CAUTION

The purpose of safety symbols is to attract your attention to possible dangers. The safety or attention symbols 
and their explanations deserve your careful attention and understanding. The warnings do not, by themselves, 
eliminate any danger. The instructions or warnings they give are not substitutes for proper accident prevention 
measures.

Look for these symbols to point out safety precautions or important information.
