3. Specific safety rules and symbols
Hold tools by insulated gripping surfaces when per-
forming an operation where the cutting tool may
contact hidden wiring or its own cord.
Contact with a
“live” wire will make exposed metal parts of the tool
“live” and shock the operator.
Wear ear protectors when using the tool for extended
periods.
Prolonged exposure to high intensity noise can
cause hearing loss.
3.1 Basic information concerning safety
In addition to the information relevant to safety given in
each of the sections of these operating instructions, the
following points must be strictly observed at all times.
3.2 Safety precautions at the workplace
●
Ensure that the workplace is well ventilated.
●
Keep the workplace tidy. Objects which could cause
injury should be removed from the working area.
Untidiness at the workplace can lead to accidents.
●
It is recommended that protective gloves and non-
slip shoes are worn when working outdoors.
●
Do not allow other persons to tamper with the tool
or the supply cord.
●
Avoid unfavorable body positions. Work from a secure
stance and stay in balance at all times.
●
To avoid tripping and falling when working, always
lead the supply cord, extension cord and dust extrac-
tion hose away to the rear.
●
Concealed electric cables or gas and water pipes pre-
sent a serious hazard if damaged while you are work-
ing. Accordingly, check the area in which you are work-
ing beforehand (e.g. using a metal detector). External
metal parts of the tool may become live, for example,
when an electric cable is drilled into inadvertently.
3.3 General safety precautions
●
Do not use the tool for purposes for which it was not
intended. Use the tool only as directed and when it
is in faultless condition.
●
Avoid contact with rotating parts.
●
Take the influences of the surrounding area into
account. Do not expose the tool to rain or snow and
do not use it in damp or wet conditions.
●
Keep the grips clean, dry and free from oil and grease.
●
The side handle must be fitted at all times when the
tool is in use.
●
Always hold the tool securely with both hands on the
grips provided.
●
When not in use, the tool must be stored in a dry
place, locked up or out of reach of children.
●
Switch the tool off before transporting it.
●
Take care of your insert tools. Observe the instructions
concerning lubrication and changing insert tools.
●
Check that moving parts function correctly without
sticking and that no parts are damaged. All parts
must be fitted correctly and fulfill all conditions nec-
essary for correct operation of the tool.
3.3.1 Mechanical hazards
●
Observe the instructions concerning care and main-
tenance.
●
Ensure that the insert tools used are equipped with
the appropriate connection end system and that they
are properly fitted and secured in the chuck.
●
Wear protective gloves when handling sharp insert
tools in order to avoid cutting your hands or fingers.
3.3.2 Electrical hazards
●
Check the condition of the extension cord and replace
it if damage is found.
●
Do not touch the supply cord in the event of it suf-
fering damage while working. Disconnect the sup-
ply cord plug from the socket.
●
Damaged or faulty switches must be replaced at a
Hilti service center.
●
Have the tool repaired only by a trained electrical
specialist (Hilti service center) using original Hilti
spare parts. Failure to observe this point may result
in risk of accident to the user.
●
In the event of a power failure, switch the tool off
and unplug the supply cord.
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.
