Excessive torque may cause breakage and possible personal injury. 1. Place the accessory on the fastener head. Keep the tool pointed straight at the fastener. 2. Press switch to start operation. Release switch to stop operation. Always check torque with a torque wrench, as the fastening torque is affected by many factors including the following: • Voltage: Low voltage, due to a nearly discharged battery, will reduce fastening torque. • Accessory size: Failure to use the correct accessory size will cause a reduction in fastening torque. • Bolt size: Larger bolt diameters generally require higher fastening torque. Fastening torque will also vary according to length, grade, and torque coefficient. DCF898 J 13
