The cut-off saws’ STIHL Injection system does away with need for a choke and a starting throttle position. Thanks to automatic cold/hot detection, only one starting position is needed. The controller's intelligent system uses data like external temperature, altitude and fuel grade to automatically calculate the quantity of fuel needed when starting. That makes starting easier than ever: Simply move the switch from 0 to I, purge, start the engine and open the throttle. No chance of operator error!

Thanks to the new STIHL Injection system the cut-off saws’ engine power is also world class in its own right.   The 3.9 kW rated STIHL TS 480i and TS 500i deliver 20% higher cutting performance than the STIHL TS 410 and TS 420 cut-off saws. And they achieve that in almost the same space. In addition they drive high torque over a wide engine speed range, and that perceptibly increases their lugging ability. The STIHL TS 480i and TS 500i are also uncompromising when it comes to engine tuning: when the operating conditions change their engine control units keep them running sweetly and accelerating smoothly.

High torque over a wide engine speed range makes the STIHL TS 480i and TS 500i insensitive to feed pressure. The cut-off saws therefore pull steadily and produce an even cut.  The special top handle facilitates control during cuts that require a high level of precision. The absence of a carburettor makes the STIHL TS 480i and TS 500i  lightweight and designed for tough demands. They really show their strengths when working in confined conditions, thanks to the compact footprint and excellent power-to-weight ratio. In short, they provide precision control, leaving you free to concentrate fully on cutting.

STIHL Injection makes the two-stroke power unit simpler mechanically. The piston design has been simplified, making it lighter. As a result there is less oscillating mass in the cylinder and engine vibrations are decreased. In addition proven spring elements reduce the transmission of engine vibrations to the user's hands and arms. The vibration level is brought down to 2.2 m/s² (TS 480 i). That reduces operator fatigue and helps provide optimum control, even under the most difficult conditions.

Data on the cut-off saws’ engine status is continually measured while the units are operating. The controller automatically records any irregularities in the electronic components and stores them in the memory. That enables any deviations to be diagnosed during machine operation and read out later. An advantage no other STIHL machine offers to date.

The MDG 1 engine diagnosis unit makes servicing more straightforward than ever. Simply connect up the MDG 1 to the cut-off saw for an accurate diagnosis. All the electronic components are then checked with the aid of a special computer diagnosis program and the memory is read. That way, even occasional irregularities can be picked up and dealt with before they can develop into component failure. That ensures optimum servicing.

Saving time means saving money. Targeted servicing with the aid of the MDG 1 cuts the diagnosis time by 50% and frees up capacity in a servicing department.  At the same time rapid analysis permits targeted fault correction. The result is less delay, shorter downtimes and a faster return to work.

Automatic engine tuning cuts fuel consumption by up to 15% compared with the STIHL TS 410 and TS 420 cut- off saws. And the 0.7 kW higher engine power enables more material to be cut in the same time using the same amount of fuel. Speedy work and ultra-precise cutting are a matter of course. Because the electronically controlled STIHL Injection fuel injection system automatically adjusts all the settings during machine operation, optimum power and smooth running are ensured. When it comes to ruggedness too, the STIHL TS 480i and TS 500i set new quality standards. Well thought out down to the last detail, they are designed and built for heavy-duty construction site work.  Top quality from STIHL – that’s what you can rely on.
