Attaching Right Angle Drive to a Drill
1. Remove the chuck from the drill fol-
lowing instructions (see “Removing
the Chuck from the Drill”). Slip the
double hex coupling (1) over the hex
on the drill spindle.
Loosen the clamping screws on
the clamping sleeve (2) and slip the
sleeve onto the drill collar.
2. Slide the right angle drill head (3)
into the other side of the sleeve
and turn the drive head slightly in
either direction so the hexagonal
hole in the coupling engages the
hexagonal portion of the spindle.
NOTE:
Attaching the drill chuck to the side des-
ignated “low” reduces the speed by 1/3, or 33%.
Attaching the drill chuck to the opposite side of
the right angle drill head increases the speed by
1/2, or 50%.
3. When assembled, turn the right angle head to the
desired position and tighten the clamping screws
to secure the unit. Thread the chuck onto the right
angle drive spindle and install the chuck screw.
Removing the Chuck from the RAD
The chuck can be removed
from the right angle drive
unit in the same manner
it is removed from the
drill; however, ALWAYS
REMOVE RIGHT ANGLE
DRIVE FROM THE DRILL
BEFORE ATTEMPTING
TO LOOSEN THE CHUCK.
This will prevent damaging
the drill's gearing. Use the open end wrench pro-
vided to hold the right angle drive spindle before
attempting to loosen the chuck.
Removing the Chuck from the Drill
1. To remove the left-hand
screw inside the chuck,
remove the battery pack
from the tool and open
the chuck jaws. Insert a
T-handle hex key into the
screw inside the chuck.
Turn the T-handle hex key
and remove the screw.
Save the screw for install-
ing your new chuck.
2. To remove chuck: Tighten
a large hex key into the chuck. Place the chuck
on a workbench as shown. Strike the hex key
with a soft-headed mallet to loosen the chuck.
Remove the chuck by hand.

ASSEMBLY
WARNING
Recharge only with the char-
ger specifi ed for the battery. For specifi c charg-
ing instructions, read the operator’s manual
supplied with your charger and battery.
WARNING
Always remove battery
pack before changing or removing acces-
sories. Only use accessories specifically
recommended for this tool. Others may be
hazardous.
Removing Battery Pack from Tool
Push in the release buttons and pull the battery
pack away from the tool.
Inserting Battery Pack into Tool
To insert the battery pack onto the tool, slide the
pack onto the body of the tool. Make sure it latches
securely into place.
WARNING
To reduce the risk of injury,
always use a side handle when using this tool.
This tool operates with high torque. Always
brace or hold the tool securely.
WARNING
When using the D-handle
drill without the right angle drive unit, do
not clamp the ring clamp with attached side
handle to the front of the gear case; use the
side handle instead.
Do not use the extension when using the
ring clamp.
Ring Clamp, Extension, and Side Handle for
Right Angle Drive (RAD)
For D-handle drill with RAD:
A ring clamp, extension, and side handle are sup-
plied with the Right Angle Drive Unit. When using a
right angle drive unit, attach the side handle to the
ring clamp. Do not use the extension when using
the ring clamp. The ring clamp with attached side
handle clamps onto the right angle drive unit and
can swivel 360° and locked tight in any position.
For D-handle drill without RAD:
When using the D-handle drill without the right
angle drive unit, remove the ring clamp with at-
tached side handle from the RAD, then remove
the side handle from the ring clamp. Attach the
side handle to the extension. The side handle can
be installed on either side of the tool for right or left
handed use. To install the extension with attached
side handle, thread it into the socket on the desired
side of the tool (for right or left-handed use) and
tighten securely.
NOTE:
If you have an extra ring clamp with at-
tached side handle and extension with attached
side handle, do not use the extension with attached
side handle when using the right angle drive unit.
Remove it from the tool.

SERVICE
• Have your power tool serviced by a qualifi ed
repair person using only identical replacement
parts.
This will ensure that the safety of the power
tool is maintained.
SPECIFIC SAFETY RULES
•
Use auxiliary handle(s), if supplied with the
tool.
Loss of control can cause personal injury.
•
Hold power tool by insulated gripping
surfaces, when performing an operation
where the cutting accessory may contact
hidden wiring.
Cutting accessory contacting a
“live” wire may make exposed metal parts of the
power tool “live” and could give the operator an
electric shock.
• Maintain labels and nameplates.
These carry
important information. If unreadable or missing,
contact a
MILWAUKEE
service facility for a free
replacement.
• WARNING
Some dust created by power sanding,
sawing, grinding, drilling, and other construction
activities contains chemicals known to cause
cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paint
• crystalline silica from bricks and cement and
other masonry products, and
• arsenic and chromium from chemically-treated
lumber.
Your risk from these exposures varies, depending
on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well
ventilated area, and work with approved safety
equipment, such as those dust masks that are spe-
cially designed to fi lter out microscopic particles.
• Use power tools only with specifi cally desig-
nated battery packs.
Use of any other battery
packs may create a risk of injury and fi re.
• When battery pack is not in use, keep it away
from other metal objects, like paper clips,
coins, keys, nails, screws or other small metal
objects, that can make a connection from one
terminal to another.
Shorting the battery terminals
together may cause burns or a fi re.
• Under abusive conditions, liquid may be eject-
ed from the battery; avoid contact. If contact
accidentally occurs, fl ush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation
or burns.
