Care And Maintenance - Hilti TE 706 Operating Instructions Manual

7.2 Operation
7.2.1 Activating the power tool (theft protection
system)
(Optional – not available with all versions.)
Further detailed information about activation and use of
this optional feature can be found in the separate oper-
ating instructions for the theft protection system.
1. Plug the supply cord into the power outlet. The yel-
low theft protection indicator lamp blinks. The power
tool is now ready to receive the signal from the acti-
vation key.
2. Hold the activation key close to the lock symbol. The
power tool is activated as soon as the theft protection
indicator lamp no longer lights.
-NOTE-
In the event of interruption of the electric supply to the
power tool, e.g. brief disconnection to move to a differ-
ent workplace, the power tool remains operational for
approx. 20 minutes. After a longer interruption, the power
tool must be reactivated by way of the activation key.

8. Care and maintenance

Unplug the supply cord form the power source.
8.1 Care of insert tools
Clean off dirt and dust deposits adhering to the insert
tools and protect them from corrosion by wiping the
insert tools from time to time with an oil-soaked rag.
Hilti polygon chisels require no resharpening.
8.2 Care of the power tool
-CAUTION-
Keep the power tool, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning agents
which contain silicone.
The outer casing of the tool is made from impactresis-
tant plastic. Sections of the grip are made from a syn-
thetic rubber material. Never operate the tool when the
ventilation slots are blocked. Clean the ventilation slots
carefully using a dry brush. Do not permit foreign objects
to enter the interior of the tool. Clean the outside of the
tool at regular intervals with a slightly damp cloth. Do not
use a spray, steam pressure cleaning equipment or run-
ning water for cleaning. This may negatively affect the
electrical safety of the tool.
8.3 Service indicator
The power tool is equipped with a service indicator.
8.3.1 The indicator lamp lights red

7.2.2 Chiseling
– The power tool and the chiseling operation emit noise.
Excessive noise may damage the hearing. Wear ear
protection.
– Chiseling 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.
-NOTE-
Working at low temperatures:
The hammering mechanism works only when the tool
has reached a minimum operating temperature.
Bring the drill bit into contact with the base material and
allow the tool to run under no load until the minimum
operating temperature is reached. If necessary, repeat
this procedure until the hammering mechanism begins
to operate.
7.2.2.1 Switching on
1. Plug the supply cord into the power outlet.
2. Press the on/off switch.
7.2.2.2 Switching off
1. Press the on/off switch.
After the lamp lights for the first time, the power tool
may continue to be used for approx. 10 days before the
automatic cut-out is activated. Bring the power tool to
a Hilti service center in good time so that the tool is
always ready for use when required.
8.3.2 The indicator lamp blinks red
A fault has occurred.
The power tool has been rendered inoperable. Return
the power tool to a Hilti service center for repair.
8.3.3 Protective cut-out
The power tool is equipped with an overheating pre-
vention cut-out. This cut-out may be activated without
any warning. The cut-out may also be activated (or the
power tool may refuse to start), without the indicator
lighting, if a fault in the electric supply is detected (see
section 9).
8.4 Maintenance
Check all external parts of the tool for damage at regu-
lar intervals and check that all controls operate fault-
lessly. Do not operate the tool if parts are damaged or
when the controls do not function faultlessly. If neces-
sary, your power tool should be repaired at a Hilti repair
center.
Repairs to the electrical section of the tool may be car-
ried out only by trained electrical specialists.
