Question 1

Technician A says the induction heater is a flameless operation, and can be used to heat moldings and trim as well as steel side rails. Technician B says the cutoff saw blade should be pressed firmly against the surface being cut prior to starting the motor. Who is correct?

Accepted Answer

Technician A is correct because induction heaters do indeed provide a flameless operation and can be used to heat various automotive parts including moldings, trim, and steel side rails without direct contact or flame. Technician B is incorrect because pressing the cutoff saw blade firmly against the surface before starting the motor can be dangerous and is not the recommended procedure. The correct method is to start the saw first and then gently introduce the blade to the material to be cut.

Question 2

A nibbler is used to break spot welds for panel removal.

Accepted Answer

A nibbler is used to make precise cuts in sheet metal, not for breaking spot welds. Spot welds are typically separated using a spot weld cutter, drill, or specialized spot weld chisel.

Accepted Answer

circuit

Question 4

Corrosion ____________________ must be restored after any tools or equipment using heat or welding operations are performed, in order to protect the surface from corroding.

Accepted Answer

The answer of Corrosion ____________________ must be restored after any...

Question 5

Technician A says an air tool should be lubricated with at least 6 drops of oil before before each time it is used. Technician B says the impact gun may be used for installing wheel lugnuts so long as they are used with torque stick sockets. Who is correct?

Accepted Answer

The answer of Technician A says an air tool should...

Question 6

Technician A says the air hammer or chisel is frequently used for removing moldings. Technician B says the tool rest on the bench grinder should be adjusted to within 1/8th inch of the grinding wheel. Who is correct?

Accepted Answer

Technician B is correct because the tool rest on a bench grinder should indeed be adjusted to within 1/8th inch of the grinding wheel for safety and effectiveness. Technician A is incorrect because an air hammer or chisel is not typically used for removing moldings due to the potential for damage.

Question 7

A die grinder is commonly used to dress damaged and corroded bolt threads.

Accepted Answer

The answer of A die grinder is commonly used to...

Question 8

Technician A says that power tools are energized by either electricity, battery , air pressure or by hydraulics. Technician B says that DA is a dual action sander. Who is correct?

Accepted Answer

Technician A is correct in stating that power tools could be energized by electricity, battery, air pressure, or hydraulics. Technician B is also correct in stating that DA is a dual action sander. Therefore, both technicians are correct.

Question 9

Induction ____________________ is an electro-magnetic heating device used for removal of adhesive bonded windows, heating frozen or corroded fasteners, removing moldings, and numerous other operations where heat is necessary.

Accepted Answer

The answer of Induction ____________________ is an electro-magnetic heating device...

Question 10

Technician A says the clamping arm applying pressure to the spot weld drill bit prevents it from wandering during the drilling operation. Technician B says the capacity of a drill is determined by the size rating of the drive motor Who is correct?

Accepted Answer

Technician A is correct that the clamping arm applies pressure to prevent the spot weld drill bit from wandering while drilling. Technician B is incorrect because the capacity of a drill is determined by multiple factors, including the size and power of the drive motor, and the design and quality of the drill bit and chuck. Therefore, Choice A is the best answer.

Question 11

Technician A says using a GFCI prevents the tool from over-heating. Technician B says that personal protective equipment (PPE) must be used any time power tools are used, regardless of their application. Who is correct?

Accepted Answer

GFCI (Ground Fault Circuit Interrupter) helps prevent electric shock by interrupting the flow of current when it senses an imbalance in current flow between the energized and neutral conductor. It does not prevent tools from overheating. Therefore, Technician A is incorrect. However, Technician B is correct in stating that Personal Protective Equipment must be used every time power tools are used to ensure safety.

Question 12

Air driven tools are also called ____________________ tools.

Accepted Answer

The answer of Air driven tools are also called ____________________...

Question 13

Air ratchets and impact wrenches can be used with either standard sockets or heavy duty sockets.

Accepted Answer

Standard sockets are not designed to withstand the high torque of air ratchets and impact wrenches, which require heavy-duty or impact-rated sockets to prevent damage or injury.

Question 14

Air tools run significantly cooler and require little more than a daily lubrication for their maintenance requirements.

Accepted Answer

Air tools run cooler than electric tools because they use compressed air instead of electricity, which means they don't get as hot during use. Additionally, daily lubrication is typically the main maintenance requirement for air tools.

Question 15

The purpose for using a GFCI is to help avoid electric shock.

Accepted Answer

A GFCI (Ground Fault Circuit Interrupter) detects any difference in the electrical current between the hot and neutral wires of a circuit. If there is a leak in the current, it will trip the breaker and shut off power to prevent electric shock. Therefore, the purpose of using a GFCI is to help avoid electric shock.

Question 16

Technician A says the pistol grip grinder is the best choice for removing excess weld material that may occur during a repair process. Technician B says an air ratchet turns the bolt or nut with a continuous driving motion until it stalls out and then it continues to hammer the fastener to finish tightenting it. Who is correct?

Accepted Answer

Technician A is incorrect because a pistol grip grinder is not typically used for removing weld material; an angle grinder is more suitable. Technician B is incorrect because an air ratchet does not hammer the fastener; it simply stalls when it reaches its torque limit.

Question 17

Technician A says whenever using an air ratchet, the trigger should be depressed until the tool stalls out; the fastener is then sufficiently tightened. Technician B says the nibbler can be used to dress plug welds. Who is correct?

Accepted Answer

Technician A is incorrect because using an air ratchet until it stalls out can lead to over-tightening and potentially damaging the fastener or the material it's securing. Technician B is incorrect because a nibbler is used for cutting sheet metal and not suitable for dressing (finishing or smoothing) plug welds.

Question 18

To avoid personal injury, ____________________ should always be worn when one uses the air chisel.

Accepted Answer

The answer of To avoid personal injury, ____________________ should always...

Question 19

Technician A says most pistol grip grinders rotate at a rate of approximately 20,000 RPM. Technician B says an impact wrench stops turning once it stall out. Who is correct?

Accepted Answer

Most pistol grip grinders do rotate at approximately 20,000 RPM, which is a common industry standard. Technician B is incorrect because an impact wrench can continue to turn even after it has stalled out, which can be dangerous if not handled properly.

Question 20

Technician A says that air tools are the technicians' tool of choice because they are lighter weight than cordless tools. Technician B says that most electric variable speed buffer/polisher is designed to operate at speeds ranging from 1000 to 2500 RPM's, which is the optimum speed for buffing and polishing operations. Who is correct?

Accepted Answer

Technician A is correct because air tools are often preferred for their lighter weight compared to cordless tools, which can reduce fatigue during prolonged use. Technician B is also correct as most electric variable speed buffer/polishers are designed to operate within a range of 1000 to 2500 RPMs, which is indeed the optimum speed range for most buffing and polishing tasks, allowing for effective and controlled surface treatment.
