Drilling Depth

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 depth gauge rod.

3.  Release the clamping lever.

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.

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.

For use with the Dust Extractor
The Milwaukee Cat. No. 2715-DE Dust Extractor 
plugs directly into these 1-1/8" SDS PLUS 

1-1/8" SDS PLUS Rotary 

Rotary 

Hammers. 

Hammers. For Dust Extractor assembly and opera-
tion, refer to your Dust Extractor manual.

Installing Drill Bits and Chisels
NOTE: Only use accessories with SDS or SDS 
Plus shanks.
Be sure that the shank of the bit is clean. Dirt par-
ticles 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 mo-
tor overloading may result. For best performance, 
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.

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 handling hot bits and 
chisels.

Starting, Stopping and Controlling Speed
For operation when using the Dust Extractor, refer 
to your Dust Extractor manual.
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.

Selecting Action 
MILWAUKEE Rotary Hammers have three settings: 
rotation only, rotary hammer, and hammer only. 
Always allow the motor to come to a complete 
stop before changing the mode selection to avoid 
damage to the tool.
1. For rotation only, rotate the 

mode selector so the arrow 
on the lever points to the 
twist drill  symbol. 

2. For rotary hammering, 

rotate the mode selector 
so the arrow points to the 
hammer and twist drill
symbol.

3. For hammering only, rotate the mode selector 

so the arrow points to the hammer symbol.

4. To freely rotate the bit to the desired angle for 

hammering only, rotate the mode selector to the

symbol. Then, follow step 3.

NOTE:   To engage the hammering mechanism, 
maintain pressure on the bit. When pressure on 
the bit is released, the hammering action will stop.

Using the Control Switch
The control switch may be set to three positions: 
forward, reverse and lock. Always allow the motor 
to come to a complete stop before using the control 
switch to avoid damage to the tool.
For forward (clockwise) rotation, push in the control 
switch from the right side of the tool. Check the 
direction of rotation before use.
For reverse (counterclockwise) rotation, push in the 
control switch from the left side of the tool. Check 
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.

Operator Force
The Anti-Vibration System provides the operator 
with comfort without sacrifi cing power or perfor-
mance. 
Ideal operator force compresses the bellows slightly 
and allows the tool to work aggressively while the 
handle remains steady. 
Excessive force compresses the bellows signifi -
cantly and reduces vibration dampening. Users will 
be able to feel the difference and should adjust the 
force to the handle accordingly.
