturer specifications and shop manuals can be referred to. If no markings available, use measuring devices. Inch-to-metric conversion charts

Air Tools (1 of 7) Compressed air equipment Drills, grinders, pumps etc.

Air Tools (2 of 7) Compressed air system made up of: Compressor Pressure regulator Air hose or fixed piping Actual tool or item powered by compressed air A storage tank driven by an electric motor or gasoline engine

Air Tools (3 of 7) Standard compressors are based on piston-type compressors. Operate similar to a piston engine Many new compressors are of scroll compressor type. Pressure regulator controls air pressure supplied to distribution system while air hose or lines transport compressed air from the compressor to the tool.

Air Tools (4 of 7) Compressed air safety Serious and sometimes fatal injuries can be caused by compressed air injected into body. Take care when: Working with air equipment in confined or awkward space Clearing or cleaning the equipment

Air Tools (5 of 7) Air driers and automatic oilers Types of air driers Remove moisture or water from compressed air Water may damage tools Types of air driers Simple water trap A chiller unit

Air Tools (6 of 7) Automatic oilers are designed to regularly oil an air tool or air equipment.

Air Tools (7 of 7) Chassis dynamometers Allows vehicle to run at road speed while safely contained within a shop bay Tuning engines Testing vehicle performance Determining output in torque and horsepower Used with sensors and test instruments Usually bolted to floor or built into floor Has control unit that displays controls for dynamometer and selected engine parameters

Summary (1 of 30) Tools and equipment should only be used for task they were designed to do. Always have a safe attitude when using tools and equipment. Do not use damaged tools; inspect before using, then clean and inspect again before putting them away.

Summary (2 of 30) Lockouts and tagouts are meant to prevent technicians from using tools and equipment that are potentially unsafe. Tools and measuring instruments have USCS or metric system markings to identify size. Compressed air systems are comprised of a compressor, a pressure regulator, an air hose or fixed piping, and tool to be powered.

Summary (3 of 30) Standard compressors use a piston to force air into a storage tank, while scroll compressors use rotating scrolls to compress air. Always use caution because compressed air injuries can be fatal. Many compressed air systems use air driers to remove all traces of moisture from the compressed air.

Summary (4 of 30) Automatic oilers provide regular application of lubricating oil to stream of compressed air, which lubricates air tools and equipment. Chassis dynamometers allow technicians to run vehicles at road speed without leaving the shop. Threaded fasteners include bolts, studs, and nuts and are designed to secure vehicle parts under stress.
