OPERATION
Always remove battery pack before
WARNING
changing or removing accesso-
ries. Only use accessories specifically recom-
mended for this tool. Others may be hazardous.
To reduce the risk of injury, keep hands away
from the bit and all moving parts.
Always 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 use a side handle when using this tool.
Always brace or hold securely.
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 ar-
row points to the hammer and
twist drill symbol.
3. For hammering only, rotate
the mode selector so the arrow points to the ham-
mer 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, main-
tain 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 any time
the tool is not in use.
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(s) firmly and
pull the trigger.
NOTE: An LED is turned on when the trigger is
pulled and will go off shortly after the trigger is
released.
2. To vary the speed, increase or decrease the pres-
sure on the trigger. The further the trigger is pulled,
the greater the speed.
3. To stop the tool, release the trigger. Ensure the
tool has come 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.
The AUTOSTOP™ kickback control feature senses
a bind and when the tool turns too much in a bind up
situation, the electronics shut the tool off. There is
an onboard light that will blink when AUTOSTOP™
activates.
NOTE: Applying greater pressure does not increase
the tool's effectiveness. If the applied working pres-
sure is too high, the shock absorber will be pushed
together making the vibrations to the handle notice-
ably 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.
