STIHL Service Kit 29 for petrol models

If your STIHL petrol edger, brushcutter, pole hedge trimmer, pole pruner or KombiEngine is getting harder to start or running a bit rough, a quick service often fixes it. With STIHL Service Kit 29 you can replace the key wear parts yourself and keep the engine protected, efficient and easy to start.

This kit brings together the essentials for routine upkeep: a fleece air filter, a spark plug and a fuel filter. Regularly changing these parts helps prevent dust and debris from reaching the engine, so your machine stays reliable for the next job.

Where this kit helps most

• Restoring smooth running after a season of dusty trimming
• Preventive maintenance before peak mowing season
• Quick tune-up to improve starting and throttle response
• Keeping fuel system clean on frequently used tools

Why it makes a difference

• Clean intake, protected engine: Fleece filter traps coarse and fine dust.
• Reliable ignition: Fresh spark plug supports clean combustion.
• Fuel kept debris‑free: New fuel filter safeguards the carburettor.
• DIY friendly: Swap parts with your machine’s combi spanner.

Hands-on use and handling

Use the combi spanner from your STIHL machine to change the air filter and spark plug. A cardboard hook included in the pack lets you pull out and replace the in-tank fuel filter easily—no extra tools needed. Expect a straightforward, 10–15 minute job for most users.

Advice from gardenmachineshop.com

After fitting the new air filter, tap the old one over a bin and note how dusty it is—use that as your cue for how often to service during your season.
