1) Without fuel, cutting tool and without protection
Brushcutters with a loop handle are just the right tool for trimming and thinning jobs, as well as for working without a harness. And in areas where space is limited.
The STIHL anti-vibration system is available in a one-point version for smaller models and in an espacially effective four-point version for larger machines starting with the STIHL. It reduces handle vibration for easy and comfortable operation.
A controller in the carburettor prevents the fuel-air mixture getting richer as the air filter becomes clogged. The correct quantity of fuel is delivered to the carburettor depending on the quantity of air passing through the air filter. This keeps the fuel/air ratio in the combustion mixture constant and hence also the engine power. The filter doesn't need to be cleaned until an appreciable drop in power occurs.
The decompression valve is part of the easy start-system. The valve reduces pressure in the cylinder which means less effort is required to start the engine.
STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the users joints and muscles through a spring or rubber element in the starter handle.
Manual fuel pump (Purger)
A small fuel pump delivers fuel to the carburettor at the touch of a button. This reduces the number of starting strokes required from a cold start.
Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.
