Warning Boxes
Warning Box Words & Icons
Warning Boxes are provided throughout this Technical Manual and are used to call attention to various details about either
the equipment that are important enough to separate from the normal operating descriptions and/or procedures or a safety-
related situation that the operator must be aware of. The appearance of the basic Warning Box is shown in Figure a. There
are generally four information points provided by each Warning Box that follow a defined pattern. Figure a defines the
positions of the information points.
Figure a - Warning Box Definition
Icon 1:
Icon 1 is the primary indication of the contents of the Warning Box. The Icon is meant to visually alert the reader to the
level of importance of the Warning.
Icons 2, 3, 4:
The icons that appear to the right of the Warning Box Classification provide a secondary indication of the contents of the
Information Box. The position is labeled Icon 2, 3, 4 in Figure a (above) because there may be multiple types of alerts
associated with the warning. The types of Icons found in Icon Box 2 are as follows:
When Icon 2 is the same as Icon 1, it means that there is no further specific information about the type of Alert.
If Icon 2 is different than the icon shown in Icon Box 1, it means that there is more specific information available about the
type of Alert. An example of an Warning Box where there would be two different Icons shown in Icon Box 1 and Icon Box
2 would be that of a burn hazard. In this case, Icon Box 1 will show an Icon representing a burn hazard. If the burn hazard
was created by a particular substance such as gasoline, Icon Box 2 would be an Icon indicating a Flammable Fluid.
In certain instances, additional icons will appear after Icon #2. These icons will either enhance the definition of the warning
or they will indicate the presence of additional hazards that may exist either because of the original condition or in addition
to the original condition.
Warning Box Alert Classifications
The Warning Box Alert Classification is an indication of the level of importance of the Warning Box. The various levels of
Alert Types are defined below, from the most important (Danger) to items of lesser importance.
Danger:
Danger refers to immediate hazards that will result in severe personal injury or death.
Warning:
Warning refers to a hazard or unsafe method or practice that may result in severe personal injury or death.
Caution:
Caution refers to a hazard or unsafe method or practice that may result in personal injury or equipment damage.
Note:
Note refers to an important feature that the operator should be aware of for maximum operating efficiency of the
equipment.

Plugged in or Warm
