Warranty
Hilti warrants that the tool supplied is free of
defects in material and workmanship. This war-
ranty is valid as long as the tool is operated and
handled correctly, cleaned and serviced properly
and in accordance with the Hilti Operating
Instructions, all warranty claims are made with-
in 12 months from the date of the sale (invoice
date), and the technical system is maintained.
This means that only original Hilti consumables,
components and spare parts may be used in the
tool.
This warranty provides the free-of-charge repair
or replacement of defective parts only. Parts re-
quiring repair or replacement as a result of nor-
mal wear and tear are not covered by this war-
ranty.
Additional claims are excluded, unless strin-
gent national rules prohibit such exclusion.
In particular, Hilti is not obligated for direct,
indirect, incidental or consequential dam-
ages, losses or expenses in connection with,
or by reason of, the use of, or inability to use
the tool for any purpose. Implied warranties
of merchantability or fitness for a particular
purpose are specifically excluded.
For repair or replacement, send tool and/or
related parts immediately upon discovery of the
defect to the address of the local Hilti marketing
organization provided.
This constitutes Hilti’s entire obligation with
regard to warranty and supersedes all prior or
contemporaneous comments and oral or written
agreements concerning warranties.
Shaped chisels – hollow/channel/wide-flat chis-
els
Slightly worn cutting edge:
Regrind carefully as
with pointed and flat chisel.
Badly worn cutting edge:
Reforge the chisel at a
temperature of 850
°
C to 1050
°
C (bright red–bright
yellow red).Harden the chisel by heating it to 850
°
C
to 900
°
C (bright red) before quenching it in oil. It
should then be tempered at 200
°
C to 300
°
C.
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
safe stance/foothold.
1. The mains voltage must comply with the infor-
mation 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. 7: 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: Locking
Press the locking switch to the left (towards the
chisel positioning lever) for sustained operation.
Press it to the right for on-off operation.
Fig. 5: 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. 6: Regulating the hammering power
Set the TE 505 at the symbol «
100%» or at sym-
bol «
50%»,position the blade firmly on the work
surface and chisel.
Fig. 3: Switching on
Set the chisel blade firmly against the work surface
and operate the switch. The TE 505 runs continu-
ously without maintaining pressure on the switch.
Press switch again to switch off.
Servicing:
Fig. 6:
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 maintenance:
Pointed and flat chisels:
Slightly worn cutting edge:
Grind the tip of the chis-
el carefully,without causing tempering colours to ap-
pear.This can be repeated several times if necessary.
Badly worn cutting edge:
Reforge the chisel at a
temperature of approx. 900
°
C to 1000
°
C (bright
red–bright yellow red). It should then be hardened
by heating to a temperature of 1000
°
C to 1100
°
C
(bright yellow red–yellow). Allow the chisel to cool
slowly (in the air – do not quench). Additional tem-
pering is not necessary.
