tection. Dust mask, non-skid safety shoes,
hardhat, orhearing protectionmust beused
for appropriate conditions.
4.Tool use and care
Use clamps or other practical way to secure and sup-
port the workpiece to a stable platform. Holding the
workby handor againstyour bodyis unstableand may
lead to loss of control.
Donot force tool.Usethecorrecttool for your applica-
tion. The correct tool will do the job better and safer at
the rate for which it is designed.
Do not use tool if switch does not turn it on or off.Any
tool that cannot be controlled with the switch is dan-
gerous and must be repaired.
Disconnectthe plug from thepowersource before mak-
ingany adjustments,changing accessories,orstoring
the tool.Such preventive safety measures reduce the
risk of starting the tool accidentally.
Storeidle tools out ofreachof children and otheruntrained
persons. Toolsare dangerousinthehandsofuntrained
users.

General safety rules
Warning! Read andunderstand allinstructions. Failure
tofollow allinstructions listedbelow,may resultin elec-
tric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
1.Work area
Keep your workarea clean and well lit. Clutteredbench-
es and dark areas invite accidents.
Do not operate power tools in explosive atmospheres,
suchas in the presenceofflammable liquids,gases,or
dust.Power tools create sparks which may ignite the
dust or fumes.
Keep bystanders,children,and visitors away while
operating a power tool. Distractions can cause you to
lose control.
2.Electrical safety
Groundedtools must be pluggedintoan outlet proper-
lyinstalled and grounded inaccordancewith all codes
andordinances.Never remove the grounding prongor
modify the plug in any way.Do not use any adaptor
plugs.Check with a qualified electrician if you are in
doubt as to whether the outlet is properly grounded.If
thetools shouldelectrically malfunctionor breakdown,
groundingprovides alow resistancepath tocarryelec-
tricity away from the user.
Applicable only to Class I (grounded) tools.
Double Insulated tools are equipped with a polarized
plug (one blade is wider than the other.) This plug will
fit in a polarized outlet only one way.If the plug does
notfit fully in theoutlet,reverse the plug.If it stilldoes
notfit,contact aqualifiedelectrician to install apolar-
ized outlet.Do not change the plug in any way.Double
InsulationZ eliminatestheneedforthe threewireground-
edpowercordand groundedpowersupply system.
Applicable only to Class II tools.
Avoid body contact with grounded surfaces such as
pipes,radiators,ranges and refrigerators.There is an
increased risk of electric shock if your body is ground-
ed.
Don’t expose power tools to rain or wet conditions.
Water enteringa powertool willincrease therisk ofelec-
tric shock.
Do not abuse the cord.Never use the cord to carry the
tools or pull the plug from an outlet.Keep cord away
from heat,oil,sharp edges or moving parts.Replace
damaged cords immediately. Damaged cordsincrease
the risk of electric shock.
When operating a power tool outside,use an outdoor
extensioncord marked "W-A"or "W".Thesecordsare
rated for outdoor use and reduce the risk of electric
shock.

Preparation for use
Itis essentialthat thesafety precautionsprint-
edin theseoperating instructionsare readand observed.
Thesupply voltagemust correspond tothe infor-
mation on the type plate.
Ifextension cordsare used:Only extensioncords
ofa typeapproved forthe intendeduse andof adequate
crosssection maybe used.Failure toobservethis point
mayresult inreduced performance ofthe tooland over-
heatingof thecord. Damagedextension cordsmust be
replaced. The recommended cross-sections and max.
length for extension cords are:
Conductor cross-section
mm2AWG
Voltage 1.5 2.0 2.5 3.5 14 12
110–120 V 20 m 30 m 40 m 50 m 75 ft 125 ft
Do not use 1.25 mm2and 16 AWG extension cords.
Use only insert tools with TE-Y connection end.
Don’texert excessivepressure onthe tool.This willnot
increase its hammering power.
Atlow temperatures:The toolrequires toreach amini-
mum operating temperature before the hammering
mechanism begins to operate. Switch on the tool and
positionthe tipof thedrill bitor chiselon thework sur-
face.While thetool isrunning, applylight pressurebriefly
andrepeatedly untilthe hammeringmechanism begins
to operate.
Operation
Operating from generators and transformers
This tool can be used on a generator and jobsite trans-
formers if it meets the following requirements:
–AC output 2600 W minimum; 24 A minimum
–120 V AC nominal; min. 102 V, max. 132 V under all
conditions
–frequency 50–60 Hz; never to exceed 65 Hz
–high dynamic automatic voltage regulator
Do not use other power tools on the generator/
transformer at the same time. Switching other tools
on/offcan causeundervoltageand/or overvoltage spikes
which could damage the tool.
Inserting the insert tool
a) Unplugthe supplycord fromthe electricalsock-
et to prevent unintentional starting.
b)Check that the connection end of the insert tool is
cleanand lightlygreased. Cleanit andgrease itif nec-
essary .Checkthatthesealinglipofthedustshield
5
isclean. Wipe itoff if necessary. Take care toensure
that no drilling dust finds its way into the interior of
the chuck. The dust shield must be replaced when
thesealing lipis damaged.Please referto thesection
on “care and maintenance“.
c) Insert the insert tool in the chuck and rotate it while
applyingslight pressureuntil itengages inthe guide
grooves. 
d)Pushthe inserttool infurther untilit isheard toengage.
Check that the insert tool has engaged correctly by
pulling on it. 
Removing the insert tool
a) Unplugthe supplycord fromthe electricalsock-
et to prevent unintentional starting.
b)Pull back the chuck locking sleeve and pull out the
insert tool .
Wear protective gloves. The insert tool
may be very hot after long periods of use.
Drilling
Hammer drilling
a) Insert drill bit into the chuck.
b)Move the selector switch to the hammer drilling
position ( ) until it engages .
c) Select the desired drilling power (II = full power,
I = half power) . When drilling in brittle materials
(e.g.perforatedbrick), drillingat thehalf-power set-
tingcan beof advantage.This mayimprove thequal-
ity of the hole drilled.
d)Rotate side handle to the desired position. Ensure
that it is fitted correctly and tightened securely .
e) Connect the supply cord to the power supply.
f) Bringthe tipof thedrill bitinto contactwith thework
surface atthe positionwhere thehole isto bedrilled
andpress thecontrol switchslowly. Drillat lowspeed
until the drill bit centers itself in the hole.
g)Pressthe controlswitch fullyand continuedrilling at
fullpower.When drillinga throughhole, reducedrilling
speedshortly beforethe drillbit breaksthrough. This
will reduce spalling around the hole.
Active Torque Control
TheTE76-ATCis equippedwith the Active Torque Con-
trol system in addition to the mechanical torque limit-
ing clutch. This system aids in maintaining control of
the tool in the drilling mode. If the drill bit catches, e.g.
on rebar, ATC is designed to help stop the tool, reduc-
ing the risk of an unwanted spin.
When the ATC system has activated, the tool can be
restartedby releasingthe controlswitch andre-engag-
ing it after the the motor has stopped rotating (“click“-
sound signals readiness for use).

6
Always choose a working position in which the tool is
free to rotate in a counter-clockwise direction (as
seen by the operator). If this is not possible, the ATC
system cannot react.
Drilling using the depth gauge (accessory)
We recommend the use of the depth gauge for drilling
holesto theexact depthrequired. Thedepth gaugerod
is offset in order to reduce deviations caused by tilting
thetool andto makeit easierto adjustthe drillingdepth
.
Assembly: Position thedepth gauge onthe top side
ofthe powertool sothat thetwo positioninglugs engage
inthe depressionsfor theflange screws.Press thedepth
gauge on to the tool until the two rear retaining lugs
engage in the tool casing. Insert the depth gauge rod
intothe depthgauge fromthe front,with theoffset end
towards the front of the tool.
Adjusting drilling depth : Slide the depth gauge rod
tothe requireddrilling depth.Adjust thefront endof the
depthgauge roduntil itis approx.10 mm(3/8″)fromthe
drill bit and then tighten the locking screw.
After use, remove the depth gauge and store it in the
toolbox.
Drilling without hammering action
Drillingwithout hammeringaction ispossible withinsert
toolswitha special connection end. Inserttools of this
kindare availablein theHilti inserttool program.Wood
drillbits orsteel drillbits withsmooth shankcan befit-
ted,for example,in thekeyless chuckand usedfor drilling
withouthammering action.The functionselector switch
mustbeengagedinthehammerdrillingposition( ).
Chiseling
Thechisel canbe adjustedto 24different positions.This
makes it possible to work with the cutting edge of flat
and shaped chisels at the optimum angle.
a) Insert the chisel into the chuck.
b)Movethe functionselector switchto thecenter posi-
tion .
c) Select the position of the chisel (angle of the cutting
edge) by rotating the chuck . Move the function
selectorswitch tothe chiselingposition ( )until
it engages .
d)Select the desired chiseling power (II = full power,
I= halfpower) . Workingatthe half-powersetting
can be of advantage when chiseling brittle materials
(e.g.perforatedbrick) andwhen usingbushing tools
for surface finishing.
e) Rotate side handle to the desired position. Ensure
thatit isfitted correctlyand tightenedsecurely .For
surfacefinishingwork,youmayalsoholdthetoolatthe
chuckgripping section.
f) Connectthe supply cordto thepowersupply.
g)Bringthe pointof thechisel intocontact withthe work
surface at the desired position. Press the control
switch slowly to enable precise starting and to pre-
vent the chisel slipping.
h)Press the control switch fully to chisel at full power.
i) If desired, the control switch can be locked in posi-
tion when the tool is operated in chiseling mode .
To do so, push the red sliding switch located in the
gripabove thecontrol switchto theright, thenpress
thecontrol switchfully. Thetool isnow incontant-on
operatingmode. Alwaysswitch thetool offby push-
ing the red sliding switch to the left, to its original
position.
Ifyou donot intendto chiselin constant-onmode,
always push the red sliding switch located above the
control switch to the left position. Otherwise, the con-
trol switch could unintentionaly be locked in the con-
stant-on position when chiseling.
Neveroperate thefunction selectorswitch  while
themotor isrunning. Whenchiseling, theselector switch
mustalwaysbeengagedinthechiselingposition( ).
When chiseling, never allow the chisel to penetrate the
base material at a constant angle. This may cause the
chiselto becomestuck. Neveruse thechisel asa crow-
bar to break out material by applying force to it. This
maycause damageto thetool. Maximumremoval per-
formance will be achieved when the chisel is guided at
a steep angle, working from the edge towards the low-
est point .
Care and maintenance
Care
Theouter casingof thetool ismade fromimpact-resis-
tant plastic. Grip sections, the dust shield and the sup-
ply cord protective sleeve are made from an elastomer
material.
Cleanthe outsideof thetool atregular inter-
valsusing aslightly dampcloth. Don’tuse aspray, steam
pressurecleaning equipmentor runningwater forclean-
ing.This maynegatively affectthe electricalsafety ofthe
