Preparation For Use; Operation - Hilti TE SX Mode D'emploi

Preparation for use

It is essential that the safety precautions print -
ed in these operating instructions are read
and observed.
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 ade-
quate cross section may be used. Failure to observe this
point may result in reduced performance of the tool and
overheating of the cord. Damaged extension cords must
be replaced. The recommended cross-sections and max.
length for extension cords are:
Recommended minimum conductor cross-section
Conductor cross-section
Mains voltage 1.5 mm
100 V 20 m
110–120 V
220–230 V 50 m
Use only insert tools with TE SX or TE-C resp. SDS con-
nection ends (fig. ).
Don't exert excessive pressure on the tool. This will not
increase its hammering power.
At low temperatures: The tool requires a minimum oper-
ating temperature before the hammering mechanism
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.
Choosing the drill bit
Use only drill bits with TE SX or TE-C resp. SDS con-
nection ends (fig. ).
Hilti power tools have been designed to work opti-
mally as a system together with Hilti drill bits. Accord-
ingly, highest performance and longest life expectan-
cy can be achieved when using this power tool with
Hilti drill bits.

To ensure optimum fastening quality, only SX-D drill
bits may be used when installing SX insulation fas-
teners.
Check your drill bits at regular intervals and replace
them in good time. A damaged or badly worn con-
nection 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 insulation fastenings.
Inserting the drill bit
a) Unplug the supply cord from the electrical
socket to prevent unintentional starting.
b) Check that the connection end of the drill bit is clean
and lightly greased. Clean it and grease it if neces-
sary . Check that the sealing lip of the dust shield
is clean. Wipe it off if necessary. Take care to ensure
that no drilling dust finds its way into the interior of
the chuck. The dust shield must be replaced when
the sealing lip is damaged. Please refer to the sec-
tion on care and maintenance.
c) Turn the chuck locking sleeve (fig.
III ( ) symbol. Push the drill bit into the chuck as
far as possible II and then rotate the insert tool until
the driving grooves engage and the tool can be pushed
all the way into the chuck. Turn the chuck locking
sleeve towards the I () symbol to lock the drill bit
in the chuck.
Drilling
– Drilling may cause splintering of the material. Splin-
ters may cause injury to parts of the body and eyes.
Wear eye protection, protective gloves and breath-
ing protection if no dust removal system is used.
– The tool and the drilling operation emit noise. Exces-
sive noise may damage the hearing. Wear ear protection.
– Switch the tool on only once it has been brought into
the working position close to the workpiece.
– Avoid contact with rotating parts.
– Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
a) Insert the supply cord plug in the mains socket.
b) Select desired drilling power by means of selector
switch for automatic function ON/OFF (fig.
ON-function: Tool starts with reduced r.p.m. and
hammering power. Used on hollow bricks with low
density and no plaster coating. Maximum holding
values of SX insulation fasteners will be achieved.
OFF-function: Full r.p.m. and hammering power.
Used on solid materials and masonry with plaster
coating to ensure a quick and secure setting of SX
insulation fasteners.
c) Position tool and drill bit at desired drill point and
press the electronic switch.
