Worklight (fig. 1)
Cat # | Nm |
There is a worklight (g) located just above the trigger switch (a). The worklight will be activated when the trigger switch is squeezed.
NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a flashlight.
Quick-Release Chuck (fig. 4)
DC825, DC827, DC835, DC837, DC845
NOTE: The chuck accepts 1/4" hex accessories only.
Place the switch in the locked off (center) position or remove battery pack before changing accessories.
To install an accessory, pull the chuck collar (c) away from the front of the tool, insert the accessory and release the collar. The accessory is locked in place.
To remove an accessory, pull the chuck collar away from the front of the tool. Remove the accessory and release the collar.

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.
Anvil With Detent Pin (fig. 5)
DC820, DC822, DC830, DC832, DC840
Place the switch in the locked off (center) position or remove battery pack before changing accessories.
To install a socket on the anvil, align the hole in the side of the socket with the detent pin (e) on the anvil (f). Press the socket on until the detent pin engages in the hole. Depression of detent pin may be necessary to aid installation of socket.
CAUTION: Use only impact sockets.
To remove a socket, depress the detent pin through the hole and pull the socket off.
Usage
Your impact tool generates the following output torque:
Cat # | Nm |
DC820 145 1740 195
DC822 145 1740 195
DC825 111 1330 150
DC827 111 1330 150
DC830 135 1620 180
DC832 135 1620 180
•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 fastening time results in increased fastening torque. Using a longer fastening time than recom- mended could cause the fasteners to be overstressed, stripped or damaged.
MAINTENANCE
Your DEWALT 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 regular cleaning.
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental
