Safety Notes
General Power Tool Safety Warnings
Read all safety warnings and all instruc-
tions. 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 toolorbattery-operated(cordless)
power tool.
Work area safety
 Keepworkareacleanandwelllit.Clutteredordarkareas
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 which may ignite the 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 risk of electric shock.
 Avoidbodycontactwithearthedorgroundedsurfaces,
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 conditions.
Waterenteringapowertoolwillincreasetheriskofelectric
shock.
 Do not abuse the cord. Neveruse the cord for carrying,
pulling or unplugging the power tool. Keep cord away
from heat, oil, sharp edges and moving parts.Damaged
or entangled cords increase the risk of electric shock.
 When operating a power tool outdoors, use an exten-
sioncord suitablefor outdooruse. Use ofa cord suitable
for outdoor use reduces the risk of electric shock.
 If operating a power tool in a damp location is unavoid-
able, use a residual current device (RCD) protected
supply. Use of an RCD reduces the risk of electric shock.

Personal safety
 Stay alert, watch what you are doing and use common
sensewhenoperatinga power tool.Do notuse apower
toolwhileyouaretiredorundertheinfluenceofdrugs,
alcohol or medication. A moment of inattention while op-
erating power tools may result in serious personal injury.
 Use personal protective equipment. Always wear eye
protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection
used for appropriate conditions will reduce personal inju-
ries.
 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 en-
ergising power tools that have the switch on invites acci-
dents.
 Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a ro-
tating 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 jewel-
lery. Keep your hair, clothing and gloves away from
moving parts.Loose clothes, jewellery or long hair can be
caught in moving parts.
 If devices are provided for the connection of dust ex-
traction and collection facilities, ensure these are con-
nected and properly used. Use of dust collection can re-
duce dust-related hazards.
Power tool use and care
 Donotforcethepowertool.Usethecorrectpower tool
for your application. The correct power tool will do the
job better and safer at the rate for 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 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.
 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. Check for misalignment or bind-
ing of moving parts, breakage of parts and any other
conditionthat may affectthepower tool’s operation. If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained power
tools.
 Keepcuttingtoolssharpandclean.Properly maintained
cuttingtoolswithsharpcuttingedgesarelesslikelytobind
and are easier to control.
 Use the power tool, accessories and tool bits etc. in ac-
cordance 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.
Battery tool use and care
 Recharge only with the charger specified by the manu-
facturer. A charger that is suitable for one type of battery
pack may create a risk of fire when used with another bat-
tery pack.
 Use power tools only with specifically designated bat-
tery packs. Use of any other battery packs may create a
risk of injury and fire.
 When battery pack is not in use, keep it away from oth-
er 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 accidentally oc-
curs, flush with water. If liquid contacts eyes, addition-
ally seek medical help. Liquid ejected from the battery
may cause irritation or burns.
Service
 Haveyourpowertoolservicedbyaqualifiedrepairper-
son using only identical replacement parts. This will en-
sure that the safety of the power tool is maintained.
Hammer Safety Warnings
 Wear ear protectors. Exposure to noise can cause hear-
ing 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
maycontacthiddenwiring.Cuttingaccessorycontacting
a “live” wire may make exposed metal parts of the power
tool “live” and could give the operator an electric shock.
 Use appropriate detectors to determine if utility lines
are hidden in the work area or call the local utility com-
pany for assistance. Contact with electric lines can lead
to fire and electric shock. Damaging a gas line can lead to
explosion. Penetrating a water line causes property dam-
age.
 When working with the machine, always hold it firmly
with both hands and provide for a secure stance. The
power tool is guided more secure with both hands.
 Secure the workpiece. A workpiece clamped with clamp-
ing devices or in a vice is held more secure than by hand.
 Always wait until the machine has come to a complete
stop before placing it down. The tool insert can jam and
lead to loss of control over the power tool.
 Do not open the battery. Danger of short-circuiting.
Protect the battery against heat, e. g., against
continuous intense sunlight, fire, water, and mois-
ture. Danger of explosion.

EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications,withdifferentaccessoriesorinsertiontoolsoris
poorly maintained, the vibration emission may differ. This
may significantly increase the exposure level over the total
working period.
An estimation of thelevelofexposuretovibrationshouldalso
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working
period.

Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus tools are re-
quired that are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drill bits with cylindrical shank). For thesetools, a
keyless chuck or a key type drill chuck are required.
Inserting/Removing the Key Type Drill Chuck
(GBH 18V-26)
To work with tools without SDS-plus (e.g., drills with cylindri-
cal shank), a suitable drill chuck must be mounted (key type
drill chuck or keyless chuck, accessories).
Mounting the Key Type Drill Chuck (see figure E)
– Screw the SDS-plus adapter shank 25 into a key type drill
chuck 24. Secure the key type drill chuck 24 with the se-
curing screw 23. Please observe that the securing
screw has a left-hand thread.
Inserting the Key Type Drill Chuck (see figure E)
– Clean the shank end of the adapter shank and apply a light
coat of grease.

 A damaged dust protection cap should be changed im-
mediately. We recommend having this carried out by
an after-sales service.
Changing the Tool (SDS-plus)
Inserting SDS-plus Drilling Tools (see figure H)
The SDS-plus drill chuck allows for simple and convenient
changing of drilling tools without the use of additional tools.
– GBH 18V-26 F: Insert the SDS-plus quick change chuck 2.
– Clean and lightly grease the shank end of the tool.
– Insertthetoolinatwistingmannerintothetoolholderuntil
it latches itself.
– Check the latching by pulling the tool.
As a requirement of the system, the SDS-plus drilling tool can
move freely. This causes a certain radial run-out at no-load,
which has no effect on the accuracy of the drill hole, as the
drill bit centres itself upon drilling.
Removing SDS-plus Drilling Tools (see figure I)
– Push back the locking sleeve 5 and remove the tool.

Dust Extraction
 Dust from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful to
one’s health. Touching or breathing-in the dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– Asfaraspossible,useadust extractionsystemsuitable
for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dust can
easily ignite.

Reversing the rotational direction
The rotational direction switch 8 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 10 actuated.
Right rotation: Slide the rotational direction switch 8 all
the way to the left.
Leftrotation:Slidetherotationaldirectionswitch8allthe
way to the right.
Set the direction of rotation for hammer drilling, drilling and
chiselling always to right rotation.
Switching On and Off
To save energy, only switch the power tool on when using it.
– To start the machine, press the On/Off switch 10.
When starting the machine for the first time, a starting delay
is possible, as the electronic system of the power tool has to
configure itself first.
– To switch off the machine, release the On/Off switch 10.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on power tool can be
variablyadjusted,dependingonhowfartheOn/Offswitch10
is pressed.
Light pressure on the On/Off switch 10 results in low
speed/impact rate. Further pressure on the switch increases
the speed/impact rate.
Electronic Precision Control (EPC) (see figure A)
EPC assists you when working with impact in sensitive mate-
rials by ensuring slow start-up and reduced operating speed.

 If the tool insert becomes caught or jammed, the drive
tothedrillspindleisinterrupted.Becauseoftheforces
that occur, always hold the power tool firmly with both
hands and provide for a secure stance.
 If the power tool jams, switch the machine off and loos-
enthe toolinsert. Whenswitching themachineonwith
the drilling tool jammed, high reaction torques can oc-
cur.
Rapid Shut-off (Kickback Control)
The rapid shut-off feature (Kickback Control) provides better
control over the power tool to increase user protection com-
pared to power tools that do not have Kickback Control. The
power tool will switch off if it suddenly and unforeseeably ro-
tates around the drilling axis.
– To restart the machine, release the On/Off switch and
then actuate again.
Rapid shut-off is indicated by flashing of the worklight 14 on
the power tool.
Working Advice
Adjusting the Drilling Depth (see figure O)
The required drilling depth X can be set with the depth stop
17.
– Press the button for the depth stop adjustment 15 and in-
sert the depth stop into the auxiliary handle 16.
The knurled surface of the depth stop 17 must face down-
ward.
– Insert the SDS-plus drilling tool to the stop into the SDS-
plus tool holder 3. Otherwise, the movability of the SDS-
plus drilling tool can lead to incorrect adjustment of the
drilling depth.
– Pulloutthedepthstopuntilthedistancebetweenthetipof
the drill bit and the tip of the depth stop corresponds with
the desired drilling depth X.
Changing the Chiselling Position (Vario-Lock)
The chisel can be locked in 44 positions. In this manner, the
optimum working position can be set for each application.
– Insert the chisel into the tool holder.
– Turn the mode selector switch 13 to the “Vario-Lock” posi-
tion (see “Setting the operating mode”, page 20).
– Turn the tool holder to the desired chiselling position.
– Turn the mode selector switch 13 to the “chiselling” posi-
tion. The tool holder is now locked.
– For chiselling, set the rotation direction to right rotation.
Inserting Screwdriver Bits (see figure P)
 Apply the power tool to the screw/nut only when it is
switched off. Rotating tool inserts can slip off.
To work with screwdriver bits, a universal bit holder 31 with
SDS-plus shank (accessory) is required.
– Clean the shank end of the adapter shank and apply a light
coat of grease.
– Insert the universal bit holder with a turning motion into
the tool holder until it automatically locks.
– Check the locking effect by pulling the universal bit holder.
