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.
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:
When working with the machine, it must be held
with two hands.Always make sure that you have a
stable stance/foothold.
1.The mains power voltage must comply with the
information on the rating plate.
2. The TE505 is double insulated and
must not
be grounded/earthed.
3. Do not apply excessive pressure to the TE 505 –
this will not increase its performance. Simply posi-
tion 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
lubrication system.The connection ends of chisels
and other tools must therefore be cleaned regular-
ly and lubricated
sparingly
with Hilti grease.
Fig. 3: Side handle
Adjust the side handle as desired and lock it in
position.
Starting time at low temperatures:
The starting time (until hammering action operates)
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 connection
end,turn it until it clicks into place in the guide grooves
and thren release the locking sleeve.
To remove the chisel: Pull back the locking sleeve
and remove the chisel.
Fig. 4: Switching on
Set the chisel blade firmly against the work sur-
face and operate the switch.
Fig. 5: Constant on
For constant on operation, keep depressed the trig-
ger switch and press additionelly the locking bot-
ton to the right. To stop the constant on operation,
press the locking botton to the left.
Fig. 6: Positioning the chisel blade
Turn the switch to the symbol «0». Turn the chisel
blade to the desired working position and lock it by
switching to the chiseling symbol
.
Fig. 7: Regulating the hammering power
Set the TE 505 at the symbol «
larger hammer
100%» hammering power or at symbol «
small-
er hammer 50%» hammering power, position the
blade firmly on the work surface and chisel.
Servicing:
Fig. 7:
The TE 505 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 expen-
sive consequential damage.
Electric tools must
comply with the applicable safety regulations.
Servicing, therefore, must be carried out only by
qualified electrical specialists.The use of original
Hilti parts ensures optimum safety.
Chisel reforging and
resharpening:
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.
