Requires no maintenance
Greater mobility without cords
Cheaper than air tools
Which electric tool is commonly used to remove rust or paint from metal surfaces?
Jigsaw
Angle grinder
Impact wrench
Pneumatic sander
Pneumatic tools are powered by:
Batteries
Compressed air
Hydraulic fluid
Gasoline
The device that stores and supplies compressed air to pneumatic tools is the:
Regulator
Compressor
Gauge
Ventilator
Before disconnecting a pneumatic tool, you should always:
Increase the pressure
Lubricate the air line
Shut off and bleed the air pressure
Replace the air hose
Which tool is most commonly used to quickly remove lug nuts from wheels?
Pneumatic impact wrench
Cordless drill
Air ratchet
Bench grinder
What does CFM stand for when rating an air compressor?
Cubic Foot Maintenance
Cubic Feet per Minute
Compressed Force Meter
Compressor Flow Module
Which of the following is a safety feature on most electric grinders?
Quick-release chuck
Side handle
Guard over the wheel
Battery indicator
Why is it important to lubricate pneumatic tools regularly?
To increase air pressure
To prevent rust and internal wear
To cool the compressor
To reduce hose tangling
Which of these is NOT a typical pneumatic tool?
Air ratchet
Air hammer
Cordless drill
Impact wrench
What is the typical air pressure (PSI) required for most automotive pneumatic tools?
10–20 PSI
30–40 PSI
90 PSI
200 PSI
A die grinder is primarily used for:
Cutting wood
Grinding, polishing, and porting metal
Drilling holes in concrete
Inflating tires
Which part of a pneumatic system reduces pressure to a safe operating level for tools?
Compressor
Air dryer
Regulator
Filter
Which electric tool converts electrical energy into reciprocating motion for cutting metal or plastic?
Impact driver
Circular saw
Reciprocating saw
Angle grinder
Air hoses should be inspected for:
Color fading
Cracks, leaks, and wear
Proper battery charge
Oil viscosity
A key difference between an air ratchet and an impact wrench is:
Air ratchet produces high torque impacts
Air ratchet is designed for lighter fasteners and tighter spaces
Impact wrench spins only slowly
Air ratchet uses electricity
What should you always wear when using grinders or sanders?
Rubber gloves
Safety glasses or face shield
Steel-toe boots only
None of the above
Electric drills used in auto shops often feature:
Reversible direction and variable speed
Only one speed
Air-powered motors
Built-in torque wrenches
Why is it dangerous to use damaged power cords or air hoses?
It reduces tool speed
It could cause injury or electric shock
It increases CFM
It lowers PSI
Pneumatic tools can run without a compressor if connected directly to shop air lines.
