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.

1. Work area safety
   a. Keep the 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 that may ignite 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 the 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. The 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 Interrupter (GFCI) protected supply. The 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 inattention while operating power tools may result in serious personal injury.
   b. Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non-skid safety shoes, hard hats, 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 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.
   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 and clothing 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. The use of dust collection can reduce dust-related hazards.
   h. 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.

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 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.
   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 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.
   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.
   h. 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.

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 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.
   d. Under abusive conditions, liquid may be ejected from the battery, avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
   e. Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion, or risk of injury.
   f. Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265 °F may cause an explosion.
   g. 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.

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.
   b. Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Rules for Cordless Impact Wrenches

a. Hold the power tool by insulated gripping surfaces, when performing an operation where the fastener may contact hidden wiring. Fasteners contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
b. Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
c. Do not drive fasteners into existing walls or other blind areas where electrical wiring may exist. If this situation is unavoidable, disconnect all fuses or circuit breakers feeding this worksite.
d. Use only sockets designed for power impact wrenches. Sockets designed for hand use may break under the load this tool generates.
e. Be certain to seat the socket completely and securely on the output drive.
f. Do not use worn or damaged sockets.
g. Select the correct size sockets and keep the inside of the socket clean.
h. Do not allow a loose fastener to spin freely within the socket. The fastener may be thrown out of the socket.
i. Use thick cushioned gloves and limit the exposure time by taking frequent rest periods. Vibration caused by impact driver action may be harmful to your hands and arms.
j. Remove battery pack before changing accessories. Accidental starting may occur because battery appliances with a battery inserted are in the operative condition.
k. Be prepared for a reaction torque when “seating” or removing a fastener. The tool housing may tend to twist in the opposite direction of accessory rotation when “seating” or removing a fastener depending on the torque setting of the tool.
l. Do not run the tool while carrying it at your side. The rotating drive could become entangled with clothing and injury may result.
m. Place the tool onto the fastener only when the tool is switched off. Rotating driver tools can slide off the fastener.

Additional Safety Warnings

a. GFCI and personal protection devices like electrician’s rubber gloves and footwear will further enhance your personal safety.
b. Develop a periodic maintenance schedule for your tool. When cleaning a tool be careful not to disassemble any portion of the tool since internal wires may be misplaced or pinched or safety guard return springs may be improperly mounted. Certain cleaning agents such as gasoline, carbon tetrachloride, ammonia, etc. may damage plastic parts.
c. Ensure the switch is in the off position before inserting the battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.
****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 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.

Operating Instructions

Intended Use
CAUTION This tool is intended for the tightening and loosening of bolts, nuts, and various threaded fasteners. This tool is not intended for use as a drill.
Variable Speed Controlled Trigger Switch
Your tool is equipped with a variable speed trigger switch. The tool can be turned “ON” or “OFF” by squeezing or releasing the trigger. The speed can be adjusted from the
minimum to maximum nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).
Brake
When the trigger switch is released it activates the brake to stop the chuck quickly. This is especially useful in the repetitive driving and removal of screws.

Forward/Reversing Lever and Trigger Lock

WARNING After tool use, lock trigger in “OFF” position to help prevent accidental starts and accidental discharge.
CAUTION Do not change direction of rotation until the tool comes to a complete stop. Shifting during the rotation of the chuck can cause damage to the tool.
Your tool is equipped with a forward/ reversing lever and trigger lock (3) located above the trigger (Fig. 10). This lever was designed for changing the rotation of the socket, and for locking the trigger in an “OFF” position.
To lock the trigger, move the lever to the center.
For forward rotation, (with chuck pointed away from you) move the lever to the far left.
For reverse rotation move the lever to the far right. To activate the trigger lock move the lever to the center off position. 1

Built-in work light
Your tool is equipped with an LED light (13) for better visibility when using the tool. After the trigger (8) is activated, the LED will then stay on for 10 seconds. The length
of time for afterglow can be changed in ‘Bosch ToolBox’ app setting (if connected).
Operating tips
You will extend the life of your bits and do neater work if you always put the bit in contact with the work before pulling the trigger. During the operation, hold the tool firmly and exert light, steady pressure. Too much pressure at low speed will stall the tool. This can be damaging to both the tool and the bit.
Driving with variable speed
The technique is to start slowly, increasing the speed as the screw runs down. Set the screw snugly by slowing to a stop. Prior to driving screws, pilot and clearance holes should be drilled.

Always hold the tool straight on the bolt to be tightened. The best method to determine the right impacting/tightening duration is by means of a trial. For small screws, the right
impacting/ tightening duration can be reached in less than 0.5 Sec. Therefore, work with low RPM and switch the tool off immediately when the screw is tight and the impacting sound can be heard. For screwing larger, longer wood screws into hard material, pre-drilling is the best method.

Tightening Torque
The tightening torque depends on the duration of the impacting/tightening action. The largest tightening torque is achieved after approx. 6 to 10 Sec. impacting / tightening action. The torque build-up depends on the following factors:

• Hardness of the bolts/nuts.
• Type of washer (disk washer, spring washer, seal).
• Hardness of the material to be joined.
• Lubricating effect at the surfaces of the junction.

This leads to the following application cases:
Hard joining application: The joining of metal to metal with a disk washer. The maximum torque is reached after a relatively short impacting/tightening action. Medium joining application: The joining of metal to metal when using a spring ring washer, disk spring washer, stud bolts or bolts/nuts with conical seats. Soft joining application: The joining of e.g. metal to wood or insulation material. For middle or soft joining cases, the maximum tightening torque is less than for hard cases. Therefore, a longer impacting/tightening action is necessary to arrive at the maximum tightening torque.

Selecting the working mode
The power tool has two preset working modes: A and B (17). You can also program working modes for different applications and adjust existing modes via the Bosch Toolbox under A and B. To switch between the working modes A and B (17), press the Mode button (16).
Default Mode A is designed for SelfDrilling Screws. Auto Slow Down is activated in both the forward and reverse directions. By Default Mode B is designed for Wood Screws. In the forward direction, Auto Shutoff is activated. In the reverse direction, Auto Shut Off functions as Auto-Bolt Release for the default Mode B. Note: Only one Setting or Mode can be active on the tool at a time. 1, 2, 3, A, or B.

Fastening with screws
The procedure shown in (Fig. 11) will help to fasten materials together with your tool and will reduce the possibility of stripping, splitting or separating the material.

First, clamp the pieces together and drill the first hole 2/3 the diameter of the screw. If the material is soft, drill only 2/3 the proper length. If it is hard, drill the entire length.
Second, unclamp the pieces and drill the second hole the same diameter as the screw shank in the first or top piece of wood.
Third, if the flat head screw is used, countersink the hole to make the screw flush with the surface. Then, simply apply even pressure when driving the screw. The screw shank clearance hole in the first piece allows the screw head to pull the pieces tightly together.

Driving nuts and bolts
Use variable speed control with caution for driving nuts and bolts with socket attachments. The technique is to start slowly, increasing speed as the nut or bolt runs down. The nut or bolt is set when the socked comes to a stop.
Note: Ensure that no metal particles enter the power tool. After working at a low speed for an extended period, you should operate the power tool at the maximum speed for approximately three minutes without load to cool it down.
Cold weather use (32°F)
Due to the lubrication used in the impacting mechanism, the tool should be run for three minutes at no load prior to actual usage. This will warm the lubricant and provide better performance.

User interface
Status indicator LED
The LED bar at the top of the user interface illuminates in various colors to help the user identify the status of the tool. When the status indicator LED (12) is green, the tool and battery pack are operating normally and temperatures are ok. If the indicator changes to yellow, it means that the tool or battery temperatures have risen to a high level, and the use of the tool must stop to allow the tool to cool off. It is best to back off the load and give the tool chance to cool down. If the indicator turns red, the tool will shut off to protect itself and/or the battery pack from an overheating situation. The status indicator LED (12) will also blink blue when the speed (14) or mode (16) buttons are held for 7 seconds. This will reset the tool settings to factory default.

Joist Hanger

WARNING When using the joist hanger always be aware that the accessory is exposed. Always hang the tool in an area where you and bystanders cannot accidently make contact with the accessory.
WARNING To reduce the risk of injury, Do not use the joist hanger if it appears damaged or deformed. This could result in unstable hanging and the tool unexpectedly falling. To reduce the risk of injury, use care in selecting the location for hanging the tool.
The optional joist hanger accessory (4) will allow you to conveniently attach your tool to a joist, or other convenient support when not in use.
The joist hanger (4) can be attached to either side of the tool by securing it with a mounting screw. Always make sure you securely tighten the mounting screw before
use (Fig.1).

• Select a suitably sized and shaped object that will provide adequate hanging stability. An unstable hanging surface could result in the tool unexpectedly falling.
• Ensure that the tool is hung out of the way of walkways and working areas with bystanders. The tool could be bumped or a bystander could become entangled causing the tool to unexpectedly fall.

Maintenance

WARNING To avoid accidents, always disconnect the battery pack from the tool before servicing or cleaning.

Service

WARNING NO USER SERVICEABLE PARTS INSIDE. Preven – tive maintenance performed by un au theorized personnel may result in misplacing of internal wires and components which could cause serious hazards. We recommend that all tool services be performed by a Bosch Factory Service Center or Authorized Bosch Service Station.

Batteries
Be alert for battery packs that are nearing their end of life. If you notice decreased tool performance or significantly shorter running time between charges then it is time to replace the battery pack. Failure to do so can cause the tool to operate improperly or damage the charger.
Tool Lubrication
Your Bosch tool has been properly lubricated and is ready for use.
Motors
The motor in your tool has been engineered for many hours of dependable service. To maintain peak efficiency of the motor, we recommend it be examined every six months. Only a genuine Bosch replacement motor specially designed for your tool should be used.

Cleaning
CAUTION Certain cleaning agents and solvents damage plastic parts. Some of these are gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia, and household detergents that contain ammonia. Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by inserting pointed objects through the opening.

Accessories

WARNING The use of any other attachments or access that is not specified in this manual may create a hazard. Store accessories in a dry and temperate environment to avoid corrosion and deterioration.
