Cleaning

WARNING: Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
C
Lubrication
Your power tool requires no additionallubrication.
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.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
beavoided.
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 and Forward/Reverse
Control Button (Fig. A)
The tool is turned on and off by pulling and releasing the
variable speed trigger
1
. The farther the trigger is depressed,
the higher the speed of the tool. Your tool is equipped with
a brake. The chuck will stop as soon as the trigger switch is
fullyreleased.
A forward/reverse control button
4
determines the rotational
direction of the tool and also serves as a lock‑offbutton.
• To select forward rotation (clockwise), release the trigger
and depress the forward/reverse control button on the right
side of thetool.
• To select reverse (counterclockwise), depress the forward/
reverse control button on the left side of thetool.
NOTE: 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.
Inserting and Removing the Battery Pack
from the Tool (Fig. B)
NOTE: Make sure your battery pack
1
is fullycharged.
To Install the Battery Pack into the Tool Handle
1. Align the battery pack
1
with the rails inside the tool’s
handle (Fig. B).
2. Slide it into the handle until the battery pack is firmly seated
in the tool and ensure that you hear the lock snap intoplace.
To Remove the Battery Pack from the Tool
1. Press the release button
2
and firmly pull the battery pack
out of the toolhandle.
2. Insert battery pack into the charger as described in the
charger section of thismanual.
Fuel Gauge Battery Packs (Fig.B)
Some DeWALT battery packs include a fuel gauge which
consists of three green LED lights that indicate the level of
charge remaining in the batterypack.
To actuate the fuel gauge
9
, press and hold the fuel gauge
button. A combination of the three green LED lights will
illuminate designating the level of charge left. When the level
of charge in the battery is below the usable limit, the fuel gauge
will not illuminate and the battery will need to berecharged.
NOTE: The fuel gauge is only an indication of the charge left on
the battery pack. It does not indicate tool functionality and is
subject to variation based on product components, temperature
and end‑userapplication.
Proper Hand Position (Fig. C)

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
