Specific Safety Rules And Symbols; Mechanical Hazards; Electrical Hazards - Hilti UH 240-A Manual De Instrucciones

Store idle tools out of reach of children and other
untrained persons.
Tools are dangerous in the hands of untrained users.
When battery pack is not in use, keep it away from
other metal objects like: paper clips, coins, keys, nails,
screws, or other small metal objects that can make a
connection from one terminal to another.
Shorting the battery terminals together may cause sparks,
burns, or a fire.
Maintain tools with care. Keep cutting tools sharp and
clean.
Properly maintained insert tools with sharp cutting edge
are less likely to bind and are easier to control.
Check for misalignment or binding of moving parts,
breakage of parts, and any other condition that may
affect the tool's operation. If damaged, have the tool
serviced before using.

3. Specific safety rules and symbols

Hold tool by insulating gripping surfaces when per-
forming an operation where the cutting tool may con-
tact hidden wiring.
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 Take the necessary precautions to make the
workplace safe
Concealed electric cables or gas and water pipes pre-
G
sent 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 con-
tact between your body and earthed / grounded objects,
such as pipes or radiators. External metal parts of the
tool may become live, for example, when an electric
cable is drilled into inadvertently.
Do not expose the tool to rain or snow.
G
Use the dust shield (accessory) to protect the chuck
G
when drilling overhead.
3.2 Additional general safety precautions
Printed: 07.07.2013 | Doc-Nr: PUB / 5071285 / 000 / 00
Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended by the
manufacturer for your model.
Accessories that may be suitable for one tool may cre-
ate a risk of injury when used on another tool.
2.6 Service
Tool service must be performed only by qualified repair
personnel.
Service or maintenance performed by unqualified per-
sonnel may result in a risk of injury.
When servicing a tool, use only identical replacement
parts. Follow instructions in the Maintenance section
of this manual.
Use of unauthorized parts or failure to follow Mainte-
nance Instructions may create a risk of shock or injury.
Keep the grips dry, clean and free from oil and grease.
G
Do not touch the chuck while it is rotating.
G
Never leave the tool unsupervised.
G
Switch the tool on only after bringing it into position
G
at the workpiece.
Do not insert wires or other similar objects into the
G
ventilation slots.
The tool may be operated only when the bit box is
G
closed.

3.2.1 Mechanical hazards

Check that the insert tools used are compatible with
G
the chuck system and that they are secured in the chuck
or gear housing correctly.
Use only original Hilti insert tools.

3.2.2 Electrical hazards

Ensure that the outer surfaces of the battery are clean
G
and dry before inserting it in the corresponding charger.
Use only the batteries listed in these operating instruc-
G
tions (see section 5).
Check that the battery is securely attached to the tool.
G
A falling battery could injure you or other persons.
Batteries that have reached the end of their life must
G
be disposed of safely (see section 12).
Ensure that batteries are charged using the correct
G
charger recommended by the manufacturer. Incorrect
