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 Driver

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. Remove battery pack before changing accessories. Accidental starting may occur because battery appliances with a battery inserted are in the operative condition.
e. Do not run the tool while carrying it at your side. The rotating drive could become entangled with clothing and injury may result.
f. Place the tool onto the fastener only when the tool is switched off. Rotating driver tools can slide off the fastener.
g. Ensure trigger lock is engaged before inserting battery pack. Inserting the battery pack into power tools that have the switch on invites accidents.

Additional Safety Warnings

GFCI and personal protection devices like electrician's rubber gloves and footwear will further enhance your personal safety.

Do not use AC only rated tools with a DC power supply. While the tool may appear to work, the electrical components of the AC rated tool are likely to fail and create a hazard to the operator.

Keep handles dry, clean and free from oil and grease. Slippery hands cannot safely control the power tool.

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.

Operating Instructions

Variable Speed Controlled Trigger Switch

(Fig. 1)

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.

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 rotation of the chuck can cause damage to the tool.

(Fig. 10)

Your tool is equipped with a Forward/Reversing Lever and Trigger Lock 3 located above the trigger. This lever was designed for changing 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 trigger lock move lever to the center off position.

Fig. 10

Built-In Work Light

Your tool is equipped with an LED light 10, 15 for better visibility when using the tool.

After the trigger 9 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 tool and 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/

Operating Instructions

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 relative short impacting/tightening action.

Medium joining application: The joining of metal to metal when using 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.

Fastening with Screws

(Fig. 11)

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.

FASTENING WITH SCREWS 1. Drill 2/3 diameter and 2/3 of screw length for soft materials, full length for hard materials. 2. Drill same diameter as screw shank. 3. Countersink same diameter as screw head. Apply a slight even pressure when driving screws. Screw Fig. 11

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 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.

Operating Instructions

User Interface

(Fig. 12)

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 16 or Mode 14 buttons are held for 7 seconds. This will reset the tool settings to factory default.

The Bosch Toolbox app offers an option to allow the user interface to be locked and unlocked on the tool. When the “(Un-)Lock from tool” function in the Bosch Toolbox app is selected, holding the Speed 16 and Mode 14 buttons for 5 seconds will lock or unlock the user interface.

Note: If the "Lock User Interface" function is activated, the reset to factory settings option on the power tool is deactivated.

Selecting the Speed

The power tool has three preset speed levels. Press the Speed Preselection Button 16 to select the desired speed. The selected speed will be displayed on the Preselection Level Indicator 17. For speed and impact ratings for each preset level, see section "Functional Description and Specifications".

Selecting the Working Mode

The power tool has two preset working modes: A and B. You can adjust settings within the existing A and B modes or program custom working modes for specific applications via the Bosch Toolbox app.

(Fig. 12) (12) 1 2 3 A B SPEED MODE (13)(14)(16)(17)

Press the Mode button 14 to switch between working modes A and B. The selected mode will be displayed on the Mode Selection Indicator 13.

• Default mode A has two features that are designed for metal bolts: Shut-off After Time in the forward direction and Auto-Bolt Release in the reverse direction. Shut-off After Time will stop the power tool after 1 second of fastening. Auto-Bolt Release will stop the power tool once a sudden decrease in resistance is detected while loosening.
• Default mode B is designed for wood screws: the feature Auto Shutoff is activated in the forward direction. Auto Shutoff will stop the power tool once added resistance is detected while fastening.

Note: only one speed setting or mode can be active on the tool at a time: 1, 2, 3, A, or B. The Bosch Toolbox app can be used to combine specific working mode features and speeds.

Operating Instructions

Belt Clip

WARNING

When using the belt clip always be aware that the

accessory is exposed. Always hang the tool in an area where yourself and bystanders cannot accidentally make contact with the accessory.

WARNING

To reduce the risk of in-jury, do not use the belt

clip if it appears damaged or deformed. This could result in unstable hanging and the tool unexpectedly falling.

WARNING

To reduce the risk of in-jury, use care in selecting

the location for hanging the tool.

(Fig. 1)

The optional belt clip accessory will allow you to conveniently attach your tool to your belt. This feature will allow you to have both hands free when climbing a ladder or moving to another work area.

The Belt Clip 5 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).

To use clip, turn tool upside down and attach to your belt.

Maintenance

WARNING

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

Service

WARNING

NO USER SERVICEABLE PARTS INSIDE. Preventive maintenance performed by unauthorized personnel may result in misplacing of internal wires and components which could cause serious hazard. We recommend that all tool service 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, car bon 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 opening.

Accessories

WARNING

The use of any other attachments or accessories not specified in this manual may create a hazard.

WARNING

Store accessories in a dry and temperate environment to avoid corrosion and deterioration.

This product is compatible with CR2032 batteries with a nominal battery voltage of 3V. (translation needed)
