ASSEMBLY
WARNING Recharge only with the charger specified for the battery. For spe- cific charging instructions, read the operator’s manual supplied with your charger and battery.
WARNING Always remove battery pack before changing or removing acces- sories. Only use accessories specifically recommended for this tool. Others may be hazardous.
Removing Battery Pack from Tool
Push in the release buttons and pull the battery pack away from the tool.
Inserting Battery Pack into Tool
To insert the battery pack onto the tool, slide the pack onto the body of the tool. Make sure it latches securely into place.
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.
For use with the Dust Extractor
The Milwaukee Cat. No.
Setting the Depth Gauge
1.Press in the clamping lever.
2.Slide the depth gauge rod backward or forward until it is set for the desired depth.
NOTE: The drilling depth is the distance between the tip of the bit and the tip of the depth gauge rod.
3.Release the clamping lever.

Installing Drill Bits and Chisels
NOTE: Only use accessories with SDS or SDS Plus shanks.
Be sure that the shank of the bit is clean. Dirt par- ticles 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 mo- tor overloading may result. For best performance, be sure that the bit is properly sharpened and the shank is lightly greased before use.
1.Insert the bit or chisel into the nose of the tool.
2.Rotate bit slowly until it aligns with the locking mechanism.
3.Push bit into tool until it locks.
4.Check that the bit is locked properly; it should be possible to pull the bit back and forth slightly (about 1/4").
5.To remove bits and chisels, pull bit holder release collar toward the rear of tool and remove bit. NOTE: Use caution when handling hot bits and chisels.
OPERATION
WARNING Always remove battery pack before changing or removing acces- sories. Only use accessories specifically recommended for this tool. Others may be hazardous.
WARNING To reduce the risk of injury, keep hands away from the bit and all moving parts. Always wear safety goggles or glasses with side shields.
WARNING To reduce the risk of injury, 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 damage 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 arrow points to the 
hammer and twist drill 
symbol.
3.For hammering only, rotate the mode selector so the arrow points to the hammer 
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, maintain pressure on the bit. When pressure on the bit is released, the hammering action will stop.
Using the Control Switch
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 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
WARNING Applying greater pressure does not 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
Ideal operator force compresses the bellows slightly and allows the tool to work aggressively while the handle remains steady.
Excessive force compresses the bellows signifi- cantly and reduces vibration dampening. Users will be able to feel the difference and should adjust the force to the handle accordingly.
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 before performing maintenance, changing accessories, storing the tool and any time the tool is not in use.
