WARNING To reduce the risk of injury, do not grasp the bit while the chuck is rotating or while the bit is falling from the chuck.

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.

APPLICATIONS

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 operating mode. Use high speed steel twist drills or hole saws. Use a center punch to start the hole. Lubri- cate drill bits with cutting oil when drilling in iron

MAINTENANCE

WARNING To reduce the risk of injury, always unplug your tool before performing any maintenance. Never disas- semble the tool or try to do any rewiring on the tool’s electrical system. Contact a MILWAUKEE service facility for ALL repairs.

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

WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only speciﬁcally recommended accessories. Others may be hazardous.

WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields.

WARNING To reduce the risk of injury, keep hands and cord away from the bit and all moving parts.

Selecting Action

MILWAUKEE Hammer-Drills have two settings: drilling and hammer-drilling.

1.For drilling, turn the hammer-drill lever towards the drill symbol .

2.For hammer-drilling, turn the hammer-drill lever

towards the hammer symbol

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

The forward/reverse lever can only be adjusted when the trigger is not pressed. Always allow the motor to come to a complete stop before using the forward/reverse lever.

1. For forward (clockwise) rotation, push the con- trol switch to the left side of the tool . Check the direction of rotation before use.

2. For reverse (counterclockwise) rotation, push the control switch to the right side of the tool . Check direction of rotation before use.

NOTE: When hammer-drilling, use the tool in for- ward rotation (clockwise) only.

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.

Locking Trigger

The lock button holds the trigger in the ON position for continuous full speed use.

1.To lock the trigger, hold in the lock button while pulling the trigger. Release the trigger.

2.To unlock the trigger, pull the trigger and release. The lock button will pop out.

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.

the material to prevent binding and distortion on breakthrough.

Drilling in Masonry

When drilling in masonry, select the rotary hammer operating mode. Use high speed carbide-tipped bits. Drilling soft masonry materials such as cinder block requires little pressure. Hard materials like concrete require more pressure. A smooth, even ﬂow of dust indicates the proper drilling rate. Do not let the bit spin in the hole without cutting. Do not use water to settle dust or to cool bit. Do not attempt to drill through steel reinforcing rods. Both actions will damage the carbide.

ACCESSORIES

WARNING To reduce the risk of injury, always unplug the tool before attaching or removing accessories. Use only speciﬁcally recommended accessories. Others may be hazardous.

For a complete listing of accessories refer to your MILWAUKEE Electric Tool catalog or go on-line to www.milwaukeetool.com. To obtain a catalog, contact your local distributor or a service center.

ken parts and any other condition that may affect its safe operation. If abnormal noise or vibration occurs, 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 neces- sary 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 electri- cal operation

WARNING To reduce the risk of injury, electric shock and damage to the tool, never immerse your tool in liquid or allow a liquid to ﬂow inside the tool.

Cleaning

Clean dust and debris from vents. Keep the tool handles clean, dry and free of oil or grease. Use only mild soap and a damp cloth to clean your tool since certain cleaning agents and solvents are harmful to plastics and other insulated parts. Some of these include: gasoline, turpentine, lacquer thin- ner, paint thinner, chlorinated cleaning solvents, ammonia and household detergents containing ammonia. Never use ﬂammable or combustible solvents around tools.

Repairs

If your tool is damaged, return the entire tool to the nearest service center.
