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 damage to the tool.
1. For rotation only, rotate the mode selector so the
arrow on the lever points to .
2. For rotary hammering, rotate the mode selector so
the arrow points to .
3. For hammering only, rotate the mode selector so the
arrow points to .
4. To freely rotate the bit to the desired angle for
.
hammering only, rotate the mode selector to
Then, follow step 3.
NOTE: To engage the hammering mechanism, maintain
.
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 and remove the battery pack before performing
maintenance, changing accessories, storing the tool and
any time the tool is not in use.
Starting, stopping and controlling speed
1. To start the tool, grasp the handle firmly and pull
the trigger.
2. To vary the speed, increase or decrease the pressure
on the trigger. The further the trigger is pulled, the
greater the speed.
3. To stop the tool, release the trigger. Make sure the
tool comes to a complete stop before laying the tool
down.
Operating
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 designed to
achieve top performance with only moderate 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.
