Reciprocating jig saw blades can cause lacerations or puncture wounds. Kick back may occur if power tool instructions are not followed. Always wear a mask to prevent inhalation of dust and debris. Wear safety glasses and protective apparel to prevent injury from flying debris. Check the blade before use in the power tool – if excessive wear is present, the blade is bent, cracked or damaged, replace blade before use. Important instructions and warnings are contained in the tool owner’s manual – please refer to the power tool owner’s manual before using the tool with this tool. Failure to heed all safety instructions, warnings, and in-use recommendations by the power tool manufacturer regarding the use of the jig saw and blade could result in serious bodily injury.
