WARNING
All the machines and accessories undergo continuous development.
The manufacturer reserves the right to modify technical data, weights,
construction characteristics and standard equipment at any time and without
notice.
DANGER
If the cutting tools are not in position and appropriately secured, they may cause
SERIOUS DAMAGE TO PEOPLE AND PROPERTY.
The manufacturer accepts no responsibility if the instructions provided in this manual are not
followed.
3.1 Intended use
The brushcutter must be used exclusively to cut grass, shrubs and bushes.
3.2 Improper use
Improper use means the incorrect use of the machine that does not result in potential accidents,
but may cause serious damage to the machine itself.
Modifying or adjusting the machine in order to obtain a level of performance that is higher or
different to that provided by the manufacturer is considered IMPROPER USE and therefore the
manufacturer declines all liability for injury to persons or damage to property; the machine
warranty will be considered void.
3.3 Inappropriate use and contraindications
CAUTION

• setting it up in a way that is not compliant with the instructions in this manual;
• in explosive atmospheres or in places where there is a fire hazard;
• processing materials other than those intended by the manufacturer;
• dangerous situations or device malfunctions;
• improper use of the machine or use by untrained personnel;
• use contrary to the relevant regulations;
• if there are defects in the fuel supply system of the engine;
• if maintenance has not been carried out;
• after modifications or non-authorized interventions;
• failure to comply with some or all of the instructions provided;
• use with materials and tools different from those intended by the manufacturer.
