Question 1

A set of safety practices and procedures that are intended to reduce the risk of technicians inadvertently using tools that have been determined to be unsafe is known as:

Accepted Answer

Lockout is a set of safety practices and procedures that are intended to reduce the risk of technicians inadvertently using tools that have been determined to be unsafe.

Question 2

Tech A says that knowing how to use tools correctly creates a safe working environment. Tech B says that a flare nut wrench is used to loosen very tight bolts and nuts. Who is correct?

Accepted Answer

Knowing how to use tools correctly is essential for creating a safe working environment. A flare nut wrench is specifically designed for use on soft metal nuts, such as those found on brake lines, and is not typically used for loosening very tight bolts and nuts.

Question 3

Tech A says that lockout is designed to secure a vehicle after all work on it has been completed. Tech B says that tag-out is used when a tool is no longer fit for use and identifies what is wrong with it. Who is correct?

Accepted Answer

Lockout is a safety procedure used to ensure that machines are properly shut off and not started up again before the completion of maintenance or repair work. Tag-out is used to indicate that a tool or equipment is not safe to use and provides information about the issue.

Question 4

Which of these wrenches can be awkward to use once the nut or bolt has been loosened a bit?

Accepted Answer

The answer of Which of these wrenches can be awkward...

Question 5

Oil filters should be installed using:

Accepted Answer

Oil filters should be installed by hand to ensure they are not overtightened, which can cause damage or make them difficult to remove later.

Question 6

When tightening lug fasteners, an impact wrench should:

Accepted Answer

The answer of When tightening lug fasteners, an impact wrench...

Question 7

Which of these would you use for a wider grip and a tighter squeeze on parts too big for conventional pliers?

Accepted Answer

Arc joint pliers, also known as channel locks, have adjustable jaws that allow for a wider grip and a tighter squeeze on larger parts.

Question 8

When a large chisel needs a really strong blow, use a:

Accepted Answer

A sledgehammer is designed to deliver powerful blows, making it suitable for tasks requiring significant force, such as striking a large chisel.

Question 9

Which style of torque wrench is the simplest and least expensive?

Accepted Answer

The beam torque wrench is the simplest and least expensive type, as it uses a simple mechanical design without any complex mechanisms or electronics.

Question 10

Tech A says that it is usually better to pull a wrench to tighten or loosen a bolt. Tech B says that pushing a wrench will protect your knuckles if the wrench slips. Who is correct?

Accepted Answer

Pulling a wrench is generally safer and more effective because it allows for better control and reduces the risk of injury if the wrench slips.

Question 11

Tech A says that torque wrenches need to be calibrated periodically to ensure proper torque values. Tech B says that when using a clicker-style torque wrench, keep turning the torque wrench ⅛-¼ turn to make sure the bolt is properly tightened. Who is correct?

Accepted Answer

Torque wrenches need to be calibrated periodically to ensure they provide accurate torque values. Tech B's advice is incorrect; once a clicker-style torque wrench clicks, the desired torque is reached, and further turning can lead to over-tightening.

Question 12

Tech A says that a dead blow hammer reduces rebound of the hammer. Tech B says that a dead blow hammer should be used with a chisel to cut the head of a bolt off. Who is correct?
​

Accepted Answer

A dead blow hammer is designed to minimize rebound and absorb shock, making it effective for tasks requiring controlled force. However, it is not typically used with a chisel for cutting bolts, as this requires a more precise tool like a regular hammer or a cutting tool.

Question 13

Tech A says that gaskets can be removed quickly and safely with a hammer and sharp chisel. Tech B says that extreme care must be used when removing a gasket on an aluminum surface. Who is correct?

Accepted Answer

Tech B is correct because using a hammer and sharp chisel can damage the aluminum surface. Extreme care is needed to avoid gouging or scratching the aluminum when removing a gasket.

Question 14

Tech A says that when using a file, apply pressure to file in the direction of the cut and no pressure when pulling the file back. Tech B says that file cards are used to file uneven surfaces. Who is correct?

Accepted Answer

The answer of Tech A says that when using a...

Question 15

The depth of blind holes in housings can best be measured using a:

Accepted Answer

A vernier caliper is suitable for measuring the depth of blind holes due to its depth rod, which allows for precise measurement of depths.

Question 16

Tech A says that when using a micrometer, a "standard" is used to hold the part you are measuring. Tech B says that the micrometer spindle should be firmly closed against the anvil prior to storage. Who is correct?

Accepted Answer

A "standard" is not used to hold the part being measured; it is used to calibrate the micrometer. The micrometer spindle should not be firmly closed against the anvil during storage to avoid damaging the instrument.

Question 17

Tech A says that a feeler gauge is used to measure the diameter of small holes. Tech B says that a feeler gauge and straight edge are used to check surfaces for warpage. Who is correct?

Accepted Answer

A feeler gauge is used to measure gap widths, and when used with a straight edge, it can check surfaces for warpage. It is not used to measure the diameter of small holes.

Question 18

Absorbing some chemicals through the skin over time can cause permanent harm to your body.

Accepted Answer

Certain chemicals can penetrate the skin and accumulate in the body, potentially causing long-term health effects such as organ damage or cancer.

Question 19

Always use chemical gloves when using any cleaning material, because excessive exposure to cleaning materials can damage skin.

Accepted Answer

Cleaning materials often contain chemicals that can be harmful to the skin, so wearing chemical gloves provides protection against potential irritation or damage.

Question 20

At the end of each working week, clean the tools and equipment you used and check them for any damage.

Accepted Answer

The answer of At the end of each working week,...
