WARNING:  To reduce the risk of injury, read the instruction  manual.  General Power Tool Safety Warnings WARNING! Read all safety warnings and all instructions.  Failure to follow the warnings and instructions 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.  # 1) WORK AREA SAFETY  a)  Keep work area clean and well lit.  Cluttered or dark areas  invite accidents. b)  Do not operate power tools in explosive atmospheres,  such as in the presence of flammable liquids, gases or  dust.  Power tools create sparks which may ignite the dust  or fumes. c)  Keep children and bystanders away while operating a  power tool.  Distractions can cause you to lose control. 2) ELECTRICAL SAFETY a)  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 risk of electric shock. b)  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. c)  Do not expose power tools to rain or wet conditions.  Water entering a power tool will increase the risk of electric  shock. d)  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.  e)  When operating a power tool outdoors, use an  extension cord suitable for outdoor use.  Use of a cord  suitable for outdoor use reduces the risk of electric shock.  f)  If operating a power tool in a damp location is  unavoidable, use a ground fault circuit interrupt er  (GFCI) protected supply.  Use of a GFCI reduces the risk of  electric shock. 3) PERSONAL SAFETY  a)  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 in attention  while operating power tools may result in serious personal  injury. b)  Use personal protective equipment. Always wear eye  protection.  Protective equipment such as dust mask, nonskid safety shoes, hard hat, or hearing protection used for  appropriate conditions will reduce personal injuries. c)  Prevent unintentional starting. Ensure the switch  is in the off position before connecting to 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. d)  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. e)  Do not overreach. Keep proper footing and balance at  all times.  This enables better control of the power tool in  unexpected situations. f)  Dress properly. Do not wear loose clothing or jewelry.  Keep your hair, clothing and gloves away from moving  parts.  Loose clothes, jewelry or long hair can be caught in  moving parts.  g)  If devices are provided for the connection of dust  extraction and collection facilities, ensure these are  connected and properly used.  Use of dust collection can  reduce dust-related hazards. 4) POWER TOOL USE AND CARE a)  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. b)  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.  c)  Disconnect the plug from the power source and/or the  battery pack 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. d)  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. e)  Maintain power tools. 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. f)  Keep cutting tools sharp and clean.  Properly maintained  cutting tools with sharp cutting edges are less likely to bind  and are easier to control.  $g)$    Use the power tool, accessories and 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. 5) BATTERY TOOL USE AND CARE a)  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. b)  Use power tools only with specifically designated  battery packs.  Use of any other battery packs may create a  risk of injury and fire. c)  When 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.  
d)  Under abusive conditions, liquid may be ejected from  the battery; avoid contact. If contact accidentally  occurs, flush with water. If liquid contacts eyes,  additionally seek medical help.  Liquid ejected from the  battery may cause irritation or burns. 6) SERVICE a)  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. Drill/Driver/Hammer drill Safety  Warnings • Wear ear protectors when impact drilling.  Exposure to  noise can cause hearing loss. • Use auxiliary handle(s), if supplied with the tool.  Loss of  control can cause personal injury. •  Hold power tool 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. • Use clamps or other practical way to secure and support  the workpiece to a stable platform.  Holding the work by  hand or against your body is unstable and may lead to loss of  control. • Wear safety goggles or other eye protection.  Hammering  and drilling operations cause chips to fly. Flying particles can  cause permanent eye damage. •   Accessories and tool may get hot during operation.   Wear gloves when handling them if performing heat producing  applications such as hammer drilling and drilling metals. • Do not operate this tool for long periods of time.  Vibration  caused by hammer action may be harmful to your hands and  arms. Use gloves to provide extra cushion and limit exposure by  taking frequent rest periods.  •  Air vents often cover moving parts and should be  avoided.  Loose clothes, jewelry or long hair can be caught in  moving parts.  WARNING:  ALWAYS  use  safety  glasses.  Everyday  eyeglasses are NOT safety glasses. Also use face or dust mask  if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY  EQUIPMENT: • ANSI Z87.1 eye protection (CAN/CSA Z94.3), • ANSI S12.6 (S3.19) hearing protection, • NIOSH/OSHA/MSHA respiratory protection.  WARNING:  Some dust created by power sanding, sawing,  grinding, drilling, and other construction activities contains  chemicals known to the State of California to cause cancer, birth  defects or other reproductive harm. Some examples of these  chemicals are: • lead from lead-based paints, •  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. •  Avoid prolonged contact with dust from power sanding,  sawing, grinding, drilling, and other construction  activities. Wear protective clothing and wash exposed  areas with soap and water.  Allowing dust to get into your  mouth, eyes, or lay on the skin may promote absorption of  harmful chemicals.   WARNING:  Use of this tool can generate and/or disperse dust,  which may cause serious and permanent respiratory or other  injury. Always use NIOSH/OSHA approved respiratory protection  appropriate for the dust exposure. Direct particles away from face  and body.  WARNING: Always wear proper personal hearing  protection that conforms to ANSI S12.6 (S3.19) during  use.  Under some conditions and duration of use, noise from this  product may contribute to hearing loss.  CAUTION: When not in use, place tool on its side on a  stable surface where it will not cause a tripping or falling  hazard.  Some tools with large battery packs will stand upright on  the battery pack but may be easily knocked over.  • The label on your tool may include the following symbols. The  symbols and their definitions are as follows:   # Important Safety Instructions for All  Battery Packs  When ordering replacement battery packs, be sure to include the  catalog number and voltage. Consult the chart at the end of this  manual for compatibility of chargers and battery packs.  The battery pack is not fully charged out of the carton. Before  using the battery pack and charger, read the safety instructions  below and then follow charging procedures outlined.  # READ ALL INSTRUCTIONS  •  Do not charge or use the battery pack in explosive  atmospheres, such as in the presence of flammable  liquids, gases or dust.  Inserting or removing the battery pack  from the charger may ignite the dust or fumes. • NEVER force the battery pack into the charger. DO NOT  modify the battery pack in any way to fit into a noncompatible charger as battery pack may rupture causing  serious personal injury.  Consult the chart at the end of this  manual for compatibility of batteries and chargers.  • Charge the battery packs only in designated Maker chargers. •  DO NOT  splash or immerse in water or other liquids. • Do not store or use the tool and battery pack in locations  where the temperature may reach or exceed 105 °F (40 °C)  (such as outside sheds or metal buildings in summer).  For  best life store battery packs in a cool, dry location.    NOTE: Do not store the battery packs in a tool with the  trigger switch locked on. Never tape the trigger switch in  the ON position.  WARNING:  Fire hazard. Never attempt to open the battery pack  for any reason. If the battery pack case is cracked or damaged,  do not insert into the charger. Do not crush, drop or damage  the battery pack. Do not use a battery pack or charger that has  received a sharp blow, been dropped, run over or damaged in  any way (e.g., pierced with a nail, hit with a hammer, stepped on).  Damaged battery packs should be returned to the service center  for recycling.  WARNING: Fire hazard. Do not store or carry the battery  pack so that metal objects can contact exposed battery  terminals.  For example, do not place the battery pack in aprons,  pockets, tool boxes, product kit boxes, drawers, etc., with loose  nails, screws, keys, etc.  Transporting batteries can possibly  cause fires if the battery terminals inadvertently come in  contact with conductive materials such as keys, coins,  hand tools and the like.  The US Department of Transportation  Hazardous Material Regulations (HMR) actually prohibit transporting  batteries in commerce or on airplanes (e.g., packed in suitcases  and carry-on luggage) UNLESS they are properly protected from  short circuits. So when transporting individual battery packs, make  sure that the battery terminals are protected and well insulated  from materials that could contact them and cause a short circuit.  
# SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION  (Li-Ion)  •  Do not incinerate the battery pack even if it is severely  damaged or is completely worn out.  The battery pack can  explode in a fire. Toxic fumes and materials are created when  lithium ion battery packs are burned. •  If battery contents come into contact with the skin,  immediately wash area with mild soap and water.   $I\!f$  battery liquid gets into the eye, rinse water over the open eye  for 15 minutes or until irritation ceases. If medical attention is  needed, the battery electrolyte is composed of a mixture of  liquid organic carbonates and lithium salts. •  Contents of opened battery cells may cause respiratory  irritation.  Provide fresh air. If symptoms persist, seek medical  attention. WARNING:  Burn hazard. Battery liquid may be flammable   $i f$    exposed to spark or flame.  # Important Safety Instructions for All  Battery Chargers  SAVE THESE INSTRUCTIONS:  This manual contains important  safety and operating instructions for battery chargers. • Before using the charger, read all instructions and cautionary  markings on the charger, battery pack and product using the  battery pack. WARNING:  Shock hazard. Do not allow any liquid to get inside  the charger. Electric shock may result. CAUTION:  Burn hazard. To reduce the risk of injury, charge  only professional rechargeable battery packs. Other types of batteries  may overheat and burst resulting in personal injury and property  damage. NOTICE:  Under certain conditions, with the charger plugged into  the power supply, the charger can be shorted by foreign material.  Foreign materials of a conductive nature, such as, but not limited to,  grinding dust, metal chips, steel wool, aluminum foil or any buildup  of metallic particles should be kept away from the charger cavities.  Always unplug the charger from the power supply when there is no  battery pack in the cavity. Unplug the charger before attempting to  clean. •  DO NOT attempt to charge the battery pack with any  chargers other than the ones in this manual.  The charger  and battery pack are specifically designed to work together.  •  These chargers are not intended for any uses other than  charging professional rechargeable batteries.  Any other uses  may result in risk of fire, electric shock or electrocution. •  Do not expose the charger to rain or snow. •  Pull by the plug rather than the cord when disconnecting  the charger.  This will reduce the risk of damage to the electric  plug and cord. •  Make sure that the cord is located so that it will not  be stepped on, tripped over or otherwise subjected to  damage or stress. •  Do not use an extension cord unless it is absolutely  necessary.  Use of improper extension cord could result in risk  of fire, electric shock or electrocution. •  When operating a charger outdoors, always provide a dry  location and use an extension cord suitable for outdoor  use.  Use of a cord suitable for outdoor use reduces the risk of  electric shock.  •  An extension cord must have adequate wire size (AWG  or American Wire Gauge) for safety.  The smaller the gauge  number of the wire, the greater the capacity of the cable, that is,  16 gauge has more capacity than 18 gauge. An undersized cord  will cause a drop in line voltage resulting in loss of power and  overheating. When using more than one extension to make up the  total length, be sure each individual extension contains at least the  minimum wire size. The following table shows the correct size to  use depending on cord length and nameplate ampere rating. If in  doubt, use the next heavier gauge. The lower the gauge number,  the heavier the cord.   •  Do not place any object on top of the charger or place the  charger on a soft surface that might block the ventilation  slots and result in excessive internal heat.  Place the  charger in a position away from any heat source. The charger  is ventilated through slots in the top and the bottom of the  housing. •  Do not operate the charger with a damaged cord or plug. •  Do not operate the charger if it has received a sharp  blow, been dropped or otherwise damaged in any way.   Take it to an authorized service center. •  Do not disassemble the charger; take it to an authorized  service center when service or repair is required.  Incorrect  reassembly may result in a risk of electric shock, electrocution or  fire. •  Disconnect the charger from the outlet before attempting  any cleaning. This will reduce the risk of electric shock.   Removing the battery pack will not reduce this risk. •  NEVER  attempt to connect 2 chargers together. •  The charger is designed to operate on standard 120V  household electrical power. Do not attempt to use it  on any other voltage.  This does not apply to the vehicular  charger.

# Charge Indicators  This charger is designed to detect certain problems that can arise.  Problems are indicated by the red light flashing at a fast rate. If this  occurs, re-insert the battery pack into the charger. If the problem  persists, try a different battery pack to determine if the charger is  working properly. If the new pack charges correctly, then the original  pack is defective and should be returned to a service center or other  collection site for recycling. If the new battery pack elicits the same  trouble indication as the original, have the charger and the battery  pack tested at an authorized service center.  # HOT/COLD DELAY  # DCB101  This charger has a hot/cold delay feature: when the charger detects  a battery that is hot, it automatically starts a delay, suspending  charging until the battery has cooled. After the battery has cooled,  the charger automatically switches to the pack charging mode. This  feature ensures maximum battery life. The red light flashes long,  then short while in the hot/cold delay mode.  # DCB107, DCB112  The DCB107 and DCB112 chargers have a hot/cold delay feature.  When the charger detects a battery that is hot, it automatically  delays charging until the battery has cooled. When the charger  detects a battery that is cold, it automatically delays charging until  the battery has warmed.  The red light will continue to blink, but a yellow indicator light will  be illuminated during this operation. Once the battery has cooled,  the yellow light will turn off and the charger will resume the charging  procedure.  # LEAVING THE BATTERY PACK IN THE CHARGER  The charger and battery pack can be left connected with the  charge indicator showing Pack Charged.  WEAK BATTERY PACKS:  Weak batteries will continue to function  but should not be expected to perform as much work.  FAULTY BATTERY PACKS:  This charger will not charge a faulty  battery pack. The charger will indicate faulty battery pack by refusing  to light or by displaying problem pack or charger.  NOTE:  This could also mean a problem with a charger.  # PROBLEM POWER LINE (DCB101)  Some chargers have a Problem Power Line indicator. When the  charger is used with some portable power sources such as  generators or sources that convert DC to AC, the charger may  temporarily suspend operation, flashing the red light with two fast  blinks followed by a pause. This indicates the power source is out  of limits.  # Wall Mounting  These chargers are designed to be wall mountable or to sit upright  on a table or work surface. If wall mounting, locate the charger within reach of an electrical  outlet. Mount the charger securely using drywall screws at least   $1"$   $^{\bullet}\,(25.4\;\mathsf{m m})$  ) long, screwed into wood to an optimal depth leaving  approximately  $7/\bar{3}2"$     $(5.5\;\mathsf{m m})$  ) of the screw exposed.  # Important Charging Notes  1. Longest life and best performance can be obtained if the  battery pack is charged when the air temperature is between   $65~^{\circ}\mathrm{F}$   and 75 °F   $(18^{\circ}\mathrm{-}24~^{\circ}\mathrm{C})$  . DO NOT charge the battery pack  in an air temperature below   $\dot{}_{+40}$   °F   $(+4.5~^{\circ}\mathrm{C})$  , or above   $+\dot{\,}1\dot{\,}05$   °F   $(+40.5~^{\circ}\mathrm{C})$  ). This is important and will prevent serious damage  to the battery pack.  2. The charger and battery pack may become warm to the  touch while charging. This is a normal condition, and does not  indicate a problem. To facilitate the cooling of the battery pack  after use, avoid placing the charger or battery pack in a warm  environment such as in a metal shed or an un insulated trailer.  3. A cold battery pack will charge at about half the rate of a warm  battery pack. The battery pack will charge at that slower rate  throughout the entire charging cycle and will not return to  maximum charge rate even if the battery pack warms.  4. If the battery pack does not charge properly:    a.  Check operation of receptacle by plugging in a lamp or other  appliance;    b.  Check to see if receptacle is connected to a light switch  which turns power off when you turn out the lights;     c.  Move the charger and battery pack to a location where the  surrounding air temperature is approximately 6  $\mathsf{i}5\ {}^{\circ}\mathsf{F}{-}75\ {}^{\circ}\mathsf{F}$     $(18^{\circ}–24~^{\circ}\bar{\mathrm{C}})$  ;     d.  If charging problems persist, take the tool, battery pack and  charger to your local service center.  5. The battery pack should be recharged when it fails to produce  sufficient power on jobs which were easily done previously.  DO NOT CONTINUE to use under these conditions. Follow  the charging procedure. You may also charge a partially used  pack whenever you desire with no adverse effect on the battery  pack.  6. Foreign materials of a conductive nature such as, but not  limited to, grinding dust, metal chips, steel wool, aluminum foil,  or any buildup of metallic particles should be kept away from  charger cavities. Always unplug the charger from the power  supply when there is no battery pack in the cavity. Unplug the  charger before attempting to clean.  7. Do not freeze or immerse the charger in water or any other  liquid. WARNING:  Shock hazard. Don’t allow any liquid to get inside  the charger. Electric shock may result.  
WARNING:  Burn hazard. Do not submerge the battery pack  in any liquid or allow any liquid to enter the battery pack. Never  attempt to open the battery pack for any reason. If the plastic  housing of the battery pack breaks or cracks, return to a service  center for recycling.  # Storage Recommendations  1. The best storage place is one that is cool and dry, away from  direct sunlight and excess heat or cold.  2. For long storage, it is recommended to store a fully charged  battery pack in a cool dry place out of the charger for optimal  results. NOTE:  Battery packs should not be stored completely depleted  of charge. The battery pack will need to be recharged before use.  # SAVE THESE INSTRUCTIONS FOR  FUTURE USE  # COMPONENTS (Fig. 2)

 2. Use sharp drill bits only. For MASONRY, such as brick, cement,  cinder block, etc., use carbide-tipped bits rated for percussion  drilling.  
3. Always apply pressure in a straight line with the bit. Use  enough pressure to keep drill  biting, but do not push hard  enough to stall the motor or  deflect the bit.  4. Hold tool firmly with both hands  to control the twisting action of  the drill. If model is not equipped  with side handle, grip drill with  one hand on the handle and  one hand on the battery pack.  WARNING:  Drill may stall if overloaded causing a sudden twist.  Always expect the stall. Grip the drill firmly to control the twisting  action and avoid injury.  5.  IF DRILL STALLS , it is usually because it is being overloaded  or improperly used.  RELEASE TRIGGER IMMEDIATELY ,  remove drill bit from work, and determine cause of stalling.  DO  NOT DEPRESS TRIGGER ON AND OFF IN AN ATTEMPT  TO START A STALLED DRILL — THIS CAN DAMAGE THE  DRILL.  6. To minimize stalling or breaking through the material, reduce  pressure on drill and ease the bit through the last fractional part  of the hole.   7 . Keep the motor running when pulling the bit back out of a  drilled hole. This will help prevent jamming.  # Screw driving (Fig. 8)  
1. Select the desired speed/torque range using the gear shifter to  match the speed and torque to  the planned operation.  2. Turn the torque adjustment  collar (C) to the desired position.    NOTE:  Use the lowest torque  setting required to seat the  fastener at the desired depth. The lower the number, the lower  the torque output.  
3. Insert the desired fastener accessory into the chuck as you  would any drill bit.  4. Make some practice runs in scrap or on unseen areas of  the workpiece to determine the proper position of the torque  adjustment collar.   5. Always start with lower torque settings, then advance to higher  torque settings to avoid damage to the workpiece or fastener.  # Hammer drilling (Fig. 9)  1. Select the desired speed/torque range using the gear shifter to  match the speed and torque to  the planned operation. Turn the  collar (C) to the hammer drill  symbol.  
IMPORTANT:   Use  carbide- tipped or masonry bits rated for  percussion drilling only.  2. Drill with just enough force on  the hammer to keep it from  bouncing excessively or "rising" off the bit. Too much force will  cause slower drilling speeds, overheating, and a lower drilling  rate.  3. Drill straight, keeping the bit at a right angle to the work. Do not  exert side pressure on the bit when drillling as this will cause  clogging of the bit flutes and a slower drilling speed.  4. When drilling deep holes, if the hammer speed starts to drop  off, pull the bit partially out of the hole with tool still running to  help clear debris from the hole. NOTE:  A smooth, even flow of dust from the hole indicates proper  drilling rate.
