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 dam-

age 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 

the pressure on the bit is released, the hammering 

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 direc

-

tion 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.

3. To 

stop

 the tool, release the trigger. Make sure 

the tool comes to a complete stop before laying 

the tool down.

Drilling Depth

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 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 overload-

ing may result. For best performance, be sure that 

the bit is properly sharpened and the shank is lightly 

greased before use.

possible to pull the bit back and forth slightly (about 

6 mm (1/4")

.

6. To remove bits and chisels, pull bit holder release 

collar toward the rear of tool and remove bit.
