of the tool. Make sure it latches securely into place.
To reduce the risk of injury, always
WARNING
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 grip until the side handle rotates freely.
2. Rotate the side handle to the desired position.
3. Tighten the side handle grip 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 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. Use caution when handling hot
bits and chisels.
SDS-Max Drive System
1. Remove battery pack
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.
5. To remove bits and chisels, pull back on the bit
release collar and remove bit.
OPERATION
Always remove battery pack before
WARNING
changing or removing accessories.
Only use accessories specifically recommended
for this tool. Others may be hazardous.
To reduce the risk of injury, wear safety goggles
or glasses with side shields.
To reduce the risk of injury, keep hands away from
the bit and moving parts.
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.
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.
Cold Starting
If this tool is stored for a long period of time or
at cold temperatures, it may not hammer ini-
tially because the lubrication has become stiff.
To warm up the tool:
1. Insert and lock a bit or chisel into the tool.
2. Pull the trigger and apply force to the bit or chisel
against a concrete or wood surface for a few
seconds. Release the trigger
3. Repeat until the tool starts hammering. The colder
the tool is, the longer it will take to warm up.
Using Rotary Percussion Core Bits
Core Bits are useful for drilling large or long holes
in concrete. MILWAUKEE Heavy-Duty Core Bits
have heat-treated steel bodies with durable carbide
tips. These core bits are specially designed for fast,
accurate drilling with combined hammering and
rotary action.
1. Clean and lubricate the
threads on the adapter
and core bit to make
later removal easier.
Thread the adapter
shank to the rear of the
core bit.
2. Push the guide plate
onto the pointed end of
the center pin. Insert the
center pin and guide
plate assembly into the
core bit. Be sure the
small end of the center
pin is securely placed
into the hole in the cen-
ter of the core bit.
For LHS systems, screw
the threaded end of the
centering bit into the core bit.
NOTE: If using an extension, first thread the
adapter shank to the extension. Then thread the
core bit to the extension.
3. Insert the adapter into the nose of the tool as
described in "Installing Bits and Chisels". Set the
knob to the "hammering with rotation" setting.
