Features

FR 450

Standard features

  • Loop handle (R) Zoom
    Loop handle (R)

    The loop handled grass trimmers and brushcutters are ideal for working in areas where space is limited, e.g. thinning between bushes and shrubs.

  • STIHL ElastoStart Zoom
    STIHL ElastoStart

    STIHL ElastoStart reduces the shock caused by the compression of the engine during starting. The compression shock is taken away from the user's joints and muscles through a spring or rubber element in the starter handle.

  • Manual fuel pump (Purger) Zoom
    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 pulls required following extended breaks in operations.

  • Anti-vibration system Zoom
    Anti-vibration system

    Intense vibration at the handles of power tools can lead to long-term effects on blood vessels in the hands and arms. STIHL has developed an effective anti-vibration system whereby the oscillations from the machine's engine are dampened which significantly reduces vibrations at the handles.

  • Multi-function control handle Zoom
    Multi-function control handle

    Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.

  • Shoulder strap / carrying system Zoom
    Shoulder strap / carrying system

    Using a STIHL shoulder strap or carrying harness with soft padding makes work more comfortable, particularly during lengthy jobs.

  • Decompression valve Zoom
    Decompression valve

    The decompression valve allows some of the compression pressure in the cylinder to escape, so less force on the starter rope is needed.

  • Compensator Zoom
    Compensator

    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.

  • Goggles Zoom
    Goggles

    It is important to protect your eyes from debris and harmful UV radiation. A pair of safety glasses is supplied with this machine. Please note, additional face protection must be worn when working with brushcutters.
