of rotation, you may hear a click on start up. This is normal and
does not indicate a problem.

Usage
Your impact tool generates the following maximum torque:
Cat # Nm Ft.-Lbs. In.-Lbs
DCF787 170 125 1500
CAUTION: Ensure fastener and/or system will withstand
the level of torque generated by the tool. 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 the 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.
