STIHL Service Kit 45 for MS 170 and MS 180 (2-MIX)

If your STIHL chainsaw starts harder, uses more fuel, or feels down on power, a quick home service often fixes it. With the STIHL Service Kit 45 you replace the air filter, spark plug and fuel filter yourself, keeping your MS 170 or MS 180 (2-MIX) running reliably and extending engine life.

This genuine kit is built for simple, no-fuss upkeep. Swap the parts with the saw’s combi wrench; the box even includes a cardboard hook to pull the fuel filter—no extra tools needed.

Where this kit shines

• Season-start tune-up before cutting firewood
• After dusty jobs to restore clean airflow
• Preventive care on frequently used saws
• Keeping a spare set ready for remote work

Why it makes a difference

• Clean intake: Fleece air filter traps coarse and fine dust
• Smooth ignition: Fresh spark plug for reliable starts
• Protected fuel system: Fuel filter blocks debris
• Low effort: Fast DIY swap with your combi wrench

In use: what to expect

Expect easier starting, stable idle and consistent power after fitting the parts. The fleece filter keeps performance up even in dusty cutting, while the new fuel filter and plug help maintain clean combustion and low consumption.

Advice from gardenmachineshop.com

Blow or brush off loose dust around the filter area before opening—keeping debris out of the intake makes your new parts last longer.
