The employee was using a Makita Magnesium Model 5007MG Makita Magnesium 7-1/4- inch portable circular saw (serial number: 00051436 K) equipped with a guard to cut the lumber. The employee was wearing PPE including safety glasses, gloves and steel toe boots. The employee was holding the saw with his right-hand during operation while preparing to cut an angle. He was using his left hand to hold the wood on the table with a portion of the wood to be cut extending off of the table. The saw hit a knot and became stuck in the wood. The saw continued to move forward pulling the wood along with is left hand towards the rotating saw blade. The employee's left index finger was struck by the saw blade. The employee received medical treatment without hospitalization for an amputation to his index finger to the second knuckle.
