Question

technician a says you should place the air ratchet setting to clockwise to loosen a fastener. technician b says a fastener must be set to the proper torque after using an air ratchet. who is correct?
a) technician a
b) technician b
c) both a and b
d) neither a nor b

Explanation:

• Air ratchet settings: To loosen a fastener, the air ratchet should be set to counter - clockwise (not clockwise as Technician A says). So Technician A is incorrect.
• Torque setting: After using an air ratchet (which is mainly for loosening or initial tightening), the fastener must be set to the proper torque. So Technician B is correct.

Answer:

B. Technician B
