Wide-flat chisel
As the cross-section of a worn wide-flat chisel is not
sufficient for reforging, these chisels should
not be
reforged
but only
resharpened
(ground).The blade
is long enough to be resharpened several times.

Before operating the
machine, please note:
Hold the machine securely with both hands while
working. Regularly check the security of the stance
or position from which you are working.
1. The main power voltage must comply with the
information on the rating plate.
2. Do not apply excessive pressure to the TE705
– this will not increase its performance. Simply
position and guide the chisel.
The enclosed list of safety precautions must
be observed.
Fig. 1: Cleaning chisel connection ends
The chuck is not incorporated in the machine’s lu-
brication system. The connection ends of chisels
and other tools must therefore be cleaned regu-
larly and lubricated
sparingly
with Hilti grease.
Starting time at low temperatures:
The starting time (until hammering action begins)
can be reduced by jolting the chisel once against
the working surface as the machine is switched
on.
Operation:
Fig. 2: Inserting a chisel
Pull back the locking sleeve, insert the chisel and
rotate it until it engages in the guide groove. Push
the chisel in further against the resistance of the
retaining mechanism and release the locking
sleeve.
To remove the chisel: Pull back the locking sleeve
and remove the chisel.
Fig. 3: Chisel adjustment
Pull back the locking sleeve as far as it will go (1),
rotate the chisel into the desired position (2), re-
lease the locking sleeve and the chisel engages in
position (3).
Fig. 4:
Adjust the side handle to the optimum working
position.Angle and axial adjustment is possible.
Fig. 5: Hammering power adjustment
Adjust the hammering power as required. By mov-
ing lever to the largest hammer symbol
j
for 100%
hammering power or to the smallest hammer sym-
bol
j
for 50% hammer power.
Beginning work:
Turn switch to on. Push chisel against base mate-
rial.
Servicing:
The TE 705 is equipped with a service indicator.
When the indicator lights up, the machine should
be serviced by Hilti.
Failure to service the ma-
chine when indicated could result in expensive
consequential damage.
Electric tools must com-
ply with the applicable safety regulations. Servicing,
therefore, must be carried out only by qualified elec-
trical specialists.The use of original Hilti parts pro-
vides optimum safety.
Chisel maintenance:
Resharpening:
When reshparpening wide-flat,narrow-flat and point-
ed chisels which are not badly worn at the cutting
edge, take care to avoid overheating the surface
(no discoloration!).
Resharpening limit: length of 70 mm from the tip.
Pointed and norrow-flat chisels
Reforge the chisel at about 1652°F to 823°F (900°C
to 1000°C) very bright red–bright yellowish red).
Afterwards, quench in oil
Forging and quenching the chisel in this way is all
that is required.
No further hardening and tempering is neces-
sary.
