Specific safety rules and symbols

Use protective
equipment.
Check the tool each time before use.
Check the condition of the tool, the supply cord,
power plug and hoses. Don't use it if it is damaged,
incomplete or if the controls cannot be operated cor-
rectly. If parts are damaged or missing, have the tool
repaired at an authorized Hilti service center.
Use the correct insert tool.
Ensure that the core bits are equipped with the appro-
priate connection end for the chuck system in use and
that they are locked in position correctly in the chuck.
Use only the recommended original Hilti accessories
and auxiliary equipment.
Use the tool only for the purposes for which it is intended.
Apply a safe working method.
Avoid unfavourable body positions. Always ensure
that you have a safe and stable stance. Always hold
the tool in both hands when it is in use. Always use
the side handle. Ensure that the side handle is fitted
correctly and tightened securely
Hold the tool securely when drilling and pay attention
at all times. Switch the tool off if you are distracted
from your work.
When the tool is in use, always guide the supply
cord away from the tool to the rear.
Never carry the tool by the supply cord. Don't unplug
the tool by pulling on the supply cord. Don't expose
the supply cord to heat, oil or sharp edges. If the sup-
ply cord becomes damaged while working, don't touch
it – unplug the power plug immediately.
Check that the blades of the plug and supply cord are
clean and dry before it is connected. Unplug the sup-
ply cord form the power socket before cleaning.

6.2 When servicing a tool, use only identical replace-
ment parts. Follow instructions in the Maintenance
section of this manual. Use of unauthorized parts or
failure to follow Maintenance Instructions may create a
risk of electric shock or injury.
Always wear protective
clothing.
Take care to avoid concealed cables and pipes.
Concealed electric cables or gas and water pipes
present a serious hazard if damaged while you
are working. Accordingly, check the area in
which you are working beforehand (e.g. using
a metal detector). Avoid contact between your body
and grounded objects such as pipes or radiators. Exter-
nal metal parts of the tool may become live, for exam-
ple, when an electric cable is drilled into inadvertently.
The power to cables (or water, gas etc. in pipes) locat-
ed where drilling work is to take place must be switched
off.
Avoid unintentional starting.
Do not carry the tool with your finger on the control
switch while it is connected to the power supply. Check
that the tool is switched off and that the trigger switch
lockbutton is released before connecting it to the pow-
er supply or before connecting the supply cord to the
tool. Disconnect the plug from the power socket when
the tool is not in use, e.g. during pauses between work,
before maintenance and when changing insert tools.
Keep the electric tool and insert tools in good
condition.
Follow the care and maintenance instructions and
replace insert tools in good time. Never operate the
tool when it is dirty or wet. Dust or dampness on the
surface of the tool make it slippery and difficult to hold
and may, under unfavourable conditions, present a risk
of electric shock.
Repairs to the tool may be carried out only by an autho-
rized electrical specialist using original Hilti spare
parts. Failure to observe this point may result in dam-
age to the tool or present a risk of accident. According-
ly, if necessary, have the tool repaired at a Hilti service
center or authorized Hilti repair workshop.
When setting anchors, follow all anchor instal-
lation instructions and applicable testing / inspec-
tion regulations.
Store the tool in dry area if it is not in use.
Symbols used on the tool:
Always wear protective
gloves.
