The STIHL Blower Service Kits 37 lets you can carry out simple maintenance work on your blower saw yourself. Containing a HD2 Air Filter, Pre-Filter Spark Plug and Fuel Filter, these will increase the service life of your blower. And because of this, you yourself can help to ensure that machine components and parts are protected from dirt and damage and that the motor of your blower always works reliably and with optimum performance. The STIHL HD2 air filter is suitable for all operating conditions and can therefore be used universally. Thanks to its fine pores, it offers a very high filter quality and filters even the finest dirt from the intake air. By replacing the HD2 filter, the motor is reliably protected against the ingress of abrasive dust. The performance is retained, the consumption is low and you can continue to start your STIHL machine as easily as usual. You should also check the fuel filter so that no foreign particles enter the engine via the fuel. Regular replacement of these components protects the engine and supports its long service life. Changing the spark plug is also recommended so that clean combustion in the engine and thus optimal performance of your implement is possible. You do not need any additional tools for standard maintenance work. You can use the combination wrench from the scope of delivery of your blower or vacuum shredder to change the air filter and spark plug. A cardboard hook is integrated in the packaging of the service kit to release the fuel filter. On the cardboard box, there is a QR code for your smartphone that will link to a video explaining how to change each component.
