Instrucciones generales de seguridad
ADVERTENCIA: Lea atentamente
las instrucciones de advertencia siguientes
antes de usar el producto.
• El uso incorrecto o descuidado del producto puede
convertirlo en una herramienta peligrosa que puede
causar heridas graves o daños mortales. Es muy
importante que lea y comprenda el contenido de
este manual de usuario.
• En este producto se genera un campo
electromagnético durante su funcionamiento. Este
campo puede, en determinadas circunstancias,
interferir con implantes médicos activos o pasivos.
Para reducir el riesgo de lesiones graves o fatales,
recomendamos a las personas con implantes
médicos consultar a su médico y al fabricante del
implante médico antes de usar esta máquina.
• La sobreexposición a las vibraciones puede producir
trastornos vasculares o nerviosos en personas que
padecen de trastornos circulatorios. Póngase en
contacto con su médico si experimenta síntomas de
la sobreexposición a las vibraciones. Estos síntomas
son entumecimiento, pérdida de sensibilidad,
hormigueo, ardor, dolor, pérdida de fuerza, cambios
en el color o el estado de la piel. Normalmente,
estos síntomas se presentan en los dedos, manos o
muñecas. El riesgo aumenta a bajas temperaturas.
• Si se encuentra en una situación en la que no está
seguro de cómo proceder, debe preguntarle a un
experto. Póngase en contacto con el distribuidor o el
taller de servicio. Evite todos los usos que considere
que están más allá de su capacidad.
• Tenga en cuenta que el operador es responsable de
los accidentes o los peligros que ocurren a otras
personas o sus propiedades.
• Nunca permita que otras personas utilicen el
producto sin asegurarse primero de que hayan
comprendido el contenido del manual del usuario.
• Nunca permita que los niños utilicen el producto o
que estén cerca de este. Debido a que el producto
está equipado con un interruptor de detención que
se acciona por resorte y se puede arrancar con baja
velocidad y fuerza desde la empuñadura de
arranque, incluso niños pequeños pueden, en
determinadas circunstancias, lograr la fuerza
necesaria para arrancar el producto. Esto puede
significar riesgo de daños personales graves. Por
consiguiente, saque el sombrerete de bujía cuando
no se supervise el producto atentamente.
• Almacene el producto fuera del alcance de los niños.
• Nunca utilice el producto si está cansado, si ha
ingerido alcohol o si toma medicamentos que
puedan afectarle la vista, su capacidad de
discernimiento o su coordinación.
• Nunca utilice un producto que esté defectuoso.
Realice las comprobaciones de seguridad, el
mantenimiento y las instrucciones de servicio
descritas en este manual. Especialistas capacitados
y calificados deben llevar acabo algunas medidas de
mantenimiento y servicio. Consulte las instrucciones
en el capítulo Mantenimiento.
• Nunca utilice un producto que se haya modificado
de cualquier modo con respecto a la especificación
original.

Equipo de protección personal
ADVERTENCIA: Lea atentamente
las instrucciones de advertencia siguientes
antes de usar el producto.
