NOTE: To engage the hammering mechanism, maintain pressure on the bit. When pressure on the bit is released, the hammering action will stop.
Using Forward/Reverse Lever (Fig. 6)
The forward/reverse lever can only be adjust- ed when the trigger is not pressed. Always allow the motor to come to a complete stop before using the forward/reverse lever.

Forward
1.For forward (clockwise) rotation, push the forward/reverse lever to the left (when viewed from the back of the tool) as shown.
2.For reverse (counterclockwise) rotation, push the forward/reverse lever to the right (when viewed from the back of the tool) as shown. Allow the motor to come to a full stop before reversing.
NOTE: When
Selecting Speed
The speed can be changed when the tool is at a complete stop or running under no load.
1.For low speed (up to 1350 rpm), turn the speed selector to position 1.
2.For high speed (up to 2500 rpm), turn the speed selector to position 2.
Starting, Stopping & Controlling Speed
1.To start the tool, pull trigger.
2.To stop the tool, release trigger.
3.To vary the speed, increase or decrease pressure to trigger. The further the trig- ger is pulled, the greater the speed.
Operating
Position the tool, grasp the handles firmly and pull the trigger. Always hold the tool securely using both handles and 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 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.
WARNING
To reduce the risk of electric shock, check work area for hidden pipes and wires before drilling.
Drilling in Wood, Composition Materials and Plastic
When drilling in wood, composition materials and plastic, select the drill operating mode. Start the drill slowly, gradually increasing speed as you drill. Select low speeds for plastics with a low melting point.
Drilling in Metal
When drilling in metal, select the drill operat- ing mode. Use high speed steel twist drills or hole saws. Use a center punch to start the hole. Lubricate drill bits with cutting oil when drilling in iron or steel. Use a coolant when drilling in nonferrous metals such as copper, brass or aluminum. Back the ma- terial to prevent binding and distortion on breakthrough.
Drilling in Masonry
When drilling in masonry, select the ham-

Maintaining Tools
Keep your tool in good repair by adopting a regular maintenance program. Before use, examine the general condition of your tool. Inspect guards, switches, tool cord set and extension cord for damage. Check for loose screws, misalignment, binding of moving parts, improper mounting, broken parts and any other condition that may affect its safe operation. If abnormal noise or vibration oc- curs, turn the tool off immediately and have the problem corrected before further use. Do not use a damaged tool. Tag damaged tools “DO NOT USE” until repaired (see “Repairs”).
Under normal conditions, relubrication is not necessary until the motor brushes need to be replaced. After six months to one year, depending on use, return your tool to the nearest MILWAUKEE service facility for the following:
•Lubrication
•Brush inspection and replacement
•Mechanical inspection and cleaning (gears, spindles, bearings, housing, etc.)
•Electrical inspection (switch, cord, armature, etc.)
•Testing to assure proper mechanical and electrical operation
