TOOL SETS AND

ACCESSORIES

A beginning service technician may wish to start

with a small set of tools before spending a lot of

money on an expensive, extensive tool box. See

Figures 1-27 through 1-29.

BRAND NAME VERSUS

PROPER TERM

Technicians often use slang or brand names of

tools rather than the proper term. This results in

some confusion for new technicians. Some examples

are given in the following table.

(a)

Figure 1-28. An inexpensive muffin tin can be used

to keep small parts separated.

(b)

Figure 1-27. (a) A beginning technician can start

with some simple basic hand tools. (b) An experienced,

serious technician often spends several thousand

dollars a year for tools such as those found in this

large (and expensive) tool box.

Figure 1-29. A good fluorescent trouble light is essential.

A fluorescent light operates cooler than an incandescent

light and does not pose a fire hazard as

when gasoline is accidentally dropped on an unprotected

incandescent bulb used in some trouble lights.
