hanger.
2. Position the tool hanger on the tool over the two
screw holes.
3. Insert the two screws. Hand tighten the screws.
4. To remove, reverse the procedure.
Only use accessories specifically
WARNING
recommended for this tool. Others
may be hazardous.
Use only sockets and other accessories specifi-
cally designed for use on impact wrenches. Other
sockets and accessories might shatter or break
causing injury.
Attaching and Removing Accessories
1/2" Impact Wrench with Pin Detent
(Cat. No. 2966-20)
1. WARNING! Remove battery to avoid starting the tool.
2. Use only the appropriate size Square Drive Sockets.
3. To attach a socket, align the hole in the accessory
with the detent pin on the anvil. Hold the detent
pin in while pushing the socket onto the anvil.
The detent pin will snap into place in the hole to
secure the socket.
4. To remove the socket, insert a nail or other thin
object into the hole in the accessory and press
in the detent pin. Pull the accessory off the anvil.
1/2" Impact Wrench with Friction Ring
(Cat. No. 2967-20)
1. WARNING! Remove battery to avoid starting the tool.
2. Use only the appropriate size Square Drive Sockets.
3. To attach a socket, align the accessory with the
anvil and push it firmly over the retaining ring.

the anvil.

OPERATION

To reduce the risk of injury, always
WARNING
wear proper eye protection marked
to comply with ANSI Z87.1.
Using the Drive Control
The drive control button is used to adjust the torque,
rotation speed (RPM), and impact speed (IPM) for
the application.
To select the drive control mode: Drive Control Button
1. Pull and release the trigger
to turn on the tool. The cur-
rent mode indicator is lit.
2. Press the drive control but-
ton to cycle through the
4 modes. When the desired

*Torque values depend on many factors such as state
of battery discharge, battery size, impacting time, bolt
size, etc. Always check with a torque wrench to ensure
desired torque value is achieved. This is not a precision
fastening tool.
Auto Shut-Off Mode
†
In mode, when run in reverse, the tool will spin
at the above RPM and IPM until the nut breaks free
from the joint. Then, the tool slows to 750 RPM for
better control in removing the nut.
Using the Control Switch
The control switch may be set to three positions:
forward, reverse and lock. Due to a lockout mecha-
nism, the control switch can only be adjusted when
the ON/OFF switch is not pressed. Always allow the
motor to come to a complete stop before using the
control switch.
For forward (clockwise) rotation, push in the control
from the right side of the tool. Check the
switch
direction of rotation before use.
For reverse (counterclockwise) rotation, push in the
from the left side of the tool. Check
control switch
direction of rotation before use.
To lock the trigger, push the control switch to the
center position. The trigger will not work while the
control switch is in the center locked position. Always
lock the trigger or remove the battery pack before
performing maintenance, changing accessories,
storing the tool and any time the tool is not in use.
Nut-Busting
Starting, Stopping and Controlling Speed
Torque
1. To start the tool, grasp the handle(s) firmly and
(ft-lbs)
pull the trigger.
Up to 350*
NOTE: An LED is turned on when the trigger is
pulled and will go off shortly after the trigger is
Up to 750*
released.
Up to 1100*
2. To vary the speed, increase or decrease the pres-
sure on the trigger. The further the trigger is pulled,
the greater the speed.
3. To stop the tool, release the trigger. Ensure the
Up to 1100*
tool has come to a complete stop before laying
the tool down.
Impacting Techniques
The longer a bolt, screw, or nut is impacted, the
Fastening Nut-Busting
tighter it will become. To help prevent damaging the
Torque Torque
fasteners or workpieces, avoid excessive impact-
(ft-lbs) (ft-lbs)
ing. Be particularly careful when impacting smaller
Up to 650*
fasteners because they require less impacting to
reach optimum torque.
Up to 900*
Practice with various fasteners, noting the length of
Up to 1100 Up to 1500
time required to reach the desired torque. Check the
w/ XC5.0Ah w/ XC5.0Ah
tightness with a hand-torque wrench. If the fasteners
battery* battery*
are too tight, reduce the impacting time. If they are
Up to 1200 Up to 1600
not tight enough, increase the impacting time.
w/ FORGE™ w/ FORGE™
Oil, dirt, rust or other matter on the threads or under the
battery* battery*
head of the fastener affects the degree of tightness.
Up to 1500
The torque required to loosen a fastener averages
w/ XC5.0Ah
75% to 80% of the tightening torque, depending on
battery*
the condition of the contacting surfaces.
†
Up to 1600
On light gasket jobs, run each fastener down to a
w/ FORGE™
relatively light torque and use a hand torque wrench
battery*
for final tightening.
To reduce the risk of injury, always
WARNING
unplug the charger and remove the
battery pack from the charger or tool before
performing any maintenance. Never disassemble
the battery pack, charger, or tool, except as pro-
vided in these instructions. Contact a MILWAUKEE
service facility for all other repairs.
Keep your tool, battery pack and charger in good
repair by adopting a regular maintenance program.
Inspect your tool for issues such as undue noise,
misalignment or binding of moving parts, breakage of
parts, or any other condition that may affect the tool
operation. Return the tool, battery pack, and charger
to a MILWAUKEE service facility for repair. After six
months to one year, depending on use, return the
tool, battery pack and charger to a MILWAUKEE
service facility for inspection.
If the tool does not start or operate at full power with
a fully charged battery pack, clean the contacts on
the battery pack. If the tool still does not work prop-
erly, return the tool, charger and battery pack, to a
MILWAUKEE service facility for repairs.
To reduce the risk of personal in-
WARNING
jury and damage, never immerse
your tool, battery pack or charger in liquid or
allow a liquid to flow inside them.
Clean dust and debris from any vents. Keep tool
clean, dry and free of oil or grease. Use only mild
soap and a damp cloth to clean, since certain clean-
ing agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household deter-
gents containing ammonia. Never use flammable or
combustible solvents around tools.
For repairs, return the tool, battery pack and charger
to the nearest authorized service center.
Use only recommended accesso-
