EXTENSION CORDS
Grounded tools require a three wire extension
cord. Double insulated tools can use either a two
or three wire extension cord. As the distance from
the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with
inadequately sized wire causes a serious drop in
voltage, resulting in loss of power and possible tool
damage. Refer to the table shown to determine the
required minimum wire size.
The smaller the gauge number of the wire, the
greater the capacity of the cord. For example, a 14
gauge cord can carry a higher current than a 16
gauge cord. When using more than one extension
cord to make up the total length, be sure each cord
contains at least the minimum wire size required. If
you are using one extension cord for more than one
tool, add the nameplate amperes and use the sum
to determine the required minimum wire size.
Guidelines for Using Extension Cords
• If you are using an extension cord outdoors,
be sure it is marked with the suffi x "W-A" ("W"
in Canada) to indicate that it is acceptable for
outdoor use.
• Be sure your extension cord is properly wired
and in good electrical condition. Always replace
a damaged extension cord or have it repaired by
a qualifi ed person before using it.
• Protect your extension cords from sharp objects,
excessive heat and damp or wet areas.

ASSEMBLY
WARNING
To reduce the risk of injury,
always unplug tool before attaching
or removing accessories or making adjust-
ments. Use only specifi cally recommended
accessories. Others may be hazardous.
WARNING
To reduce the risk of injury,
always use a side handle when using
this tool. Always brace or hold securely.
Adjusting the Side Handle Position
16
1. Loosen the side handle by unscrewing the side
14
handle grip until the side handle rotates freely.
12
2. Rotate the side handle to the desired position.
12
3. Tighten the side handle grip securely.
Setting the Depth Gauge
1. Press in the clamping lever.
2. Slide the depth gauge rod backward or forward
until it is set for the desired depth.
NOTE: The drilling depth is the distance between
the tip of the bit and the tip of the rod.
3. Release the clamping lever.
WARNING
To reduce the risk of injury
do not grasp the bit while the chuck is rotat-
ing or while the bit is falling from the chuck.

Installing Drill Bits and Chisels
Only use accessories with SDS or SDS+ shanks.
Be sure that the shank of the bit is clean. Dirt par-

ticles may cause the bit to line up improperly. Do not
Twist Drill use bits larger than the maximum recommended
Bit (Steel)
capacity of the drill because gear damage or mo-
tor overloading may result. For best performance,
1/2"
be sure that the bit is properly sharpened and the
shank is lightly greased before use.
1. Insert the bit or chisel into the nose of the tool.

2. Rotate bit slowly until it aligns with the locking
mechanism.
WARNING

always unplug tool before attaching or remov-
ing accessories or making adjustments. Use

only specifi cally recommended accessories.
Others may be hazardous.
WARNING
wear safety goggles or glasses with side
shields.
WARNING
keep hands and cord away from the bit and
all moving parts.
Selecting Action
These MILWAUKEE Rotary Hammers have two
settings: drilling and rotary hammering.
Fig. 1
1. For drilling, turn the selector lever so the arrow
on the lever points to the twist drill symbol .
2. For rotary hammering, turn the selector lever so
the arrow points to the hammer and twist drill
symbol .
3. Push bit into tool until it locks.
4. Check that the bit is locked properly; it should
be possible to pull the bit back and forth slightly
(about 1/4").
5. To remove bits and chisels,
pull bit holder release collar
toward the rear of tool and
remove bit.
NOTE: Use caution when han-
dling hot bits and chisels.

OPERATION

Using the Control Switch
To reduce the risk of injury,
Due to a lockout mechanism, the control switch
can only be adjusted when the trigger is not pulled.
Always allow the motor to come to a complete stop
before using the control switch.
Fig. 2
Forward
To reduce the risk of injury,
To reduce the risk of injury,
For forward (clockwise) rotation, push the control
switch to the left side of the tool. Check the direction
of rotation before use.
For reverse (counterclockwise) rotation, push the
control switch to the right side of the tool. Check
direction of rotation before use.
Starting, Stopping and Controlling Speed
1. To start the tool, grasp the handle fi rmly and pull
the trigger.
2. To vary the speed, increase or decrease the
pressure on the trigger. The further the trigger
is pulled, the greater the speed.
3. To stop the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Operating
Position the tool, grasp the handles fi rmly and pull
the trigger. Always hold the tool securely using both
handles to maintain control. This tool has been
designed to achieve top performance with only
moderate pressure. Let the tool do the work.
If the speed begins to drop off when drilling large
or deep holes, pull the bit partially out of the hole
while the tool is running to help clear dust. Do not
use water to settle the dust since it will clog the bit
fl utes and tend to make the bit bind in the hole. If
the bit should bind, a built-in, non-adjustable slip
clutch prevents the bit from turning. If this occurs,
stop the tool, free the bit and begin again.
