MAINTENANCE
Your 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
start-up can causeinjury.
The charger and battery pack are notserviceable.
Usage (Fig. A)

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 variable speed trigger switch
3
to start operation.
Release variable speed trigger 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 recommended could cause the fasteners to
be overstressed, stripped ordamaged.
Modes 1and 2are optimized to match the installation speeds
of commonly used self‑drilling and tapping screws. Refer to the
impact driver manual and screw manufacturer instructions for
properinstallation.
NOTE: Select Mode 2when operating DeWALT IMPACT
CONNECTaccessories.
Specifications
Mode Application RPM
Mode 1 Low speed 0‑1800 forward
0‑1800 reverse
Mode 2 Medium speed 0‑2500 forward
0‑2500 reverse
Mode 3 High speed 0‑3800 forward
0‑3800 reverse
Mode 4 Flashlight mode
Worklight (Fig. A, C)

CAUTION: Do not stare into worklight. Serious eye
injury couldresult.
The worklight
8
comes with multiplesettings.
Pressing the worklight button
12
repeatedly will cycle
through low illumination for 20seconds, high illumination for
20seconds, high illumination for 20minutes, and off.
When the worklight icon is lit, the high illumination 20minute
LED mode isenabled.
NOTE: The worklight is for lighting the immediate work surface
and is not intended to be used as aflashlight.
Forward/Reverse Control Button (Fig. A)
A forward/reverse control button
4
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, release the trigger switch and depress the
forward/reverse control button on the left side of thetool.
The centre 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.
Variable Speed Trigger Switch (Fig. A)
To turn the tool on, squeeze the trigger switch
3
. To turn the
tool off, release the trigger switch. Your tool is equipped with
a brake. The anvil will stop when the trigger switch is fully
released. The variable speed switch enables you to select the
best speed for a particular application. The more you squeeze
the trigger, the faster the tool will operate. For maximum tool
life, use variable speed only for starting holes orfasteners.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should beavoided.
Proper Hand Position (Fig. E)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
suddenreaction.
Proper hand position requires one hand on the main
handle
11
.
before making any adjustments or removing/
installing attachments or accessories. An accidental
start-up can causeinjury.
Mode Selector (Fig. A, C)
Your tool is equipped with a mode selector
7
which allows you
to select one of three modes. Select the mode based on the
maximum speed/torque needed and control the speed of the
tool using the variable speed trigger
3
.
