COMPLETE QUESTIONS AND DETAILED SOLUTIONS
LATEST UPDATE THIS YEAR JUST RELEASED
1.
Which maintenance strategy is generally most effective for reducing
unexpected equipment failures while controlling long-term repair
costs?
A. Corrective maintenance after every failure
B. Preventive maintenance performed according to established
schedules
C. Replacing every component annually
D. Waiting until equipment becomes noisy
Answer: B
Rationale: Preventive maintenance uses scheduled inspections,
servicing, lubrication, adjustment, and replacement to identify
problems before they become major failures.
2.
Before beginning maintenance on powered equipment, what should a
technician do first when unexpected energization could create a
hazard?
,A. Remove the equipment cover
B. Increase the equipment speed
C. Isolate and control hazardous energy
D. Ask another employee to watch the switch
Answer: C
Rationale: Hazardous energy must be isolated and controlled before
servicing when unexpected startup or release of stored energy could
cause injury.
3.
Why should maintenance technicians document completed preventive-
maintenance activities?
A. Documentation eliminates the need for inspections
B. Records help establish equipment history and future maintenance
needs
C. Documentation increases equipment operating temperature
D. Records replace manufacturer instructions
Answer: B
Rationale: Maintenance records provide valuable information about
repairs, recurring failures, service intervals, and component condition.
4.
A technician notices that a motor is vibrating significantly more than
during previous inspections. What is the best initial response?
,A. Ignore the vibration unless the motor stops
B. Increase the motor's operating speed
C. Investigate possible mechanical or alignment problems
D. Paint the motor housing
Answer: C
Rationale: Increased vibration can indicate imbalance, misalignment,
worn bearings, loose components, or other developing mechanical
problems.
5.
Why is manufacturer documentation important when maintaining
building equipment?
A. It provides equipment-specific procedures and specifications
B. It eliminates all safety requirements
C. It guarantees every repair will be inexpensive
D. It allows technicians to bypass protective devices
Answer: A
Rationale: Manufacturer manuals provide recommended service
procedures, specifications, replacement parts, lubrication
requirements, and safety information.
6.
What is the primary purpose of a maintenance inspection checklist?
, A. To eliminate technician judgment completely
B. To provide a consistent method for checking important components
C. To increase equipment electrical consumption
D. To replace all manufacturer instructions
Answer: B
Rationale: Checklists improve consistency and reduce the likelihood
that important inspection or maintenance tasks will be overlooked.
7.
A technician discovers a cracked belt during a routine equipment
inspection. What is generally the best action?
A. Continue operating indefinitely
B. Replace the belt according to applicable procedures
C. Remove the belt guard permanently
D. Lubricate the cracked belt
Answer: B
Rationale: A cracked belt may fail unexpectedly and should normally be
replaced with the correct type and properly tensioned.
8.
Why should maintenance technicians avoid using replacement
components that do not meet equipment specifications?
