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).
Anvil with Hog Ring (Fig. 2, 6)
DCF813
CAUTION: Use only impact sockets. Non-impact
sockets may break and cause a hazardous condition. Inspect
sock et prior to use to ensure that it con tains no cracks.
Place the forward/reverse button (B) in the locked off (center)
position or remove battery pack before changing accessories.

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. In.-Lbs.
DCF813-XE 96
DCF815-XE 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.
• 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.
