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.

3. Place the chuck key 

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

Never use a wrench or means other than 

a chuck key to tighten or loosen the chuck.

4. To remove the bit, insert the chuck key into one 

of the holes in the chuck and turn it counterclock-
wise.

Selecting Action
MILWAUKEE  Hammer-Drills have two settings: 
drilling and hammer-drilling.  
1. For drilling, slide the hammer-

drill lever to display the drill 
symbol  . 

2. For hammer-drilling, slide the 

hammer-drill lever to display the 
hammer symbol  .

To engage the ham-

mering mechanism, maintain 
pressure on the bit. When pressure on the bit is 
released, 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. When hammer-drilling, use 
the tool in forward rotation (clockwise) only.
1.  For forward (clockwise) rotation, slide the  for-

ward/reverse lever display the forward symbol 

 .

2.  For  reverse  (counterclockwise) rotation, slide 

the  forward/reverse lever display the reverse 
symbol   .

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 wa-
ter 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 
activates. If this occurs, stop the tool, free the bit 
and begin again.

Adjusting the Side Handle Position and setting 
the Depth Gauge
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. Slide the depth gauge rod to the desired position.

The drilling depth is the distance between the tip 
of the bit and the tip of the rod.

4.  Tighten the side handle grip securely.
