Watch it work


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, hard hat and hearing protection should be used in appropriate conditions to reduce the risk of personal injury. WARNING: Operating the tool without wearing proper eye 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 cuts. Before each use, check that the blade is clean, sharp and free from cracks, loose teeth, missing teeth, broken teeth, and any other damage. Do not use a dirty, dull, or damaged blade as this may result in blade pinching, binding or stalling, kickback and loss of control. These situations can cause the saw to jump back at the operator and result in a serious injury. Carbide is a hard, but brittle material. Foreign objects in the workpiece such as wire or nails can cause the carbide tips to crack or break. Overheating a saw blade can cause it to warp and result in kickback. Buildup of sap on the blades, insufficient blade set, dullness, and unguided cuts, can all cause an overheated blade and kickback. Always use blades of the correct size with the correct arbor hole shape and size for your power tool. Blades that do not match the mounting hardware of the power tool will run eccentrically, causing loss of control, increasing the risk of personal injury. Make sure the speed marked on the blade is at least as high as the no-load RPM marked on the power tool. To assure proper rotation direction of the saw blade, the arrow direction on the blade must correspond with the arrow direction on the saw. Mount blade properly with the correct blade washers and bolt for the power tool. To reduce the risk of injury, never operate the power tool without proper safety guards in place.
