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.

WARNING

To reduce the risk of injury,

always use a side handle when using this tool.
Always brace or hold securely.

ASSEMBLY

WARNING

To reduce the risk of injury,

always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.

Adjusting the Side Handle Position

1. Loosen the side handle by unscrewing the side

handle grip until the side handle rotates freely.

2. Rotate the side handle to the desired position.
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. The teeth
must match the orientation on the side handle
to properly lock in place.

NOTE:

The drilling depth is the distance between

the tip of the bit and the tip of the rod.

3. Release the clamping lever.

OPERATION

WARNING

To reduce the risk of injury,

always unplug tool before attaching or remov-
ing accessories or making adjustments. Use
only specifi cally recommended accessories.
Others may be hazardous.

WARNING

To reduce the risk of injury,

keep hands and cord away from the bit and
all moving parts.

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.

WARNING

To reduce the risk of injury,

wear safety goggles or glasses with side
shields.

3. Place the chuck key into

each of the three holes
in the chuck, turning it
clockwise to tighten the
chuck securely.

NOTE:

Never use a

wrench or means other
than a chuck key to tight-
en or loosen the chuck.

4. To remove the bit, insert

the chuck key into one of the holes in the chuck
and turn it counterclockwise.

Selecting Action
MILWAUKEE

Hammer-Drills have two settings:

drilling and hammer-drilling.

1. For

drilling

, push the hammer-drill lever over

the drill symbol .

2. For

hammer-drilling

, push the hammer-drill

lever over the hammer symbol .

NOTE:

To engage the hammering mechanism,

maintain pressure on the bit. When pressure on the
bit is released, the hammering action will stop.

Using Forward/Reverse Lever

The forward/reverse lever can only be adjusted
when the trigger is not pressed. Always allow the
motor to come to a complete stop before using the
forward/reverse lever.
1. For

forward

(clockwise) rotation, push the for-

ward/reverse lever to the
left (when viewed from
the back of the tool) as
shown.

2. For

reverse

(counter-

clockwise) rotation, push
the forward/reverse lever
to the right (when viewed
from the back of the tool) as shown. Allow the
motor to come to a full stop before reversing.

NOTE:

When hammer-drilling, use the tool in for-

ward rotation (clockwise) only.

Reverse

Starting, Stopping & Controlling Speed

1. To

start

the tool, pull trigger.

2. To

stop

the tool, release trigger.

3. To

vary

the speed, increase or decrease pres-

sure to trigger. The further the trigger is pulled,
the greater the speed.

Locking Trigger

The lock button holds the trigger in the ON position
for continuous full speed use.
1. To

lock

the trigger, hold in the lock button while

pulling the trigger. Release the trigger.

2. To

unlock

the trigger, pull the trigger and release.

The lock button will pop out.

Operating

Position the tool, grasp the handles fi rmly and pull
the trigger. Always hold the tool securely using both
handles and 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 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, stop the tool, free the bit and begin again.

WARNING

To prevent personal injury,

always remove the chuck key from the chuck
after each use.

Installing Bits into Keyed Chucks

Be sure that the shank of the bit and the chuck
jaws are clean. Dirt particles may cause the bit
to line up improperly. Do not use bits larger than
the maximum recommended capacity of the drill
because gear damage or motor overloading may
result. For best performance, be sure that the bits
are properly sharpened before use.
1. Unplug the tool.
2. Open the chuck jaws wide enough to insert a bit.

Allow the bit to strike the bottom of the chuck.
Center the bit in the chuck jaws and tighten the
jaws by hand to align the bit.
