Cleaning the drill bit
The chuck is not included in the
machine's lubrication system. The drill
bit connection end should therefore be
cleaned at regular intervals and
sprayed sparingly with Hilti lubricant
spray, which is available as an acces-
sory.
Start-up time at low temperatures
Start-up time can be reduced by jolting
the drill bit against the work surface
when switching on.
Operation:
Fig.1: Inserting the drill bit
Turn chuck towards ( ) symbol and
insert the drill bit, turning it until the
drive grooves engage and it can be
pushed in fully. Lock the chuck by turn-
ing it towards the () symbol.
Fig.2: Hammer drilling
For hammer drilling in concrete mason-
ry and natural stone, adjust the setting
lever to the hammer drilling position
(
) symbol).
Drilling without hammering action
Adjust the setting lever to the rotary
drilling position (
symbol). When
set to this position, only the rotary
action is transmitted to the drill bit.
Fig.3: Reversing switch
The desired direction of rotation for
screwdriving can be selected with the
reversing switch. For counter-clockwise

rotation, the setting lever must be in the
rotary drilling position (no hammering
action). Counter-clockwise rotation
should only be used for short periods.
Fig.4: Changing the chuck
Pull the sleeve forwards to remove the
complete chuck. To replace the chuck,
pull the sleeve forwards and hold it in
that position. Slide the chuck onto the
guide as far as it will go and release the
sleeve. Turn the chuck until the balls
engage and the sleeve snaps back into
position.
Fig. 5: Side handle / depth gauge
The side handle can be turned through
360° and locked in the desired position.
Release the side handle by turning it
counter-clockwise, set the desired
drilling depth with the depth gauge and
then lock the side handle by turning it
clockwise.
Note: When the key-type chuck is fit-
ted, the hammering action cuts out
automatically (rotary drilling only).
Inserting the cylindrical connection end:
Open the key-type chuck to the
required diameter, insert the drill bit as
far as it will go and tighten using the
key. The key-type chuck can also be
used for counter-clockwise rotation.
Servicing:
Electric tools must conform to the
applicable safety regulations. Servicing
must only be carried out by a trained
electrical specialist. The use of original
Hilti spare parts ensures optimal safety.
Double insulation
The Hilti TE 5 Rotary Hammer is dou-
ble-insulated for extra operator protec-
tion. The tool is equipped with a two-
wire cord and two-prong plug which can
be used on standard 115 volts outlets.
No grounding of the tool is necessary.
Extension cords
Use an extension cord heavy enough to
carry the current your tool requires. An
undersized cord will cause a drop in
voltage, resulting in loss of power and
overheating. The following list shows
the correct size to use depending on
cord length. If in doubt, use the next
heavier gauge.
Note: The smaller the gauge number,
the heavier the cord. See your Hilti
sales representative for extension
cords. The following are recommended
American Wire Gauges (AWG) for your
