Study Notes

Air Compressor and Tools

An air compressor provides compressed air for automotive service facilities.
Typical air pressure in shop compressed air systems ranges from 100-150 PSI.
Quick disconnect couplings allow air hoses and tools to connect without a wrench.
An electric motor is used to set a specific pressure in the compressed air system.
Air tools are often referred to as pneumatic tools.
Lubricating air tools before use helps remove water and prevent damage.

Air Wrenches

Air wrenches efficiently install or remove nuts and bolts.
Direction of rotation on an impact wrench is controlled by a button or switch.
Care is essential when loosening or tightening fasteners with an air wrench to avoid stripping or breaking them.
An air ratchet is a specialized air wrench for quick fastener removal, typically equipped with a 3/8 inch drive.

Sockets and Torque

Impact sockets are made from case-hardened steel, thicker and stronger than conventional sockets, which can break easily from impact.
Impact wrenches should not replace torque wrenches as they may not apply the correct torque specifications.

Air Hammer and Blowgun

Air hammers are used for driving and cutting operations.
Always press an air hammer tightly against the workpiece before turning it on.
Air-powered blowguns are utilized for drying and cleaning parts washed in solvents.

Drilling and Grinding Tools

Air drills are highly advantageous for repair tasks due to their power output adjustment options.
Rotary brushes help remove gasket material, carbon deposits, and rust easily.
Abrasive pads can also be used with air drills.
Bench grinders are used for grinding, polishing, and cleaning operations and typically have two wheels.
Key safety rules for bench grinders include wearing eye protection and using shields.

Drill Press and Bits

Drill bits, often called twist drills, are used for creating holes in metal and plastic.
Bits are tightened in the drill's chuck, using a special key.
Drill bits are usually made of carbon steel or high-speed steel.
A drill press is a large, bench-mounted or floor-mounted drill requiring specific safety protocols.

Hydraulic Tools

Hydraulic tools operate with pressurized liquid.
A floor jack should be placed under a solid part of the car to avoid damage.
A transmission jack is specifically designed to hold transmissions during installation or removal.
Portable engine cranes raise and assist with engine removal and installation.

Presses and Stands

Pullers install or remove high-force parts like gears and bearings.
A hydraulic press operates similarly to a mechanical press but uses hydraulic power.
