the left side of the tool. The centre position of the control button
locks the tool in the off position. When changing the position of
the control button, be sure the trigger isreleased.
NOTE: The first time the tool is run after changing the direction
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.
