C. Focus on components, symbols and schematics for the named mechanical system integrated across the tasks expected in mec and treat preventive
maintenance, records and return-to-service checks to support reliable, ethical mechanical, fluid-po as outside the immediate decision.
D. Complete the task first and reconstruct evidence for preventive maintenance, records and return-to-service checks to support reliable, ethical
mechanical, fluid-po later from memory.
Correct Answer: A
Explanation: Verification is required before acceptance. Because the record shows 2 unresolved item(s), preventive maintenance, records and
return-to-service checks to support reliable, ethical mechanical, fluid-po should be checked against applicable criteria and current evidence
before work continues; this supports safety, quality, traceability, and defensible professional judgment.

12. A qualified worker is applying materials, tubing, hose, fittings, seals and compatibility within the mechanical, fluid-power and motion syste
while reviewing field documentation. What should be checked before accepting the work as satisfactory? The current record shows 6 completed
checks, 2 unresolved item(s), and 1 hour(s) since the last documented review.
A. Proceed mainly from prior experience and address materials, tubing, hose, fittings, seals and compatibility within the mechanical, fluid-power and
motion syste only if a problem appears.
B. Focus on measurement, alignment, adjustment and tolerance verification with decisions and evidence relevant to mechanic and treat materials,
tubing, hose, fittings, seals and compatibility within the mechanical, fluid-power and motion syste as outside the immediate decision.
C. Complete the task first and reconstruct evidence for materials, tubing, hose, fittings, seals and compatibility within the mechanical, fluid-power
and motion syste later from memory.
D. Verify applicable requirements, current conditions, and objective evidence for materials, tubing, hose, fittings, seals and compatibility within
the mechanical, fluid-power and motion syste before proceeding, and resolve the 2 outstanding item(s).
Correct Answer: D
Explanation: Verification is required before acceptance. Because the record shows 2 unresolved item(s), materials, tubing, hose, fittings, seals
and compatibility within the mechanical, fluid-power and motion syste should be checked against applicable criteria and current evidence before
work continues; this supports safety, quality, traceability, and defensible professional judgment.
13. Which observation most clearly indicates that pumps, actuators, valves, drives and control-device behavior as applied to mechanical,
fluid-power and motion has been addressed correctly while reviewing field documentation? The current record shows 7 completed checks, 2
unresolved item(s), and 1 hour(s) since the last documented review.
A. Proceed mainly from prior experience and address pumps, actuators, valves, drives and control-device behavior as applied to mechanical, fluid-power
and motion only if a problem appears.
B. Focus on assembly sequence, tool selection and prevention of workmanship damage for safe, accurate work in mechanical, and treat pumps, actuators,
valves, drives and control-device behavior as applied to mechanical, fluid-power and motion as outside the immediate decision.
C. Complete the task first and reconstruct evidence for pumps, actuators, valves, drives and control-device behavior as applied to mechanical,
fluid-power and motion later from memory.
D. Verify applicable requirements, current conditions, and objective evidence for pumps, actuators, valves, drives and control-device behavior as
applied to mechanical, fluid-power and motion before proceeding, and resolve the 2 outstanding item(s).
Correct Answer: D
Explanation: Verification is required before acceptance. Because the record shows 2 unresolved item(s), pumps, actuators, valves, drives and
control-device behavior as applied to mechanical, fluid-power and motion should be checked against applicable criteria and current evidence
before work continues; this supports safety, quality, traceability, and defensible professional judgment.
14. While reviewing field documentation, a discrepancy is found involving measurement, alignment, adjustment and tolerance verification with
decisions and evidence relevant to mechanic. Which response is most appropriate? The current record shows 8 completed checks, 2 unresolved
item(s), and 1 hour(s) since the last documented review.
A. Proceed mainly from prior experience and address measurement, alignment, adjustment and tolerance verification with decisions and evidence relevant
to mechanic only if a problem appears.
B. Focus on leak, friction, heat, vibration and contamination diagnosis through realistic mechanical, fluid-power and moti and treat measurement,
alignment, adjustment and tolerance verification with decisions and evidence relevant to mechanic as outside the immediate decision.
C. Complete the task first and reconstruct evidence for measurement, alignment, adjustment and tolerance verification with decisions and evidence
relevant to mechanic later from memory.
D. Verify applicable requirements, current conditions, and objective evidence for measurement, alignment, adjustment and tolerance verification with
decisions and evidence relevant to mechanic before proceeding, and resolve the 2 outstanding item(s).
Correct Answer: D
Explanation: Verification is required before acceptance. Because the record shows 2 unresolved item(s), measurement, alignment, adjustment and
