The safety-alert symbol (Figure 1) shown in this manual and on the machine identifies important safety messages that you must follow to prevent accidents.

The safety-alert symbol appears above information that alerts you to unsafe actions or situations and is followed by the word DANGER, WARNING, or CAUTION.
DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.
This manual uses two other words to highlight information. Important calls attention to special mechanical information and Note emphasizes general information worthy of special attention.
