To reduce the risk of injury, read the instruction manual and follow the safety regulations of the power tool you will be using with your Spyder accessory. Use personal protective equipment. Always wear eye protection. Protective equipment such as non-skid safety shoes, protective apparel and hearing protection should be used in appropriate conditions to reduce the risk of personal injury. WARNING: Operating the tool without wearing proper protection may result in serious injury. To reduce the risk of explosion, electric shock, and property damage, always check the work area for hidden gas pipes, electrical wires, and water pipes before driving fasteners. Before each use, check that the bit is free from damage and excessive wear. Discard bit if damage is noticed or suspected as this can cause the bit to shatter or break and can create dangerous flying debris and/or create other unsafe situations that may cause injury. Use a driver bit of the correct shape and size for your fastener. To prevent slipping and/or stripping of the fastener head, apply ample pressure to the bit and keep it perfectly in-line with the fastener. Do not use to pry or chisel.
