2 Safety
2.1 General power tool safety warnings
WARNING Read all safety warnings, instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated
(cordless) power tool.
*2321711* 2321711 English 3
Work area safety
▶Keep work area clean and well lit. Cluttered or dark areas invite accidents.
▶Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
▶Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
Electrical safety
▶Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter
plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of
electric shock.
▶Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
▶Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
▶Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the
risk of electric shock.
▶When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a
cord suitable for outdoor use reduces the risk of electric shock.
▶If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.
Personal safety
▶Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A
moment of inattention while operating power tools may result in serious personal injury.
▶Use personal protective equipment. Always wear eye protection. Protective equipment such as a
dust mask, non-skid safety shoes, hard hat or hearing protection used for appropriate conditions will
reduce personal injuries.
▶Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power
source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on
the switch or energising power tools that have the switch on invites accidents.
▶Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left
attached to a rotating part of the power tool may result in personal injury.
▶Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
▶Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
▶If devices are provided for the connection of dust extraction and collection facilities, ensure these
are connected and properly used. Use of dust collection can reduce dust-related hazards.
▶Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore
tool safety principles. A careless action can cause severe injury within a fraction of a second.
Power tool use and care
▶Do not force the power tool. Use the correct power tool for your application. The correct power tool
will do the job better and safer at the rate for which it was designed.
▶Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be
controlled with the switch is dangerous and must be repaired.
▶Disconnect the plug from the power source and/or remove the battery pack, if detachable, from
the power tool before making any adjustments, changing accessories, or storing power tools.
Such preventive safety measures reduce the risk of starting the power tool accidentally.
▶Store idle power tools out of the reach of children and do not allow persons unfamiliar with the
power tool or these instructions to operate the power tool. Power tools are dangerous in the hands
of untrained users.
▶Maintain power tools and accessories. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tool’s operation. If damaged,
have the power tool repaired before use. Many accidents are caused by poorly maintained power
tools.
▶Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
4 English 2321711 *2321711*
▶Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed. Use of the power tool for
operations different from those intended could result in a hazardous situation.
▶Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

2 Seguridad
2.1 Indicaciones generales de seguridad para herramientas eléctricas
ADVERTENCIA Lea con atención todas las indicaciones de seguridad, instrucciones, ilustraciones
y datos técnicos correspondientes a esta herramienta eléctrica. La negligencia en el cumplimiento
de las instrucciones que se describen a continuación podría provocar descargas eléctricas, incendios o
lesiones graves.
Conserve todas las instrucciones e indicaciones de seguridad para futuras consultas.
El término «herramienta eléctrica» empleado en las indicaciones de seguridad se refiere a herramientas
eléctricas portátiles, ya sea con cable de red o sin cable, en caso de ser accionadas por batería.
Seguridad en el puesto de trabajo
▶Mantenga su área de trabajo limpia y bien iluminada. El desorden o una iluminación deficiente de las
zonas de trabajo pueden provocar accidentes.
▶No utilice la herramienta eléctrica en un entorno con peligro de explosión en el que se encuentren
líquidos, gases o polvos inflamables. Las herramientas eléctricas producen chispas que pueden llegar
a inflamar los materiales en polvo o vapores.
▶Mantenga alejados a los niños y otras personas de su puesto de trabajo al emplear la herramienta
eléctrica. Una distracción le puede hacer perder el control sobre la herramienta.
Seguridad eléctrica
▶El enchufe de la herramienta eléctrica debe corresponder a la toma de corriente utilizada.
No se deberá modificar el enchufe en forma alguna. No utilice enchufes adaptadores para las
herramientas eléctricas con puesta a tierra. Los enchufes sin modificar adecuados a las respectivas
tomas de corriente reducen el riesgo de descarga eléctrica.
▶Evite el contacto corporal con superficies que tengan puesta a tierra, como pueden ser tubos,
calefacciones, cocinas y frigoríficos. El riesgo a quedar expuesto a una sacudida eléctrica es mayor
si su cuerpo tiene contacto con tierra.
▶No exponga las herramientas eléctricas a la lluvia y evite que penetren líquidos en su interior. El
riesgo de recibir descargas eléctricas aumenta si penetra agua en la herramienta eléctrica.
▶No utilice el cable de conexión para transportar o colgar la herramienta eléctrica ni tire de él para
extraer el enchufe de la toma de corriente. Mantenga el cable de conexión alejado de fuentes de
calor, aceite, aristas afiladas o piezas móviles. Los cables de conexión dañados o enredados pueden
provocar descargas eléctricas.
▶Cuando trabaje al aire libre con una herramienta eléctrica, utilice exclusivamente un alargador
adecuado para exteriores. La utilización de un alargador adecuado para su uso en exteriores evita el
riesgo de una descarga eléctrica.
▶Cuando no pueda evitarse el uso de la herramienta eléctrica en un entorno húmedo, utilice un
interruptor de corriente de defecto. La utilización de un interruptor de corriente de defecto evita el
riesgo de una descarga eléctrica.
Seguridad de las personas
▶Permanezca atento, preste atención durante el trabajo y utilice la herramienta eléctrica con
prudencia. No utilice una herramienta eléctrica si está cansado, ni tampoco después de haber
consumido alcohol, drogas o medicamentos. Un momento de descuido al utilizar la herramienta
eléctrica podría producir graves lesiones.
▶Utilice el equipo de seguridad personal adecuado y lleve siempre gafas protectoras. El riesgo
de lesiones se reduce considerablemente si, según el tipo y la aplicación de la herramienta eléctrica
empleada, se utiliza un equipo de seguridad personal adecuado como una mascarilla antipolvo, zapatos
de seguridad con suela antideslizante, casco de protección o protección para los oídos.
▶Evite una puesta en servicio fortuita de la herramienta. Asegúrese de que la herramienta eléctrica
está apagada antes de alzarla, transportarla, conectarla a la toma de corriente o insertar la
batería. Si transporta la herramienta eléctrica sujetándola por el interruptor de conexión/desconexión
o si introduce el enchufe en la toma de corriente con la herramienta conectada, podría producirse un
accidente.
▶Retire las herramientas de ajuste o llaves fijas antes de conectar la herramienta eléctrica. Una
herramienta o llave colocada en una pieza giratoria puede producir lesiones al ponerse en funcionamiento.
▶Evite adoptar posturas forzadas. Procure que la postura sea estable y manténgase siempre en
equilibrio. De esta forma podrá controlar mejor la herramienta eléctrica en caso de presentarse una
situación inesperada.
▶Utilice ropa adecuada. No utilice vestimenta amplia ni joyas. Mantenga su pelo, vestimenta y
guantes alejados de las piezas móviles. La vestimenta suelta, las joyas y el pelo largo se pueden
enganchar con las piezas en movimiento.
16 Español 2321711 *2321711*
▶Siempre que sea posible montar equipos de aspiración o captación de polvo, asegúrese de que
están conectados y de que se utilizan correctamente. El uso de un sistema de aspiración de polvo
reduce los riesgos derivados del polvo.
▶No se crea a salvo de cualquier riesgo ni pase por alto ninguna de las normas de seguridad
relativas a las herramientas eléctricas, aun cuando esté familiarizado con la herramienta eléctrica
y tenga larga experiencia en su uso. Una actuación negligente puede provocar lesiones graves en
cuestión de segundos.
Uso y manejo de la herramienta eléctrica
▶No sobrecargue la herramienta. Utilice la herramienta eléctrica adecuada para el trabajo que se
dispone a realizar. Con la herramienta eléctrica apropiada podrá trabajar mejor y de modo más seguro
dentro del margen de potencia indicado.
▶No utilice herramientas eléctricas con el interruptor defectuoso. Las herramientas eléctricas que no
se puedan conectar o desconectar son peligrosas y deben repararse.
▶Extraiga el enchufe de la toma de corriente o retire la batería extraíble antes de efectuar cualquier
ajuste en la herramienta, cambiar accesorios o en caso de no utilizar la herramienta durante un
tiempo prolongado. Esta medida preventiva evita el riesgo de arranque accidental de la herramienta
eléctrica.
▶Guarde las herramientas eléctricas que no utilice fuera del alcance de los niños. No permita
utilizar la herramienta a ninguna persona que no esté familiarizada con ella o que no haya leído
este manual de instrucciones. Las herramientas eléctricas utilizadas por personas inexpertas son
peligrosas.
▶Cuide su herramienta eléctrica y los accesorios adecuadamente. Compruebe si las piezas móviles
de la herramienta funcionan correctamente y sin atascarse, y si existen piezas rotas o deterioradas
que pudieran afectar al funcionamiento de la herramienta eléctrica. Encargue la reparación de las
piezas defectuosas antes de usar la herramienta eléctrica. Muchos accidentes son consecuencia de
un mantenimiento inadecuado de la herramienta eléctrica.
▶Mantenga los útiles limpios y afilados. Las herramientas de corte bien cuidadas y con aristas afiladas
se atascan menos y se guían con más facilidad.
▶Utilice la herramienta eléctrica, los accesorios, útiles de inserción, etc., de acuerdo con estas
instrucciones. Para ello, tenga en cuenta las condiciones de trabajo y la tarea que se va a realizar.
El uso de herramientas eléctricas para trabajos diferentes de aquellos para los que han sido concebidas
puede resultar peligroso.
▶Mantenga las empuñaduras y las superficies de contacto secas, limpias y sin residuos de aceite
o grasa. Las empuñaduras y superficies de contacto resbaladizas impiden manejar y controlar la
herramienta eléctrica con seguridad en situaciones imprevistas.
Uso y manejo de la herramienta de batería
▶Cargue las baterías únicamente con los cargadores recomendados por el fabricante. Existe riesgo
de incendio al intentar cargar baterías de un tipo diferente al previsto para el cargador.
▶Utilice únicamente las baterías previstas para la herramienta eléctrica. El uso de otro tipo de
baterías puede provocar daños e incluso incendios.
▶Si no utiliza la batería, guárdela separada de clips, monedas, llaves, clavos, tornillos y demás
objetos metálicos que pudieran puentear sus contactos. El cortocircuito de los contactos de la
batería puede causar quemaduras o incendios.
▶La utilización inadecuada de la batería puede provocar fugas de líquido. Evite el contacto con
este líquido. En caso de contacto accidental, enjuague el área afectada con abundante agua. En
caso de contacto con los ojos, acuda además inmediatamente a un médico. El líquido de la batería
puede irritar la piel o producir quemaduras.
▶No utilice baterías dañadas o modificadas. Una batería dañada o modificada puede tener un
comportamiento imprevisible y provocar incendios, explosiones o riesgo de lesiones.
▶No exponga la batería al fuego o a temperaturas muy elevadas. El fuego o las temperaturas
superiores a 130 °C (265 °F) pueden provocar una explosión.
▶Siga todas las instrucciones relativas a la carga y no cargue nunca la batería o la herramienta de
batería excediendo el rango de temperatura indicado en el manual de instrucciones. Una carga
incorrecta o fuera del rango de temperatura permitido puede destruir la batería y aumentar el riesgo de
incendio.
Servicio Técnico
▶Solicite que un profesional lleve a cabo la reparación de su herramienta eléctrica y que utilice
exclusivamente piezas de repuesto originales. Solamente así se garantiza la seguridad de la
herramienta.
