Quick-Release Chuck (DCF815)
(Fig. 2, 4, 5)
NOTE: The chuck accepts 1/4" (6.35 mm) hex accessories and 1"
(25.4 mm) bit tips only.
Place the forward/reverse button (B) in the locked off (center) position
or remove battery pack before changing accessories.
To install an accessory, fully insert the accessory. The accessory is
locked into place (Fig. 4).
To remove an accessory, pull the chuck collar (C) away from the front
of the tool. Remove the accessory and release the collar (Fig. 5).

To install a socket on the hog ring anvil, firmly push socket onto
the anvil (J). The hog ring (K) compresses to allow the socket to slide
on. After the socket is installed, the hog ring applies pressure to help
provide socket retention.
To remove a socket, grasp the socket and firmly pull it off.
Usage
Your impact tool generates the following output torque:
Cat # Ft.-Lbs.
DCF813 96
DCF815 79
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 socket on the fastener head. Keep the tool pointed
straight at the fastener.
2. Press switch to start 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.
• Socket size: Failure to use the correct socket 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.
