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.
Worklights (Fig. A)
There is a worklight

located above the trigger switch
worklight will be activated when the trigger switch is depressed.
When the trigger is released, the worklight will stay illuminated
for up to 20 seconds. If the trigger switch remains depressed,
the worklights will remain on.
nOTE: The worklight is for lighting the immediate work surface
and are not intended to be used as a flashlight.
Quick-Release Chuck (Fig. A, C)
WARNING: Use only impact accessories. Non-impact
accessories may break and cause a hazardous condition. Inspect
accessory prior to use to ensure that it con tains no cracks.
nOTE: The chuck accepts 6.35 mm hex accessories and
25.4 mm bit tips only. Using 25.4 mm bits allows better access
in tight spaces.
Place the forward/reverse button
position or remove battery pack before changing accessories.

Usage
Your impact tool generates the following maximum torque:
Cat #
Nm
DCF787
170
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.
• Bolt Size: Larger bolt diameters generally require higher
fastening torque. Fastening torque will also vary according to
length, grade, and torque coefficient.
• Bolt: Ensure that all threads are free of rust and other debris to
allow proper fastening torque.
• Material: The type of material and surface finish of the material
will affect fastening torque.
• 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
or damaged.
