STIHL Service Kit 23 for FS 80/85, HT 75, KA 85, KM 85, PC 70/75

Your petrol trimmer or combi engine starts harder, uses more fuel or feels down on power? With STIHL Service Kit 23 you can do the simple maintenance that keeps it running clean and reliable: swap the air filter, spark plug and fuel filter in minutes and protect the engine for the long run.

This kit is tailored for selected STIHL FS, HT, KA, KM and PC models. Regularly replacing these wear parts prevents dirt ingress, supports easy starting and helps the engine deliver consistent performance with low fuel consumption.

Where this kit shines

• Season-start refresh for machines that sat in storage
• Quick tune-up before a busy trimming or pruning day
• Proactive care to reduce unexpected downtime
• Operators maintaining multiple identical units

Why it makes a difference

• Clean intake: Fleece air filter traps coarse and fine dust
• Reliable ignition: Fresh spark plug for easy starts
• Protected fuel system: New fuel filter blocks debris
• No extra tools: Use the machine’s combo wrench; cardboard hook included

In everyday use

Swaps are straightforward: remove the old fleece filter, fit the new one, change the plug, then use the included cardboard hook to pull and replace the in-tank fuel filter. No special tools needed—just the combo wrench supplied with your STIHL machine.

Advice from gardenmachineshop.com

After fitting the new air filter, check idle speed and throttle response; a slight carburettor fine‑tune may be beneficial if the old filter was heavily clogged.
