THE NATURE OF HAZARDOUS SITUATIONS
The use of portable automotive lifting and support devices is subject to certain hazards that cannot be prevented by mechanical means,
but only by the exercise of intelligence, care, and common sense. It is therefore essential to have owners and personnel involved in the use
and operation of the equipment who are careful, competent, trained, and qualified in the safe operation of the equipment and its proper use.
Examples of hazards are dropping, tipping or slipping of loads caused primarily by improperly secured loads, overloading, off-centered loads,
use on other than hard level surfaces, and using equipment for a purpose for which it was not designed.
METHODS TO AVOID HAZARDOUS SITUATIONS

missing components. Make corrections before using.
• User and bystanders must wear eye protection that meets ANSI Z87.1 and OSHA standards.
• Use as a matched pair only.
• Use only on a hard level surface capable of supporting the load.
