General safety rules
1. WARNING!
Read and understand all instructions.
Failure to follow all instructions listed below may result
in electric shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
2. Work Area
2.1 Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents.
2.2 Do not operate power tools in explosive atmos-
pheres, such as in the presence of flammable liquids,
gases, or dust. Power tools create sparks which may
ignite the dust or fumes.
2.3 Keep bystanders, children and visitors away while
operating a power tool. Distractions can cause you to
lose control.
3. Electrical Safety
3.1 Grounded tools must be plugged into an outlet
properly installed and grounded in accordance with
all codes and ordinances. Never remove the grounding prong or 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 the tools should electrically malfunction or
break down, grounding provides a low resistance path to
carry electricity away from the user.
Applicable only to Class I (grounded) tools.
3.2 Double insulated tools are equipped with a polar-
ized plug (one blade is wider than the other). This plug
will fit in a polarized outlet only one way. If the plug
does not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to install a
polarized outlet. Do not change the plug in any way.
Double insulation Z eliminates the need for the three-wire
grounded power cord and grounded power supply system.
Applicable only to Class II tools.
3.3 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 grounded.
3.4 Don’t expose power tools to rain or wet condi-
tions. Water entering a power tool will increase the risk of
electric shock.
This instruction need not be provided for tools classified
watertight or splashproof.
3.5 Do not abuse the cord. Never use the cord to car-
ry 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 cords
increase the risk of electric shock.
3.6 When operating a power tool outside, use an out-
door extension cord marked «W-A» or «W». These
cords are rated for outdoor use and reduce the risk of
electric shock.
4. Personal Safety
4.1 Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a
tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operat-
ing power tools may result in serious personal injury.
4.2. Dress properly. Do not wear loose clothing or
jewelry. Contain long hair. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes,
jewelry, or long hair can be caught in moving parts.
4.3 Avoid accidental starting. Be sure switch is off
before plugging in. Carrying tools with your finger on the
switch or plugging in tools that have the switch on invites
accidents.
4.4 Remove adjusting keys or wrenches before turn-
ing the tool on. A wrench or a key that is left attached to
a rotating part of the tool may result in personal injury.
4.5 Do not overreach. Keep proper footing and bal-
ance at all times. Proper footing and balance enables
better control of the tool in unexpected situations.
4.6 Use safety equipment. Always wear eye protection.
Dust mask, non-skid safety shoes, hard hat or hearing
protection must be used for appropriate conditions.
5. Tool Use and Care
5.1 Use clamps or other practical way to secure and
support the workpiece to a stable platform. Holding
the workpiece by hand or against your body is unstable
and may lead to loss of control.
5.2 Do not force tool. Use the correct tool for your
application.
safer at the rate for which it is designed.
5.3 Do not use tool if switch does not turn it on or off.
Any tool that cannot be controlled with the switch is dangerous and must be repaired.
5.4 Disconnect the plug from the power source
before making any adjustments, changing accessories, or storing the tool. Such preventive safety mea-
sures reduce the risk of starting the tool accidentally.
5.5 Store idle tools out of reach of children and other
untrained persons. Tools are dangerous in the hands of
untrained users.
5.6 Maintain tools with care. Keep cutting tools sharp
and clean. Properly maintained tools with sharp cutting
edges are less likely to bind and are easier to control.
5.7 Check for misalignment or binding of moving
parts, breakage of parts and any other condition that
may affect the tools operation. If damaged, have the
tool serviced before using. Many accidents are caused
by poorly maintained tools.
5.8 Use only accessories that are recommended by
the manufacturer for your model. Accessories that may
be suitable for one tool may become hazardous when
used on another tool.
6. Service
6.1 Tool service must be performed only by qualified
repair personnel. Service or maintenance performed by
unqualified personnel could result in a risk of injury.
6.2 When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or fail-
ure to follow Maintenance Instructions may create a risk
of electric shock or injury.
Additional Specific Safety Rules:
101 Hold tools by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord. Contact with a
«live» wire will make exposed metal parts of the tool «live»
and shock the operator.
102 Wear ear protectors when using the tool for
extended periods. Prolonged exposure to high intensity
noise can cause hearing loss.
The correct tool will do the job better and

Fig. 5: Selecting the correct
speed
If the wrong speed is selected,
the life of the TE25 and drill bit /
tool will be shortened. Select
the correct speed, as shown in
the following table:
1 = low r.p.m., 2 = high r.p.m.
Don’t change speeds while
the TE 25 is under load.

1. Power Source:
Before connecting your TE25 to
an outlet, insure that the power
supply is 115 volts AC, 50/60
Hz.
Shorten the start-up time at
low temperatures by jolting
the drill bit briefly against the
work surface when starting the
TE25.

which enables you to drill with
pinpoint accuracy.
● Use low drill speed (RPM) for
centering the drill bit in the base
material.
● Use full speed for drilling the
hole.
Light-duty chiselling
Using an additional chisel
adaptor from Hilti, the TE25 can
also be used for light chiselling
work in individual cases. Never

The connection end of the drill
bit should be cleaned regularly
and lubricated very sparingly
with Hilti grease.

The rotary action could cause
accidents and the life of the
TE25 will be greatly reduced.
Please refer to the separate
operating instructions for the
chisel adaptor.

The TE 25 can also be used for
rotary drilling using an additional quick-release chuck from
Hilti. Change this chuck as
