Technical changes reserved.
The devices are manufactured in accordance with the provisions of EN ISO 11806-1 and fully comply with the provisions
of the German Product Safety Act.
Notice:
The vibration value indicated was determined with a standardized tool and can be used to make comparisons
with other petrol equipment as well as temporary estimates of the load through the vibrations.
WARNING!
The vibration value may vary according to the usage of the machine and its fitted equipment, and be
higher than the one indicated. Safety measures must be established to protect the user and must be based on the load
estimate generated by the vibrations in real usage conditions. In this regard, all the operational cycle phases must be
taken into consideration, such as switching off or idle running.
Warning:
Prolonged exposure to vibrations can cause injuries and neurovascular disorders (also called “Renaud’s
syndrome”or “white hand”), especially to people suffering from circulation disorders. The symptoms can regard the
hands, wrists and fingers and are shown through loss of sensitivity, torpor, itching, pain and discolouring of or structural
changes to the skin. These effects can be worsened by low ambient temperatures and/or by gripping the handgrips
excessively tightly. If the symptoms occur, the length of time the machine is used must be reduced and a doctor con-
sulted.
When working with the device, a certain level of noise cannot be avoided. Noisy work should be scheduled for hours,
during which it is allowed by statute or other local regulations. Adhere to any applicable rest times and limit your work-
ing time to the necessary minimum time. For your personal protection and the protection of people nearby, suitable
hearing protection must be worn.
