The machine is intended for hammer drilling inconcrete, brick and stone. It is also suitable fordrilling without impact in wood, metal, ceramicand plastic. Machines with electronic control andright/left rotation are also suitable for screw-driving and thread cutting.
Working safely with this ma-chine is possible only when theoperating and safety informationare read completely and the in-structions contained therein arestrictly followed. In addition, thegeneral safety notes in the en-
closed booklet must be ob-served. Before using for the firsttime, ask for a practical demon-stration.
Wear protective glasses and hearing protec-tion.
For long hair, wear hair protection. Work onlywith closely fitting clothes.
Before each use, check the machine and bat-tery. If damage is detected, do not use the ma-chine. Have repairs performed only by a qual-ified technician. Never open the machine your-self.
Use power tools only with specifically des-ignated battery packs. Use of any other bat-tery packs may create a risk of injury and fire.
Under abusive conditions, liquid may beejected from the battery; avoid contact. Ifcontact accidentally occurs, flush with wa-ter. If liquid contacts eyes, additionallyseek medical help. Liquid ejected from thebattery may cause irritation or burns.
Before any work on the machine itself (e. g.maintenance, tool change, etc.) as well aswhen transporting and storing, always setthe rotational direction switch to the centreposition. Otherwise danger of injury is givenwhen unintentionally actuating the On/Offswitch.
Ensure the switch is in the off position be-fore inserting battery pack. Inserting the bat-tery pack into power tools that have the switchon invites accidents.
Convince yourself before using that the battery
is securely seated in the machine. Do not strain the machine so heavily that it
comes to a standstill.
When working with the machine, always hold itfirmly with both hands and provide for a securestance.
Use the machine only with the auxiliary han-dle 11.
Hold the power tool only by the insulatedgripping surfaces, when performing an op-eration where the cutting tool may run intohidden wiring.Contact with a “live” wire will make exposedmetal parts of the tool “live” and shock the op-erator.
Use appropriate detectors to determine ifutility lines are hidden in the work area or
call the local utility company for assist-ance.Contact with electric lines can lead to fire andelectric shock. Damaging a gas line can leadto explosion. Penetrating a water line causesproperty damage.
Be careful when screwing in long screws; dan-ger of sliding off.
Set the machine against the screw/nut onlywhen switched off.
When screwdriving, operate in first gear aswell as with a low speed.
Always switch the machine off and wait until ithas come to a standstill before placing it down.
Never allow children to use the machine.
Bosch is only able to ensure perfect operationof the machine if the original accessories in-tended for it are used.
Battery and Battery Charger
The enclosed operating instructions for thebattery charger must be read carefully!
Recharge only with the charger specifiedby the manufacturer. A charger that is suita-ble for one type of battery pack may create arisk of fire when used with another batterypack.
Allow a heated battery to cool before charging.
Protect the battery from heat and fire: Dangerof explosion! Do not place the battery on radi-ators or expose to strong sun rays for a longertime; temperatures over 50 °C cause damage.
Do not open the battery, and protect it from im-
pact. Store in a dry and frost-free place. When battery pack is not in use, keep it
away from other metal objects like paperclips, coins, keys, nails, screws, or othersmall metal objects that can make a con-nection from one terminal to another.Shorting the battery terminals together maycause burns or a fire.
Do not dispose of the battery in householdwaste or discard into fire or water.

A battery that is new or has not been used for alonger period does not develop its full capacityuntil after approximately 5 charging/dischargingcycles.
To remove the battery 10, push back the releasebutton 13 and pull the battery out downwards. Donot exert any force (see figure ).
Please refer to the enclosed “Battery Charger” in-structions for the operation of the battery chargeras well as for a description of the charging proc-ess.
The battery is equipped with an NTC temperaturecontrol which allows charging only within a tem-perature range of between 0 °C and 45 °C.A long battery service life is achieved in this man-ner.
A significantly reduced working period after
charging indicates that the batteries are used andmust be replaced.
Observe the notes on environmental protec-tion.
Battery Charge Display
The battery 10 is fitted with a battery charge dis-play 9. It indicates the charge of the battery atany given time during the working process.
By pressing the button 8, the battery charge canalso be checked when the battery has been re-
moved, or when the machine is at a standstill. Af-ter approx. 4 seconds the battery charge displayautomatically turns off.
Battery charge:
When the first display element begins to flash(0 – 10%) the battery is almost empty and mustbe recharged.
To maintain the accuracy of the display, occa-sionally discharge the battery until the speed ofthe machine is considerably reduced and the bat-tery charge display has completely turned off.Frequent recharging after short intervals of useimpairs the accuracy of the display.
Use the machine only with the auxiliaryhandle 11.
Loosen the handle by turning to the left. Rotatethe auxiliary handle 11 and adapt to the workingposition. Make sure that the clamping band 17 ofthe auxiliary handle remains in the groove.
Firmly retighten the handle.
The drilling depth can be set with the depthstop 12.
For this, press the push-button for the depth-stopadjustment 4, adjust the required drilling depth Xand release the push-button for the depth-stopadjustment 4 again.
The ribbing on depth stop 12 must point upwards.
Before any work on the machine itself, re-move the battery.
With the SDS-plus tool holder, simpler and easiertool changing is possible without additional aids.
Grease the shank end of the tool regu-larly.
The dust protection cap 1 largely prevents theentry of drilling dust during operation. When in-serting the tool, take care that the dust protectioncap 1 is not damaged.
A damaged dust protection cap should bechanged immediately. We recommend havingthis carried out by an after-sales service.
As a requirement of the system, theSDS-plus tool must rotate freely. At no-loadspeed, this leads to a certain amount of ra-dial run-out.This does not affect the accuracy of the drillhole, as the bit is automatically centred dur-ing drilling.
Inserting (see figure )
Clean and grease the shank end of the tool.
Insert the tool in a twisting manner into the toolholder until it locks. Check if it has locked by pull-ing the tool.
Removing (see figure )
Push back the locking sleeve 2 of the tool holderand remove the tool.

Before re-inserting the battery 10 remove theprotective cap 14 if necessary (see figure ).
Set the rotational direction switch 6 to the centreposition (locked off). Slide the charged battery 10into the handle until it can be felt to latch.
Switching On and OffTo start the machine, press the On/Off switch 7and keep it depressed.
The machine runs with variablespeed between 0 and maximum,depending on the pressure appliedto the On/Off switch 7. Light pres-sure on the On/Off switch 7 resultsin low rotational speed, thus allow-ing drilling to begin in a smooth,controlled manner. Further pres-
sure on the switch results in an in-crease in speed.
To switch off the machine, release the On/Offswitch 7.
Do not strain the machine so heavily that it comesto a standstill.
The machine is not suitable for stationary op-eration, e. g., in a drill stand.
Overload Clutch
If the drill bit jams or edges, the drive to the
drill spindle is interrupted.Due to the arising forces always hold the ma-chine firmly with both hands and provide fora secure stance.
Before pulling out a stuck tool insert, first removethe machine from it.
Reversing the Rotational Direction
Operate the rotational direction switch 6only at a standstill.
The rotational direction switch 6 is used to re-verse the rotational direction of the machine.However, this is not possible with the On/Offswitch 7 actuated.
Right Rotation
Turn the rotational direc-tion switch through tothe left stop (normal op-eration: drilling, screw-driving, etc.).
Left Rotation
Press the rotational di-rection switch through tothe right stop (for loos-ening and unscrewingscrews and nuts).
Set the impact stop switch 5 to “Drilling”(only at a standstill).
Set the impact stop switch 5 to the desired posi-tion:
Drilling
Hammer drilling
When releasing the On/Off switch 7 the speed ofthe drill chuck is reduced to a stop, thus prevent-ing the run-on of the tool.
Any sparking occurring during this process in the
area of the upper ventilation slots is normal anddoes not damage the machine.
For screwdriving applications, wait until the screwis flush with the material and then release theOn/Off switch 7. The screw head does not pene-trate into the material then.
