Safety rules
1. General safety rules
-WARNING- Read all instructions! Failure to follow all
instructions listed below may result in electric shock,
fire and/or serious injury. The term "power tool" in all of
the warnings listed below refers to your mains operat-
ed (corded) power tool or battery operated (cordless)
power tool.
SAVE THESE INSTRUCTIONS
1.1 Work area
a) Keep work area clean and well lit. Cluttered and
dark areas invite accidents.
b) Do not operate power tools in explosive atmos-
pheres, such as in the presence of flammable liq-
uids, gases or dust. Power tools create sparks which
may ignite the dust or fumes.
c) Keep children and bystanders away while operat-
ing a power tool. Distractions can cause you to lose
control.
1.2 Electrical safety
a) Power tool plugs must match the outlet. Never mod-
ify 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 elec-
tric shock.
b) Avoid body contact with earthed or grounded sur-
faces such as pipes, radiators, ranges and refrig-
erators. 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 car-
rying, 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 exten-
sion cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
1.3 Personal safety
a) Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use
a power tool while you are tired or under the influ-
ence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in
serious personal injury.
b) Use safety equipment. Always wear eye protec-
tion. Safety equipment such as dust mask, non-skid
safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal
injuries.
c) Avoid accidental starting. Ensure the switch is in
the off position before plugging in. Carrying power
tools with your finger on the switch or plugging in
power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turn-
ing the power tool on. A wrench or a key left attached
to a rotating part of the power tool may result in per-
sonal injury.
e) Do not overreach. Keep proper footing and balance
at all times. This enables better control of the pow-
er tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jew-
ellery. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewellery 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. Use of these devices
can reduce dust related hazards.
1.4 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 before
making any adjustments, changing accessories, or
storing power tools. Such preventive safety mea-
sures reduce the risk of starting the power tool acci-
dentally.
d) Store idle power tools out of the reach of children
and do not allow persons unfamiliar with the pow-
er tool or these instructions to operate the power
tool. Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool's oper-
ation. 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 main-
tained 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 and in the
manner intended for the particular type of power
tool, 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.
1.5 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 main-
tained.

2. Additional safety rules
2.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Use auxiliary handles supplied with the tool. Loss
of control can cause personal injury.
c) Always hold the tool with both hands on the grips
provided. Keep the grips dry, clean and free from
oil and grease.
d) Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
e) Avoid contact with rotating parts. Switch the tool on
only once it has been brought into the working posi-
tion close to the workpiece.
f) Breathing protection must be worn when the tool is
used without a dust removal system for work that
creates dust.
g) To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust extrac-
tion hose away to the rear.
h) When drilling or chiseling through-holes, check that
no person is present in the danger area immedi-
ately behind the work surface.
2.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to hold
the workpiece in place. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the tool.
b) Ensure that the insert tools used are equipped with
the appropriate connection end system and that
they are properly fitted and secured in the chuck.
c) In the event of a power faillure, switch the tool off
and unplug the supply cord. This prevents inadver-
tent starting when the power returns.
d) In the event of an interruption in the electric supply
and before laying the tool down each time, check
that the lockbutton for sustained operation has been
released. Release the lockbutton if necessary. Fail-
ure to observe this point could cause the tool to start
unexpectedly when the power returns.
e) Do not apply an excessive quantity of grease to the
drill bit connection end. Excess grease may other-
wise be forced out of the chuck during operation.
2.3 Electrical safety
a) Before beginning work, check the working area (e.g.
with a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
External metal parts of the tool may become live if,
for example, an electric cable is damaged inadvertenly.
This presents a serious risk of electric shock.
b) Check the condition of the supply cord and its plug
connections and have it replaced by a qualified elec-
trician if damage is found. Check the condition of
the extension cord and replace it if damage is found.
Do not touch the supply in the event of it suffering
damage while working. Disconnect the supply cord
plug from the socket. Damaged supply cords and
extension cords present a risk of electric shock.
c) Dirty or dusty electric tools should thus be checked
at a Hilti service center at regular intervals, espe-
cially if used frequently for working on conductive
materials. Dust (especially dust from conductive
materials) or dampness adhering to the surface of
the tool may, under unfavorable conditions, present
a risk of electric shock.
2.4 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.
Poorly ventilated workplaces may be injurious to the
health due to exposeure to dust.
2.5 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protection
and protective gloves when the tool is in use. Breath-
ing protection must be worn if no dust removal sys-
tem is used.

ed in these operating instructions are read and observed.
Fitting the side handle
1.Unplug the tool from the mains socket.
2. Release the side handle clamping band by turning
the handle in a counter-clockwise direction.
3. Fit the side handle clamping band over the chuck
and onto the cylindrical section at the front end of
the tool.
4. Pivot the side handle into the desired position.
5. Tighten the side handle securely to prevent inad-
vertent movement.
Check that the side handle is seated securely.
The supply voltage must correspond to the infor-
mation on the type plate.
If extension cords are used: Only extension cords
of a type approved for the intended use and of adequate
cross section may be used. Failure to observe this point
may result in reduced performance of the tool and over-
heating of the cord. Damaged extension cords must be
replaced.
Use only insert tools with TE-C connection end.
Don’t exert excessive pressure on the tool. This will not
increase its hammering power.

At low temperatures: The tool requires to reach a mini-
mum operating temperature before the hammering mech-
anism begins to operate. Switch on the tool and position
the tip of the drill bit on the work surface. While the tool
is running, apply light pressure briefly and repeatedly
until the hammering mechanism begins to operate.
Operation
CAUTION: In the event of the drill bit sticking, the tool
will pivot about its own axis.
Always use the tool with the side handle fitted and hold
it securely with both hands applying an opposing torque
so that the clutch releases in the event of the drill bit
sticking.
Use a vice or clamp to secure loose workpieces.
Fitting the insert tool 
1. Unplug the supply cord from the mains socket.
2. Check that the connection end of the insert tool is
clean and lightly greased. Clean it and grease it if nec-
essary.
3. Check that the sealing lip of the dust shield is clean
and in good condition. Clean the dust shield if nec-
essary or replace it if the sealing lip is damaged.
4. Push the connection end of the insert tool into the
chuck and, while applying slight pressure, rotate the
insert tool until it engages in the guide grooves.
5. Push the insert tool further into the chuck until it is
heard to engage.
6. Check that the insert tool has engaged correctly (pull
by hand).
Removing the insert tool
-CAUTION-
– The insert tool may become hot during use. There is
a risk of burning the hands. Wear protective gloves
when changing insert tools.
1. Unplug the supply cord from the mains socket.
2. Open the chuck by pulling back the locking sleeve.
3. Pull the insert tool out of the chuck.
Drilling
Hammer drilling (TE 2 / TE 2-E / TE 2-S / TE 2-M) /
precision hammering action (TE 2-S)
1. Insert the drill bit into the chuck.
5b
5a
2. Turn the function selection switch to the hammer
drilling position ( ) until the gearing is engaged
. Rotate the chuck spindle slightly if necessary.
Check that forwards rotation is selected (I.).
3. Use of the precision hammering action ( ) is advan-
tageous when drilling in brittle materials (e.g. tiles,
marble, perforated brick). This will improve the qual-
ity of the holes drilled .
4. Connect the supply cord to the power supply.
5. Pivot the side handle, with or without the depth gauge,
to the desired angle and tighten the handle to lock it
in this position. Check that the side handle is seated
and attached securely .
6. Bring the tip of the drill bit into contact with the work
surface at the position where the hole is to be drilled
and press the control switch slowly. Drill at low speed
until the drill bit centres itself in the hole.
7. Press the control switch fully and continue drilling at
full power.
Rotary-only drilling (without hammering action)
(TE 2 / TE 2-E / TE 2-S)
Turn the function selection switch to the drilling posi-
tion ( ) . When the switch is in this position, only the
rotary movement is transmitted to the TE-C insert tool
or chuck adaptor for insert tools with cylindrical shanks.
Rotary-only drilling (without hammering action)
(TE 2-M)
Turn the function selection switch to the 1st gear or 2nd
gear drilling position . When the switch is in these
positions, only the rotary movement is transmitted to
the TE-C insert tool or quick-release chuck.
Use of a high spindle speed can be advantageous when
drilling in metal or wood. For higher drilling speed, the
function selection switch must be engaged in the 2nd
gear position ( 2) .
Changing the chuck (TE 2-M)
Pull the chuck release ring towards the front and remove
the chuck completely. When fitting the chuck, pull the
release ring towards the front and hold it in this posi-
tion. Push the chuck onto the guide tube as far as it will
go and release the ring. Rotage the chuck until it engages
and the ring snaps back into its original position . The
TE-C interchangeable chuck or quick-release inter-
changeable chuck may be fitted to the TE 2-M with chuck
interface .
Drilling using the depth gauge
We recommend the use of the depth gauge for drilling
holes accurately to the desired depth. The depth gauge
is integrated in the side handle, which can be pivoted
and locked in position. Release the side handle (turn
counter-clockwise), set the depth gauge to the desired
drilling depth and tighten the side handle (turn clock-
wise) .

Care and maintenance
Care of the tool
The outer casing of the tool is made from impact-resis-
tant plastic. Grip sections, the dust shield and the sup-
ply cord protective sleeve are made from an elastomer
material.
Clean the outside of the tool at regular inter-
vals using a slightly damp cloth. Don’t use a spray, steam
pressure cleaning equipment or running water for clean-
ing. This may negatively affect the electrical safety of the
tool. Always keep the grip surfaces of the tool free from
oil and grease. Don’t use cleaning agents which contain
silicone.
Never operate the tool when the ventilation slots
are blocked. Clean the ventilation slots carefully using
a dry brush. Don’t permit foreign objects to enter the
interior of the tool.
Clean the dust shield on the chuck at regular intervals
using a clean, dry cloth. Carefully wipe the sealing lip
and grease it with a little Hilti grease. It is essential that
the dust shield is replaced when the sealing lip is dam-
aged. Proceed as follows: Insert a screwdriver at the
edge of the dust shield and lift it out in a forwards direc-
tion. Clean the contact surface and insert a new dust
shield. Press it in firmly until it engages.
Also take care of your insert tools. Clean off dirt and dust
deposits and protect your insert tools from corrosion
by wiping them from time to time with an oil-soaked rag.
Always keep the connection end clean and lightly greased.
Maintenance
Regularly check all external parts of the tool for
damage and to ensure that all controls operate fault-
lessly. Don’t operate the tool when parts are damaged
or when the controls do not function faultlessly. Have
your electric tool repaired by a Hilti service center.
Forwards / reverse rotation
(TE 2 / TE 2-S / TE 2-M)
For screwdriving, the desired direction of rotation can
be selected simply by moving the switch .
For forwards rotation, select position ( ) and for rever-
se rotation, select position ( ).
When the tool is operated in reverse rotation, the func-
tion selection switch should be engaged in the posi-
tion for drilling without hammering action ( / 1st gear).
For drilling, always ensure that forwards rotation
( ) is selected.
Insert tools and accessories
Use only insert tools with TE-C connection end or straight
shank bits with quick release chuck or adaptor .
Hilti power tools have been designed to work opti-
mally as a system together with Hilti insert tools.
Accordingly, highest performance and longest life
expectancy can be achieved when you use this pow-
er tool with Hilti insert tools. A comprehensive pro-
gramme of insert tools and accessories is available for
the TE-C system . Details of the entire programme
can be found in the current Hilti product catalogue.
Should you require insert tools not included in the stan-
dard programme, please contact the Hilti customer ser-
vice department or your Hilti sales representative. Hilti
offers a comprehensive range of special insert tools in
professional quality.
Check your insert tools at regular intervals and
replace them in good time. A damaged or badly worn
connection end may result in damage to the power tool.
Drill bits with chipped or broken carbide tips may no
longer drill holes of the specified diameter, thus influ-
encing their suitability for anchor fastenings.
Please observe the instructions on care and mainte-
nance of your insert tools given in the following section.
Dust removal (TE DRS-S) 
