a. are both stronger
b. require more training
c. do not require certification
d. are much slower

1. before using a pneumatically powered nailer for the first time, it is important to ______.

c. ensure it is plugged into a gfci receptacle
d. read the manufacturers manual

1. most craftworkers who use pneumatic nailers operate their compressors at ______.

a. 30 to 80 psi
b. 60 to 110 psi
c. 70 to 120 psi
d. 90 to 140 psi

1. a porta-power® is an example of a(n) ______.

b. pneumatic tool
c. hydraulic tool
d. battery-powered tool

Explanation:

Question 22

To solve this, we analyze each option:

• Option a: Powder - actuated nailers are generally stronger for heavy - duty tasks, so electric and pneumatic are not both stronger. Eliminate a.
• Option b: Powder - actuated nailers require more training and certification due to their explosive nature. Electric and pneumatic do not require as much training. Eliminate b.
• Option c: Powder - actuated nailers need certification, while electric and pneumatic nailers typically do not require certification. This is correct.
• Option d: Electric and pneumatic nailers are not much slower; in fact, they can be efficient for many tasks. Eliminate d.

When using a tool for the first time, the most important step is to read the manufacturer's manual to understand its operation, safety procedures, etc.

• Option a: Disassembling the nailer for inspection is not the first step; it may even damage the tool if done incorrectly without proper knowledge. Eliminate a.
• Option b: Loading nails is done after understanding the tool, not as the first step. Eliminate b.
• Option c: Pneumatic nailers are powered by air compressors, not plugged into an outlet (that's for electric tools). Eliminate c.
• Option d: Reading the manufacturer's manual is essential for first - time use. This is correct.

In the context of pneumatic nailers, most craftworkers operate their compressors at 60 to 110 psi. This is a standard range for operating pneumatic nailers efficiently.

• Option a: 30 to 80 psi is too low for most pneumatic nailer applications. Eliminate a.
• Option b: 60 to 110 psi is the typical range. This is correct.
• Option c: 70 to 120 psi is a bit higher than the standard range for most craftworkers. Eliminate c.
• Option d: 90 to 140 psi is too high and may cause issues with the nailer. Eliminate d.

Answer:

c. do not require certification
