Title: Demonstrate the safe use of standard and metric precision measuring tools
Course: Small Engine Technology I (20110-I) > Section: Applying Safety Practices on the Job

Demonstration should include

- outside and inside micrometers
- depth micrometer
- dial indicators
- torque wrenches
- feeler gauges
- spark-plug-gap gauge
- calipers
- bore gauge
- pressure gauge
- vacuum gauge
- Plastigauge.

Demonstration should emphasize the proper use, maintenance, and calibration requirements per manufacturers' instructions, and government regulations.

Process/Skill Questions:

- How does heat affect the micrometer?
- Why are standard and quality tools necessary when repairing small engines?
- What is torque, and why is proper torque important?
- What is the difference between incremental torque and break-away torque?
- What are the various styles of torque wrenches?
- When are precision measuring tools required?
- What factors can influence precision measurement devices? In what ways?
