The long filter service life of STIHL air filters will ensure you can enjoy using your power tools for a long time to come. STIHL paper filters are also splash-proof thanks to the special coating on their surfaces. Clean filters increase engine performance, reduce fuel consumption and make starting the machine easier. This reliably protects your machine’s engine against the ingress of abrasive dust, helping tomaintain performance and keep fuel consumption low and ensuring that you can continue to start your power tool without difficulty. The fuel filter ensures that no foreign particles can enter the engine via the fuel. Regular replacement of this component protects the engine and ensures a long service life. It is also advisable to replace the spark plug regularly to maintain performance and ensure continued clean combustion in the engine.

When performing maintenance on the air filter and spark plug, it is best to use the practical combination socket toolsupplied with your STIHL power tool. A cardboard hook is integrated into the packaging of the service kit itself, which can be used to conveniently remove and replace the fuel filter. You don’t need any additional tools for the job.
