Use and Care Manual

CAUTION
Remove the insert tool before laying the power
tool down or placing it on the transport trolley.
Disconnect the mains plug from the power outlet.
Unintentional starting (accidental contact with the on
/ off switch) may cause the power tool to kick.
7.2.1 TPS Theft Protection System (optional)
NOTE
The power tool may be equipped with the optional
theft protection system. If the power tool is equipped
with this feature, it can be unlocked and made ready
for operation only through use of the corresponding
TPS key.
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 un-
locked 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
minutes. 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 mech-
anism 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 operat-
ing temperature 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
Release the on / off switch.
8. Care and maintenance
CAUTION
Disconnect the mains plug from the power outlet.
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.
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.
