1. Avoid situations that place you the operator in between the tool and the vehicle If you end up in this position stop the tool and place yourself on the opposite or open side of the tool Be aware of a rotating tool to avoid the possibility of pinching your trigger hand between the tool and the object you are working on Avoid cutting objects that are not intended for the tool When cutting an object blindly such as a door hinge pay close attention to the movement of the cutter If the cutter twists or rotates excessively stop and reposition cutter blades Continuing to operate the tool when this condition exists could lead to blade damage or breakage which could injure personnel 16 Page When lifting vertically with a spreader or ram be sure to use cribbing as you are lifting to avoid the possibility of an object falling and injuring personnel or patients 17 Page2.
