ASSEMBLY
To reduce the risk of injury, always
WARNING
unplug tool before changing or
removing accessories. Only use accessories
specifically recommended for this tool. Others
may be hazardous.
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
1. Loosen the side handle by unscrewing the side
handle kbob until the side handle rotates freely.
2. Rotate the side handle to the desired position.
3. Tighten the side handle knob securely.
Installing Bits and Chisels
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 recom-
mended capacity of the drill because gear damage
or motor overloading may result. For best perfor-
mance, be sure that the bit is properly sharpened
and the shank is lightly greased before use.
Use caution when handling hot bits and chisels.
SDS-Max Drive System
1. Unplug tool.
2. Insert the bit or chisel into the nose of the tool.
3. Push bit into tool until it locks.
4. Check to see that the bit is locked by tugging on it.

WARNING
wear proper eye protection marked
to comply with ANSI Z87.1.
When working in dusty situations, wear appro-
priate respiratory protection or use an OSHA
compliant dust extraction solution.
Always unplug tool before attaching or removing
accessories or making adjustments. Use only
specifically recommended accessories. Others
may be hazardous.
Keep hands away from the bit and moving parts.
Always use a side handle when using this tool.
Always brace or hold securely.
Selecting Action
These MILWAUKEE Rotary Hammers
have three settings: hammering with
rotation, hammering-only, and chisel
adjustment.
1. Hammering with rotation. Use this
setting for drilling holes with drill
bits.
2. Hammering only. For use with
"hammering-only" accessories. Use
this setting for chiseling or setting
self-drilling anchors.
3. Chisel adjustment. Use this setting
to adjust the angle of the chisel
blade in relation to the tool. With a
chisel mounted in the tool:
• turn the knob to this setting
• rotate the chisel to the desired
angle
• turn the knob to "hammering-only".
NOTE: To engage the hammering mechanism, main-
tain pressure on the bit. When the pressure on the bit
is released, the hammering will stop.

Starting and Stopping

1. To start the tool, grasp the handle firmly and pull
the trigger.
2. To stop the tool, release the trigger. Make sure
the tool comes to a complete stop before laying
the tool down.
Using the Chisel Lock
To activate the chisel lock:
1. Set the tool to chisel mode.
2. Pull and hold the trigger while sliding the chisel
lock button to the left.
3. Release trigger.
To deactivate the chisel lock, pull the trigger again.
Momentary
on
Position the tool, grasp the handles firmly and pull
the trigger. Always hold the tool securely using both
handles to maintain control. This tool has been de-
signed to achieve top performance with only moder-
ate 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 flutes 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.
NOTE: The tool will shut off and the service indicator
will flash if the handle begins to rotate during use.
Cycle through the trigger to continue operating.
Applying greater pressure does not
WARNING
increase the tool's effectiveness.
If the applied working pressure is too high, the
shock absorber will be pushed together making
the vibrations to the handle noticeably stronger.
Operator Force
The Anti-Vibration System provides the operator with
comfort without sacrificing power or performance.
Ideal operator force compresses the bellows slightly
and allows the tool to work aggressively while the
handle remains steady.
Excessive force compresses the bellows significantly
and reduces vibration dampening. Users will be able
to feel the difference and should adjust the force to
the handle accordingly.
