Usage
Your impact tool generates the following maximum torque:
Cat # Nm Ft.-Lbs. In.-Lbs
DCF809 190 142 1700
CAUTION: Ensure fastener and/or system will withstand
the level of torque generated by the tool. Excessive torque
may cause breakage and possible personalinjury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at thefastener.
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 fasteningtorque.
• Accessory size: Failure to use the correct accessory
size will cause a reduction in fasteningtorque.
• Bolt Size: Larger bolt diameters generally
require higher fastening torque. Fastening torque
will also vary according to length, grade, and
torquecoefficient.
• Bolt: Ensure that all threads are free of rust and other
debris to allow proper fasteningtorque.
• Material: The type of material and surface finish of
the material will affect fasteningtorque.
• Fastening Time: Longer fasten ing time results in
increased fastening torque. Using a longer fastening
time than recom mended could cause the fasteners to
be overstressed, stripped ordamaged.
MAINTENANCE
Your power tool has been designed to operate over a long
period of time with a minimum of maintenance. Continuous
satisfactory operation depends upon proper tool care and
