Service Kit 16 – For MS 661

With Service Kit 16 for STIHL petrol chainsaws you can carry out simple maintenance work on your chainsaw yourself. Regular standard maintenance, such as replacing the air and fuel filters and the spark plug, increases the service life of your chainsaw. 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 chainsaw always works reliably and with optimum performance.

Service Kit 16 for MS 661 includes the following components for standard maintenance:

• HD2 air filter
• Spark plug
• Fuel filter

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 chainsaw 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 chainsaw as easily as usual.

In order to maintain performance, it is also recommended to replace the spark plug regularly. This is the basis for clean combustion in the engine. The fuel filter keeps the fuel free of foreign particles before it gets into the engine. In this way, it protects the engine and ensures an improved longevity. This must also be replaced regularly in order to function reliably.

To replace the air filter and spark plug, it is best to use the practical combination wrench that you received with your STIHL chainsaw. A cardboard hook is integrated in the packaging of the service kit itself. This allows you to easily remove and replace the fuel filter. You do not need any additional tools.
