CAUTION
The power tool must always be checked by a Hilti
specialist for internal or external damage whenever it
has been dropped or fallen over.
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.
7.2.1.1 Unlocking the power tool
1. Plug the supply cord into the power outlet. The
yellow theft protection indicator LED blinks. The
power tool is now ready to receive the signal from
the TPS key.
2. Hold the TPS key or the TPS watch strap buckle
against the lock symbol. The power tool is unlocked
as soon as the yellow theft protection indicator LED
no longer lights.
NOTE If, for example, the electric supply is briefly
interrupted due to a power failure or disconnected
when moving to a different workplace, the power
tool remains ready for operation for approx. 20 min-
utes. In the event of a longer interruption, the TPS
key must be used again to unlock the power tool.
7.2.1.2 Activation of the theft protection system for
the power tool
NOTE
Further detailed information on activation and use of the
theft protection system can be found in the operating
instructions for the theft protection system.
7.2.2 Chiseling
NOTE
Working at low temperatures: The hammering mecha-
nism works only when the power tool has reached a
minimum operating temperature. Bring the chisel into
contact with the base material and allow the power tool
to run under no load until the minimum operating tem-
perature is reached. If necessary, repeat this procedure
until the hammering mechanism begins to operate.
7.2.2.1 Chiseling
1. Plug the mains plug of the supply cord into the
power outlet.
2. Position the tip of the chisel at the point where
chiseling is to begin.
3. Press the on / off switch fully.
7.2.2.2 Switching off

8.2 Care of the power tool
The outer casing of the power tool is made from impact-
resistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power 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 power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool. Always keep the grip
surfaces of the power tool free from oil and grease. Do
not use cleaning agents which contain silicone.
