This subset of tools includes the most widely used power tool in the world — drills — along with powered wrenches, hammers, rotary hammers, and hammer drills. Bracing and maintaining a firm grip on these powerful hand-held tools is critical, so is protective eyewear and earwear in the case of extended use. |

Lesson Suggestion... Create an Expert
Objective:
To have students become thoroughly
acquainted with at least one hand-held power tool owner's
manual, to note the issues that are typically covered and
the information that is provided, to recognize the manual's
value as a reference tool and resource, to recognize when
to refer back to it.
Materials/Requirements:
Several hand-held power
tools and their owner's manuals.
What To Do:
Discuss the importance of owner's manuals
as a starting point for becoming acquainted with any power
tool. Point out the kind of information that is typically
provided in an owner's manual and how that information
might be useful.
Assign
each student or team of students to read and
digest one instruction manual that accompanies one of the
hand-held power tools in your shop. Ask each student to
create a written outline on the manual's highlights and
prepare a presentation for his classmates.
Distribute copies of the outline to the other students
and ask the student who created it to instruct his peers
on the proper use of the tool based on what he has read
and learned. Have him or her also relate dangerous
situations that could develop if the proper procedures are
not followed.
Encourage the other students to question their
"instructor," and to evaluate how thorough the instruction
session was. Ask them to suggest instances when it would
be appropriate to re-read certain sections of the manual.
Finally, photocopy the guidelines for each tool as presented
in Safety Is Specific and provide each student with a copy.
Have your students compare each presentation to the rules
outlined in Safety Is Specific. Have all the vital points been
covered? Has any important information been overlooked? If
so, what might the consequences be of overlooking that
information? Discuss.
