Mode Selector (Fig. A, D)
Your tool is equipped with a mode selector
9
which allows
you to select one of three speeds or Precision Wrench™
mode. Select the mode based on the maximum speed/
torque needed and control the speed of the tool using the
variable speed trigger switch
1
.
Precision Wrench™ (Fig. D)
In addition to normal impacting modes, this tool features
the Precision Wrench™ mode which grants the user greater
control in both fastening and loosening applications.
When set in forward, the tool will fasten at 2000RPM until
impact begins. The tool will then pause for 0.5 seconds
before continuing to impact at a rate of 3250IPM, providing
the user with greater control and reducing the chance of
overtightening or damagingmaterial.
When set in reverse, the tool will impact at a normal speed
and rate of 3250IPM. Upon sensing that the fastener has
broken free, the tool will cease to impact and will reduce
speed to help prevent “run-off” of loosehardware.

Wall Mounting
Some DEWALT chargers are designed to be wall mountable
or to sit upright on a table or work surface. If wall mounting,
locate the charger within reach of an electrical outlet, and
away from a corner or other obstructions which may impede
air flow. Use the back of the charger as a template for the
location of the mounting screws on the wall. Mount the
charger securely using drywall screws (purchased separately)
at least 1” (25.4mm) long, with a screw head diameter of
0.28–0.35” (7–9mm), screwed into wood to an optimal
depth leaving approximately 7/32” (5.5 mm) of the screw
exposed. Align the slots on the back of the charger with the
exposed screws and fully engage them in theslots.
SAVE THESE INSTRUCTIONS FOR
FUTURE USE
a. Check operation of receptacle by plugging in a lamp
or other appliance;
b. Check to see if receptacle is connected to a light
switch which turns power off when you turn out
the lights;
c. If charging problems persist, take the tool, battery
pack and charger to your local servicecenter.
4. You may charge a partially used pack whenever you
desire with no adverse effect on the batterypack.
