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 a dust mask, 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 when making blind and/or plunge cuts. Before each use, check that the drill bit is free from damage and excessive wear. Discard drill 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. Only drill materials that are listed on the package. Use a drill motor that is equipped with a support handle. Start cutting with a light forward pressure.
