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-
gram of insert tools and accessories is available for the
TE-Y system

. The most important insert tools for
hammer drilling and chiselling are shown on the inside
of the toolbox. 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.
You can resharpen Hilti high quality chisels yourself very
easily. Your Hilti sales representative will be pleased to
provide instructions.
Please observe the instructions on care and mainte-
nance of your insert tools given in the following section.
8. 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.
drilling without hammering action. The function selec-
tor switch must be engaged in the hammer drilling posi-
tion (
).
Chiselling
The chisel can be adjusted to 24 different 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) Move the function selector switch to the centre posi-
tion

.
c) Select the position of the chisel (angle of the cutting
edge) by rotating the chuck

. Move the function
selector switch to the chiselling position ( )
until it engages

.
d) Select the desired chiselling power (II = full power, I
= half power)

. Working at the half-power setting
can be of advantage when chiselling brittle materials
(e.g. perforated brick) and when using bushing tools
for surface finishing.
e) Rotate side handle to the desired position. Ensure that
it is fitted correctly and tightened securely

. You
may also hold the tool at the chuck gripping section.
f) Connect the supply cord plug to the mains socket.
g) Bring the point of the chisel into contact with the 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 chiselling mode

.
To do so, push the red sliding switch located in the
grip above the control switch to the right, then press
the control switch fully.The tool is now in contant-
on operating mode. Always switch the tool off by
pushing the red sliding switch to the left, to its orig-
inal position.
If you do not intend to chisel in constant-on mode,
always push the red sliding switch located above the
control switch to the left position. Otherwise, the control
switch could unintentionaly be locked in constant-on
position when chiselling.
Never operate the function selector switch

while
the motor is running. When chiselling, the selector switch
must always be engaged in the chiselling position
(
).
When chiselling, never allow the chisel to penetrate the
base material at a constant angle. This may cause the
chisel to become stuck. Never use the chisel as a crow-
bar to break out material by applying force to it. This
may cause damage to the tool. Maximum removal per-
formance will be achieved when the chisel is guided at
