Standard features

Anti-vibration system:

Intense vibration at the handles of power tools can lead to longer-term effects of blood vessels in the hands and arms. STIHL have therefore developed an effective anti-vibration system where by the oscillations from the machines engine are dampened by rubber buffers. This significantly reduces vibrations at the handles allowing for more comfortable and safer operation.

Standard features

Bike handle:

When used in conjunction with a harness, the bike handle enables a smooth mowing action. Ideal for working on large areas and allows the machine to be easily guided, thus reducing fatigue.

Standard features

ElastoStart:

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.

Standard features

Shoulder strap / carrying system:

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

Standard features

Multi-function control handle:

This houses all the engine controls. Easy, comfortable thumb-operated control means the operator's hand never leaves the handle.
Close

Standard features

Compensator:

This 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.

Standard features

Tool free handle adjustment:

The central wing nut enables easy adjustment without the use of tools. For transportation and space-saving storage the handle can be rotated through 90°.

Standard features

Decompression valve:

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.
