Forward/Reverse Control Button (fig. 1)

A forward/reverse control button (b) determines the direction of the tool and also serves as a lock off button.

To select forward rotation, release the trigger switch and depress the forward/reverse control button on the right side of the tool.

To select reverse, depress the forward/reverse control button on the left side of the tool.

The center position of the control button locks the tool in the OFF position. When changing the position of the control button, be sure the trigger is released.

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.

Worklight (fig. 1)

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.

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. Non-impact sockets may break and cause a hazardous condition. Inspect socket prior to use to ensure that it contains no cracks.

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 #

Ft.-Lbs. In.-Lbs.

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

DC835 103 1240 140

DC837 103 1240 140

DC840 120 1440 160

DC845 96 1150 130

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.
