Demonstrate the use of standard and metric hand tools.

Demonstration should include the various types of hand tools (including specialty tools, fasteners, and measuring tools) used in agricultural mechanics. Demonstration should emphasize the use, the hazards, the precautions, and the maintenance procedures associated with each, in accordance with manufacturers' instructions and government regulations. Hand tools could include

• socket set components
• wrenches (including common end wrenches)
• screwdrivers
• pliers
• hammers
• punches and chisels
• specialty cutting tools (e.g., hack saw, tubing cutter, hand reamer, file)
• specialty electrical system tools (e.g., volt/ohmmeter, dwell/tachometer, timing light, remote starter switch)
• battery specialty tools (e.g., cable puller, terminal and post cleaner, lifting or carrying strap)
• lubrication specialty tools (e.g., transmission funnel, oil filter-removal tool, grease gun)
• other miscellaneous specialty tools (e.g., air nozzles, C-clamp, puller set, pressure gauge, screw extractor).

Process/Skill Questions:

• Why is it important to use the proper hand tool for each job?
• When a wrench is used, why should it always be pulled toward the body?
• Why is it necessary to keep hand tools clean and free of grease?
