Your mower is starting harder, running a bit rough, or has lost some punch? A quick home service often fixes it. The STIHL Service Kit 52 gives you the key parts to refresh your petrol mower so it starts easily, runs cleaner and stays reliable for longer.

With an air filter, spark plug and 0.5 l SAE 30 engine oil in one box, you can handle essential maintenance yourself and protect the engine against wear.

Where this kit shines

• Seasonal service before the first mow of spring
• Mid-season refresh to keep fuel use low
• Before winter storage to prevent start-up issues
• After dusty jobs to restore clean airflow

Why it makes a difference

• Clean air filter: improves performance and reduces fuel consumption
• Fresh spark plug: helps easy, dependable starting
• SAE 30 oil: protects against wear with proper lubrication

In everyday use

Swap the air filter and spark plug with the combi spanner supplied with your mower; both jobs take just minutes. When changing oil, a simple funnel or oil suction pump (optional) keeps things neat and avoids spills.
