GENERAL POWER TOOL

SAFETY WARNINGS

Read all safety warnings, instructions, 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 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 operating 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 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.

• Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

• 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 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 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 at 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 children 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, and tool bits 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 designated 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, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact acciden­ tally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
• Do not use a battery pack or tool that is dam­ aged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion, or risk of injury.
• Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or tem­perature above 265°F (130°C) may cause an explosion.
• Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging im­properly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

SERVICE

• Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
• • Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

SPECIFIC SAFETY RULES FOR ROTARY HAMMER

• Wear ear protectors. Exposure to noise can cause hearing loss.

• Use auxiliary handle(s), if supplied with the tool.
  L o s s of c o n t r o l c a n c u s e p e r s o n a l I n j u r y.

• Hold power tools by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

• Keep hands away from all cutting edges and moving parts.

• Chemical Burn Hazard. Keep coin cell batteries away from children. (Cat. No. 2914-20 only)

• To reduce the risk of injury, when working in dusty situations, wear appropriate respiratory protection or use an OSHA-compliant dust extraction solution.

• Always use common sense and be cautious when using tools. It is not possible to anticipate every situation that could result in a dangerous outcome.
  Do not use this tool if you do not understand these operating instructions or you feel the work is beyond your capability; contact Milwaukee Tool or a trained professional for additional information or training.

• Maintain labels and nameplates. These carry important information. If unreadable or missing, contact a MILWAUKEE service facility for a free replacement.

• Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contain chemicals known to cause cancer, birth defects, or other reproductive harm. Some examples of these chemicals are:

• lead from lead-based paint

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemically treated lumber.
  Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well-ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

S electing 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 the 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
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.

1. For forwarding (clockwise) rotation, push in the control switch from the right side of the tool. Check the direction of rotation before use.

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

3. 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 any time the tool is not in use.

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(s) 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. Ensure the tool has come 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.
The AUTOSTOP™ kickback control feature senses a bind and when the tool turns too much in a bind-up situation, the electronics shut the tool off.
There is an onboard light that will blink when AUTOSTOP™ activates.
NOTE: 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 Anti-Vibration System provides the operator with comfort without sacrificing power or performance.
Ideal operator force compresses the bellows slightly and allows the tool to work aggressively while the handle remains steady.
Excessive force compresses the bellows significantly and reduces vibration dampening. Users will be able to feel the difference and should adjust the force to the handle accordingly.

APPLICATIONS

To reduce the risk of electric shock, check the work area for hidden pipes and wires before drilling or driving screws.
Selecting Bits
When selecting a bit, use the right type for your job.
For best performance, always use sharp bits.
Drilling

1. Before drilling, be sure the workpiece is clamped securely. Use packing material to prevent damage to the workpiece during breakthrough.
2.  When starting a hole, place the drill bit on the work surface and apply firm pressure. Begin drilling at a slow speed, gradually increasing the speed as you drill.
3. Always apply pressure in line with the bit. Use enough pressure to keep the drill biting, but do not push hard enough to stall the motor.
4. Reduce pressure and ease the bit through the last part of the hole. While the tool is still running, pull the bit out of the hole to prevent jamming.

Drilling in Wood, Composition Materials, and Plastic
(Use chuck adapter kit Cat. No. 48-66-1370)
When drilling in wood, composition materials, and plastic, 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.

MAINTENANCE

To reduce the risk of injury, always unplug the charger and remove the battery pack from the charger or tool before performing 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.
