Stihl MS 500i

The electronic fuel injection control unit continuously calculates the correct fuel supply and the ideal ignition time, and injection is performed directly into the crankcase via the injection valve. Additionally, sensors measure air pressure and internal and external temperature, and pass information on to the control unit. This can use the identified values to determine the optimum fuel quantity and ignition timing. This means that your tool offers more power from a similar weight and installation space compared to engines without injection.

During work, your chainsaw uses a pressure and temperature sensor on the engine to measure the fuel. The control unit processes the values measured by the sensor so that the system adapts to the operating conditions. The optimised measurement of the fuel also achieves the best possible running behaviour.

Thanks to electronic fuel injection, your chainsaw does not need a start position. In addition, the manual fuel pump is easily accessible, making the start-up process even easier.

The STIHL Ematic system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a controlled-delivery oil pump. It ensures that the chain oil gets to where it is needed for lubrication. This allows you to reduce oil consumption by up to 50%. If you often work in dusty conditions or if you use long guide bars, you can quickly and easily increase the oil quantity at any time with the new oil pump system.

When it is time for a spot of maintenance, Stihl’s one piece removable engine cover makes access to the engine quick and easy. Adding chain oil and fuel is simple thanks to Stihl’s quick release tank caps. The semi-transparent fuel tank allows you to easily check the fuel level without opening the tank.

All our STIHL machines are run, checked and tuned and given full PDI (Pre-delivery Inspection) before leaving our premises. This means we will unpack your Stihl, start it, test it and individually tune it for maximum power and efficiency. We ensure that your machine is set up and ready to run when it is handed over to you.
