GENERAL POWER TOOL SAFETY WARNINGS

WARNING Read all safety warnings, instruc-tions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

WORK AREA SAFETY.

• Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
• Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
• Keep children and bystanders away while oper-ating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

• Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
• Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet condi-tions. Water entering a power tool will increase the risk of electric shock.
• Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
• When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. The use of a GFCI reduces the risk of electric shock.

PERSONAL SAFETY

• Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
• If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust-related hazards.
• Do not let familiarity gained from the frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

POWER TOOL USE AND CARE

• Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
• Store idle power tools out of the reach of chil-dren and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use? Many accidents are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
• Use the power tool, accessories, tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

BATTERY TOOL USE AND CARE

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
• Use power tools only with specifically designed battery packs. Use of any other battery packs may create a risk of injury and fire.
• When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects,

Fuel Gauge

To determine the amount of charge left in the battery, turn the tool ON. The Fuel Gauge will light up for 2-3 seconds. When less than 10% of charge is left, 1 light on the fuel gauge will flash 4 times.
To signal the end of charge, 1 light on the fuel gauge will flash 8 times and the tool will not run. Charge the battery pack.
If the battery becomes too hot, the fuel gauge lights will flash and the tool will not run. Allow the battery to cool down.

Installing/Removing Bits

Always remove the battery before inserting or removing bits. Select the proper style and size bit for the job. This tool is equipped with a spindle lock. The chuck can be tightened with one hand, creating higher grip strength on the bit.

1. To open the chuck jaws, turn the collar in the counterclockwise direction.
   When using drill bits, allow the bit to strike the bottom of the chuck. Center the bit in the chuck jaws and lift it about 1/16″ off of the bottom. When using screwdriver bits, insert the bit far enough for the chuck jaws to grip the hex of the bit.

2. To close the chuck jaws, turn the sleeve in a clockwise direction. The bit is secure when the chuck makes a ratcheting sound and the sleeve can not be rotated any further.

3. To remove the bit, turn the collar in the counterclockwise direction.

NOTE: A ratcheting sound may be heard when the chuck is opened or closed. This noise is part of the locking feature and does not indicate a problem with the chuck’s operation.

Selecting Drill or Drive Action

1. To use the drilling mode, rotate the torque selector collar until the drill symbol appears in line with the arrow.
2. To use the driving mode, rotate the torque selector collar until the desired clutch setting appears in line with the arrow.
   The adjustable clutch, when properly adjusted, will slip at a preset torque to prevent driving the screw too deep into different materials and to prevent damage to the screw or tool.

Selecting Hammer, Drill or Drive Action (Cat. No. 3404-20)

1. To use the hammer-drilling mode, rotate the torque selector collar until the hammer symbol appears in line with the arrow. Apply pressure to the bit to engage the hammering mechanism.
   NOTE: When using carbide bits, do not use water to settle dust. Do not attempt to drill through steel reinforcing rods. This will damage the carbide bits.

2. To use the drilling-only mode, rotate the torque selector collar until the drill symbol appears in line with the arrow.

3. To use the driving screws mode, rotate the torque selector collar until the desired clutch setting appears in line with the arrow.
   The adjustable clutch, when properly adjusted, will slip at a preset torque to prevent driving the screw too deep into different materials and to prevent damage to the screw or tool.

The torque specifications shown here are approximate values obtained with a fully charged battery pack.

Starting, Stopping, and Controlling Speed

1. To start the tool, grasp the handle 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 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 bit comes to a complete stop before laying the tool down.

Battery Pack Protection
To protect the battery from damage and extend its life, the tool’s intelligent circuit monitors current draw, temperature, and voltage drops.
In extremely high torque, binding, stalling, and short circuit situations that cause high current draw, the fuel gauge will flash, and then the tool will turn OFF. To reset, release the trigger.
Under extreme circumstances, the internal tem-perature of the battery could become too high. If this happens, the fuel gauge will flash and the battery pack will shut off. Let the battery pack cool and then continue work.

APPLICATIONS

WARNING
To reduce the risk of electric shock, check work area for hidden pipes and wires before drilling or driving screws. Drilling in Wood, Composition Materials

When drilling in wood, composition materials and plastic, select the drill- only operating mode. Start the drill slowly, gradually increasing speed as you drill. When drilling into wood, use wood augers or twist drill bits. Always use sharp bits. When using twist drill bits, pull the bit out of the hole frequently to clear chips from the bit flutes. To reduce the chance of splintering, back work with a piece of scrap wood. Select low speeds for plastics with a low melting point.

Drilling in Metal
When drilling in metal, select the drill-only oper-ating 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 material to prevent binding and distortion on breakthrough.

Drilling in Masonry
When drilling in masonry, select the hammer drill 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. Both actions will damage the carbide.

Driving Screws and Nut Running
Drill a pilot hole when driving screws into thick or hard materials. Set the torque selector collar to the proper position and set the speed to low. Use the proper style and size screwdriver bit for the type of screw you are using. With the screwdriver bit in the screw, place the tip of the screw on the workpiece and apply firm pressure before pulling the trigger. Screws can be removed by reversing the motor.

Overloading
Continuous overloading may cause permanent damage to the tool or battery pack.

MAINTENANCE

WARNING To reduce the risk of injury, always sunplug the charger and remove the battery pack from the charger or tool before perform-ing any maintenance. Never disassemble the tool, battery pack or charger. Contact a MILWAUKEE service facility for ALL repairs.

Maintaining Tool
Keep your tool, battery pack and charger in good repair by adopting a regular maintenance program. Inspect your tool for issues such as undue noise, misalignment or binding of moving parts, breakage of parts, or any other condition that may affect the tool operation. Return the tool, battery pack, and charger to a MILWAUKEE service facility for repair. After six months to one year, depending on use, return the tool, battery pack and charger to a MILWAUKEE service facility for inspection.
If the tool does not start or operate at full power with a fully charged battery pack, clean the contacts on the battery pack. If the tool still does not work prop-erly, return the tool, charger and battery pack, to a MILWAUKEE service facility for repairs.

WARNING To reduce the risk of personal injury and damage, never immerse your tool, battery pack or charger in liquid or allow a liquid to flow inside them.

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

Repairs
For repairs, return the tool, battery pack and charger to the nearest authorized service center.
